(7) Review or test.
h. Module 8: (40 hours) Glider Class (Class Module). The training provider should make at least one representative aircraft available, or have training aids, mockups, and detailed course presentation materials for use in place of actual LSA. The examples used on the mockups do not need to be in an Airworthy condition but must be complete enough to conduct maintenance and inspection training for this module. If course attendees wish to be rated on gliders with a retractable or fixed engine with a feathering propeller installed, the attendees should also complete Module 3. This module should contain the following:
(1) Theory, operation, and rigging of flight controls.
(2) Inspection and minor repair to fabric covering on wings, fuselage, and tail surfaces.
(3) Use of manufacturer’s manuals and technical data during projects.
(4) Identification and inspection of critical areas.
(5) Inspection and minor repairs to applicable airframe structures.
(6) Ballistic parachutes: theory, installation, operation, and inspection.
(7) Inspection and maintenance of wheels and brakes and wheel retract systems.
(8) W&B.
(9) Inspection of the wing folding/removal mechanism.
(10) Review or test.
125. THE MAINTENANCE RATING MODULAR TRAINING SYSTEM.
a. Training Completion. To complete the training required for the issuance of repairman (LSA) certificate with a maintenance rating for a particular class of aircraft, an applicant should complete the following modules as appropriate:
(1) Airplane. Modules 1, 2, 3, and 4 for a total of 120 hours of instruction.
(2) Weight-Shift-Control Aircraft. Modules 1, 2, 3, and 5 for a total of 104 hours of instruction.
(3) Powered Parachute. Modules 1, 2, 3, and 6 for a total of 104 hours of instruction.
(4) Lighter-Than-Air. Modules 1 and 7 for a total of 80 hours of instruction.
(5) Glider. Modules 1, 2, and 8 for a total of 80 hours of instruction. If the repairman intends to maintain powered gliders, module 3 should also be taken for a total of 125 hours of instruction. To obtain a glider or powered glider in addition to an airplane (1) rating they must Page 22 Par 124
Par 125 Page 23 complete airplane Modules 1, 2, 3, 4, and Module 8 parts 1, 3, 4, 7, 9, 10 for a total 139 hours of instruction.
b. Additional Class Ratings. This system allows a repairman with the maintenance rating limited to airplane, weight-shift-control aircraft, lighter-than-air, or glider class to obtain an additional class ratings (e.g., powered parachutes) by taking only Module 6 (19 hours of instruction) rather than 80 hours required for the original rating. A repairman (LSA) who applies for another rating must take his or her original certificate of completion for the training used to obtain his or her original rating, plus the new certificate of completion to the local FSDO. After review, the applicant will be issued a new repairman certificate with the maintenance rating showing both the original class rating and the new class rating.
126. PERFORMANCE OF MAJOR REPAIRS AND MAJOR ALTERATIONS BY A REPAIRMAN (LSA) WITH A MAINTENANCE RATING. A repairman may not perform a major repair or major alteration on a product produced under an FAA approval. However, prior to performing a major repair on a product not produced under an FAA approval, the repairman may need to complete additional training acceptable to the FAA and appropriate to the work performed. This training may consist of additional training in areas such as welding, overhauls, engine gear reduction units, major repairs to structures, or major repairs to fabric. For example, if a repairman with a maintenance rating successfully completed an LSA engine manufacturer’s course in overhaul of a particular make and model engine or gear reduction unit or an LSA manufacturer’s course that teaches welding of steel or aluminum structures, he or she would be permitted to perform major repairs to those manufacturers’ products (see definitions (major repairs and alterations)).
127. APPLYING FOR A REPAIRMAN (LSA) CERTIFICATE. To apply for a repairman (LSA) certificate with either an inspection or maintenance rating, the applicant must present the following documentation to his or her local FSDO:
a. Photo Identification. A valid U.S. driver’s license, passport, or other documentation that will show the applicant meets the age and citizenship eligibility requirements for the certificate.
b. Complete FAA Form 8610-2, Airman Certificate and/or Additional Rating Application. A sample of the completed form is in Appendix 2, Repairman (Light-Sport Aircraft) Certification. FAA Form 8610-2 is available at your local FSDO or at:
http://www.faa.gov/forms. The applicant can find a list of the locations for each local FSDO at:
www.faa.gov/about/office_org/field_offices/fsdo. (See Appendix 2, Figure 1, Sample FAA Form 8610-2, Repairman (Light-Sport Aircraft) Application (Inspection Rating) (Front Side) and Figure 2, Sample FAA Form 8610-2, Repairman (Light-Sport Aircraft) Application (Inspection Rating) (Reverse Side) for a sample application for an inspection rating. See Appendix 2, Figure 3, Sample FAA Form 8610-2, Repairman (Light-Sport Aircraft) Application (Maintenance Rating) (Front Side) and Figure 4, Sample FAA Form 8610-2, Repairman (Light-Sport Aircraft) Application (Maintenance Rating) (Reverse Side) for a sample application for a maintenance rating.)
c. Proof of Training. Show proof of completion of training, which confirms that you have received appropriate training for the rating sought. Proof of training would be a certificate of training or graduation. The certificate of training should contain:
(1) An FAA course acceptance number;
(2) The name of the organization providing the training;
(3) Hours of training received;
(4) Name of the primary instructor;
(5) Name of the course;
(6) Make and model of aircraft, if for inspection rating, or name of category of LSA for maintenance rating; and
(7) The date you received the instruction.
d. Proof of Ownership. To apply for a repairman certificate with an inspection rating, the applicant must show proof of ownership of an aircraft in the class of LSA for which he or she received training. Upon review and acceptance of the documentation, an FAA inspector will issue a temporary repairman certificate (LSA) with the applicable rating. (See Appendix 2, Figure 5, Sample FAA Form 8060-4, Temporary Airman Certificate (Inspection Rating, Weight-Shift-Control Aircraft) and Figure 6, Sample FAA Form 8060-4, Temporary Airman Certificate (Maintenance Rating, Weight-Shift-Control Aircraft).)
e. Lack of Applicable LSA. If the applicant completes a course for a repairman (LSA) certificate with an inspection rating but does not yet own an applicable LSA, the certificate will not be issued.
f. Selling the Aircraft. If the holder of the repairman certificate “inspection” under § 65.107 sells his or her aircraft, the repairman certificate becomes void. If he or she purchases another same class LSA certificated under § 21.191(i), the holder can take the original training certificate to the FSDO and have a repairman certificate issued for the same class of aircraft.
If he or she purchases an LSA in another class, the repairman would have to receive the 16 hours of approved training for the new class of aircraft owned to be issued a repairman “inspection” certificate under § 65.107.

201. TESTING PROCEDURES FOR THE REPAIRMAN (LSA) COURSE WITH A MAINTENANCE RATING. The maintenance course for each of the 5 classes of SLSA should contain at least a knowledge test with 100 multiple choice questions. Each final test should be further subdivided into three broad areas: regulatory, technical, and recordkeeping. The course provider should administer the final test to each student and grade the test. The passing grade should be no less than 80 percent. Once the student has passed the knowledge test and demonstrated the skills necessary to be a repairman, the course provider should issue a certificate of completion. The person receiving the certificate of completion may then present the certificate of completion (with the appropriate course number on the certificate), photo identification, proof of age, and citizenship (described in paragraph 127a) to the local FSDO. Upon review of the documentation, and determination of compliance with regulatory requirements, the FAA will issue a repairman (LSA) certificate with a maintenance rating.
202. TERM OF VALIDITY FOR REPAIRMAN (LSA) CERTIFICATES WITH INSPECTION OR MAINTENANCE RATINGS.
a. End of Ownership or Operation. The repairman (LSA) certificate with an inspection rating is valid until the repairman no longer owns or operates the LSA identified on his or her certificate or the certificate is surrendered, suspended, or revoked. The repairman (LSA) certificate with a maintenance rating is valid until the certificate is suspended, surrendered, or revoked.
b. Transfer of Ownership. If a repairman with an inspection rating transfers ownership of the aircraft that is identified on his or her repairman certificate, he or she can no longer perform annual condition inspections on that aircraft. If the repairman buys a replacement aircraft in the same class as the original aircraft, he or she can request that his or her local FSDO re-issue the repairman certificate with the registration and serial number of the new aircraft.
203. TERM OF VALIDITY FOR FAA ACCEPTANCE OF INSPECTION AND MAINTENANCE RATING TRAINING COURSES. The FAA will only list a training course as acceptable for 24 calendar-months. At least 60 days prior to the end of the 24 calendar-month period, a training provider should provide the FAA with any revisions to the information previously provided in order for a course to remain listed as acceptable.
204. LEVEL OF TRAINING. Both the inspection and maintenance rating courses provide instruction at instructional level 3. Appendix A of part 147 identifies level 3 performance as a level where a student can perform the task by demonstrating a high level of skill.

CHAPTER 3. CONTINUED AIRWORTHINESS OF EXPERIMENTAL AND SPECIAL
LIGHT-SPORT AIRCRAFT
300. CONTINUED AIRWORTHINESS. Continued airworthiness is a term used to describe the result of maintenance and preventive maintenance performed on an aircraft to maintain it in a condition for safe operation. Continued airworthiness is required to maintain the validity of an aircraft’s airworthiness certificate. The aircraft’s operating limitations also require continued airworthiness. The amount of continued airworthiness tasks owners/operators must perform to maintain an aircraft’s airworthiness depends on the light-sport category in which the aircraft is certificated. ASTM F2295, Standard Practice for Continued Operational Safety Monitoring of a Light Sport Aircraft, is the standard practice for continued operation safety monitoring of a LSA.
301. ELSA. LSA that are issued an experimental certificate under § 21.191(i) have no established FAA or industry design standards to meet other than those standards identified in the aircraft’s operating limitations. Operating limitations are a permanent part of the aircraft’s Special Airworthiness Certificate and must remain in the aircraft during operation. Aircraft certificated under § 21.191(i)(2) and (i)(3) would have a maintenance manual with inspections required at certification, see § 21.193(e).
302. SLSA. To be issued an airworthiness certificate in the light-sport category under § 21.190, an aircraft must meet an industry-developed consensus standard acceptable to the FAA, which addresses aircraft design, production, and airworthiness. The aircraft’s operating limitations address its continued airworthiness. The aircraft manufacturer has the authorization to make changes, issue safety directives, and approve major repairs and alterations in accordance with the ASTM standard the aircraft was built to at certification. The Aircraft Maintenance Manual (AMM) lists the persons authorized to perform maintenance and inspections including the training required to perform a specific task. All maintenance on an SLSA has to be done by persons certificated under part 65 in accordance with part 43 except the recording of major repairs and alterations on non-FAA-approved products.
303. CONTINUED AIRWORTHINESS REQUIREMENTS FOR ELSA.
a. Details. There are continued airworthiness requirements for aircraft issued experimental certificates for the purpose of operating LSA. The operating limitations issued with the ELSA airworthiness certificate include these requirements. These requirements ensure that the aircraft continues to be in a condition for safe operation. Part 43 does not apply to an ELSA certificated under § 21.191(i). Non-FAA-certificated persons can accomplish maintenance on an ELSA.
(1) Annual Condition Inspection. This is a detailed, in-depth inspection, performed once every 12-calendar months, of the aircraft and all of its component parts. If the inspection is overdue, the aircraft cannot be flown until an appropriately rated, part 65 certificated person has inspected the LSA and has made the required entry in the aircraft’s maintenance records stating that the aircraft is in a condition for safe operation.
(2) Annual Condition Inspection Checklist. The inspection checklist may be one designed by the manufacturer of the aircraft or one developed by a certificated person performing the inspection. The inspection checklist must meet the scope and detail of part 43, Par 300 Page 29
appendix D. The inspection checklist in AC 90-89, Amateur-Built Aircraft and Ultralight Flight Testing Handbook, Appendix 1, meets the scope and detail of part 43, appendix D and is highly recommended as a guide to develop an inspection checklist for individual makes and models of fixed wing aircraft.
(3) The annual condition inspection must be performed by:
(a) A repairman (LSA) with either an inspection rating on his own aircraft limited to his repairman certificate issued under § 65.107, or with a repairman maintenance rating for the class of aircraft that the repairman is inspecting.
(b) A mechanic with an A&P rating.
(c) An appropriately rated FAA repair station.
(4) The certificated person performing the inspection must record it in the aircraft’s maintenance records in accordance with the inspection statement in the aircraft’s operating limitations. (See Appendix 1, Figure 1, Sample Entry for Annual Condition Inspection for an Experimental Light-Sport Aircraft (ELSA)).
NOTE: If a major malfunction or defect is found during the annual condition inspection, it is strongly recommended that the repairman, mechanic, or repair station report the problem to the FAA and to http://av-info.faa.gov/sdrx within 72 hours for any FAA TC product, also have the aircraft owner report the program to the aircraft’s manufacturer for any other part, assembly or product produced in accordance with the ASTM and the aircraft manufacturer. The LSA maintenance manual will have instruction for the report.
b. Major Alterations. If the aircraft is issued an ELSA certificate, a non-certificated person may perform additional maintenance, preventive maintenance, or alterations on the aircraft. If a non-certificated person performs a major alteration, as defined by § 1.1
(e.g., changing the engine to another model that increases the original engine horsepower by 10 percent or more), he or she must make a maintenance record entry and a new FAA Form 8130-6, Application for U.S. Airworthiness Certificate, and send it to the FAA Aircraft Registration Branch (AFS-750). A new FAA Form 8130-6 is required because he or she has modified the aircraft and it is no longer the same aircraft as identified on the original FAA Form 8130-6 in the aircraft’s file. A Designated Airworthiness Representative (DAR) or FAA aviation safety inspector (ASI) will review the change(s) and issue new operating limitations for the aircraft. The issued operating limitations may require the aircraft to be put in a flight test area for a certain number of hours until the owner/operator has flight tested the new alteration and the aircraft is proven to be safe to operate within its design envelope. When the flight-testing is complete, the test pilot should sign the aircraft off as safe-to-fly in accordance with its operating limitations. (See Appendix 1, Figure 2, Sample of a Major Alteration Entry for an Experimental Light-Sport Aircraft (ELSA)).
Page 30 Par 303
Par 303 Page 31
c. Major Repairs. If any person performs a major repair on an ELSA, he/she should record that repair and the description of the data used to make the repair in the aircraft’s maintenance records for future reference. It is strongly recommended that persons performing major repairs to an aircraft report any malfunction or defect concerning the aircraft to the FAA at http://av-info.faa.gov/sdrx and to the aircraft’s manufacturer. (See Appendix 1, Figure 3, Sample of a Major Repair Entry for an Experimental Light-Sport Aircraft (ELSA)).
d. Maintenance. Any person may perform maintenance on an ELSA. (See Appendix 1, Figure 4, Sample of a Maintenance Record Entry for an Experimental Aircraft (ELSA)).
304. CONTINUED AIRWORTHINESS REQUIREMENTS FOR SLSA. An aircraft issued an SLSA airworthiness certificate under § 21.190 was designed, built, and certified in accordance with an industry consensus standard acceptable to the FAA. This standard is identified on the manufacturer’s Statement of Compliance that is part of the aircraft’s records.
Due to design and production standards for SLSA, there are additional requirements for continued airworthiness to ensure the owner/operator maintains these aircraft in a condition for safe operation. For example, a certificated repairman or mechanic under part 65 must perform an annual condition inspection within 12 calendar-months. Also, the operating limitations may require the manufacturer to establish additional maintenance requirements. Examples of additional requirements concern compliance with safety directives issued by the manufacturer for non-FAA-approved products and ADs which may be issued for FAA-approved TC products installed on the aircraft. For TCs, see § 21.11. In accordance with part 43 owners/operators must accomplish these directives and any other maintenance. In addition, if using the SLSA for compensation or hire to tow a glider or to conduct flight training, the aircraft must have an additional inspection after every 100 hours of operation and recorded in the aircraft maintenance record.
NOTE: For FAA information on LSA, visit the FAA aircraft Web site at http://www.faa.gov/aircraft/gen_av/light_sport. The page has a lot of information including the list of certificated aircraft that can be flown with light-sport privileges. It also includes a list of the accepted FAA ASTM standards for SLSA certification.
305. REQUIREMENTS FOR SLSA CONDITION INSPECTIONS. Section 91.327, Aircraft having a special airworthiness certificate in the light-sport category: Operating limitations.
a. Operating Limitations. The aircraft operating limitations will require that the owner/operator perform a condition inspection within 12 calendar-months for an SLSA.
(1) A certificated repairman with a LSA maintenance rating, an appropriately rated mechanic, an appropriately rated repair station (in accordance with the applicable provisions of part 43 of this chapter and maintenance and inspection procedures developed by the aircraft manufacturer), or a person acceptable to the FAA, is required to maintain the aircraft.
(2) Once every 12 calendar-months, a certificated repairman (LSA) with a maintenance rating, an appropriately rated mechanic, an appropriately rated repair station (in accordance with inspection procedures developed by the aircraft manufacturer), or a person acceptable to the FAA performs a condition inspection.
b. Annual Condition Inspection Maintenance Record Entry. A sample annual condition inspection maintenance record entry for an SLSA is shown in Appendix 1, Figure 5, Sample of Annual Condition Inspection for a Special Light-Sport Aircraft (SLSA).
c. Additional Mandatory Maintenance Requirements for SLSA. In addition to the annual condition inspection, there may be additional mandatory maintenance requirements for SLSA. These additional requirements may take the form of, but are not limited to, manufacturer’s safety directives for non-FAA-approved products and/or ADs issued against FAA-approved products installed on the aircraft. Maintenance providers will note these additional maintenance requirements to be accomplished by the owner/operator as authorized in the aircraft operating limitations issued with the aircraft’s SLSA airworthiness certificate.
306. MAINTENANCE AND ALTERATION OF SLSA.
a. Maintenance and Alterations. Any maintenance or alteration that the repairman, mechanic, or repair station performs on an SLSA, they must accomplish using data supplied by the manufacturer and performed by a repairman (LSA) with a maintenance rating, a mechanic with an A&P rating, or a repair station appropriately certificated for that class of SLSA in accordance with part 43.
b. Preventive Maintenance. The holder of any pilot certificate may perform preventive maintenance on an SLSA; however, the holder of a sport pilot certificate may only perform preventive maintenance on an aircraft owned or operated by that pilot, unless prohibited by the aircraft’s operating limitations.
c. Major Repairs. Persons that can perform maintenance, major repairs or alterations.
A certificated repairman with an LSA maintenance rating, an appropriately rated mechanic, or an appropriately rated repair station in accordance with the applicable provisions of part 43 of this chapter and maintenance and inspection procedures developed by the aircraft manufacturer or a person acceptable to the FAA.
d. Additional Training. To perform a major repair, a repairman (§ 65.107) with a maintenance rating, a mechanic with an A&P rating, or appropriately certificated repair station, may be required by the aircraft manufacturer to receive additional training. This training should be from either the manufacturer or from an industry-accepted training provider. A person certificated under § 65.71 who has received the task specific training and has the tools, manuals, and the required information from the aircraft manufacturer for the major repair or alteration may also provide any task-specific training. The aircraft manufacturer may require a level of certification of maintenance personnel to perform the major repair or alteration. (Refer to Appendix 1, Figure 6 and ASTM F2483 and F2295 for maintenance procedures.)
Page 32 Par 305
Par 306 Page 33 (and 34) NOTE: Any person performing a major repair should report malfunctions or defects of TC’d products to the FAA at http://av-info.faa.gov/sdrx within 72 hours, and components built to ASTM standard to the aircraft’s manufacturer as per the manufacturer’s maintenance manual instructions.
e. Major Alterations. If the owner wants a major alteration such as a new engine/propeller combination installed on the aircraft, the owner must obtain the manufacturer’s consent and all applicable data prior to making the alteration. (See Appendix 1, Figure 7, Sample of How to Record a Major Alteration in the Aircraft Maintenance Records for a Special Light-Sport Aircraft (SLSA)).
(1) If the manufacturer issues a mandatory safety directive and the owner of the SLSA does not wish to comply with the directive, then the owner of the aircraft may not operate the aircraft before accomplishing the action specified in the directive.
(2) The owner may surrender the SLSA airworthiness certificate to the FAA or its representative and apply for an ELSA airworthiness certificate (§ 21.191(i)(3)) with new operating limitations for the aircraft if the aircraft owner does not accomplish compliance with the safety directive and the owner intends to continue to operate the aircraft. The owner can accomplish this action by filling out a new FAA Form 8130-6 and submitting it to the local FSDO. Upon review, the aircraft will be issued new operating limitations, which will limit the now ELSA aircraft from flight instruction. See the current edition of FAA Order 8130.2, Airworthiness Certification of Aircraft and Related Products, for instructions.
307. REPAIRMAN (LSA) WITH A MAINTENANCE RATING: REPLACEMENT OF A PROPELLER ON AN SLSA AND AIRCRAFT MAINTENANCE RECORDS.
Replacement of a propeller on an SLSA with one of the same manufacturer model/part number, pitch, and diameter is a maintenance action requiring a standard logbook entry. Replacement of a propeller having a different pitch and/or diameter is a major alteration, and the SLSA manufacturer must approve that major alteration. The maintenance provider must record a copy of the manufacturer’s approval and a maintenance entry describing the removal and installation of the new propeller in the aircraft records. (See Appendix 1, Figure 7).
