ADVISORY
CIRCULAR DEPARTMENT OF TRANSPORTATION
FEDERAL AVIATION ADMINISTRATION SUBJECT: REPAIR STATION LIMITED RATINGS--BEECH 18 SERIES AIRCRAFT
1. PURPOSE. The purpose of this advisory circular is to advise of a required limited repair station rating to perform X-ray inspection of the Beech 18 Aircraft Wing and Center Section Spar, and the procedures for applicztion. It also provides information concerning certification procedures and operating requirements.
2. REFERENCES. FAR 145, 65, and Airworthiness Directive (AD) 75-27-09 3 . BACKGROUND. Findings of compliance with previous X-ray inspection ADS, (AD-72-20-5, 73-18-4, and 75.09.18), have shown substandard performance.
In many instances X-ray plates were made, interpreted, and given to the owner or operator with the assurance that the aircraft was airworthy.
However, when the plates were evaluated by FAA engineering personnel, or by Beech Aircraft Corporation, the plates showed that cracks existed, or were suspected, or the quality of the plates was such that a satisfactory intespretation could not be made.
4 . NEW AIRWORTHINESS DIRECTIVE. A new AD, 75-27-09, has been published to correct the situation described above. It cancels the previous ADS on this subject and combines all the provisions in one AD. In view of past experience and due to the unique and special inspection procedures described in the directive, it has been determined that only fully qualified facilities and personnel can adequately accomplish the inspections. Accordingly, after July 1,1976, the only maintenance entity that will be authorized to accomplish the X-ray inspections will be an FAA certificated repair station rated as,"Limited Airframe - Beech 18 Series Aircraft - Wing and Center Section Spar X-ray Inspections." It should be pointed out, however, that the X-ray inspection is only one part of the total compliance with the AD. In addition, a visual inspection and either a magnetic particle or penetrant inspection are required. The latter two can be performed and approved for return to service by a properly qualified airframe mechanic or an appropriately rated repair station.
Initiated by: MS-830
5 l PRE-APPLICATION ASSISTANCE. An applicant for this rating should contact the district office having jurisdiction over the area where the repair station has its main base of operation. Early notification and discussions with the district office should enable the applicant to obtain the rating with a minimum of difficulty and delay.
6 l 7 .
APPLICATION. FAA Form 8310-3, Application for Repair Station Certification and/or Rating,is used to apply for this rating.
(See Appendix 1). The applicant completes items 1 through 5.
The following information should prove helpful in selecting the proper method of listing the repair station:
, Item 1A: Official Name of Station An Individual Joe J. Doe d/b/a Daro Aviation Service A Corporation Daro Aviation Service, Inc.
or Daro Aviation Inc. d/b/a Daro Aviation Services A Partnership John J. Doe, Allen B. Smith Richard Roe d/b/a Daro Aviation Service Item 3: Rating Applied For See Appendix 1 Item 4: List of Maintenance Functions Contracted to Outside Agencies Since this is a limited rating to perform a unique and special inspection, special equipment and materials to perform the work are necessary.
The word %one*' should be entered in item 4.
PERSONNEL AND AIR AGENCY QUALIFICATIONS. FAR Section 145.39 requires that a repair station provide adequate personnel who can perform, supervise, and inspect the work for which the station is rated.
Therefore, only those agencies and persons who have demonstrated the capability to reliably perform the inspections set forth in AD 75-27-09 can be authorized to perform these inspections. The applicant is expected to show the ability to satisfactorily perform the required X-ray procedures.
This may be accomplished by presentation of acceptable X-ray films taken per AD 75-27-09 or an AD superseded by AD 75-27-09. To determine the capabilities of personnel, the FAA will provide a set of test X-rays plates for the person to read and interpret using the applicant's viewers and.
facilities. This person may be a certificated mechanic holding an Page 2 Par 5
4122176 AC 145-2 airframe rating or a person who is eligible for a repairman certficate in accordance with the requirements of FAR 65.101 .
8 . INSPECTION SYSTEMS. This is one of the most important parts of a repair station. The applicant and the FAA District Office should work closely to see that a system is developed that produces satisfactory quality control and complies with FAR 145.45. This ' is particularly important in the case of X-ray inspections, since there are so many variables, and past experiences have shown a problem in this area. The applicant for this rating should prepare an inspection procedures manual that contains instructions and procedures for inspection personnel to be thoroughly familiar with all X-ray inspection methods, techniques, and equipment. They should also have available, understand, and comply with the current specific&ions contained in the operations specification of the stat ion.
9 l INSPECTION FOR CERTIFICATION. An applicant should contact the FAA District Office, giving as much lead time as possible to allow for scheduling of inspections. This should be accomplished when the applicant believes that the applicable requirements of FAR 145 have been satisfied.
a. The applicant should present with the application,or as soon as possible thereafter, a set of X-ray films taken by him in accordance with AD 75-27-09 or an AD superseded by AD 75-27-09. If previous X-ray films taken by this facility are not available locally but are on file with the Beech Aircraft Corporation, the applicant should present sufficient data so that FAA can obtain these films for evaluation.
b. The FAA will notify the applicant of the results of the evaluation and, if appropriate, schedule a date for examination of the quali- ' fication of the personnel who will be authorized to review and interpret the films. Any changes in authorized personnel, facilities, repair station equipment, or the inspection procedures established at the time of certification will require FAA evaluation and approval prior to the repair station exercising the privileges of their certificate.
10. REPAIR STATION CERTIFICATE AND OPERATIONS SPECIFICATION. Upon meeting all requirements the FAA District Office will issue an Air Agency Certificate (See Appendix 2) and Repair Station Operations Specification. (See Appendix 3). The operations specifications,in addition to describing the limitations applied to the station, indicate the specification to be used by the station in performing the X-ray inspections. The airworthiness directive is the primary part of the specification. The other part of the specification may be either a civil or military specification currently used by the industry and approved by the Administrator. The Par 7 Page 3
AC 145-Z 4121176 airworthiness directive takes precedence in any conflicting detail between it and any other specification used.
11. MAINTENANCE RECORD ENTRIES. Persons performing X-ray, visual, and magnetic particle or penetrant inspection, should provide the owner or operator of the aircraft with a maintenance record entry that will ' comply with FAR 43.9. When X-ray inspection has been satisfactorily completed by the station, approval for return to service should be made in accordance with FAR 145.59.(a). The person performing the X-ray inspection is also required by this AD to enter the date of letter of authorization issued by the FAA District Office in the maintenance records specifically in FAR 91.173 (a)(Z).
12 0 OTHER RATINGS. Nothing in this advisory circular (AC) should be construed as preventing a repair station with this rating from having other ratings.
This rating can also be added to an existing repair station certificate when all requirements have been met.
