8.8 Crewmember Records. Crewmember records for PIC, SIC, FE, flight navigator, and F/A will be kept in accordance with § 125.401(a) through (c).

8.9 Meeting Testing Requirements and Recency of Experience.

8.9.1 Twelve-Month Check. (Refer to § 125.287.)

8.9.1.1 Written or Oral Tests. All pilots are required to complete a written or oral test of the subjects listed in § 125.287(a) for each type of airplane in which

8-5 they perform in a pilot capacity initially and every 12 calendar-months thereafter. Those who maintain this qualification on more than one airplane will be subject to the knowledge items in § 125.287(a)(2), (3), and (8) for each type of airplane.

Note: See Chapter 4, paragraph 4.11, Testing of Crewmembers, for information on electronic testing systems (ETS) for satisfying the requirements of § 125.287(a)(1) and (4) through (9).

8.9.2 Flight Test. All pilots are required to satisfactorily complete the competency check required by § 125.287(b) for each type of airplane in which they perform in a pilot capacity initially and every 12 calendar-months thereafter. The extent of that competency check shall be determined by the Administrator or authorized check pilot. The competency check may include any of the maneuvers and procedures currently required for the original issuance of the particular pilot certificate required for the operations authorized and appropriate to the category, class, and type of airplane involved.

8.9.3 Flight Check Job Aid. The job aid for a competency flight check can be found on the FAA’s Web site at http://fsims.faa.gov. It should be used by the evaluator to assure all areas required by § 125.287 are covered. FAA Form 8410-1, Airman Proficiency/Qualification Check, is used to determine which specific maneuvers are to be performed, and should be used to indicate whether the maneuvers are satisfactory, unsatisfactory, or waived. The objective standards for the maneuvers are found in either the commercial pilot practical test standards (PTS) or Airman Certification Standards (ACS), as applicable, or the airline transport pilot (ATP) and aircraft type rating PTS or ACS, as appropriate. When the job aid for a competency flight check is used, consider the following information:

8.9.3.1 Use of Checklists. The inspector must note that the flightcrew members not only use all appropriate checklists, but also adhere to their provisions.

8.9.3.2 Crew Coordination. The emphasis is on adherence to company procedures included in the Policy and Procedures Manual (PPM), and accepted cockpit management methods.

8.9.3.3 Takeoffs. Takeoffs, for the purpose of the competency check, begin when the airplane is taxied into position on the runway to be used.

8.9.3.3.1 Crosswind takeoffs should be considered only when meteorological, airport, and traffic conditions allow them to be done safely. If not, crosswind technique can be discussed during the oral or written portion of the check.

8.9.3.3.2 The takeoff with a simulated failure of the most critical engine may be performed in a nonvisual simulator. When to induce the powerplant failure is up to the judgment of the inspector, given the airplane type and the prevailing conditions.

8-6

8.9.3.3.3 The rejected takeoff may be performed during a normal takeoff roll after reaching a reasonable speed. A reasonable speed is determined by considering airplane characteristics, runway length, surface conditions, wind direction and velocity, brake energy limits, and any other pertinent factors that may adversely affect safety. This speed should be no more than 50 percent of the takeoff decision speed (V1).

8.9.3.3.4 Steep turns must be performed at a bank angle of 45°. The turn must be at least 180° and not more than 360°.

8.9.3.3.5 For the purpose of the check, the required approach to a stall is reached when there is a perceptible buffet or activation of stall warning devices (stick shaker or pusher). Where the airplane uses only a zero-flap takeoff configuration, stalls in the takeoff configuration may be omitted. At the discretion of the person conducting the check, one approach to a stall can be performed in one of the configurations while in a turn with a bank angle between 15° and 30°. If the certificate holder is authorized to operate the airplane with any stall warning device or indicator inoperative, the device or indicator may not be used during this maneuver.

8.9.3.4 Flight Characteristics Peculiar to the Airplane Type. Proper control of airspeed, configuration, direction, altitude, and attitude must be in accordance with procedures and limitations in the FAA-approved AFM, the operator’s PPM, checklists, or other approved material appropriate to the airplane.

8.9.3.5 Powerplant Failures. In addition to the specific maneuvers to be demonstrated with an inoperative powerplant, the person conducting the check may require a simulated powerplant failure at any time during the check.

8.9.3.6 Landings. At least two actual landings are required, but the conditions may be combined, as appropriate.

8.9.3.6.1 Crosswind landings may be conducted only if existing meteorological, airport, and traffic conditions allow. If not, discussion of the technique can be included in the oral or written portion of the check.

8.9.3.6.2 The following are conditions for maneuvering to a landing with simulated powerplant failure:

• In the case of three-engine airplanes, a procedure that approximates the loss of two powerplants (center and one outboard), or

• In the case of other multiengine airplanes, a simulated failure of 50 percent of available powerplants with the simulated power loss on one side of the airplane (not to be done on a circling approach).

• The landing that is rejected must be approximately 50 feet above the runway and approximately over the runway threshold.

8-7

8.9.3.7 Normal and Abnormal Procedures. The pilots being tested must demonstrate the proper use of as many systems and devices as the person conducting the check finds are necessary to indicate the required proficiency.

A rejected landing may be combined with instrument circling approach or Missed Approach Procedures (MAP).

8.9.3.8 Emergency Procedures. The pilots being tested must demonstrate the proper emergency procedures for as many of the possible emergency situations as the person conducting the check finds are necessary to indicate adequate knowledge and skill. If any emergency situations cannot be simulated, include these procedures in the oral or written portion of the test.

8.9.4 Emergency FE Functions. Those pilots the certificate holder wants qualified to perform emergency FE functions per § 125.263(c) will be required to demonstrate the knowledge and skill to perform these functions for an authorized representative of the Administrator.

1. This qualifying check may be administered in an airplane of the appropriate type on the ground.

2. It may be given in conjunction with the 12-month check or the IPC in that airplane.

3. The qualifying check will cover all anticipated critical situations with respect to the fuel, electric, hydraulic, and environmental systems, and any other function of the FE critical to the safe operation of that particular airplane.

4. The results of this check will be entered on an FAA Form 8410-1. Those items listed under “Flight Engineer” which were checked will be graded and an entry will be made under “Remarks” stating the results of that test;

e.g., “Satisfactorily demonstrated emergency flight engineer functions per § 125.263(c).”

8.9.5 Six-Month Instrument Proficiency Check (IPC). (Refer to § 125.291.)

8.9.5.1 General. All persons who serve as PIC under IFR of an airplane during part 125 operations must satisfactorily complete the IPC outlined in § 125.291 initially and every 6 calendar-months thereafter.

8.9.5.2 Flight Test. A pilot must take this check in the type(s) of airplanes which the certificate holder has assigned him/her to perform pilot duties under part 125.

If that person is only assigned to one type of airplane, the check must be accomplished in that type (refer to § 125.291(d)). If a pilot is assigned to more than one type of airplane, the check will be done on a rotational basis, but not more than one flight check during each 6-calendar-month period (refer to § 125.291(e)). For example, a pilot assigned to an A-320, B-737, and L-382, whose first IPC was in June 2015 in the A-320, could take the check due in December 2015 in the B-737, and the June 2016 check in the L-382. He/she would not be allowed to use just one of the aircraft to take successive IPCs.

8-8

8.9.5.3 Contents of Check. The IPC will consist of an oral or written equipment test for the type of airplane and a flight check under simulated or actual IFR conditions (refer to § 125.291(c)). The general content of the equipment check and flight check is included in § 125.291(c). The check will include the procedures and maneuvers for a commercial pilot certificate with an instrument rating and, if required, for the appropriate type rating (refer to § 125.291(c)(1)).

8.9.5.4 Forms Issued. A letter of competency will be issued to the pilot upon successful completion of the IPC. This letter will contain a list of the types of IAPs and facilities authorized (refer to § 125.291(g)). This letter will constitute an authorization for the pilot to perform PIC duties under IFR during operations under part 125. An FAA Form 8410-1 will also be issued showing successful completion of the checks required by § 125.287 (refer to § 125.287(c)).

8.9.6 Flight Attendant (F/A) Testing.

8.9.6.1 F/As may not be used if they have not been tested in the preceding 12 calendar-months by the certificate holder on the areas listed in § 125.289.

8.9.6.2 The certificate holder should develop a test (refer to § 125.289) which will determine that the F/As are knowledgeable and competent to perform their assigned duties and responsibilities as outlined in § 125.289(a) through (i).

This test can be a combination of written and oral questions, and procedures to be performed or simulated. The certificate holder will maintain at least one copy of all test questions, written and oral, and list of procedures which are performed as a part of this test.

8.9.6.3 The results of each F/A’s performance on this test will be inserted in the crewmember’s record. Each attendant should be issued a memo which contains the certificate holder’s name, the date of the test, and a statement that this named F/A has satisfactorily completed the certificate holder’s test.

8.10 Use of Simulators.

8.10.1 Approved Simulators. Section 125.297(a) provides for the use of approved simulators for the checks required by part 125 subpart I. Sections 125.287(f) and 125.291(f) provide for the FAA to approve the use of a simulator or other appropriate training device to give portions of the 12-month check and the IPC. Section 125.285(c), with some limitations, provides for the use of a visual simulator to meet the recent experience requirements outlined in § 125.285(b).

8.10.2 Requirements. Each simulator and flight training device (FTD) that is used in training, testing, and checking, required under part 125, must be used in accordance with an approved training course conducted by a training center certificated under 14 CFR part 142 or meet the requirement specified in § 125.297(b)(1) through (3).

8-9

8.10.3 Inoperative Simulators. Should the simulator or FTD become inoperative, out of tolerance for the applications approved, or otherwise unavailable for the checks authorized, the check maneuvers may be accomplished in the airplane.

8.11 Authorization of a Check Airman.

8.11.1 Types of Checks. Part 125 provides for the authorization of a check airman to perform some or all of the checks required in part 125 subpart H or I (refer to § 125.295). The checks which a check airman may be authorized to perform are:

1. Twelve-month checks required by § 125.287.

2. IPCs required by § 125.291.

3. FE familiarization checks required by § 125.265(b) and the emergency FE function checks given to pilots per § 125.263(c).

4. Recent experience observations required by § 125.285(b) and (c)(2)

8.11.2 Approval Requests. Request for approval of a check airman should be submitted, in letter form, by the operator, to the certificate-holding district office (CHDO).

8.11.2.1 The letter of request constitutes the operator’s nomination. It originates from the operator, not a training center, candidate, or some other party. It will include:

• Candidate’s name;

• Business address;

• Applicable airman’s certificate number;

• Current flightcrew member position;

• Requested check pilot or check FE classification;

• Airplane type;
