                       Subpart B_Type Certificates

 

Sec. 21.35  Flight tests.



    (a) Each applicant for an aircraft type certificate (other than 

under Sec. Sec. 21.24 through 21.29) must make the tests listed in 

paragraph (b) of this section. Before making the tests the applicant 

must show--

    (1) Compliance with the applicable structural requirements of this 

subchapter;

    (2) Completion of necessary ground inspections and tests;

    (3) That the aircraft conforms with the type design; and

    (4) That the Administrator received a flight test report from the 

applicant (signed, in the case of aircraft to be certificated under Part 

25 [New] of this chapter, by the applicant's test pilot) containing the 

results of his tests.

    (b) Upon showing compliance with paragraph (a) of this section, the 

applicant must make all flight tests that the Administrator finds 

necessary--

    (1) To determine compliance with the applicable requirements of this 

subchapter; and

    (2) For aircraft to be certificated under this subchapter, except 

gliders and except airplanes of 6,000 lbs. or less maximum certificated 

weight that are to be certificated under Part 23 of this chapter, to 

determine whether there is reasonable assurance that the aircraft, its 

components, and its equipment are reliable and function properly.

    (c) Each applicant must, if practicable, make the tests prescribed 

in paragraph (b)(2) of this section upon the aircraft that was used to 

show compliance with--

    (1) Paragraph (b)(1) of this section; and

    (2) For rotorcraft, the rotor drive endurance tests prescribed in 

Sec. 27.923 or Sec. 29.923 of this chapter, as applicable.

    (d) Each applicant must show for each flight test (except in a 

glider or a manned free balloon) that adequate provision is made for the 

flight test crew for emergency egress and the use of parachutes.

    (e) Except in gliders and manned free balloons, an applicant must 

discontinue flight tests under this section until he shows that 

corrective action has been taken, whenever--

    (1) The applicant's test pilot is unable or unwilling to make any of 

the required flight tests; or

    (2) Items of noncompliance with requirements are found that may make 

additional test data meaningless or that would make further testing 

unduly hazardous.

    (f) The flight tests prescribed in paragraph (b)(2) of this section 

must include--

previously used in a type certificated aircraft, at least 300 hours of 

operation with a full complement of engines that conform to a type 

certificate; and

    (2) For all other aircraft, at least 150 hours of operation.
