                     Subpart C_Strength Requirements

 

Sec. 29.307  Proof of structure.



    (a) Compliance with the strength and deformation requirements of 

this subpart must be shown for each critical loading condition 

accounting for the environment to which the structure will be exposed in 

operation. Structural analysis (static or fatigue) may be used only if 

the structure conforms to those structures for which experience has 

shown this method to be reliable. In other cases, substantiating load 

tests must be made.

    (b) Proof of compliance with the strength requirements of this 

subpart must include--

    (1) Dynamic and endurance tests of rotors, rotor drives, and rotor 

controls;

    (2) Limit load tests of the control system, including control 

surfaces;

    (3) Operation tests of the control system;

    (4) Flight stress measurement tests;

    (5) Landing gear drop tests; and

    (6) Any additional tests required for new or unusual design 

features.
