Damage Tolerance and Fatigue Evaluation of Composite Rotorcraft Structures

This proposal would revise airworthiness standards for type certification requirements of normal and transport category rotorcraft. The amendment would require evaluation of fatigue and residual static strength of composite rotorcraft structures using a damage tolerance evaluation, or a fatigue evaluation, if the applicant establishes that a damage tolerance evaluation is impractical. The amendment would address advances in composite structures technology and provide internationally harmonized standards.
