Standard Specification for Structural Durability for Small Airplanes
|Publication Date:||1 June 2015|
|ICS Code (Aircraft and space vehicles in general):||49.020|
1.1 This specification addresses the airworthiness requirements related to structural durability for the design of small airplanes.
1.2 This specification was originally conceived for small airplanes as defined in the F44 terminology standard but may find broader applicability. Use of the term aircraft throughout this specification is intended to allow the relevant CAA(s) to accept this standard as a means of compliance as they determine it to be appropriate, whether for small airplanes or for other types of aircraft.
1.3 The applicant for a design approval must seek individual guidance from their respective CAA body concerning the use of this standard as part of a certification plan. For information on which CAA regulatory bodies have accepted this standard (in whole or in part) as a means of compliance to their Small Airplane Airworthiness Rules (hereinafter referred to as "the Rules"), refer to ASTM F44 webpage (www.ASTM.org/COMMIT
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This specification is concerned with the airworthiness requirements related to structural durability for the design of small airplanes. The applicant for a design approval must seek individual guidance from their respective civil aviation authority (CAA) body regarding the use of this specification as part of a certification plan.
This specification covers metallic structures such as pressurized cabin structures and wing, empennage, and associated structures that must be able to withstand the repeated loads of variable magnitude expected in service. These structures, as well as composite and bonded structures, must also conform to specified requirements for fatigue strength, fail safe strength, damage tolerance, and residual strength.View Less
