Fatigue Tolerance Evaluation of Metallic Structures
type: GovernmentService
description: This rule amends the airworthiness standards for fatigue tolerance evaluation (FTE) of transport category rotorcraft metallic structures. This revises the FTE safety requirements to address advances in structural fatigue substantiation technology for metallic structures. This provides an increased level of safety by avoiding or reducing the likelihood of the catastrophic fatigue failure of a metallic structure. These increased safety requirements will help ensure that should serious accidental damage occur during manufacturing or within the operational life of the rotorcraft, the remaining structure could withstand, without failure, any fatigue loads that are likely to occur, until the damage is detected or the part is replaced. Besides improving the safety standards for FTE of all principal structural elements (PSEs), the amendment is harmonized with international standards.
