Why New DAH Approach?
Two approaches for addressing safety issues:Airworthiness DirectivesGeneral rulemakingOperators have expressed concerns aboutthe timely availability of data to supportcompliance with operational rulesVoluntary Support ProblemsAs a result, the FAA has determined that Design Approval Holder (DAH) requirements will be adopted as necessary to support certain future safety initiatives which will be implemented via operational rules

Enhanced Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS)In part, it requires DAH to develop Electrical Wiring Interconnection System (EWIS) Instructions for Continued Airworthiness (ICA)Aging Airplane Safety Rule (AASR)Requires DAH to develop damage tolerant inspection instructions for continued airworthinessFuel Tank FlammabilityRequires DAH to develop flammability exposure analyses of fuel tank. High risk fuel tanks require new design changes and ICA.Widespread Fatigue Damage (WFD) - PROPOSEDRequires DAH to establish a Limit of Validity of the engineering data that supports the maintenance program.

DAH Rule Purpose and Scope
Supports the ability of operators to comply with the operational rule requirementsPart 26 requires actions of DAHs, such as:compliance plan,design changes,instructions for continued airworthiness,distribution of information to affected operators
