Airworthiness Directive 00-29378
one-timeAirworthiness Directives; Aerospatiale Model ATR-42 and ATR-72 Series Airplanes
What this AD requires
This amendment rescinds an existing Airworthiness Directive (AD), applicable to all Aerospatiale Model ATR-42 and ATR-72 series airplanes. That AD currently requires revising the Airplane Flight Manual to add specific flightcrew instructions to be followed in the event of failure of the first generator, which could lead to the loss of main battery power and result in the loss of all electrical power, except the emergency battery supply, during flight. The requirements of that AD were intended to prevent failure of the second of two direct current generators after the failure of the first generator. Since the issuance of that AD, the FAA has received further information indicating that the incident that prompted that AD was an isolated case.
Which aircraft AD 00-29378 applies to
applicability derived from the AD summary — confirm the model/serial from the records
Whether AD 00-29378 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
