Airworthiness Directives; Aerospatiale Model ATR-42 and ATR-72 Series Airplanes

Краткое содержание

This document proposes to rescind an existing airworthiness directive (AD), applicable to all Aerospatiale Model ATR-42 and ATR-72 series airplanes, that currently requires revising the Airplane Flight Manual (AFM) 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. Since the issuance of that AD, the FAA has received further information indicating that the incident that prompted that AD was an isolated case.
