AI RBUS requests FAA to reconsider the phrases of the AD text for better clarity and understanding of operators. For example, in the paragraph (h) and (k) of the AD the phrase “I f a GEN is selected OFF by the flightcrew in accordance with the TR...” could be used instead of the current phrase “I f an I DG is shut down by the flight crew in accordance with the TR...”.

______ The FAA int ent for the Integrated Drive Generator (IDG) is sy nony mous with Generator (GEN). The AD paragraph (h) has been carried over from the previous AD 2004 - 15 - 14 and the paragraph (k) was based on the intent that the operators understand that the intent of IDG s hut down is to shut down GEN as required by the AFM. The FAA AD will be revised to clarify this intent. The FAA AD 2011 - 19 - 01 did not carried the terminating action from AD 2004 - 15 - 14 due to reasons stated in EASA AD 2011 - 0142. The FAA issued an Alternat e Means of Compliance (AMOC) for the US operators that provides instructions for inspection, repair and replacement of ID G harness and connector. Non US registered operators are advised to contact their civil aviation authority

for further disposition. Sanjay Ralhan
