ARSA, A4A Remind FAA It's Never Defined "Engine Influencing Parts"
On Oct. 14, ARSA and Airlines for America jointly requested the withdrawal of FAA Policy Memorandum AIR100-16-160-PM09 because it erroneously relied on Advisory Circular 33.70-1 to define "engine influencing parts." The memo was subsequently withdrawn, and although the reason was not immediately specified by the agency, its timing suggests the associations' letter was effective.
