(3) Do a general visual inspection for traces of fuel coming from the EFP electrical wiring conduit outlet at the lower body fairing area for engine EFPs and at the right-hand landing light compartment for the APU EFP.
Unsafe condition
This AD was prompted by reports of fuel leaks from the electrical connectors and conduits of the engine and auxiliary power unit (APU) electrical fuel pump (EFP) cartridge/canister, and the development of additional actions to address the root cause of the fuel leaks. The FAA is issuing this AD to address the potential for a fire hazard as a result of fuel leak from the APU EFP electrical conduit in the hot landing light compartment.
Affected ADs
This AD replaces AD 2017-22-06, Amendment 39-19086 (82 FR 49498, October 26, 2017) (AD 2017-22-06).
