Notice of proposed rulemaking (NPRM).

The FAA proposes to adopt a new airworthiness directive (AD) for all GE Honda Aero Engines (GHAE) HF120 turbofan engines with a certain fuel pump metering unit (FPMU) assembly. This proposed AD was prompted by damage found on the permanent magnetic alternator (PMA) drive gear within the FPMU assembly. This proposed AD would require removal of a certain FPMU assembly and its replacement with a part eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
