Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2024-21211

The FAA is revising a notice of proposed rulemaking (NPRM) that would apply to all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This action revises the NPRM by changing certain proposed actions from ultrasonic inspections (UT) to open hole high frequency eddy current (HFEC) inspections. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over that in the NPRM, the FAA is requesting comments on this SNPRM.
