Summary
The FAA is revising an earlier notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2012-07-06. AD 2012- 07-06 applies to certain The Boeing Company Model 777-200, -200LR, - 300, -300ER, and 777F series airplanes. This action revises the NPRM by proposing to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
