The U.S. Federal Aviation Administration (FAA) (Washington, DC) recently issued a proposal to adopt a new airworthiness directive for select aircraft models by The Boeing Co. (Chicago, Illinois).
The FAA's notice of proposed rulemaking (NPRM) applies to the 777-200, -200LR, -300, and -300ER series airplanes from Boeing.
“This proposed [directive] was prompted by reports of corrosion in the aft fuselage,” the FAA writes in its notice. “This proposed [directive] would require a one-time review of the operator's maintenance procedures, repetitive detailed internal and external inspections for corrosion or cracking, and applicable on-condition actions.”
The proposed directive would also include an optional terminating action for the inspections, the FAA explains.
The FAA is seeking comments on the proposal by August 28, 2017. For more information on the proposal, the full NPRM can be viewed here.
