Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to all Boeing Model 777-200 series airplanes equipped with General Electric engines. That action would have required installation of a high-temperature silicone foam seal on the aft fairing of the strut. Since issuance of the NPRM, the Federal Aviation Administration (FAA) has received new information that indicates that the unsafe condition would not be prevented by the proposed action. Subsequently, the FAA has issued new rulemaking that positively addresses the unsafe condition identified in the NPRM and eliminates the need for the actions proposed by the NPRM. Accordingly, the proposed rule is withdrawn.
