Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to all Boeing Model 777 series airplanes. That action would have required repetitive inspections for cracking of the floor beam structure located at body station 246; and repair, if necessary. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate that the unsafe condition does not exist on the airplanes identified in the proposed rule. Accordingly, the proposed rule is withdrawn.
