Summary
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), which would have applied to certain The Boeing Company Model 737-700, -800, and -900ER series airplanes. The NPRM would have required repetitive inspections to detect cracking in the crown skin panel assembly. The NPRM would also have provided optional terminating action for the repetitive inspections. Since the NPRM was issued, all affected airplanes worldwide have had applicable terminating actions accomplished, and one airplane was mistakenly included in the applicability. Accordingly, the NPRM is withdrawn.
