Summary
This document withdraws a notice of proposed rulemaking (NPRM) that would have applied to certain Piper Aircraft, Inc. Models PA-28- 140, PA-28-150, PA-28-160, PA-28-180, PA-28R-180, and PA-28R-200 airplanes. The proposed airworthiness directive (AD) would have superseded AD 71-21-08, Amendment 39-1312, which currently requires replacement of the fuel selector valve cover. This proposed AD would have added additional airplanes to the AD's applicability section and changed the compliance time of the required actions. Since issuance of the NPRM, the FAA has re-evaluated this airworthiness concern and determined that an unsafe condition does not exist that would warrant AD action. This withdrawal does not prevent the FAA from initiating future rulemaking on this subject.
