Summary
This document withdraws a notice of proposed rulemaking (NPRM) that would have applied to all Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA-18 and PA-19 airplanes. The proposed airworthiness directive (AD) would have required either moving all toggle-style magneto switches located on the left cabin panel, adjacent to the front seat, away from this position; or replacing these switches with FAA-approved, non-keyed, rotary-style switches. 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.
