Summary
This document withdraws two notices of proposed rulemaking (NPRMs) that would have applied to Cessna Aircraft Company (Cessna) Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, and 414A airplanes. The proposed ADs would have superseded existing ADs and would have required you to repetitively inspect the wing spar caps of all airplanes for fatigue cracks and repair or replace as necessary and incorporate a spar strap modification on each wing spar on certain airplanes. The FAA has decided not to issue the new ADs as proposed. We will propose ADs after alternative solutions are developed.
