## Summary

This document proposes to revise an earlier proposed airworthiness directive (AD) that would supersede Airworthiness Directive (AD) 2000-23-01, which applies to all Cessna Aircraft Company (Cessna) Model 402C airplanes. AD 2000-23-01 currently requires repetitive inspections of the forward, aft, and auxiliary wing spars for cracks, and repair or replacement as necessary. Cessna has performed fatigue and crack growth analyses of the wings of these airplanes, and the Federal Aviation Administration (FAA) has evaluated this information and determined that a wing spar modification and inspections are necessary on the Model 414A airplanes as well as the Model 402C airplanes. The earlier NPRM would have required you to inspect the wing spar caps for fatigue cracks with any necessary repair or replacement and to incorporate a spar strap modification on each wing spar. We received a request to reopen the comment period for this action in order to allow more time to evaluate the impactof the actions of the proposed AD. Therefore, we are reopening the comment period to allow the public additional time to comment on the proposed AD.
