## Summary

This document withdraws a notice of proposed rulemaking (NPRM) that would have applied to all Cessna Aircraft Company (Cessna) Models 425 and 441 airplanes. The proposed AD would have required you to revise the Airplane Flight Manual (AFM) to include requirements for activation of the airframe pneumatic deicing boots. The proposed AD was the result of reports of in-flight incidents and an accident (on airplanes other than the referenced Cessna airplanes) that occurred in icing conditions where the airframe pneumatic deicing boots were not activated. Cessna has demonstrated that the design of the affected airplanes, including the language currently in the AFM, is adequate to address the conditions identified in the proposed AD for these airplanes. Therefore, AD action is not necessary to address the conditions on these airplanes and we are withdrawing the NPRM.
