## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all deHavilland Inc. (deHavilland) Models DHC- 2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes. The proposed AD would require repetitively inspecting the rear fuselage bulkhead at Station 228 for cracks. The proposed AD would also require repairing any crack found or replacing any cracked rear fuselage bulkhead in accordance with a repair or replacement scheme obtained from the manufacturer through the Federal Aviation Administration (FAA). The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Canada. The actions specified by the proposed AD are intended to detect and correct cracking of the rear fuselage bulkhead at Station 228, which could result in structural damage of the fuselage to the point of failure with consequent loss of airplane control.
