Plain English Summary

2/10 complexity

This mandatory Airworthiness Directive requires owners/operators of De Havilland DHC‑6 Twin Otters (serials 2–213, excluding 30, 58, 96, 148, 206, 208, 210, 212) to modify the propeller/power-lever interlock to prevent inadvertent feathering.

Work must follow De Havilland Service Bulletin No. 6/183 Revision B and be completed within 100 flight hours after 23 December 1969 to eliminate the risk of sudden loss of thrust and potential loss of control.
