Plain English Summary

3/10 complexity

This AD requires owners/operators of Cessna 500 and 501 aeroplanes (unit nos. -0001 to -0689) with thrust reversers to modify the thrust-reverser throttle load limiter per Cessna SB 500-78-11, to be completed within 150 hours TIS after 24 June 1993. The change—at owner/operator expense—addresses an incident where limiter displacement during reverser transition severely reduced engine power control.
