Plain English Summary

2/10 complexity

What this does: This is a mandatory safety directive for owners and operators of specific Piper Twin Comanche aircraft (models PA-30 and PA-39 with serial numbers 30-1 to 30-2000 and 39-1 to 39-155).

What you must do: Install a warning placard in the cockpit that alerts pilots about the dangers of "uncoordinated manoeuvres" (flying while the aircraft is banking or yawing improperly, which can cause a dangerous stall or spin in these models). The installation must follow the technical instructions in Piper Service Bulletin No. 456A.

When: You must complete this work within 100 hours of flight time after 31 July 1975.

Why it matters: This prevents accidents caused by pilots inadvertently stalling the aircraft during uncoordinated flight, which was a known risk for these particular Twin Comanche models.
