Plain English Summary

1/10 complexity

What this requires: Owners of specific Beechcraft King Air aircraft must inspect the lower rudder hinge assembly — the mechanical pivot point that connects the rudder (the vertical steering surface on the tail) to the aircraft body.

Who is affected: Operators of Beechcraft models 65-90, 65-A90, and B90 with serial numbers ranging from LJ-1 to LJ-438.

What must be done:

Follow the inspection procedures outlined in Beechcraft Service Instruction No. 0170-131
Complete the inspection within 100 hours of flight time after 6 June 1969

Why it matters: This safety check prevents the rudder from becoming detached or jamming during flight, which could cause loss of directional control.
