Plain English Summary

2/10 complexity

What this requires

This directive orders a mandatory safety inspection of the landing gear torque tube on specific Beechcraft aircraft. Operators must check for damage—specifically stretched (elongated) bolt holes or evidence of previous repair attempts (double drilling)—where the nose wheel steering mechanism attaches to the tube.

Who must comply

Only owners and operators of Beechcraft Model 65-B80 aircraft with serial numbers LD-506 through LD-511 (six specific aircraft).

What must be done

The inspection must be completed within 100 flight hours (time in service) after 31 August 1979. If damage is found, the torque tube must be replaced in accordance with the referenced technical standard (Beechcraft Service Instruction No. 1049).

Why this matters

The torque tube is a structural component critical to landing gear operation. Undetected damage could lead to landing gear failure, posing serious safety risks during takeoff or landing.
