Unsafe Condition
Failure of the oleo tube reinforcement could result in structural failure of the oleo tube at the piston end, leading to loss of aircraft control.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Reinforce the oleo tubes at the piston end by installing sleeve Fairchild part SK-1636. The sleeve may be attached using two AN 435-5-4 rivets or by welding through four 5/16-inch holes drilled in the piston tube. Replace all damaged parts.
