What to do

Operators should inspect fuel tanks for sloshing compound deterioration following the procedures in Piper Service Bulletin 251D. They should incorporate repetitive 100-hour or annual inspections into maintenance programs for tanks treated with Randolph 802 sealer. If flaking or leaks are detected, fuel tank replacement is recommended as per the service bulletin.

Summary

Special Airworthiness Information Bulletin SAIB: CE-09-23 is an FAA informational bulletin addressing fuel starvation risks in Piper PA-28, PA-32, and PA-34 series airplanes. It highlights concerns about environmental deterioration of a sloshing compound previously used to repair leaking fuel tanks, which can peel and block fuel tank outlets, potentially starving the engine of fuel.

What changed

This bulletin introduces awareness of the potential hazard caused by the peeling of the Randolph 802 sloshing compound inside fuel tanks of affected Piper aircraft. It references Piper Service Bulletin 251D, which mandates repetitive 100-hour inspections for tanks previously treated with this sealer and recommends tank replacement if deterioration is found.

Why it matters

This information is critical for operators, maintenance personnel, and compliance teams to prevent engine power loss due to fuel starvation caused by blocked fuel tank outlets. Understanding and following the recommended inspections can help avoid forced landings and substantial aircraft damage, improving flight safety and reliability.
