Any corrosion damage found should be reported via a Service Difficulty Report and repaired or replaced as necessary.
Summary
The Special Airworthiness Information Bulletin FAA SAIB CE-11-10 is an informational bulletin addressing potential corrosion issues on flap hinges, brackets, and ribs of Piper Aircraft models PA-28, PA-32, PA-34, and PA-44. It highlights corrosion found on specific parts including hinges (part numbers 62324-xx), ribs (62328-xx), and brackets (62323-00 and 65899-00). The bulletin provides guidance to operators to focus on inspections outlined in the aircraft service manuals to mitigate corrosion risks.
What changed
This bulletin introduces awareness of corrosion concerns on flap components of Piper PA-28, PA-32, PA-34, and PA-44 aircraft based on service data and maintenance findings. It does not mandate regulatory action but recommends enhanced inspection practices, especially for older aircraft or those exposed to harsh environments. No airworthiness directive or mandatory compliance is introduced at this time.
Why it matters
Corrosion on flap hinges, brackets, and ribs can compromise structural integrity and potentially lead to flap failure, impacting flight safety. Aviation professionals, including operators and maintenance organizations, need to be vigilant in inspecting these components to prevent corrosion-related issues. Early detection and corrective action help maintain aircraft airworthiness and avoid costly repairs or safety incidents.
