What to do
Owners and operators should review and comply with all airspeed and maneuvering limitations for their modified aircraft and conduct a one-time detailed inspection of the wings from Wing Station 23 to the wing tip within the next 100 hours time-in-service. The inspection should focus on specific areas such as wrinkles, cracks, loose fasteners, and signs of distress as outlined in the bulletin. Any damage found should be reported to the FAA Atlanta Aircraft Certification Office with detailed information and photographs if possible.
Summary
The Cessna Aircraft Company 336, 337 and (Reims) F337 aeroplanes - Wingtip Extensions Special Airworthiness Information Bulletin (SAIB: CE-10-20 R1) is an FAA advisory bulletin addressing safety concerns related to wingtip extensions on Cessna Models 336, 337, and F337 (Reims) series airplanes. It highlights potential structural issues such as wrinkled skins, cracks, and loose wing tips following modifications with Supplemental Type Certificates (STCs) for extended wingtips and winglets. The bulletin provides guidance to enhance safety but does not mandate regulatory action.
What changed
This revision of SAIB CE-10-20 corrects a typographical error, expands the list of potentially affected aircraft models, and adds additional focused inspection items. It reflects feedback from individuals and other airworthiness authorities and updates inspection recommendations to address ongoing safety concerns identified after a fatal accident involving a Cessna Model T337G with wingtip modifications.
Why it matters
This SAIB matters to aviation professionals because it raises awareness of possible structural integrity issues in modified Cessna 336, 337, and F337 aircraft, which could impact flight safety. Operators and maintenance personnel must be vigilant for signs of damage or deterioration in wingtip extensions to prevent accidents. The bulletin provides practical inspection guidance to identify and address potential problems before they compromise airworthiness.
