AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators of the affected American Champion Models 7 and 8 series airplanes should perform repetitive inspections of the fuselage belly as outlined in Service Letter 435 and complete the one-time tethering of the emergency door jettison pin per Service Letter 434. Additionally, installing floorboard extensions as described in Service Letter 436 is recommended to reduce loose object migration. No specific compliance deadlines are mandated, but adherence during 100-hour or annual inspections is advised.
Summary
Special Airworthiness Information Bulletin SAIB: CE-11-43 is an FAA informational bulletin addressing possible flight control interference in American Champion Aircraft Corporation Models 7EC, 7ECA, 7GCAA, 7GCBC, 7KCAB, 8KCAB, and 8GCBC airplanes. The bulletin highlights incidents where loose objects, such as emergency door jettison pins and seat belt buckle components, caused partial control jams during flight. It provides safety information and service letter references to mitigate these risks.
What changed
SAIB CE-11-43 introduces awareness of flight control interference risks due to loose objects in specific American Champion aircraft models. It references three service letters issued by American Champion that recommend tethering emergency door pins, inspecting the fuselage belly for loose items, and installing floorboard extensions to prevent object migration. This bulletin does not mandate regulatory action but advises recommended inspections and modifications.
Why it matters
This bulletin is important for aviation professionals because loose objects interfering with flight controls can lead to partial or momentary control loss, posing safety risks during critical flight phases such as aerobatics. Operators and maintenance personnel need to be aware of these potential hazards to prevent incidents and ensure continued airworthiness. Implementing the recommended inspections and modifications helps maintain safe flight control operation and reduces the risk of in-flight control jams.
