What to do
Operators of affected M7 Aerospace SA226 and SA227 airplanes should inspect the left and right ailerons using the procedures in M7 Aerospace service letters 226-SL-045, 227-SL-060, and CC7-SL-053. Any cracks found must be repaired with FAA-approved methods or the aileron replaced before further flight. Reporting any cracks to M7 Aerospace Engineering is also recommended.
Summary
The FAA Special Airworthiness Information Bulletin SAIB: CE-13-42 informs owners and operators of M7 Aerospace LLC Models SA226-T/-T(B)/-AT/-TC, SA227-TT/-AT/-AC/-BC, and SA227-CC/-DC airplanes about potential cracks in the left and right aileron spar and skins. This bulletin provides inspection procedures to detect cracks near the outboard aileron hinge fitting. The bulletin is informational and does not mandate regulatory action at this time.
What changed
This bulletin introduces new inspection procedures for the aileron spar web and adjacent skins on specified M7 Aerospace SA226 and SA227 series airplanes. It highlights limited reports of cracks and references M7 Aerospace service letters that provide detailed inspection instructions. No airworthiness directive has been issued, but the FAA recommends proactive inspections and repairs as necessary.
Why it matters
This information is important for aviation professionals because cracks in the aileron spar and skins can affect flight safety and structural integrity. Operators and maintenance organizations need to be aware of the potential issue to prevent in-flight failures. Early detection and repair help maintain airworthiness and avoid costly unscheduled maintenance or grounding.
