M7 Aerospace (formerly Fairchild, Swearingen) SA226 and SA227 aeroplanes - Elevator Control System
Summary
M7 Aerospace (formerly Fairchild, Swwearingen) SA226 and SA227 aeroplanes - Elevator Control System is a Special Airworthiness Information Bulletin (SAIB CE-12-08) issued by the FAA. It addresses corrosion concerns in the pitch trim actuator fuselage fittings, part number 27-43060, on M7 Aerospace Models LP SA226 and SA227 series airplanes. The bulletin provides inspection and repair recommendations but does not mandate regulatory action.
What Changed
This SAIB introduces new inspection procedures and repair or replacement instructions for the left and right hand pitch trim actuator fuselage fittings on affected M7 Aerospace SA226 and SA227 aircraft. It references specific service bulletins issued by M7 Aerospace for conducting inspections within specified timeframes and outlines corrective actions if corrosion is found.
Why It Matters
The corrosion issue in pitch trim actuator fuselage fittings can affect flight control safety if left unaddressed. Operators, maintenance organizations, and compliance teams need to be aware of the potential for corrosion and follow recommended inspection and repair procedures to maintain airworthiness and prevent possible control system failures.
What To Do
Operators of M7 Aerospace SA226 and SA227 airplanes should inspect pitch trim actuator fuselage fittings, part number 27-43060, according to the intervals and procedures in M7 Aerospace Service Bulletins 226-27-073, 227-27-053, and CC7-27-024. Inspections must occur by the next scheduled Letter D Check Inspection, not to exceed 200 flight hours, or within 2 calendar months from the service bulletin date, whichever is first. Any corroded fittings must be repaired or replaced before further flight.
