EASA SIB CE-13-41
M7 Aerospace (formerly Fairchild, Swearingen) SA226 and SA227 Aeroplanes - Main and Nose Landing Gear Actuators
Summary
The Special Airworthiness Information Bulletin SAIB: CE-13-41 is an FAA informational bulletin addressing landing gear actuator concerns on M7 Aerospace SA226 and SA227 series airplanes. It specifically covers Bertea (Parker-Bertea, Parker-Hannifin) main and nose landing gear actuators with part numbers 235600-( ), 27-51016, and 27-52010. The bulletin provides inspection and repair guidelines but does not mandate regulatory action.
What Changed
This bulletin introduces new inspection and repair procedures for the fixed actuator body lug of certain Bertea main and nose landing gear actuators on specified M7 Aerospace SA226 and SA227 models. It references M7 Aerospace Service Bulletins 226-32-077 R1, 227-32-053 R1, and CC7-32-019 R1 for detailed instructions. No airworthiness directive has been issued at this time.
Why It Matters
This information is important for operators and maintenance organizations to prevent potential landing gear actuator failures caused by cracks in the actuator body lug. Early detection and repair or replacement of affected actuators enhance aircraft safety and reduce the risk of in-service malfunctions. Compliance with the recommended inspections supports continued airworthiness without mandatory regulatory enforcement.
What To Do
Operators of affected M7 Aerospace SA226 and SA227 series airplanes should inspect Bertea main and nose landing gear actuators using the procedures and intervals outlined in the referenced M7 Aerospace Service Bulletins. Any actuator found cracked beyond repair limits must be repaired or replaced before further flight. There is no mandatory compliance deadline, but timely action is recommended to maintain safety.
