EASA SIB CE-15-05R1
M7 Aerospace (Fairchild, Swearingen) SA226 and SA227 Aeroplanes - Aileron Control System
Summary
The Special Airworthiness Information Bulletin SAIB: CE-15-05R1 is an FAA informational bulletin addressing the aileron control system on M7 Aerospace LLC Models SA226 and SA227 series airplanes, including SA226-T/-T(B)/-AT/-TC, SA227-TT/-AT/-AC/-BC, and SA227-CC/-DC. It provides enhanced inspection and maintenance recommendations for the left-hand and right-hand aileron control systems to ensure continued airworthiness. This bulletin is not mandatory and does not impose regulatory requirements.
What Changed
This revision of SAIB CE-15-05 corrects a previously incorrect reference to Service Bulletin 226-27-078, updating it to the correct Service Bulletin 226-27-076. It reinforces inspection procedures for aileron control system components and recommends concurrent compliance with related service bulletins addressing rod end bearing friction checks.
Why It Matters
This bulletin is important for aviation professionals because it highlights a reported failure of a left-hand aileron rod end, which could affect flight control safety. Operators and maintenance personnel benefit from enhanced inspection guidance to detect wear or damage early, helping to maintain safe flight control operations and prevent potential control system failures.
What To Do
Owners and operators of the affected M7 Aerospace SA226 and SA227 airplanes should follow the inspection and maintenance procedures outlined in the referenced service bulletins 226-27-076, 227-27-056, CC7-27-028, and the associated bulletins addressing rod end bearing friction. These procedures should be incorporated alongside existing maintenance manual requirements during routine inspections. No specific compliance deadline is mandated.
