EASA SIB CE-16-06: M7 Aerospace (formerly Fairchild, Swearingen) SA26, SA226 and SA227 Aeroplanes — Rudder Control System

What to do

Operators of M7 Aerospace SA26, SA226, and SA227 airplanes should inspect the rudder bellcrank regularly and after any rudder hard-over event using the procedures in the referenced M7 Aerospace service bulletins. Any cracked bellcrank must be replaced promptly according to the service bulletin instructions. There are no specific compliance deadlines stated, but adherence to the recommended inspection intervals is advised.

Summary

The Special Airworthiness Information Bulletin SAIB: CE-16-06 is an FAA informational bulletin addressing the rudder control system on M7 Aerospace LLC Models SA26-T/-AT, SA226-T/-T(B)/-AT/-TC, SA227-TT/-AT/-AC/-BC, and SA227-CC/-DC airplanes. It provides guidance on inspecting and maintaining the rudder bellcrank, a component made from magnesium or aluminum casting, to ensure continued airworthiness. This bulletin is not a mandatory directive but offers important safety information for these aircraft models.

What changed

This bulletin introduces inspection procedures and maintenance actions for the rudder bellcrank on the affected M7 Aerospace SA26, SA226, and SA227 series airplanes. It follows service bulletins issued by M7 Aerospace after a reported fracture caused by high ground wind gust overload. The FAA recommends following these service bulletins for repetitive inspections and replacement of cracked rudder bellcranks, but no airworthiness directive has been issued.

Why it matters

This information is critical for operators and maintenance organizations to prevent potential rudder control failures due to bellcrank fractures. Early detection and replacement of cracked rudder bellcranks can enhance flight safety and reduce the risk of control system malfunctions. Compliance teams should be aware that while this bulletin is not mandatory, following its recommendations supports proactive safety management.
