EASA SIB 2007-27
WITHDRAWN: REPLACED BY EASA AD 2009-0214
Summary
EASA Safety Information Notice No. 2007-27 N is a safety communication regarding EADS SOCATA TBM 700 aircraft main landing gear wheel axles. It addresses a safety issue involving partially unscrewed wheel attaching nuts on TBM 850 aircraft, caused by machining defects in certain wheel axle production batches. This notice informs operators about the DGAC France Emergency Airworthiness Directive UF-2007-015 related to this issue.
What Changed
This notice replaces the previous AD F-2007-007 by incorporating additional affected wheel axle batch numbers and specifying a deadline for replacing the locking washer part number SKW40716-118. It clarifies that the unsafe condition arises from improperly manufactured parts rather than a design approval issue, and thus EASA issues this as safety information rather than a formal AD.
Why It Matters
The issue can lead to loss of braking and potential wheel loss, posing a serious safety risk for operators of affected TBM 700 aircraft. Maintenance and compliance teams must be aware of the affected batch numbers to ensure proper inspections and part replacements are conducted. Understanding the regulatory context helps national authorities manage the airworthiness directives effectively.
What To Do
Operators of TBM 700 aircraft with serial numbers 205, 240, 244 through 408 and affected wheel axle batch numbers should follow the DGAC France Emergency AD UF-2007-015 requirements. This includes inspecting the main landing gear wheel axle and replacing the locking washer P/N SKW40716-118 by the specified limit date. For further information, stakeholders should contact EASA's Airworthiness Directives section via ADs@easa.europa.eu.
