Unsafe condition
This AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that ram air turbine (RAT) forward fittings were possibly manufactured with an incorrect titanium alloy material. The FAA is issuing this AD to address RAT forward fittings that were possibly manufactured with the incorrect titanium alloy material. The unsafe condition, if not addressed, could result in loss of backup hydraulic and/or electrical power as well as the RAT module departing from the airplane.
Affected ADs
None.
