This Special Airworthiness Information Bulletin (SAIB) alerts you, an owner or operator, of certain Piper Models PA-46-310P, PA-46-350P, PA-46R-350T, and PA-46-500TP airplanes, of an airworthiness concern, specifically possible cracks in the engine mount where both the nose landing gear (NLG) trunnion and the NLG actuator attach. This condition is addressed in Piper Service Bulletins (SB) 1103 and 1154 and Piper Service Letter (SL) 1001. This SAIB emphasizes the importance of compliance with Piper service information.
Note: The information provided below is for reference only. See the latest version of the Piper service information for current information. Also, this SAIB does not address PA-46-310P and PA-46-350P aircraft modified by STC ST00541SE, conversion from piston to turboprop propulsion.
At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.
This revision to this SAIB provides:
• updated service information;
• a revised recommendation to incorporate a new engine mount that relieves the repetitive inspections;
• a change to the point of contact information; and
• other changes that address format and editorial content.
