Mandatory Service Bulletin Revision
Teledyne Continental Motors (TCM) has released Revision C of Mandatory Service Bulletin (MSB) 00-5, under which TCM will field inspect crankshafts for a positive metallurgical flaw. Revision C expands the number of crankshafts to be inspected. The inspection can be performed at your local FBO and will be covered under TCM's warranty policy as defined in MSB 00-5. To determine if you are affected by this revision of bulletin, you must know your engine serial number and/or the serial number of the replacement crankshaft if your engine was field overhauled. Owners of engines and/or crankshafts supplied during the period of April 1998 through March 2000 should use the website to determine if they are affected.

If you have previously entered the website and were affected, you can check status by using your assigned contact number. IF YOU PREVIOUSLY ENTERED THE WEB SITE AND WERE ADVISED YOU WERE NOT AFFECTED, PLEASE BE ADVISED THAT THE NEW REVISION MAY NOW CHANGE THAT STATUS. If the contact data you entered is accurate and you are in this category, TCM will attempt to contact you directly. AS A PRECAUTION, IT IS STRONGLY SUGGESTED THAT YOU RECHECK THE STATUS OF YOUR CRANKSHAFT USING THE LATEST REVISION THAT INCLUDES MORE CRANKSHAFT SERIAL NUMBERS.
