SPECIAL NOTICE REGARDING

SAIB NE-20-05

The FAA recently issued SAIB NE-20-05, based upon a Continental Service Bulletin SB 05-8, requiring inspection and potential replacement of the camshaft gear in Continental 470, 520, and 550 engines. This notice is to answer your questions about this SAIB.

This SAIB is not an AD, but if your airplane is maintained to Part 135 standards, or if you want to have the inspection done or have the camshaft gear replaced, we can do that for you.

It is not inexpensive to replace the gear, but it is not terribly burdensome to inspect it. It takes approximately 8 hours to perform the inspection, and it should be done at each annual inspection. If the gear needs to be replaced, we would need to remove the engine (about $3500), and have the case modified by an engine shop which would also replace the gear (about $9500). This gear replacement would terminate the need for further inspections of the gear. Please let us know if you would like us to perform this service for you
