Cessna Aircraft - Comments

The engines noted in the Pratt and Whitney Service Bulletin, Transport Canada AD, and the draft FAA AD (JT15D-5; -5B; -5F; and -5R) are not installed on any Cessna products (excluding the -5 used on the T-47?s which should not be an issue). Therefore Cessna Engineering recommends that all references to Cessna aircraft be removed from the AD. The issue noted in the AD has been reviewed by Cessna Engineering and found not to be applicable to Cessna products with JT15D installations. Included are the PWC SB, TC AD, and Cessna letter addressing applicability for your reference.
