Original Product - Type Certificate Number : 3A13 Make : Cessna Model : 182 E, F, G, H, J, K, L, M, N and P Description of Type Design Change:

Installation of Continental O-470-S or O-470-R engine. Data required: (1) C S Industries Installation Instructions Form 182-2 dated June 5, 1990, or later “FAA Approved” revision; (2) Cessna Single Engine Service Letter SE75-2 dated August 22, 1975; and (3) Continental Aircraft Engine Service Bulletin M75-13 dated June 20, 1975.

The Continental O-470-R or O-470-S engine may be installed interchangeably in all of the airplane models listed above. The Hartzell HC-82XF-1 or HC-A2XF-1 or BHC-A2XF-1 (with 8433-2 blade) propellers are not approved on the 0-470-R or 0-470-S engines. This approval should not be extended to other specific airplanes of these models on which other previously approved modifications are incorporated, unless it is determined that the interrelationship between this change and any of the other previously approved modifications will introduce no adverse effect upon the airworthiness of that airplane. If the holder agrees to permit another person to use this certificate to alter the product, the holder shall give the other person written evidence of that permission.
