Airworthiness Directive · Amendment 39-10641 · Cessna Aircraft Company Model 172R Airplanes
Cessna Aircraft Company Model 172R Airplanes
Model 172R airplanes with the following serial numbers, certificated in any category: 17280004 through 17280016, 17280018 through 17280050, 17280052 through 17280058, 17280060 through 17280062, 17280064, 17280066 through 17280082, 17280085 through 17280099, 17280101 through 17280113, 17280115, 17280116, 17280118 through 17280125, 17280128 through 17280131, and 17280138.
This amendment adopts a new airworthiness directive (AD) that applies to certain Cessna Aircraft Company Model 172R airplanes. This AD requires modifying the lower forward doorpost bulkhead by installing rivets. This AD is the result of a report from the manufacturer that these rivets were erroneously omitted during manufacture of some of the new production airplanes. The actions specified by this AD are intended to prevent reduced structural rigidity at the forward doorpost bulkhead, which could result in structural cracking and possible loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
