Airframe Life Limitation




Cessna 441 Models, all serial numbers.


1.    Retire Airframe from service before exceeding 22,500 hours time in service; or

2.    Adopt a CASA Approved inspection program to allow operation beyond 22,500 hours time in service.

Note 1:  Substantial modification to the airframe may be required before an appropriate inspection program is approved by the Authority.

Note 2:  In developing an inspection program consideration must be given to the principles of damage tolerance.  A damage tolerant analysis of critical sites is required such that inspections include probable locations of damage due to fatigue, corrosion or accidental damage per FAR 23.573(b).  For guidance on this aspect refer to FAA Advisory Circular 23-13A “Fatigue, Failsafe and Damage Tolerance Evaluation of Metallic Structure for Normal, Utility, Aerobatic and Commuter Category Airplanes”.




This Airworthiness Directive becomes effective on 30 January 2013.


Cessna have published a limit of validity to Supplemental Inspections. Operation beyond the limit of validity requires fatigue life justification.
