Airworthiness Directive · Amendment 39-15452 · Flight controls
PILATUS AIRCRAFT LTD. Model PC-12, PC-12/45, and PC-12/47 Airplanes
This AD applies to Models PC-12, PC-12/45, and PC-12/47 airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. This AD requires inserting changes into the airworthiness limitations of the FAA-approved maintenance program. We are issuing this AD to require actions to correct the unsafe condition on these products.
Note 1: Pilatus has implemented a new software publication system. During the implementation of this new system, the airplane maintenance manual revision number was reset to 0. For the purposes of this AD, the date of issue takes prescedence over the revision level.
(f) Unless already done, do the following within the next 30 days after May 9, 2008 (the effective date of this AD).
(1) Insert unclassified document 12-A/AMP-04, Structural, Component and Miscellaneous—Airworthiness Limitations, 12-A-04-00-00-00A-000A-A, dated October 26, 2007 (Pilatus PC-12 Airplane Maintenance Manual, Chapter 4, Report No. 02049, Issue 1, Revision 0, dated November 20, 2007), into the airworthiness limitations section of the FAA-approved maintenance program (e.g., maintenance manual) or use the CD version that incorporates the November 20, 2007, version of chapter 4 and the corresponding version of chapter 5. You may use any future amendment to this Airworthiness Limitations section provided it does not change the inspection intervals, requirements, or the life limits for the pitch trim actuator and pitch trim actuator attachment parts of the document referenced above. The owner/operator holding at least a private pilot certificate as authorized by 14 CFR 43.7 may do this action. Make an entry in the aircraft records showing compliance with this portion of the AD following 14 CFR 43.9.
(2) In order to avoid confusion with the new pitch trim actuator limitations now contained in chapter 4 (previously contained in chapter 5), make pen and ink changes in chapter 5 and line through references to limitations for the pitch trim actuator. You do not have to make these pen and ink changes if you are using the CD version that incorporates the November 20, 2007, version of chapter 4 and the corresponding version of chapter 5.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
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.
