Airworthiness Directive · Amendment 39-17311 · Time limits
Pilatus Aircraft Ltd. Airplanes
Superseded. A later AD replaced this one: AD 2014-22-01. Comply with the one in force.
This AD applies to Pilatus Aircraft Ltd. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes, all manufacturer serial numbers (MSNs), certificated in any category.
We are superseding an existing airworthiness directive (AD) for all Pilatus Aircraft Ltd. Models PC-12, PC-12/45, PC-12/47, and PC- 12/47E airplanes. 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. The MCAI describes the unsafe condition as a need to incorporate new revisions into the Limitations section, Chapter 4, of the FAA-approved maintenance program (e.g., maintenance manual). We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) For Models PC-12 and PC-12/45 airplanes, MSNs 101 through 299: Within the next 100 hours time-in-service (TIS) after August 19, 2009 (the effective date retained from AD 2009-14-13, Amendment 39-15963 (74 FR 34213, July 15, 2009)) or 1 year after August 19, 2009 (the effective date retained from AD 2009-14-13), whichever occurs first, replace the torque tube part number (P/N) 532.50.12.047 with torque tube P/N 532.50.12.064 following PILATUS AIRCRAFT LTD. Service Bulletin No: 32-021, dated November 21, 2008.
(2) For all airplanes: As of March 26, 2013 (the effective date of this AD), do not install torque tube P/N 532.50.12.047.
(3) For all airplanes: Before further flight after March 26, 2013 (the effective date of this AD), insert Data module code 12-A-04-00-00-00A-000A-A, “STRUCTURAL, COMPONENT AND MISCELLANEOUS—AIRWORTHINESS LIMITATIONS,” dated October 15, 2012, of the Pilatus Model Identification: 12 Aircraft Maintenance Manual, PC12, PC12/45, PC 12/47 AMM Document No. 02049, 12-A-AM-00-00-00-I, revision 26, dated December 15, 2012, for Models PC-12, PC-12/45, PC-12/47, and Data module code 12-B-04-00-00-00A-000A-A, “STRUCTURAL AND COMPONENT LIMITATIONS—AIRWORTHINESS LIMITATIONS,” dated October 15, 2012, of the Pilatus Model Identification: 12 Aircraft Maintenance Manual, PC 12/47E AMM Document No. 02300, 12-B-AM-00-00-00-I, revision 9, dated December 15, 2012, for Model PC-12/47E, into the Limitations section of the FAA-approved maintenance program (e.g., maintenance manual). These limitations section revisions do the following:
(i) Establish an inspection of the wing main spar fastener holes at rib 6,
(ii) Specify replacement of components before or upon reaching the applicable life limit, and
(iii) Specify accomplishment of all applicable maintenance tasks within certain thresholds and intervals.
(4) For all airplanes: If no compliance time is specified in the documents listed in paragraph (f)(3) of this AD when doing any corrective actions where discrepancies are found as required in paragraph (f)(3)(iii) of this AD, do these corrective actions before further flight after doing the applicable maintenance task.
(5) For all airplanes: During the accomplishment of the actions required in paragraphs (f)(3)(i), (f)(3)(ii), and (f)(3)(iii) of this AD, if a discrepancy is found that is not identified in the documents listed in paragraph (f)(3) of this AD, before further flight after finding the discrepancy, contact Pilatus Aircraft Ltd. at the address specified in paragraph (i)(5) of this AD for a repair scheme and incorporate that repair scheme.
This paragraph provides credit for the actions required in paragraph (f)(3) of this AD if already done before March 6, 2013 (the effective date of this AD) following Pilatus PC12 Aircraft Maintenance Manual Temporary Revision No. 04-03, dated October 15, 2012, which transmits Unclassified 12-A/AMP-04 “STRUCTURAL, COMPONENT AND MISCELLANEOUS—AIRWORTHINESS LIMITATIONS,” document 12-A-04-00-00-00A-000A-A, dated October 15, 2012; and Pilatus PC12/47E Aircraft Maintenance Manual Temporary Revision No. 04-01, dated October 15, 2012, which transmits Unclassified 12-B/AMP-04 “STRUCTURAL AND COMPONENT LIMITATIONS—AIRWORTHINESS LIMITATIONS,” document 12-B-04-00-00-00A-000A-A, dated October 15, 2012.
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.
