AD 2011-09-08 Airworthiness Directives; Pacific Aerospace Limited Model 750XL Airplanes

Makes named: pacific aerospace. Models named: 750XL. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Pacific Aerospace Limited Model 750XL airplanes, all serial numbers through 111, certificated in any category.

Unless already done, do the following actions: (1) Inspect the quadrant welds in the LH rudder pedal assembly, part number (P/N) 11-45711-1, and the RH rudder pedal assembly, P/N 11-45713-1, for cracks at the following times following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/050, Issue 1, dated December 15, 2010: (i) Initially before further flight after the effective date of this AD. (ii) Repetitively thereafter at intervals not to exceed 300 hours time-in-service (TIS) until the modification repair scheme required in paragraph (f)(2) of this AD is incorporated. (2) Incorporate modification repair scheme Pacific Aerospace Drawing Number 11-03221/22, dated December 3, 2010, as specified in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/050, Issue 1, dated December 15, 2010, at the following time: (i) Before further flight after any inspection required in paragraphs (f)(1)(i) or (f)(1)(ii) of this AD if any cracks are found. (ii) Within the next 1,200 hours TIS after the effective date of this AD or within the next 12 months after the effective date of this AD, whichever occurs first, if no cracks are found during any inspection required in paragraphs (f)(1)(i) or (f)(1)(ii) of this AD. Incorporating modification repair scheme Pacific Aerospace Drawing Number 11-03221/22, dated December 3, 2010, terminates the repetitive inspections required in paragraph (f)(1)(ii) of this AD. (3) You may incorporate modification repair scheme Pacific Aerospace Drawing Number 11-03221/22, dated December 3, 2010, at any time after the initial inspection required in paragraph (f)(1)(i) of this AD but no later than the compliance time specified in paragraph (f)(2)(ii) of this AD as long as no cracks were found. As required in paragraph (f)(2)(i) of this AD, the modification repair scheme must be incorporated before further flight if cracks are found. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: The MCAI Civil Aviation Authority (CAA) AD DCA/750XL/14, dated March 31, 2011, and the applicable service bulletin specifies repair of the rudder pedal assembly if cracks are found exceeding certain limits and allows continued flight for a specified time if cracks are found in the rudder pedal assembly that do not exceed certain limits. This AD does not allow continued flight if any crack is found. The FAA policy is to disallow airplane operation when known cracks exist in primary structure, unless the ability to sustain ultimate load with these cracks is proven. The rudder pedal assembly is considered primary structure, and the FAA has not received any analysis to prove that ultimate load can be sustained with cracks in this area. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to Attn: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number.
