2007-21-11 Pilatus Aircraft Limited: Amendment 39-15229; Docket No. FAA-2007-29217; Directorate Identifier 2007-CE-075-AD. Effective Date (a) This airworthiness directive (AD) becomes effective November 5, 2007. Affected ADs (b) This AD supersedes AD 2000-21-14, Amendment 39-11946. Applicability (c) This AD applies to Models PC-12, PC-12/45, and PC-12-47 airplanes, all serial numbers, that are: (1) Equipped with oil pipe/hose assemblies part number (P/N) 577.11.12.104, 577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 946.37.74.308, or 946.37.74.311; and (2) certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 71: Power Plant-General. Reason (e) The mandatory continuing airworthiness information (MCAI) states: This Airworthiness Directive (AD) is prompted by occurrences where abrasive damage (chafing) has been found on oil pipe assemblies in the area of the torque oil pressure transducer on the engines of some PC-12 aircraft. Incorrect assembly after maintenance tasks can decrease distances between various pipe/hoses assemblies and adjacent components. Damaged pipes can cause oil leakages in the area of the engine. For the reasons stated above, this AD requires an inspection for damage, replacement when damage is found, and eventual replacement of all the affected pipe/hose assemblies. Actions and Compliance (f) Unless already done, do the following actions: (1)Within the next 10 hours time-in-service after November 5, 2007 (the effective date of this AD), do a configuration check and inspection of the pipe/hose assemblies for abrasive damage (chafing) and distortion following paragraph 3.B of Pilatus Aircraft Ltd. Pilatus PC12 Service Bulletin No: 71-007, dated August 21, 2007. (2) If during the configuration check and inspection required by paragraph (f)(1) of this AD any abrasive damage (chafing) on oil pipe/hose assemblies is found, before further flight, replace the hose/pipe assemblies following paragraphs 3.B, 3.C, and 3.E of Pilatus Aircraft Ltd. Pilatus PC12 Service Bulletin No: 71-007, dated August 21, 2007. (3) If during the configuration check and inspection required by paragraph (f)(1) of this AD no damage on oil pipe/hose assemblies is found, within 6 calendar months after November 5, 2007 (the effective date of this AD), replace the hose/pipe assemblies following paragraph 3.B, 3.C, and 3.E of Pilatus Aircraft Ltd. Pilatus PC12 Service Bulletin No: 71-007, dated August 21, 2007. (4) After November 5, 2007, do not install any oil pipe/hose assembly with P/N 577.11.12.104, 577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 946.37.74.308, or 946.37.74.311 on any Models PC-12, PC-12/45, or PC-12/47 airplanes. (5) After November 5, 2007, do not install a spare engine on any Models PC-12, PC-12/45, or PC-12/47 airplanes, unless it has been verified that no oil pipe/hose assembly withP/N 577.11.12.104, 577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 946.37.74.308, or 946.37.74.311 are installed on that engine. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: The MCAI allows for the temporary replacement (up to 6 months) of the hose/pipe assemblies with the same type that incorporate the potential unsafe condition (P/N 577.11.12.104, 577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 946.37.74.308, or 946.37.74.311). Due to the urgency of this unsafe condition, the FAA is mandating replacement with the improved parts immediately if damage is found. 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.

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.
