This AD applies to the following Pratt & Whitney Canada Corp. (P&WC) turbofan engines with compressor air to HMU delivery tube, part number (P/N) 3119150-01 installed:
(1) JT15D-5 turbofan engines, serial numbers (SNs) below and including SN PCE-100411.
(2) JT15D-5 turbofan engines, SNs below and including SN PCE-JA0818.
(3) All JT15D-5B turbofan engines.
(4) All JT15D-5F turbofan engines.
(5) JT15D-5R turbofan engines SNs below and including SN PCE-JG0104.
(6) All JT15D-5 turbofan engines converted to model JT15D-5R by incorporation of P&WC Service Bulletin No. 7605.
These engines are installed on, but not limited to, Hawker Beechcraft models 400, 400A, and 400T airplanes.
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. The MCAI describes the unsafe condition as follows:
Unless already done, do the following actions.
(1) Within 200 flight hours after the effective date of this AD or within 30 days after the effective date of this AD, whichever occurs first, remove from service compressor air to HMU delivery tube, P/N 3119150-01.
(2) Install a serviceable compressor air to HMU delivery tube in accordance with P&WC Alert Service Bulletin (ASB) No. JT15D-72-A7611, Revision 1, dated June 16, 2008.
(3) After the effective date of this AD, do not install any compressor air to HMU delivery tube, P/N 3119150-01, onto any engine.
For the purpose of this AD, a serviceable compressor air to HMU delivery tube is a compressor air to HMU delivery tube that is other than the tube part number listed in this AD.
(g) Alternative Methods of Compliance (AMOCs): The Manager, Engine Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
Replacement of the compressor air to HMU delivery tube using P&WC ASB No. JT15D-72-A7611, dated March 26, 2008, before the effective date of this AD, meets the requirements of this AD.
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.
