Pratt & Whitney Division Engines
This AD applies to Pratt & Whitney Division JT8D-209, JT8D-217, JT8D-217A, JT8D-217C, JT8D-219, JT8D-1, JT8D-11, JT8D-15, JT8D-15A, JT8D-17, JT8D-17A, JT8D-17AR, JT8D-17R, JT8D-1A, JT8D-1B, JT8D-7, JT8D-7A, JT8D-7B, JT8D-9, JT8D-9A.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Pratt & Whitney (PW) JT8D series turbofan engines, that currently requires initial and repetitive inspections of the Number 7 fuel nozzle and support assembly, replacement of the Number 7 fuel nozzle and support assembly with a more leak-resistant configuration, and replacement of aluminum oil pressure and scavenge tube fittings with steel fittings. This amendment adds a requirement incorporated in a new revision of a PW Alert Service Bulletin (ASB) that was omitted from the existing AD to replace an additional aluminum oil scavenge line bolt with a steel bolt. This amendment also makes a correction to a note in the compliance section to apply only to PW JT8D-200 series engines. This amendment is prompted by the need to make these corrections. The actions specified by this AD are intended to prevent fuel leakage from the Number 7 fuel nozzle and support assembly, ignition of that leaking fuel, and liberation of oil from melted oil line fittings, which can result in an uncontained engine fire and damage to the aircraft.
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.
