Airworthiness Directive · Amendment 39-13916 · Pratt & Whitney JT8D-200 Series Turbofan Engines
Pratt & Whitney JT8D-200 Series Turbofan Engines
This AD applies to Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 turbofan engines. These engines are installed on, but not limited to, Boeing 727 series and McDonnell Douglas MD-80 series airplanes.
The FAA is superseding existing airworthiness directive (AD) 99-22-14 for Pratt & Whitney (PW) JT8D-200 series turbofan engines. That AD currently requires removing low pressure turbine (LPT)-to- exhaust case bolts and nuts and replacement with improved LPT-to- exhaust case bolts and nuts on JT8D-209, -217, -217A, -217C, and -219 engines. That AD also requires installation of improved high pressure turbine (HPT) containment hardware on JT8D-217C, and -219 engines. This AD requires installation of improved HPT containment hardware on JT8D- 209, -217, -217A, -217C, and -219 engines. This AD results from four reports of uncontained HPT failures of JT8D-200 series engines, since AD 99-22-14 was issued. We are issuing this AD to prevent uncontained HPT events resulting from HPT shaft fractures.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
(f) Install the improved HPT containment hardware. Use the applicable compliance schedule in Table 1 of this AD, and paragraphs 1. through 3.G. of the Accomplishment Instructions of PW Alert Service Bulletin (ASB) No. JT8D A6346, dated September 10, 1998, or Revision 1, dated April 23, 1999, or Revision 2, dated December 1, 1999, or Revision 3, dated May 21, 2004.
| For engine models: | Install improved HPT containment hardware: |
|---|---|
| JT8D-217C and -219 | At the next engine shop visit after the effective date of this AD, but no later than December 31, 2004. |
| JT8D-209, -217, and -217A | At the next engine shop visit after the effective date of this AD, but no later than December 31, 2007. |
For the purpose of this AD, an engine shop visit is defined as engine maintenance that involves the separation of the J and K flanges.
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.
