AD: Pratt & Whitney

AD NUMBER: 2004-26-04
MANUFACTURER: Pratt & Whitney (Correction)
SUBJECT: Airworthiness Directive 2004-26-04
SUMMARY: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.
