2005-17-16: Critical life-limited rotating parts

2005-17-16 Pratt & Whitney: Amendment 39-14237. Docket No. FAA-2004- 19929; Directorate Identifier 2004-NE-15-AD. Effective Date (a) This airworthiness directive (AD) becomes effective September 30, 2005. Affected ADs (b) None. Applicability (c) This AD applies to Pratt & Whitney (PW) JT8D-1, -1A, -1B, - 7, -7A, -7B, -9, -9A, -11, -15, -15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and -219 turbofan engines. These engines are installed on, but not limited to, Boeing 727 and 737 series, and McDonnell Douglas DC-9 series and MD-80 series airplanes. Unsafe Condition (d) This AD results from reports that certain JT8D critical life-limited rotating parts have been returned to service with cracks, corrosion pitting, or dimensions outside of manual limits. We are issuing this AD to prevent failure of critical life-limited rotating engine parts, which could result in an uncontained engine failure and damage to the airplane. Compliance (e)You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Inspect Parts (f) Remove all coating from the disks and hubs identified in Tables 1 and 2 of this AD and visually, dimensionally, and nondestructively inspect the parts using the inspection criteria listed in the Accomplishment Instructions portion of PW Alert Service Bulletin (ASB) No. JT8D A6442, dated April 4, 2003: (1) At the next shop visit after the effective date of this AD, but no later than March 31, 2008, for all parts listed in Table 1, and, (2) At next part accessibility for all parts listed in Table 2.
