Federal Register / Vol. 86, No. 164 / Friday, August 27, 2021 / Proposed Rules compliance times in Part 1, paragraph 1, or Part 2, paragraph 1, of the ASB.
i If the results of the torque inspection required by paragraph g6 of this AD meet the criteria for engine removal specified in Table 1, 2 or 3, of the ASB, as applicable, perform piece-part inspections in accordance with the ICA on all 3rd-stage and 4th-stage LPT blades before exceeding 20 hours TIS
since the last torque inspection.
ii Reserved 7 The initial inspection or the reinspection interval should not be reset unless the blades are refurbished. Whenever a used blade is reinstalled in a rotor, the previous used time should be subtracted from the initial inspection threshold.
8 Whenever a refurbished or used blade is intermixed with zero hours time-since-new TSN blades in a rotor, use the lowest initial inspection threshold that is applicable.
9 At the next accessibility to the LPT-toexhaust case bolts and nuts after the effective date of this AD, do the following:
i Replace the bolts with part number P/
N MS955726 bolts;
ii Replace the nuts with P/N 375095 nuts or P/N 490270 nuts; and iii Install crushable sleeve spacers, P/N
822903, under the head of the bolts.
Note 1 to paragraph g: Guidance on replacing the 3rd-stage and 4th-stage LPT
blades can be found in P&W ASB JT8D
A6507, dated November 2, 2020.
Note 2 to paragraph g: Guidance on replacing the LPT-to-exhaust case bolts and nuts and installing the crushable sleeve spacers can be found in P&W ASB No. JT8D
A6494, Revision No. 1, dated January 26, 2010.

h Definitions For the purpose of this AD:
1 An engine shop visit is the induction of an engine into the shop for maintenance involving the separation of pairs of major mating engine flanges, except that the separation of engine flanges solely for the purposes of transportation without subsequent engine maintenance does not constitute an engine shop visit.
2 Accessibility to the LPT-to-exhaust case bolts refers to maintenance involving the inner turbine fan ducts being removed from the engine.
3 Parts eligible for installation are 3rdstage or 4th-stage LPT blades with less than 5,000 hours TIS.
4 A piece-part inspection is when the blades are removed from the rotor.
5 A used blade refers to a 3rd-stage or 4th-stage LPT blade that has more than zero hours TSN.
i Credit for Previous Actions You may take credit for any initial torque inspection for shroud notch wear required by paragraphs g1 through 3 of this AD if you performed the initial inspection before the effective date of this AD using P&W ASB No.
