BWP N/A Page 1 of 17 SPECIAL INSTRUCTION NO. 149F-23 August 04, 2023
PW1100G-JM/PW1400G-JM HPT HUB TIME OF FLIGHT REMOVAL FOR AUSI
APPLICATION:
For PW1100G-JM & PW1400G-JM engine serial numbers which contain High Pressure Turbine (HPT) hub serial numbers in this document as directed by Customer Technical Support.
THE REASON FOR THIS SPECIAL:
Review of production records identified a limited number of HPT stage 1 and stage 2 hubs which, based on Time of Flight (TOF) records review, are required to be scanned using angle ultrasonic scan inspection (AUSI) to determine serviceability as prescribed in this SI.
APPROVAL:
The part number changes and/or part changes specified in this Special Instruction obey the applicable Federal Aviation Regulations and are FAA-Approved for the engine model(s) given.
SPECIAL INSTRUCTION NO. 149F-23 -2- Pratt & Whitney Proprietary Information – ECCN EAR 99 Use or disclosure of the data contained in this sheet is subject to the restriction on the title page of this document.
DESCRIPTION:
The purpose of this Special Instruction (SI) is to remove affected HPT stage 1 and stage 2 hub part numbers identified with serial numbers listed in this document and perform AUSI per Service Bulletin 72-00-0188. HPT stage 1 and stage 2 hubs that pass the AUSI are approved for continued service operation.
COMPLIANCE CATEGORY:
On-wing Engines: Remove engines from service containing HPT stage 1 and 2 hubs with serial numbers listed in Table 1, no later than September 15th, 2023 and perform AUSI prior to return to service.
NOTE: Serviceable engines removed per this SI should be tagged as serviceable Off-wing Engines: Remove affected HPT stage 1 and 2 hubs with serial numbers listed in Table 2 and perform AUSI prior to return to service.

ACCOMPLISHMENT INSTRUCTIONS:
I. REMOVE AFFECTED PARTS FOR AUSI PER SERVICE BULLETIN 72-00-0188 NOTE: On-wing / off-wing status is per data available to P&W at the time of this SI release. Reference both Tables to determine applicability and perform action consistent with engine’s actual current status.
a. On-wing engines: Remove from service no later than September 15th, 2023 any engine containing HPT stage 1 and/or stage 2 hub serial numbers listed in Table 1. Listed Engine Serial Number (ESN) is last known ESN according to data available to P&W.
NOTE: P&W recommends first confirming the part serial number is installed in ESN
i. Inform P&W CTS when an engine containing any of the hub serial numbers listed in Table 1 (or otherwise in service) is removed from service via Field Service Representative and/or through EagleNet case entitled ‘149F-23 ESN XXXXXX Removal’.
ii. Induct removed engine for shop visit to remove and perform AUSI per Service Bulletin 72- 00-0188 on the HPT stage 1 and stage 2 hubs as listed in Table 1.
b. Off-wing engines: Induct removed engine for shop visit to remove and perform AUSI per Service Bulletin 72-00-0188 on the HPT stage 1 and stage 2 hubs as listed in Table 2 prior to returning the engine to service. Listed Engine Serial Number (ESN) is last known ESN according to data available to P&W.
c. Parts not assigned to specific ESN’s: Perform AUSI per Service Bulletin 72-00-0188 on the HPT stage 1 and stage 2 hubs as listed in Table 3 prior to installation in an engine.
NOTE FOR THE AFFECTED PART: Affected part may be replaced with a part eligible for service use.
A part eligible for service use is one that meets either requirement a or b below:
a. has passed its applicable inspection per SB 72-00-0188 [Reference 6] OR
b. is not applicable to SB 72-00-0188 [Reference 6] MATERIAL INFORMATION:
