S u m m a r y The purpose of this Service Bulletin is to introduce a new High Pressure Compressor (HPC) rear drum rotor assembly and new 14th and 15th stage HPC blade locks.
Cracks are found in the loading and locking slots of the HPC rear drum rotor assembly .
The root cause of these cracks is Thermal Mechanical Fatigue (TMF).
The new drum rotor assembly and the new seals introduced by Reference 28, Service Bulletin PW4ENG-72-816 will prevent the causes of TMF .

N O T E :
The engine serial number ef fectivity data and its related engine model identification contained in this Service Bulletin are taken from the records of part(s) incorporation during initial manufacture.
After initial engine manufacture, but before final delivery , P&W may change part(s) in the engine or change the model identification of the engine.
Such action is recorded on F AA337 forms.
T o find Service Bulletin PW4ENG 72-817 models that are applicable, the owner/operator of the engine must compare the Service Bulletin List supplied with the engine as sent from P&W and the List of Changes incorporated at the Airframer from F AA337 forms to the Service Bulletin PW4ENG 72-817 Ef fectivity section.

1.
Problem:
More than 200 HPC rear drum rotor assemblies from PW4000-94 and PW4000-100 engine models were reported to have cracks in the blade loading and locking slots.
2.
Cause:
The root cause is determined to be TMF .
The TMF cracks are the result of thermal gradients and related high stresses in the rear of the HPC section.
The high stresses are attributed to both the part geometry and shot peening.
The loading and locking slot part geometry has structural features that when subjected to high thermal gradients, high stress zones are created.
Shot peening adds a residual compressive stress which protects against low cycle fatigue conditions, however shot peening can be a detriment and initiate TMF .
3.
Solution:
Provide a new HPC rear drum rotor assembly .
The new rear drum rotor assembly has a dif ferent loading and locking slot geometry and incorporates the new shot peen specification introduced in Reference 28, Service Bulletin PW4ENG-72-816.
The new drum rotor assembly is less susceptible to subsequent TMF .
Also, Reference 28, Service Bulletin PW4ENG-72-816 introduced new seals to reduce thermal gradients in the rear of the HPC section.
New blade locks are necessary to fit the dif ferent loading and locking slot design.
D e s c r i p t i o n Replace the HPC rear drum rotor assembly , 13th, 14th and 15th stage blades and blade locks.
C o m p l i a n c e Category 8 Do when the operator thinks that the change is necessary because of experience with the parts being replaced.
A p p r o v a l D a t a The part number changes and/or part changes specified in the Material Information section and Accomplishment Instructions of this Service Bulletin agree with the applicable Federal A viation Regulations and are F AA-Approved for the engine model(s) given.
M a n p o w e r No more man-hours are necessary when done at complete disassembly/assembly .
