C. Reason Objective:
To remove from service a suspect population of parts.
Condition:
The forward and aft hooks of stage 1 disks identified by the serial numbers are potentially non-conforming.HPTR Cause:
Machining and inspection on the serial numbered stage 1 disks was found to be inconsistent with the engineering drawing.HPTR Improvement:
The stage 1 disks specified by serial number in this service bulletin are to be removed from service no later than the cycle limitHPTR defined.
Substantiation:
Analysis and comparative analysis.
This service bulletin complements the changes made to the HPT Rotor - Life Limits (DMC-PASSPORT20-A-05-11-03-00A-0B1A-D) . The removal from service for the population herein within the required cycles of 05-11-03 maintains airworthiness.
D. Description The purpose of this service bulletin is to require removal from service the stage 1 disk identified by serial numbers.HPTR E. Compliance Category 1 GE recommends that you do this service bulletin before 3800 cycles.
Impact A This recommendation is to address a condition that may affect flight safety.
Note: This service bulletin can be done in the engine shop.
F. Approval The data contained in this service bulletin has been reviewed by the FAA or authorized entity representing the FAA and repair(s) and modification(s) herein comply with the applicable aviation regulations and are APPROVED for installation in the model(s) listed in this service bulletin.
G. Manpower You will need approximately one man-hour after piece-part exposure to comply with this service bulletin.
H. Weight and balance Weight and balance are not changed I. Electrical load data Not applicable.
