SERVICE BULLETIN CFE738

1. Planning Information A. Effectivity

(1) This is a CATEGORY 1, SAFETY service bulletin.

NOTE: Category 1 service bulletins address safety issues, typically require urgent action and are often, but not always, referred to by FAA Airworthiness Directives. Category 1 bulletins may be labeled ALERT when immediate attention is required. ALERT service bulletins are printed on light blue paper.

Category 1 bulletins will have variable compliance time which will be specific to the individual issue.

(2) This service bulletin is applicable to the CFE738-1-1B engines that have installed the stage 1 HPT rotor disk PN 5127T27P01 and stage 2 HPT rotor disk PN 5127T28P01, with serial numbers listed in Table 2 and Table 3, respectively.

B. Concurrent Requirements

(1) Not applicable.

C. Reason WARNING: FAILURE TO OBEY THIS SERVICE BULLETIN COULD CAUSE DISTRESS OF THE HPT ROTOR ASSEMBLY STAGE 1 AND STAGE 2 DISKS. IF LEFT

UNCORRECTED, THIS DISTRESS COULD CAUSE A MALFUNCTION IN A

WAY THAT LEADS TO STRUCTURAL FAILURE AND COULD CAUSE

SERIOUS INJURY OR DEATH TO PERSONNEL, AND DAMAGE TO OR LOSS OF THE AIRCRAFT.

(1) Problem:

(a) Components made from nonconforming material do not meet certification life limits and need to be removed from service.

(2) Background:

(a) Material quality investigation revealed iron contamination in the material, from which the CFE738 HPT disks stage 1 and stage 2 are made. There were no field events associated with the discovered non-conformance.

(b) Once the non-conforming material was discovered, CFE Company notified the FAA and then conducted both engineering and risk assessments to determine corrective action(s). The risk assessments indicated a safety concern due to reduced part cycle life, and replacement of the affected stage 1 HPT and stage 2 HPT found in Table 2 or Table 3 during the next major periodic inspection (MPI), core zone inspection (CZI) or access to the part for cause is recommended.

(3) Technical Validation:

(a) Substantiation is by analysis.

(4) Benefits:

(a) Nonconforming components will be removed from service.

SERVICE BULLETIN CFE738

(5) Action:

(a) This service bulletin requires that operators review their individual engine records to determine if stage 1 HPT rotor disk PN 5127T27P01 and stage 2 HPT rotor disk PN 5127T28P01 with an affected serial number listed in Table 2 or Table 3, is installed.

(b) If an affected stage 1 HPT and/or stage 2 HPT rotor disk serial number identified in Table 2 or Table 3 is installed, then replacement of stage 1 HPT rotor disk PN 5127T27P01 and/or stage 2 HPT rotor disk PN 5127T28P01, at the next MPI, CZI, or access to the part for cause is recommended.

D. Description

(1) This service bulletin provides instructions for the removal and replacement of affected stage 1 HPT rotor disk PN 5127T27P01 and stage 2 HPT rotor disk PN 5127T28P01, with serial numbers listed in Table 2 and Table 3, respectively.

E. Compliance

(1) Compliance addresses a safety issue.

(2) CFE recommends compliance with this ALERT service bulletin at the next access to the affected part (un-stretching the tie rod), the next MPI, CZI, or before the stage 1 turbine rotor disk reaches 2,450 Cycles Since New (CSN) and/or before the stage 2 turbine rotor disk reaches 2,930 CSN, whichever occurs first. Refer to Table 2 for affected HPT stage 1 disk and Table 3 for affected HPT stage 2 disk serial numbers.
