WARNING: FAILURE TO COMPLY WITH THIS SERVICE BULLETIN COULD

RESULT IN DISTRESS TO THE HPC2 DISC, PN 2-101-332-12. IF LEFT

UNCORRECTED, THIS DISTRESS COULD RESULT IN AN UNCONTAINED

SEPARATION AND RELEASE OF HIGH ENERGY FRAGMENTS, AND

COULD CAUSE SERIOUS INJURY OR DEATH TO PERSONNEL, AND

DAMAGE TO, OR LOSS OF THE AIRCRAFT.

C. Reason

(1) Problem: Cracks were found in a low-time T55 HPC2 disc (common to all

ALF502/LF507 engines), PN 2-101-332-12, during routine inspection. This service

bulletin gives instructions to remove suspect HPC2 discs, PN 2-101-332-12, which

were produced from the same material ingot.

(2) Background: The cracks that were found in a low-time HPC2 disc, PN 2-101-332-12,

were determined to have initiated during the manufacturing process. The serial

numbers of the suspect HPC2 discs, PN 2-101-332-12, have been identified and the

last known engine in which they were installed has also been identified.

(3) Benefits: Removal of the identified serial number HPC2 discs, PN 2-101-332-12, from

operation as specified in this service bulletin will eliminate the possibility of a crack in

HPC2 discs, PN 2-101-332-12, propagating to failure.

(4) Action: Review engine records and remove the identified serial number HPC2

discs, PN 2-101-332-12, from operation and return the removed HPC2 discs, PN

2-101-332-12, to Honeywell.

D. Description

(1) This service bulletin requires the removal of specific HPC2 discs, PN 2-101-332-12,

from operation before they have accumulated 4,500 cycles, or before 7 years from the

release date of this service bulletin, whichever comes first.

E. Compliance

(1) Compliance addresses a safety issue.

(2) The warranty/program data is listed in Table 5.

NOTE: The procedures outlined in this service bulletin may be accomplished at the

Service Center level or greater.
