3.  REPORTING COMPLIANCE SUSPENSE DATE - NO LATER THAN 29 OCT 99
IAW PARA 14A OF THIS MESSAGE.
4.  SUMMARY OF PROBLEM -
    A.  BACKGROUND
        (1)  IN 1995 THERE WAS AN INCIDENT WHERE AN APU COMPRESSOR
WHEEL BURST DURING START-UP (SEE REFERENCE 13A).  THE FAILURE WAS
ATTRIBUTED TO FATIGUE WHICH ORIGINATED FROM BOLTHOLES ON THE BACK OF
THE WHEEL (SEE REFERENCE 13B).  THE DAMAGING FATIGUE CYCLES ARE
INCURRED BY STARTING THE APU.
       (2)  PREVIOUSLY, APU STARTS HAVE NOT BEEN RECORDED AND HAVE
NOT BEEN MAINTAINED AND TRANSFERRED WITH THE APU.  CURRENTLY, START
CYCLES FOR A PARTICULAR COMPRESSOR WHEEL ARE ESTIMATED BASED ON THE
HOURS LOGGED ON THE AIRCRAFT RECORDS.  THE ESTIMATES USE FOUR APU
STARTS FOR ONE FLIGHT HOUR.
       (3)  APU'S OVERHAULED SINCE NOVEMBER 1996 WERE SUBJECT TO
MAGNETIC PARTICLE INSPECTION OF THE COMPRESSOR WHEEL FOR FATIGUE
CRACKS AND ARE GIVEN A ONE-TIME LIFE EXTENSION OF 2100 STARTS SINCE
INSPECTION AT DEPOT (SEE "NOTE" IN PARA 9).  ONLY APU'S SPECIFICALLY
LISTED IN PARAGRAPH 9B BELOW ARE AUTHORIZED TO OPERATE UP TO 525 HRS
OR 2100 STARTS SINCE INSPECTION (SSI). FUTURE APUS FROM DEPOT SHALL
HAVE FORMS AND RECORDS REFLECTING THIS NEW RETIREMENT LIFE.
       (4)  THE DATA FROM THESE INSPECTIONS INDICATE THAT WITH NO
LIFE LIMIT, WHICH IS THE CURRENT SITUATION, THE T-62T-2B APU
COMPRESSOR WHEEL HAS A HIGH PROBABILITY OF CATASTROPHIC FAILURE.
IN THE EVENT OF AN IMPELLER BURST, UP TO THREE PIECES OF THE IMPELLER
MAY EXIT THE APU RADIALLY.  THESE PIECES WILL WEIGH UP TO 1.1 POUNDS
EACH AND WILL BE MOVING AT EXTREMELY HIGH VELOCITY.
       (5)  A NEW DESIGN HAS BEEN APPROVED FOR THE COMPRESSOR WHEEL
WHICH WILL HAVE A GREATER FATIGUE LIFE.  THE NEW WHEELS WILL BE
INCORPORATED BY OLR TEAM USING MWO OR BY DEPOT.
    B.  FOR MANPOWER/DOWNTIME AND FUNDING IMPACTS SEE PARA 12.
    C.  THE PURPOSE OF THIS MESSAGE IS TO IMPOSE A RETIREMENT LIFE ON
APU COMPRESSOR WHEELS INSTALLED ON APU P/N 160150-10 OR 160150-100
AND STARTS SINCE INSPECTION (SSI) LIMITS FROM TIME OF DEPOT
INSPECTION.  ADDITIONALLY, THIS MESSAGE ADDS HISTORICAL RECORD
REQUIREMENTS THAT WILL ALLOW TRACKING OF APU USAGE BY STARTS.  IT
ALSO IMPOSES RESTRICTIONS ON APU'S WITH NON-INSPECTED WHEELS.
5.  END ITEMS AFFECTED - ALL CH-47D, MH-47D, AND MH-47E AIRCRAFT.
6.  ASSEMBLY COMPONENTS TO BE INSPECTED  T-62T-2B (APU), P/N
160150-10 OR 160150-100.
7.  PARTS TO BE INSPECTED - N/A.
8.  INSPECTION PROCEDURES
    A.  INSPECT AIRCRAFT CONDITION CHANGE DA FORM 2408-16 TO
DETERMINE TIME SINCE NEW (TSN) OF THE APU (BASED UPON AIRCRAFT
FLIGHT HOURS).
    B.  IF THE APU SERIAL NUMBER IS LISTED IN PARAGRAPH 9B BELOW, IT
HAS A COMPRESSOR WHEEL WHICH WAS INSPECTED DURING DEPOT OVERHAUL.
DETERMINE THE TIME IT HAS BEEN OPERATING SINCE THE INSPECTION.  IF
HOURS CANNOT BE DETERMINED, CONTACT EITHER 2410 HOTLINE (LISTED IN
PARA 16D) OR LOGISTICAL POC (LISTED IN PARA 16B).
                           NOTE
         ALL HISTORICAL RECORD DATA FOR APU HOURS
         REFERS TO AIRCRAFT OPERATING TIME, NOT APU
         OPERATING TIME.
    C.  FOR TSN (8A ABOVE) AND TIME SINCE INSPECTED IF APPLICABLE
(8B ABOVE), CALCULATE THE STARTS ACCUMULATED.  MULTIPLY THE TSN AND
THE AIRCRAFT TIME SINCE INSPECTED BY 4.  THIS CALCULATED NUMBER OF
STARTS BASED UPON APU TIME SINCE NEW WILL BE USED TO DETERMINE THE
LIFE LIMIT AND RESTRICTIONS AS STATED IN PARAGRAPH 9C BELOW AS WELL
AS THE BASIS FOR RECORDING AND MAINTAINING APU STARTS IN THE FUTURE.
THE TIME SINCE INSPECTED START NUMBER WILL BE USED TO ALLOW EXTENDED
LIFE OF THE APU WHEEL BASED UPON THE INSPECTION AND PREDICTED CRACK
GROWTH PROPAGATION.
9.  CORRECTION PROCEDURES
                            NOTE
          THE 5360 STARTS SINCE NEW MAY ONLY BE EXCEEDED
          IF THE APUS HAVE UNDERGONE NDI INSPECTION OF
          THE COMPRESSOR WHEEL.  IN THIS CASE AN
          ADDITIONAL 2100 STARTS SINCE INSPECTION IS
          AUTHORIZED REGARDLESS OF THE ORIGINAL STARTS
          SINCE NEW.
     A.  ANY APU EXCEEDING 5360 STARTS IS UNSERVICEABLE (1340 TIMES 4
EQUALS 5360) UNLESS A NDI INSPECTION OF COMPRESSOR WHEEL WAS
PERFORMED  AT OVERHAUL OR EXTENSION IS AUTHORIZED PER PARA 9B.
     B. THE FOLLOWING T-62T-2B APU'S HAVE AN OPERATING LIMIT OF
2100 STARTS SINCE INSPECTION (SSI) (525 HOURS TIMES 4 EQUALS 2100
STARTS).  FOR APUS LISTED USE EITHER STARTS SINCE NEW (5360) OR
STARTS SINCE INSPECTION (2100) TO ESTABLISH THE LIMIT WHICHEVER
YIELDS THE GREATER REMAINING LIFE.
