ENGINE WITH SUBSEQUENT ENGINE FAILURE.  THE STRAP ASSEMBLY
WAS REMOVED AND RETURNED TO BOEING HELICOPTERS FOR ANALYSIS.
THE RESULTS OF THAT ANALYSIS SHOWED THAT A POLYSULFIDE
SEALANT (PRO-SEAL 890) HAD BEEN USED ON THE STRAP ASSEMBLY
INSTEAD OF THE PRESCRIBED ADHESIVE.
     B.  FOR MANPOWER/DOWNTIME AND FUNDING IMPACTS SEE PARA
12.
     C.  THE PURPOSE OF THIS MESSAGE IS TO CONDUCT A VISUAL
INSPECTION TO DETERMINE IF THE PROPER ADHESIVE HAS BEEN USED

PROVIDED IF THE ASSEMBLY FAILS THE VISUAL INSPECTION.
5.  END ITEMS TO BE INSPECTED - ALL CH-47D, MH-47D AND MH-
47E AIRCRAFT.  MH-47E AIRCRAFT WHICH HAVE PREVIOUSLY DONE

     B.  OPEN THE ENGINE WORK PLATFORMS.
     C.  REMOVE THE ENGINE AIR INLET SCREENS.  (REF TM 55-
1520-240-23 TASK 4-65 FOR CH-47D/MH-47D, OR TM 1-1520-252-
23, TASK 4-26 FOR MH-47E).
     D.  INSPECT THE BOND LINES ON THE 114P8079-2 AND -3
STRAP ASSEMBLIES FOR LOOSENESS AROUND THE EDGES.  THE EDGES
SHOULD BE SECURELY ADHERED AND SHOULD NOT LIFT UP.  IF THE
STRAP ASSEMBLIES PASS THE INSPECTION, REINSTALL THE INLET
SCREENS ON THE AIRCRAFT AND THE INSPECTION IS COMPLETE.  IF
STRAP ASSEMBLIES FAIL THE INSPECTION PROCEED TO PARAGRAPH 9
FOR CORRECTIVE ACTION.
9.  CORRECTION PROCEDURES -
     A.  REMOVE EXISTING SILICONE RUBBER PAD FROM THE STRAP
ASSEMBLY.
     B.  FABRICATE A NEW PAD FROM SILICONE RUBBER BMS1-23,
DIMENSIONS 0.25 INCH THICK X 1.0 INCH WIDE X 24.0 INCHES
LONG.
     C.  PREPARE THE ALUMINUM STRAP FOR BONDING AS FOLLOWS:
          1.  ABRADE THE SURFACE USING SCOTCHBRITE OR 180
GRIT SANDPAPER.
          2.  SOLVENT WIPE THE SURFACE USING ACETONE.
          3.  PRIME THE SURFACE BY BRUSHING OR SPRAYING WITH
A THIN COAT OF SS4004 OR RTV 1200 PRIMER.  NOTE:  IF THE
PRIMER TURNS CLOUDY OR MILKY IT SHOULD NOT BE USED.
          4.  ALLOW THE PRIMER TO AIR DRY FOR 30 MINUTES
MINIMUM AND 4 HOURS MAXIMUM.
     D.  PREPARE THE SILICONE RUBBER PAD FOR BONDING AS
FOLLOWS:
          1.  A PARTING AGENT ON MOLDED PARTS IS USUALLY
EMBEDDED IN THE RUBBER.  WIPE THE BOND SURFACE WITH ACETONE,
METHYL-ETHYL-KETONE, OR ALIPHATIC NAPTHA THEN SAND THE PART
TO REMOVE THE PARTING AGENT USING 180 GRIT SANDPAPER.
          2.  REMOVE THE SANDING DEBRIS BY WIPING WITH
ACETONE, METHYL-ETHYL-KETONE, OR ALIPHATIC NAPHTHA.
     E.  BOND THE NEW PAD TO THE STRAP AS FOLLOWS:
          1.  APPLY A UNIFORM LAYER OF RTV 102 ADHESIVE OVER
BOTH MATING SURFACES.
          2.  JOIN THE MATING SURFACES AS SOON AS POSSIBLE
AFTER ADHESIVE APPLICATION.  EXPOSURE TO THE AIR FOR MORE
THAN A FEW MINUTES WILL CAUSE THE ADHESIVE TO FORM A SKIN
WHICH INTERFERES WITH ADHESION.
          3.  APPLY SUFFICIENT PRESSURE TO ENSURE COMPLETE
CONTACT BUT NOT SO MUCH AS TO SQUEEZE OUT AN EXCESSIVE
AMOUNT OF ADHESIVE.  A BOND LINE THICKNESS OF 15 MILS GIVES
THE BEST RESULTS.
          4.  ALLOW THE ADHESIVE TO CURE FOR A MINIMUM OF 24
HOURS AT 75 + 5 F.  A MINIMUM OF 20% RELATIVE HUMIDITY IS
REQUIRED.
