SUBJECT - AVIATION SAFETY ACTION MESSAGE, MAINTENANCE MANDATORY,
RCS CSGLD-1860(R1), ALL H-47 SERIES HELICOPTERS, HYDRAULIC FLUID
SAMPLING FROM FLIGHT CONTROL AND UTILITY SYSTEMS, CH-47-00-ASAM-03,
(TB 1-1520-240-20-121).
NOTE
THIS IS AN AVIATION SAFETY ACTION MESSAGE ISSUED IAW AR 95-1,
CHAPTER 6, 1 SEP 97. THIS MESSAGE HAS NOT BEEN TRANSMITTED TO
UNITS SUBORDINATE TO ADDRESSEES. ADDRESSEES SHOULD IMMEDIATELY
RETRANSMIT THIS MESSAGE TO ALL SUBORDINATE UNITS, ACTIVITIES OR
ELEMENTS AFFECTED OR CONCERNED. THE RETRANSMITTAL SHALL
REFERENCE THE MESSAGE. ACTION ADDRESSES WILL IMMEDIATELY VERIFY
THIS TRANSMISSION TO CDR, AMCOM, ATTN: AMSAM-SF-A (SOF
COMPLIANCE OFFICER).
1. PRIORITY CLASSIFICATION -
NOTE
IAW AR 95-1, PARA 6-6A, MACOM COMMANDERS MAY AUTHORIZE TEMPORARY
EXCEPTION FROM ASAM MESSAGE REQUIREMENTS. EXCEPTION MAY ONLY
OCCUR WHEN COMBAT OPERATIONS OR MATTER OF LIFE OR DEATH IN CIVIL
DISASTERS OR OTHER EMERGENCIES ARE SO URGENT THAT THEY OVERRIDE
THE CONSEQUENCES OF CONTINUED AIRCRAFT OPERATION.
A. AIRCRAFT IN USE - UPON RECEIPT OF THIS MESSAGE, MAKE THE
FOLLOWING ENTRY ON THE DA FORM 2408-13-1. THE RED HORIZONTAL
DASH //-//ENTRY SHALL STATE: "INSPECT H-47 SERIES AIRCRAFT IAW CH-
47-00-ASAM-03 WITHIN THE NEXT 10 FLIGHT HOURS BUT NLT 15 JUNE
2000." THE RED HORIZONTAL DASH //-// MAY BE CLEARED WHEN THE
INSPECTION OF PARA 8 IS COMPLETED. THE AFFECTED AIRCRAFT SHALL
BE INSPECTED AS SOON AS PRACTICAL BUT NO LATER THAN 15 JUNE 2000.
COMMANDERS WHO ARE UNABLE TO COMPLY WITH THE REQUIREMENTS OF THIS
MESSAGE WITHIN THE TIME FRAME SPECIFIED WILL UPGRADE THE AFFECTED
AIRCRAFT STATUS SYMBOL TO A RED //X//.
B. AIRCRAFT IN DEPOT MAINTENANCE - SAMPLE BEFORE FLIGHT.
C. AIRCRAFT UNDERGOING MAINTENANCE - SAMPLE BEFORE FLIGHT.
D. AIRCRAFT IN TRANSIT -
(1) SURFACE/AIR SHIPMENT - SAME AS PARA 1A.
(2) FERRY STATUS -
(A) SAME AS PARA 1A.
(B) THOSE AIRCRAFT THAT HAVE A DD 250 AND ARE AT
BOEING HELICOPTERS, PHILADELPHIA WILL BE INSPECTED PRIOR TO FERRY
TO FINAL DESTINATION.
E. MAINTENANCE TRAINERS (CATEGORY A AND B) - SAME AS PARA 1A.
F. COMPONENT/PARTS IN STOCK AT ALL LEVELS (DEPOT AND OTHERS)
INCLUDING WAR RESERVES - N/A.
G. COMPONENTS/PARTS IN WORK (DEPOT LEVEL AND OTHERS) - N/A
2. TASK/INSPECTION SUSPENSE DATE - WITHIN THE NEXT 10 FLIGHT
HOURS BUT NLT 15 JUNE 2000.
3. REPORTING COMPLIANCE SUSPENSE DATE - REPORT COMPLIANCE IAW
PARA 14A NLT 23 JUNE 2000.
4. SUMMARY OF PROBLEM -
A. THE H-47 COMMUNITY HAS REPORTED SEVERAL INCIDENTS IN
WHICH THE AIRCRAFT EXPERIENCED UNCOMMANDED MANEUVERS OR FLIGHT
CONTROL LOCK UP WHILE IN FLIGHT. CONTAMINATED HYDRAULIC FLUID IS
A FACTOR WHICH HAS BEEN PRESENT AND MAY HAVE CONTRIBUTED TO THE
UNCOMMANDED MANEUVERS OR FLIGHT CONTROL LOCK UP. TO RESOLVE THIS
HYDRAULIC FLUID CONTAMINATION FACTOR, A PERIODIC SAMPLING
INTERVAL OF 50 FLIGHT HOURS OR 100 CALENDAR DAYS FOR THE NUMBER
ONE, NUMBER TWO, AND UTILITY HYDRAULIC SYSTEMS WILL BE INITIATED.
B. FOR MANPOWER/DOWNTIME AND FUNDING IMPACTS SEE PARA 12.
C. THE PURPOSE OF THIS MESSAGE IS TO REQUIRE PERIODIC
SAMPLING OF HYDRAULIC FLUID FOR CONTAMINATION.
5. END ITEMS TO BE INSPECTED - ALL H-47 AIRCRAFT.
6. ASSEMBLY COMPONENTS TO BE INSPECTED - N/A.
7. PARTS TO BE INSPECTED - N/A.
8. INSPECTION PROCEDURES -
A. A THREE OUNCE HYDRAULIC FLUID SAMPLE WILL BE TAKEN EVERY
50 FLIGHT HOURS OR 100 CALENDAR DAYS FROM THE AIRCRAFTS NUMBER
ONE, NUMBER TWO, AND UTILITY HYDRAULIC SYSTEMS. THE INITIAL
SAMPLE WILL BE TAKEN WITHIN 10 FLIGHT HOURS BUT NLT 15 JUNE 2000.
THE THREE OUNCE HYDRAULIC FLUID SAMPLES WILL BE TAKEN IN
ACCORDANCE WITH TASK 7-8.1 OF TM 55-1520-240-23 OR TASK 7-11 OF
TM 1-1520-252-23. THE SAMPLES WILL BE SENT TO THE UNITS
DESIGNATED ARMY OIL ANALYSIS PROGRAM (AOAP) LABORATORY FOR
ANALYSIS.
NOTE
CORRECT HYDRAULIC SAMPLING PROCEDURES ARE
PARAMOUNT TO A SUCCESSFUL SAMPLING PROGRAM.
THE MAJORITY OF BAD SAMPLES ARE THE RESULT
OF IMPROPER SAMPLING, INADEQUATE DRAINING
AND TAKING OF SAMPLES.
B. EFFECTIVE WITH THIS MESSAGE, ALL HYDRAULIC FLUID FILTER
ELEMENTS WHICH ARE REMOVED FROM THE AIRCRAFT FOR NORMAL
MAINTENANCE REPLACEMENT WILL BE SENT TO THE UNITS DESIGNATED
AOAP LABORATORY FOR ANALYSIS.
C. ALL HYDRAULIC TEST STANDS (DEPOT AND ORGANIZATIONAL),
AUXILIARY GROUND POWER UNITS (AGPU) AND HYDRAULIC CARTS, WILL HAVE
FLUID SAMPLES ANALYZED EVERY SEVEN CALENDAR DAYS.
D. SPECIAL SAMPLES WILL BE TAKEN WHENEVER A MAJOR HYDRAULIC
COMPONENT (FOR EXAMPLE; THE PUMP, CHECK VALVE ETC.) HAS FAILED,
OR WHENEVER THE HYDRAULIC SYSTEM IS SUSPECT.
9. CORRECTION PROCEDURES -
A. CURRENTLY THE AOAP LABORATORIES ARE ABLE TO TEST FOR
WATER LEVELS IN HYDRAULIC FLUIDS. THE AOAP LABORATORIES ARE ALSO
CURRENTLY ABLE TO TEST FOR LEVELS OF PARTICULATE CONTAMINATION
(IN PARTS PER MILLION) OF SPECIFIC ELEMENTS WHICH INCLUDE IRON,
ALUMINUM, CHROMIUM, COPPER, SILICON, SODIUM, NICKEL, AND ZINC.
(1) FOR AIRCRAFT SYSTEMS USING MIL-H-83282, THE MAXIMUM
LIMIT FOR WATER IS 350 PARTS PER MILLION. FOR HYDRAULIC FLUID
WHICH HAS BEEN VERIFIED BY AOAP AS EXCEEDING 350 PARTS PER
MILLION OF WATER, CHANGE THE AIRCRAFT STATUS TO A RED //X//. THE
AIRCRAFT RED //X// STATUS MAY BE CLEARED UPON SUCCESSFUL
HYDRAULIC PURIFICATION, RE-SAMPLING, AND VERIFICATION BY THE AOAP
LABORATORY.
(2) FOR AIRCRAFT SYSTEMS USING MIL-H-5606, THE MAXIMUM
LIMIT FOR WATER IS 250 PARTS PER MILLION. FOR HYDRAULIC FLUID
WHICH HAS BEEN VERIFIED BY AOAP AS EXCEEDING 250 PARTS PER
MILLION OF WATER, CHANGE THE AIRCRAFT STATUS TO A RED //X//.
THE AIRCRAFT RED //X// STATUS MAY BE CLEARED UPON SUCCESSFUL
HYDRAULIC PURIFICATION, RE-SAMPLING, AND VERIFICATION BY THE AOAP
LABORATORY.
(3) ALL DATA GENERATED FOR LEVELS OF PARTICULATE
CONTAMINATION OF SPECIFIC ELEMENTS FROM THE AOAP ANALYSIS WILL BE
KEPT FOR STATISTICAL PURPOSES IN ORDER TO DETERMINE TRENDS WHICH
WOULD LEAD TO COMPONENT REPLACEMENT. IN THE CASE OF ABNORMAL
LEVELS OF PARTICULATE CONTAMINATION WHICH HAS BEEN VERIFIED BY
AOAP, THE AOAP LABORATORY WILL NOTIFY THE UNIT IMMEDIATELY. THE
AIRCRAFT STATUS WILL BE CHANGED TO A RED //X//. THE AIRCRAFT RED
//X// STATUS MAY BE CLEARED UPON SUCCESSFUL HYDRAULIC
PURIFICATION, RE-SAMPLING AND VERIFICATION BY AOAP LABORATORY.
IF SYSTEM IS STILL CONTAMINATED, CONTACT TECHNICAL POINT OF
CONTACT LISTED IN PARA 16A FOR CORRECTIVE ACTION.
(4) WHENEVER THE AGPU AND PURIFIER ARE USED, RECORD THE
FOLLOWING ON THE AIRCRAFT DA FORM 2408-15 -
(A) DATE OF PURIFICATION, SERIAL NUMBER/ADMIN
NUMBER OF AGPU.
(B) SERIAL NUMBER/ADMIN NUMBER OF PURIFIER.
(C) AIRCRAFT HOURS.
(D) HOUR METER START AND COMPLETION TIMES OF THE
PURIFIER AND AGPU.
(5) ORGANIZATIONAL OWNED HYDRAULIC TEST STANDS, DEPOT
TEST STANDS, AUXILIARY GROUND POWER UNITS (AGPU) AND HYDRAULIC
CARTS USING MIL-H-83282 HYDRAULIC FLUID WILL BE MAINTAINED TO A
MAXIMUM OF 200 PARTS PER MILLION FOR WATER. TEST STANDS, AGPU
AND HYDRAULIC CARTS USING MIL-H-5606 HYDRAULIC FLUID WILL BE
MAINTAINED TO A MAXIMUM OF 175 PARTS PER MILLION FOR WATER. A
HYDRAULIC FLUID SAMPLE WILL BE TAKEN EVERY SEVEN DAYS FOR ALL
TEST STANDS AND AGPU CARTS AND RECORDED ON THE EQUIPMENT DA FORM
2408-20. THIS SAMPLE WILL BE PROCESSED PER TB 43-0106. THE
SAMPLE WILL BE TAKEN AT THE GAUGE CALIBRATION PORT. USE THE 3 OZ
OUNCE SAMPLE BOTTLE. AS NOTED IN TB 43-0106, ALL THE HYDRAULIC
FLUID, INCLUDING THAT IN THE AGPU RESERVOIR SHOULD BE WARM AND
RECENTLY CIRCULATED PRIOR TO SAMPLING. A DA FORM 2408-20 WILL BE
ESTABLISHED BY THE UNIT TO RECORD AND TRACK AGPU HYDRAULIC OIL
SAMPLES.
B. AT PHASE INSPECTION, PURGE THREE OUNCES OF HYDRAULIC
FLUID FROM THE NUMBER ONE AND NUMBER TWO SIDES OF THE ROLL,
PITCH, AND YAW INTEGRATED LOWER CONTROL ACTUATOR(ILCA) EXTENSIBLE
LINK BLEED PORT IN ACCORDANCE WITH TASK 7-16 OF TM 55-1520-240-23
OR TASK 7-19 OF TM 1-1520-252-23. THIS PROCEDURE IS REQUIRED TO
REMOVE UNCIRCULATED FLUID FROM THE EXTENSIBLE LINKS OF EACH ILCA.
