INSPECTION REQUIREMENTS, AND RELEASED SOME AIRCRAFT FOR
RESTRICTED FLIGHT. THE AIRCRAFT RELEASED FOR RESTRICTED FLIGHT
CONTAINED FORWARD AND AFT TRANSMISSIONS WHICH HAD ALL PLANETARY
GEAR BEARING ASSEMBLIES IDENTIFIED WITH THE SERIAL NUMBER PREFIX
"VB". THE RESTRICTION LIMITED FLIGHT OPERATIONS TO A MAXIMUM OF
80 PERCENT DUAL ENGINE TORQUE. ANALYTICAL INVESTIGATIONS,
TESTING OF DISCREPANT GEAR/BEARING ASSEMBLIES, RESULTS OF GEAR
BEARING ASSEMBLY INSPECTIONS, AND RESEARCH OF HISTORICAL DATA
HAVE LED TO A RISK DETERMINATION THAT THE 80 PERCENT DUAL ENGINE
TORQUE OPERATING LIMITATION IMPOSED BY SAFETY OF FLIGHT MESSAGE
CH-47-99-04 CAN BE INCREASED TO THE NEW OPERATING LIMITATION
IDENTIFIED IN PARAGRAPH 9.
NOTE
GEAR BEARING ASSEMBLIES WITH SERIAL NUMBER
PREFIX "GG" ARE CONSIDERED UNSERVICEABLE AND
SHALL BE INSPECTED IN ACCORDANCE WITH SAFETY
OF FLIGHT MESSAGE CH-47-99-03.
NOTE
TRANSMISSIONS WHICH HAVE HAD ALL GEAR/BEARING
ASSEMBLIES INSPECTED AND HAVE BEEN RE-IDENTIFIED
BY SERIAL NUMBER PREFIX "MG" ARE CONSIDERED
SERVICEABLE IN ACCORDANCE WITH SAFETY OF FLIGHT
MESSAGE CH-47-99-03.
B. FOR MANPOWER/DOWNTIME AND FUNDING IMPACTS SEE PARA 12.
C. THE PURPOSE OF THIS MESSAGE IS TO INCREASE TO 100
PERCENT DUAL ENGINE TORQUE, THE 80 PERCENT DUAL ENGINE TORQUE
LIMITATION IMPOSED BY SAFETY OF FLIGHT MESSAGE CH-47-99-04 ON
AIRCRAFT WITH BOTH TRANSMISSIONS WITH "VB" SERIAL NUMBERED
GEAR/BEARING ASSEMBLIES INSTALLED.
5. END ITEMS TO BE INSPECTED ALL H-47 SERIES AIRCRAFT.
6. ASSEMBLY COMPONENTS TO BE INSPECTED N/A.
7. PARTS TO BE INSPECTED - N/A.
8. INSPECTION PROCEDURES INSPECT THE AIRCRAFT DA FORM 2408-13
AND 2408-13-1 FOR A CIRCLED RED //X// ENTRY WHICH STATES
"AIRCRAFT RESTRICTED TO FLIGHT OPERATIONS AT A MAXIMUM OF 80
PERCENT DUAL ENGINE TORQUE." AIRCRAFT OPERATING UNDER THIS
FLIGHT RESTRICTION WILL HAVE A NEW OPERATING LIMITATION AS
DEFINED IN PARAGRAPH 9.
9. CORRECTION PROCEDURES - THE CIRCLED RED //X// CONDITION
STATUS SYMBOL AND ENTRY PREVIOUSLY ENTERED IN ACCORDANCE WITH
SAFETY OF FLIGHT MESSAGE CH-47-99-04 STATING "AIRCRAFT RESTRICTED
TO FLIGHT OPERATIONS AT A MAXIMUM OF 80 PERCENT DUAL ENGINE
TORQUE." SHALL BE CLEARED. A NEW CIRCLED RED //X// ENTRY SHALL
STATE "AIRCRAFT RESTRICTED TO FLIGHT OPERATIONS AT A MAXIMUM OF
100 PERCENT DUAL ENGINE TORQUE." FOR AIRCRAFT THAT EXCEED THE
100 PERCENT DUAL ENGINE TORQUE LIMIT, CHANGE THE AIRCRAFT
CONDITION STATUS SYMBOL TO A RED //X//. THE RED //X// ENTRY
SHALL STATE "AIRCRAFT EXCEEDED 100 PERCENT DUAL ENGINE TORQUE
LIMITATION, REPLACE FORWARD AND AFT MAIN TRANSMISSIONS IAW SOF CH-
47-00-03." AIRCRAFT WHICH EXCEED THIS LIMITATION ARE AUTHORIZED
A ONE TIME FLIGHT, TO THE NEAREST SECURE MAINTENANCE FACILITY.
NOTE
AIRCRAFT PLACED ON A RED //X// CONDITION STATUS
AS A RESULT OF THIS MESSAGE WILL REQUIRE REPLACEMENT
OF THE FORWARD AND AFT TRANSMISSIONS. TRANSMISSIONS
WHICH EXCEED THE 100 PERCENT DUAL ENGINE TORQUE
OPERATIONAL LIMITATION WILL REQUIRE OVERHAUL, AT
WHICH TIME THEY WILL BE INSPECTED AND RE-IDENTIFIED IN
ACCORDANCE WITH SAFETY OF FLIGHT MESSAGE CH-47-99-03.
THE REPLACEMENT OF COMPONENTS IAW PARA 9. OF THIS
MESSAGE CONSTITUTES A CONDITION CHANGE AND WILL NOT
BE INCLUDED IN ACCIDENT COST COMPUTATIONS IAW AR 385-
