A. DURING THE SCHEDULED MAINTENANCE OF A ROTOR HEAD
ASSEMBLY, TAPE WAS DISCOVERED COVERING ONE OF SIX OIL LUBE
PORTS ON THE UPPER SURFACE OF THE ROTOR HUB. THESE PORTS

BEARINGS. THE TAPE IS USED TO PROTECT THE OIL PASSAGES
DURING PAINTING AND MAY HAVE BEEN ACCIDENTALLY LEFT IN PLACE
DURING OVERHAUL PRODUCTION. A COMPLETE OR PARTIAL
RESTRICTION OF LUBRICATING OIL TO THE HORIZONTAL HINGE PIN
BEARINGS CAUSES PREMATURE WEAR AND RESULTS IN DAMAGE TO THE
BEARINGS AND RELATED COMPONENTS.
B. FOR MANPOWER/DOWNTIME AND FUNDING IMPACTS SEE PARA
12.
C. THE PURPOSE OF THIS MESSAGE IS A ONE TIME
INSPECTION OF ALL CH-47D, MH-47D AND MH-47E FORWARD AND AFT
