What was found
LEAKING, THIS LEAK IS WELL WITHIN LIMITS BUT THIS CAUSES UNNECESSARY CONTAMINATION ON TAILBOOM AND ASSOCIATED PARTS. THE OIL VENTS OUT OF THE GEARBOX (AS IT SHOULD), BUT THE EXTRA THAT CAN’T BE BURNT IN THE EXHAUST IS VENTED ON THE TAILBOOM AND TAIL ROTOR CAUSING PREMATURE WEAR ON ELASTOMERIC COMPONENTS. THE TIME OF THE COMPONENT IS IRRELEVANT AS THIS IS A COMMON PROBLEM WITH ALL 2B1 IN THE WINTER MONTHS.
