What was found
MR SPINDLES BRINELLED AFTER 171.4 HOURS. THIS IS THE SECOND TIME THIS HAS HAPPENED TO THIS HELICOPTER IN THE LAST 336 HOURS. WHEN OFF THE HELICOPTER THE SPINDLE IS SO HARD TO TURN THAT YOU HAVE TO HOLD THE BLADE DOWN WITH ONE HAND TO GET IT PAST ITS FIRST DETENT. IN FLIGHT CONSTANT VIBRATIONS WERE FELT IN THE COLLECTIVE AND CYCLIC CONTROLS.
