What was found
(CAN) WHILE WAITING FOR HIS CREW TO RETURN, THE PILOT NOTICED SOME BLACK SOOT AROUND ONE OF THE STARFLEX ARMS. FURTHER EXAMINATION REVEALED THAT THE STAINLESS STEEL BUSHING BONDED ON THE END OF THE STARFLEX ARM HAD COME LOOSE AND WAS FLOATING INSIDE THE SPHERICAL BEARING IN THE FREQUENCY ADAPTER. THE BUSHING WAS IN GOOD CONDITION THAT MORNING BEFORE THE FLIGHT AND NO UNUSUAL NOISES OR VIBRATIONS WERE DETECTED PRIOR TO DISCOVERING THE DAMAGED STARFLEX. THE PILOT AND CREW HAD TO BE FLOWN OUT OF THE BUSH WITH ANOTHER HELICOPTER. A NEW STARFLEX WAS INSTALLED ON SITE THE NEXT DAY WITH NO FURTHER ISSUES. (TC NR 20070608006)
