Incident at 048:30 W 46:27 N (Oil Rig)

Summary

2003-04-01: TSB - Narrative - A Sikorsky SK61 helicopter crew was transporting 10 passengers and two crew to the offshore oil rig 'Henry Goodrich'. On lift off from St. John's the pilot felt the collective stick a bit. The collective friction was reduced and the stickiness disappeared. On approach to the oil rig the possibility of the collective sticking was discussed, and all friction was removed. Approaching the helideck the collective jammed as it was being raised, and it could not be raised further. The aircraft continued to descend over the deck. As ground cushion was encountered the aircraft stopped descending and came to a 10 foot hover. Rotor rpm was reduced to effect a successful landing. After landing the friction sleeve lock wire and friction block screws were removed. Free collective movement was attained and the flight continued without further incident. The collective friction had been adjusted the night before the occurrence. It was noted to be normal during the pre-flight checks.
