Incident at ST. JOHN'S INTL NL (CYYT)

Summary

2003-12-24: TSB Update - A03A0133: A Cougar Helicopters Eurocopter AS-332, registration C-GQCH, had just departed the Hibernia oil production platform with 2 crew and 11 passengers on board en route to St. John's, NL when a loud 'bang' was heard by the crew and passengers. The crew elected to return to the platform for a visual inspection. After landing, a visual inspection of the exterior did not reveal any abnormalities. After shutdown, the engines, drive train and landing gear were inspected with no observed abnormalities. Maintenance requested a hover check and cycle the landing gear. All systems other than the gear appeared to function normally. The gear was cycled to the down position but the crew did not receive a down and locked indication in the cockpit. Platform personnel, observing the extension, advised the crew that the gear did not appear to be extended properly. The crew left the hover, retracted the gear and flew to St. John's. At 30 nm from St. John's, the crew selected the gear down and again did not receive a down and locked indication so an emergency gear extension procedure was completed. A down and locked indication was obtained. Upon arrival at St. John-s, the aircraft was escorted to the apron by AFF vehicles and landed safely at 1857 NST without further incident. The AS-332 landing gear position is determined by a series of proximity switches controlled by a landing gear control circuit board. Maintenance personnel replaced the circuit board, cycled the landing gear numerous times and confirmed normal functioning of the landing gear and indication system. The aircraft was returned to service.
2003-12-19: An AS32 Helicopter operated by Cougar Helicopters departed Hibernia for St. John's. When the helicopter was 80 nautical miles South-East of St. John's the pilot declared an emergency due to landing gear problems. The AS32 hovered in St. John's and it was determined that the gear was safely down then the emergency was cancelled and they landed at 2227Z without incident. TSB - A03A0133 - Case Closed More to Follow.
