UPDATE: TSB#A15P0217: The Medevac Helijet Sikorsky S76C (C-GHHJ) was conducting a night approach at Tofino/Long Beach, BC (CYAZ) on a VFR flight from Vancouver Intl, BC (CYVR). After flying an autopilot coupled approach (RNAV29) to an altitude of 600 feet MSL in the vicinity of the threshold to Runway 29, the crew uncoupled the autopilot and continued to maneuver visually for the planned landing area. While on final approach, a high rate of descent (1100 fpm) and low airspeed developed, accompanied by a violent left and right movement. The crew applied collective and forward cyclic input and the aircraft recovered at low level and airspeed. Subsequent engine and airframe indications appeared to be normal and the crew completed a second approach for an uneventful landing. A post landing inspection revealed the presence of oil on the rotor blades and airframe. A maintenance inspection confirmed that the rotor hub spindles and a damper were damaged. , 2018-01-03 - UPDATE According to the TSB Final Report A15P0217 authorized for release on the 20th of December 2017: On 15 November 2015, at 0135 Pacific Standard Time, the Helijet International Inc.

While conducting a visual approach to Runway 29, the crew disengaged the autopilot at an altitude of 600 feet above sea level and manoeuvred toward the planned landing area. At approximately 0239, on short final, the helicopter's airspeed slowed, a high rate of descent developed, rotor speed began to decrease, and directional control was lost. Control was re-established over a beach, after the helicopter had descended to approximately 3 feet above ground level, and approximately 67 feet below the airfield elevation at Tofino/Long Beach Airport. The pilots then observed normal engine and drivetrain parameters and climbed to 500 feet above sea level to conduct a second approach. During this approach, additional control difficulties were encountered, but the helicopter was able to land. There were no injuries, there was no fire, and the emergency locator transmitter was not activated., 2015-11-18 - The pilot of a Helijet International Sikorsky S-76C (C-GHHJ) from Vancouver, BC (CYVR) to Tofino, BC (CYAZ) reported issues with main rotor on final approach Runway 29.
