Occurrence
On 7 June 2021, a Bell 214ST helicopter operated by Helicopter Transport Services (Canada) Inc. was returning to Nipigon, Ontario, after fire suppression operations. The helicopter was carrying a collapsible bucket on a long line. During the flight, the pilot noticed a vibration in the tail rotor pedals accompanied by a grinding noise. Shortly thereafter, the low oil pressure warning lights for the two tail rotor gearboxes illuminated, followed immediately by a loss of yaw control.
Forced Landing
The pilot released the long line and declared a Mayday. A forced landing was conducted. The helicopter landed heavily and came to rest on its left side. The pilot, who was the sole occupant, was wearing a helmet and lap belt. The pilot was seriously injured and shut down the engines before exiting the aircraft.
Aftermath
The emergency locator transmitter activated. There was no fire. The helicopter sustained substantial damage. The investigation was classified as a class 4 investigation, which is limited in scope and does not include findings or recommendations.
