The Bell 212 helicopter was en route for firefighting duties, crash landing near Lo Conti. Pilot was rescued by a Chilean Army helicopter, taken to a Rancagua hospital. The tail boom was severed and skids collapsed.
Causes
Main Drive Shaft Disconnection (MDS), connecting the engines with the main transmission of the aircraft, causing a drop in the RPM of the main rotor, forcing the pilot to perform an emergency landing in autorotation, impacting the terrain with great energy.
Contributing Factors
- Loss of lubrication (grease) in the front coupling of the Main Drive Shaft (MDS).
- Increase in temperature in the coupling, affecting the hardness of the union teeth.
- Wear of the inner gear teeth and the disconnection of both components.
- Performing the aerodynamic braking maneuver (flare) before reaching the recommended height.
