LOSS of Throttle Control and HARD Landing at Oshkosh

#N975BH #atc #helicopter
The airline transport pilot maneuvered the helicopter on the downwind leg of the airport traffic pattern and attempted to reduce power for landing; however, the engine power remained excessively high. The pilot attempted to further reduce the engine power by turning off one magneto and applying carburetor heat, but the power remained too high to safely descend. The pilot then entered a sideslip, which allowed the helicopter to descend to about 100 ft above the runway. He turned the engine power off and autorotated to the ground. The helicopter landed hard in a tail-low attitude. The main rotor struck the tail and the tail rotor assembly separated from the helicopter.
• LOSS of Throttle Contr...
A postaccident examination found that the throttle linkage nut had loosened and separated from its fitting, causing the throttle to remain open. The helicopter's maintenance manual did not specify a torque value for the throttle linkage nut, and there were no maintenance procedures requiring the nut to be loosened or removed during overhaul. The pilot indicated that a complete overhaul of the helicopter was completed about 37 hours before the accident flight.
Probable Cause: The loosening and separation of the throttle linkage nut, which resulted in a loss of throttle control and subsequent hard landing after autorotation.

You'd think the T6's were having the emergency by all the chatter.

[@BBQSauceman]

I know the T-6 leader wouldn’t shut up lol

[@CFITOMAHAWK]

THEY NEED ATTENTION those guys.

[@daveblevins3322]

Air shows at Oshkosh are like a Bravo airspace on steroids 💥💥

[@Flight_Follower]

Yeah 😅

[@tomheim8976]

what a cluster

Scary AF....good Comms, well handled all round.

[@Flight_Follower]

Good job done

[@pawepluta4883]

Very poorly handled. It would be well handled if he told everyone to shut up for 3 minutes until emergency is safe. Especially those on the ground who were even told that there is an emergency, but "OK, OK, sure, and now can we continue because we need to show off?".

[@realdjoffski7201]

No wonder air shows have a lot of accidents. They dont even know of a truck blocking cleared airplane. And that doesnt even fly. Hardly any control there.

[@user-jq2rf4nf3o]

Throttle? Bell 47? If you can't softly auto a Bell of any kind you should quit flying... Don't need a stinking throttle

[@AlbertHess-xy7ky]

Controllers....

[@pawepluta4883]

Terribly poor and unsafe communication.
