Accident Number: ERA20LA310
Date & Time: 09/06/2020, 0900 EDT
Registration: N194HC
Aircraft: Robinson R22
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

On September 6, 2020, about 0900 eastern daylight time, a Robinson R22 Mariner helicopter, N194HC, was involved in an accident at Page Field (FMY), Fort Myers, Florida. The flight instructor and pilot receiving instruction were not injured. The instructional flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

Both pilots submitted written statements, and their versions of events were consistent throughout. The preflight and engine-start procedures were completed by the checklist with no anomalies noted. As the engine was accelerated to near its operating rpm, each pilot heard a loud "bang." The student leaned out his door and announced that "the tail was hanging off the back of the aircraft." The engine was stopped, and the event was reported to the helicopter's owner and his mechanic.

Examination of photographs revealed damage to the tailrotor gearbox, tailrotor blades, and the tailcone's section forward of the tailrotor gearbox. These areas and components were sectioned and forwarded to the NTSB Materials Laboratory in Washington, DC for examination.

  1. Lucky it happened on the ground and not on flight,sounds like some seizure and torque to do that ?

    1. ^^Or a a failure of at least one of the rotor blade mount points causing it to droop when the rotor RPM got high enough. Normally this happens (rotor blade striking tail boom) when there is a hard landing on autorotation, simulated or real. I'm not a rotary rated pilot but I do have some dual stick time, so perhaps someone with a helicopter rating here can explain more what can happen to cause this. The fact they felt no vibration issue out of the norm during rotor RPM run-up out before the tail boom was hit is a clue that something failed and failed very fast.

    2. Read info again, main blade did not hit the boom. Sudden seize in the gear box, probably a fragment jammed the gear set.

  2. You can be the best pilot in the world with thousands of safe flights, but when this happens at altitude......
