Location: Danbury, TX 
Accident Number: CEN19LA187
Date & Time: 06/28/2019, 1132 CDT
Registration: N26498
Aircraft: Robinson R22
Aircraft Damage: Substantial
Defining Event: Sys/Comp malf/fail (non-power)
Injuries: 1 None
Flight Conducted Under: Part 137: Agricultural 

On June 28, 2019 at 1132 Central Daylight Time, a Robinson R-22 Beta helicopter, N26498, impacted terrain near Danbury, Texas. The commercial pilot was not injured. The helicopter was substantially damaged. The helicopter was registered to a corporation and operated as a 14 Code of Federal Regulations Part 137 pollination flight. Visual meteorological conditions were reported at the accident site and along the route of flight about the time of the accident.

The pilot reported to the FAA he was conducting pollination activities when the "clutch" light illuminated and would not go out and he began to loose power, so he "set it down" in the field. He pilot told the mechanic selected to repair the helicopter that he was flying low over the agricultural field when the "GOV" (governor) caution light illuminated, followed by the "clutch light" illuminating. He felt the helicopter began to lose rotor speed and responded by rolling the engine power. He landed the helicopter vertically and did not split the skids; however, the main rotor speed decayed sufficiently enough that a main rotor blade drooped and struck the tail cone, substantially damaging the helicopter.

The mechanic reported that during an examination of the helicopter the "actuator" engaged and disengaged normally, the drive belts were in good condition, and the clutch rotated normally. The governor light remained illuminated regardless of the switch position. He traced the light to a faulty electrical relay that caused the light to illuminate, and stated the faulty relay would only cause the light to come on and would not affect the governor operation. He verified the governor operated normally when electrical power was applied. No other anomalies were found with the helicopter.

It seems like a Robinson accident or two show up every week.
