Location: Larchwood, IA
Accident Number: CEN18LA025
Date & Time: 11/06/2017, 1310 CST
Registration: N7085M
Aircraft: ROBINSON HELICOPTER R44
Aircraft Damage: Substantial
Defining Event: Controlled flight into terr/obj (CFIT)
Injuries: 2 Serious
Flight Conducted Under: Part 91: General Aviation - Aerial Observation 

On November 6, 2017, about 1310 central standard time, a Robinson Helicopter R44 helicopter, N7085M, was substantially damaged when it impacted powerlines and then terrain 4.5 miles south of Larchwood, Iowa. The commercial pilot and passenger sustained serious injuries. The aerial observation flight was conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no Federal Aviation Administration (FAA) flight plan had been filed for the flight. The local flight departed about 1300.

According to the passenger and witnesses on the ground, the helicopter was assisting in locating and herding 300 cattle that were loose in the area. The helicopter was assisting the ground team to push the cattle towards an open gate directly beneath powerlines. Witnesses on the ground observed the helicopter hovering and as it started to turn, the "tail" of the helicopter hit the powerlines. The helicopter descended to the ground and came to rest on its right side in a corn field. Several witnesses and the passenger stated that the helicopter looked and sounded normal prior to the impact.

A video of the accident taken by another witness on the ground showed the helicopter maneuvering near the powerlines, with the nose of the helicopter facing away from the powerlines. The tail of the helicopter impacted the powerlines, followed by the main rotor blades. The helicopter rotated once before impacting the ground.

According to a FAA inspector who responded to the accident, the tailboom separated from the fuselage and both main rotors were substantially damaged. An examination of the helicopter, engine, and remaining systems revealed no mechanical anomalies that would have precluded normal operations.

An official weather observation taken 18 miles northwest of the accident site reported the weather as wind 060° at 7 knots, visibility 1.5 miles in light snow, overcast skies at 2,300 ft above ground level, temperature -1° C, dewpoint temperature -4°C, and an altimeter of 30.26 inches of mercury. The witnesses on the ground at the accident site characterized the weather as overcast, windy, unlimited visibility, and no precipitation.

Inwood, I.A. - Two people are in the hospital with serious injuries Monday, following a helicopter crash in northwest Iowa. The Lyon County Sheriff's Office confirmed to KSFY that the helicopter went down around 1:20 Monday afternoon in a field near West Lyon High School in Inwood

Authorities put up crime scene tape and blocked off the area. Lyon County Sheriff Stewart VanderStoep said the helicopter was helping crews on the ground search for 300 head of cattle on the loose in the area when it hit a power line and crashed. Sheriff VanderStoep said the two men in the helicopter have serious injuries. He said the helicopter belonged to a private agency and was hired by the farmer to search for the cattle.

“We do have cattle loose quite a bit. 300 at the same time, that's pretty rare, but we do go probably every two weeks, we'll get a call that there's some cattle out. Usually we figure out who they belong to by calling farmers in the area, Sheriff VanderStoep said.

The Federal Aviation Administration is scheduled to arrive at the scene of the crash Tuesday morning. The Lyon county sheriff said he hopes to have more information after that. Sheriff VanderStoep said the city of Rock Rapids was without power for about 10 minutes following the crash.

According to Rock Rapids Utility Manager Jim Hoye, it was an L & O Power Coop line that feeds Rock Rapids. He says Rock Rapids has two feeds from L & O, and he says it’s possible that L & O switched feeds to get the power back on in Rock Rapids.
