NTSB Identification: WPR12LA317
14 CFR Part 91: General Aviation
Accident occurred Saturday, July 21, 2012 in Bridger, MT
Probable Cause Approval Date: 03/07/2014
Aircraft: HEREM DR-107, registration: N58GH
Injuries: 1 Serious.
NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
A witness stated that the airplane’s takeoff and initial climb appeared normal; however, when the airplane reached midfield, it rolled left. The airplane continued to roll, and it then pitched up. The airplane subsequently returned to a nearly level pitch attitude and then pitched down and collided with terrain. The pilot reported that he did not intentionally roll the airplane after takeoff; however, he was unable to recall specific details regarding the sequence of events and the reason for the abrupt maneuver after takeoff. A postaccident examination of the airframe, including the flight controls and engine, revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s failure to maintain airplane control while maneuvering after takeoff.
On July 21, 2012, about 0915 mountain daylight time, an experimental amateur-built Herem DR-107 airplane, N58GH, collided with terrain while maneuvering after takeoff from the Bridger Municipal Airport (6S1), Bridger, Montana. The commercial pilot, the sole occupant of the airplane, was seriously injured. The airplane impacted terrain in a tail-low attitude and sustained substantial damage to both wings and empennage. The airplane was registered to, and operated by, the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed and no flight plan was filed for the cross-county flight; the pilot's planned destination was Billings, Montana.
The pilot was participating in a general aviation fly-in at the Bridger Municipal Airport. He arrived earlier in the day, and the accident flight was the return leg to Billings. A witness stated the pilot's takeoff and initial climb appeared normal; however, when the airplane reached midfield it rolled left. The airplane continued to roll, and about 270-degrees through the second roll the airplane pitched up. The airplane returned to a nearly level pitch attitude and then pitched down and subsequently collided with terrain.
The pilot reported that he did not intentionally roll the airplane after takeoff; however, he was unable to recall specific details regarding the sequence of events leading up to the accident.
Examination of the wreckage at the accident site by a Federal Aviation Administration (FAA) inspector revealed that the airplane came to rest near the departure runway and sustained substantial damage to the fuselage and both wings. Examination of the airframe, engine and flight control system components revealed no evidence of a preimpact mechanical malfunction or failure that would have precluded normal operation.
The NTSB Pilot/Operator Accident Report (form 6120), submitted by the pilot, he indicated that there were no mechanical malfunctions of failures with the airplane.

On July 21, 2012, about 0930 mountain daylight time, an experimental amateur-built Herem DR-107 airplane, N58GH, collided with terrain while maneuvering after takeoff from the Bridger Municipal Airport (6S1), Bridger, Montana. The commercial pilot, the sole occupant of the airplane, was seriously injured. The airplane impacted terrain in a tail-low attitude and sustained substantial damage to both wings and empennage. The airplane was registered to the pilot, and operated under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed and no flight plan was filed for the cross-county flight; the pilot’s planned destination was Billings, Montana.
A witness stated that he observed the airplane takeoff. He reported that just after the airplane became airborne it rolled as if the pilot was doing a “barrel roll.” Shortly thereafter the airplane collided with terrain beyond the departure end of the runway.
The pilot was participating in a general aviation fly-in at the Bridger Municipal Airport.
A plane flown by a Billings pilot crash after take off in Bridger, MT on Saturday.
A Billings pilot was injured on Saturday morning when his homemade airplane crashed as he attempted an acrobatic maneuver at the Bridger Municipal Airport.
Gary Herem, 60, crashed in his 2011 One Design single-seat acrobatic aircraft after takeoff, said Bridger Police Chief Mike Buechler. The crash happened just after 9:15 a.m.
Herem, a veteran pilot, was at the airport as part of a fly-in that happens during the annual Bridger Days celebration, which started Friday night and will end on Sunday. A variety of aircraft, including homemade and nostalgic planes, and helicopters, fly in early Saturday, Buechler said.
Visitors get a chance to look around at the aircraft before the pilots fly out. About 100 people were at the airport when the crash happened, Buechler said.
Witnesses said Herem apparently attempted a barrel roll or a half-barrel roll just after he lifted off the runway and his plane hit the ground.
The Help Flight helicopter from St. Vincent Healthcare was on hand for the event, Buechler said. Within a matter of minutes, the medical team strapped Herem, who was conscious, into the helicopter and transported him to St. Vincent.
On Saturday night, a spokeswoman for the hospital said Herem is in fair condition.
