Investigation Docket - National Transportation Safety Board:

Location: Roseburg, Oregon 
Accident Number: GAA19CA255
Date & Time: May 10, 2019, 13:25 Local
Registration: N107DM
Aircraft: Elmwood CHRISTAVIA MK I 
Aircraft Damage: Substantial
Defining Event: Loss of control on ground 
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Flight test


The pilot of the tailwheel-equipped airplane reported that he made a three-point landing, but during the landing roll, the airplane veered right. He added that his left rudder and brake application "was not fast enough to arrest the progressive turn rate." He then applied full power to regain directional control, but his corrective action was too slow, so he decided to go around. He then realized that the climb rate was too slow, so he decided to abort the takeoff. The airplane touched down and exited the right side of the runway and subsequently ground looped to the right, and the left wing struck the ground.

The left wing sustained substantial damage. 

The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control during landing, which resulted in a ground loop. 


Personnel issues Aircraft control - Pilot
Aircraft Directional control - Not attained/maintained

ROSEBURG, Oregon -- A small plane crashed at the Roseburg Regional Airport Friday afternoon.

The Federal Aviation Administration said a Christavia MK I flipped on its side. Roseburg police said they responded to the airport at about 1:30 p.m. 

Police said pilot Malcom Dayton, 63, of Roseburg, who owns the plane, was uninjured. They said Dayton told police he was in contact with the ground attempting to land when a cross wind pushed the plane into a grassy area. He said the wheel broke and the 2019 experimental plane was damaged from whipping around.

Roseburg fire officials said no one else was in the airplane at the time. The Roseburg Fire Department and Umpqua Valley Ambulance assisted at the scene.

The Federal Aviation Administration said they and the National Transportation Safety Board will investigate.

The Roseburg Regional Airport remained open.
