Aircraft: AMERICAN CHAMPION AIRCRAFT 7GCBC 
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

According to the pilot, the purpose of the flight was to practice wheel landings in the tailwheel equipped airplane. The third approach was normal, and the airplane touched down to the right of centerline of the runway. The pilot applied left rudder to maneuver the airplane onto the centerline and “inadvertently engaged” the toe brake, which resulted in a veer to the left. The pilot attempted to correct the turn; however, he “over corrected” and the airplane departed the right side of the runway into the grass. The airplane nosed over and came to rest inverted, which resulted in substantial damage to the fuselage and right wing. The pilot reported no preimpact 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 the landing roll. 

Findings

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

PLAINVILLE, Connecticut — A close call Thursday morning at Plainville's Robertson Airport.

Just after 11:30 a.m., a single-engine plane flipped over nose first after landing at Robertson Airport. The pilot, the only person in the plane, escaped serious injury.

"It appears that the single-engine plane, after landing, veered off to the right-hand side (of the runway) onto a grassy area and then flipped over onto its roof," said Chief Chris Vanghele of the Plainville Police Department.

But why remains a question Vanghele could not answer.

"It could be something with the brakes. We don't know," he said.

The lone occupant, according to sources, was 81-year-old pilot Frank Dworak.

"He was transported to the hospital, which seems right now to be a very minor injuries," Vanghele added.

And he noted that it does not appear the pilot suffered a medical event.

"He was conscious and he was alert and talking while he was being extricated from the plane," the Chief said.

The FAA has not responded to FOX61's request for the pilot's flight plan and Robertson Airport officials declined to comment when asked if the plane is based at Robertson.

"The plane itself was made safe by the fire department and mechanics here to ensure that there is nothing flammable and no issues during the investigation," Vanghele said. "The skid marks in the grass are probably only about 50 to 60 feet long and then at you know when it dove nose-first the propeller hit and then the plane flipped over onto its roof."

The airport was closed to air traffic for several hours. The plane was carted away by investigators.
