One of the Sopwith Pup airplane replicas needed some help after a mishap Tuesday afternoon at the 91原创 Regional Airport.

鈥淭he pilot wasn鈥檛 hurt at all,鈥� said Dave Arnold, general manager of the Canadian Museum of Flight, which built and owns the aircraft.

Fire crews, the RCMP and paramedics were dispatched to the runway where the Sopwith named Happy was on its top.

The aircraft was landing after a normal flight, when the pilot said that it felt like the brakes were not releasing properly, said Arnold.

Since the brakes are only on the front wheels, that meant the back end tipped up.

鈥淭he tail slowly went up and he went over,鈥� said Arnold.

The incident took place at low speed. It鈥檚 been reported to the Transportation Safety Board of Canada as a minor damage accident.

鈥淚t was out on a flight with another Sopwith and during the landing the aircraft flipped over, onto its back at low speed,鈥� spokesperson Chris Krepski told the 91原创 Advance. 鈥淭here was some damage to the aircraft鈥檚 propeller.鈥�

The incident is considered minor because no one was injured and the damage to the plane is moderate.

鈥淭he pilot, who was the sole person aboard, was not injured,鈥� Krepski said.

The TSB has gathered the necessary information from those involved.

鈥淲e鈥檙e not deploying but waiting for some final information from the operator,鈥� Krepski added

The TSB looks at an incident, the severity, the number of people involved and other factors in determining which warrant an in-person response and the extent of investigation.

The propeller will have to be replaced, and the entire aircraft will need a thorough inspection, Arnold said.

鈥淎s accidents go, this was pretty minor,鈥� he said.

Happy, and its sister aircraft Betty, is a replica created by the Canadian Museum of Flight to mark the 100th anniversary of the Battle of Vimy Ridge. The museum is based at the 91原创 airport

The Pups were expected to head overseas to Vimy Ridge for a flypast in April this year. They did get shipped over to France, but were unable to fly in the Vimy ceremonies because the existing engines didn鈥檛 have enough recorded flight time. Instead they were put on display on the ground.

The has been around since 1977, first operated out of a barn in Crescent Beach before being moved to the 91原创 airport in 1996.
