The Transportation Safety Board is sending investigators to a scene in northern Alberta where a plane performing at a town fair disappeared and crashed, killing its pilot.

RCMP say two small planes were performing acrobatic manuevers for the Smith Fall Fair on Saturday when one of the planes disappeared.

The aircraft was found an hour later east of Smith, a hamlet 180 kilometres north of Edmonton.

Police said there was only one occupant in the plane at the time of the crash, and that person was pronounced dead at the scene. They said they would not be identifying the deceased.

Transportation Safety Board spokesman Alex Fournier said the plane was a Nanchang CJ-6, which is a propeller-driven military training aircraft built in China.

Fournier said two TSB investigators were being sent to the site and would arrive Sunday.

An online poster for the fair lists the Barry Pendrak Airshow among Saturday's attractions.

Reached by phone on Saturday evening, Barry Pendrak said he wouldn't be answering questions about the crash, but said the show was Transport Canada approved.

The show's Facebook account says the show is based in Smith.

J.D. Dennis, vice president of the Smith-Hondo Agricultural Society and a local resident, said that one pilot went down and did not survive the crash.

He said Barry Pendrak Airshows have performed at the fair before and "it's always been great."

Police have asked anyone who may have been recording video of the air show to contact them.
