A loose fuel line caused a light plane to crash in Trenton, N.S., in January, according to a report from the Transportation Safety Board.

The pilot, John Brewer of P.E.I., and a passenger were not seriously injured in the Jan. 18 crash. The Cessna 177 had just undergone maintenance at the Trenton airport and taken off for a test flight when it ran into trouble.

"In looking at the aircraft we found that there was a loose fuel line that would lead to inaccurate fuel metering and loss of fuel pressure to the engine," Mike Cunningham, the regional manager for air investigations for the Transportation Safety Board, told CBC News on Wednesday.

"Shortly after take off the pilot reported that he was having engine problems and was losing engine power. The engine RPM was fluctuating and he couldn't maintain altitude. So they wound up descending down into a stand of alders and small birch trees."

The report does not place blame. The information has been given to the plane's owner and the maintenance company.
