A fatal crash south of Calgary last August might have been partly due to "multitasking" by the pilot, according to a Transportation Safety Board report.
The pilot, who was flying solo in a Cessna 172M, went into a spin and hit the ground while doing a pipeline inspection at the Chain Lakes Reservoir near Claresholm.
He was killed in the crash.
The reason the pilot lost control remains undetermined.
However, investigators noted the crash happened while he was manoeuvring to take photographs.
"The TSB noted in its report that there is an increased risk of loss of control when single-pilot, low-level aerial inspections include additional tasks beyond flying the aircraft, such as photography," the board said in a release.
