C-GSQQ - Aircraft Aircraft Registration

The failure of ground personnel to obtain permission from airport management to conduct engine test runs; adequately monitor the area behind the B737 for traffic; and install barricades to prevent access behind the running airplane, which resulted in the accident pilot's loss of control during taxi due to an encounter with the jet blast. Contributing to the accident were the accident pilot's failure to detect that the B737 engines were running, and the airport management's failure to establish written standard operating procedures regarding engine runs.
