The Springbank Air Training College Piper PA 34-200T Seneca II, registered C-GCCM, departed Calgary Springbank (CYBW) runway 17 on a final training flight prior to the student's multi-engine rating flight test. There was an instructor and student on board. The aircraft did not climb above 250 feet nor accelerate while on the runway heading. The aircraft rolled to the left entering a steep left turn and collided with terrain. There was a post-crash fire, and the two occupants sustained fatal injuries, the aircraft was destroyed.
The student with 175 hours (6 on type) of flight experience was at the controls. The flight instructor had a total of 2,150 hours, of which 141.5 on type.

Findings as to causes and contributing factors:
1. It is likely that a left-engine failure on takeoff was being simulated. It appears that, during this exercise, the maximum power was not set on the right engine to enable the aircraft to achieve the 1-engine-inoperative best rate-of-climb airspeed (VYSE) and a positive rate of climb. The investigation could not determine why maximum power would not have been set.
2. For unknown reasons, the airspeed decayed below the intentional 1-engine-inoperative speed (VSSE) to the minimum control airspeed (VMC) and the aircraft departed controlled flight and collided with terrain.
3. The asymmetric power condition with the simulated left-engine failure at VMC would have resulted in a VMC roll at a height from which the pilots would have been unable to recover before impact with the terrain.

Findings as to risk:
1. If simulated engine failures are conducted at low altitudes, there is a risk that pilots will be unable to recover in the event of a loss of control.
