Event Description
Under dark night conditions, a check pilot was conducting a captain proficiency check on another company pilot (PIC). After a full-stop landing on runway 25, the takeoff checklist was recited. The PIC commenced takeoff on runway 07. Shortly after liftoff, the check pilot simulated a V1 engine cut. The PIC was unable to accelerate to V2, climb, or maintain directional control. The aircraft leveled off, airspeed decayed, and the aircraft drifted to the right. The check captain failed to take control or terminate the simulation as the situation deteriorated. The aircraft collided with an ILS glideslope tower marked by red obstruction lights. Following the collision, the right wingtip and aileron separated, causing a loss of control. The aircraft then impacted the ground and slid to a stop.
Configuration and Performance
The takeoff flap position should have been 1/4. However, both flaps were found near the 1/2 flap extended position, with the handle in the 1/2 flap detent. Performance charts indicate the aircraft is capable of reaching V2 at 50 feet altitude within 6,500 feet of roll, followed by a climb rate of +575 fpm (Vyse) at the accident weight.
Findings
The official findings list three occurrences:
- Occurrence #1 (loss of engine power during takeoff initial climb): Inadequate preflight planning by the PIC; flaps not raised; inattentive checklist use by the PIC; simulated emergency procedure by the check pilot; proper climb rate not possible; directional control not possible; inadequate supervision by the check pilot.
- Occurrence #2 (loss of control in flight): Collision with a marked tower; wing and wingtip separation; partial loss of aileron.
- Occurrence #3 (in-flight collision with terrain): Uncontrolled descent.
