Narrative Report
On March 22, 2010 at 10:09 AM, Darwin - Darwin experienced a crash involving Embraer EMB-120 Brasília, operated by Airnorth Regional - RegionalLink, with the event recorded near Darwin Northern Territory.
The flight was categorized as training and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.
2 people were known to be on board, 2 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 2, crew fatalities: 2, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. Aircraft crashed moments after takeoff from runway 29 at Darwin Airport, Northern Territory, fatally injuring both pilots. The flight was for the purpose of revalidating the command instrument rating of the pilot under check and was under the command of a training and checking captain, who occupied the copilot’s seat. The takeoff included a simulated engine failure. Data from the aircraft’s flight recorders was used to establish the circumstances leading to the accident and showed that the pilot in command (PIC) retarded the left power lever to flight idle to simulate an engine failure. That introduced a simulated failure of the left engine and propeller autofeathering system. The increased drag from the ‘windmilling’ propeller increased the control forces required to maintain the aircraft’s flightpath. The pilot under check allowed the speed to decrease and the aircraft to bank toward the inoperative engine. Additionally, he increased power on the right engine, and engaged the yaw damper in an attempt to stabilize the aircraft’s flight. Those actions increased his workload and made control of the aircraft more difficult. The PIC did not restore power to the left engine to discontinue the manoeuvre. The few seconds available before the aircraft became uncontrollable were insufficient to allow ‘trouble shooting’ and deliberation before resolving the situation.
Aircraft reference details include registration VH-ANB, MSN 120-116, year of manufacture 1988.
Geospatial coordinates for this crash are approximately -12.4124°, 130.8357°.
