Fatal crash of Swiss-registered Cessna 421C at El Questro airstrip

Casualties unknown • El Questro Station, CH

A twin-engine Cessna 421C crashed into trees during takeoff at an Australian airstrip, resulting in two fatalities.

What happened

On 30 August 2004, a Cessna 421C Golden Eagle, registered HB-LRW, crashed shortly after departing runway 32 at the El Questro Aircraft Landing Area in Western Australia. The aircraft was being flown on a non-commercial pleasure flight as part of a delivery journey from Switzerland to Broome.

Witnesses at the airfield observed the pilot performing a pre-flight inspection and engine run-up checks. During the start-up process, the pilot struggled to start the left engine before successfully starting both. As the aircraft commenced its takeoff roll, observers noted the engines sounded normal and the aircraft accelerated briskly. However, shortly after lifting off from the runway, the aircraft banked to the left at an angle of approximately 10 to 15 degrees and drifted off the runway centerline. The aircraft struck trees located along the side of the runway and impacted the ground. The impact and subsequent post-impact fire destroyed the aircraft, and both the pilot and the sole passenger sustained fatal injuries.

The investigation

The investigation examined the aircraft's maintenance history, the pilot's experience, and the environmental conditions at the time of the accident. While the aircraft had undergone several repairs and component replacements during its transit from Switzerland—including engine work in Cyprus and hydraulic repairs in the UAE—the investigation found no evidence of mechanical failure. The aircraft's weight and center of gravity were estimated to be within safe operating limits, and the engines were delivering comparable power at the time of impact.

Investigators also reviewed the pilot's credentials, noting significant experience in the Cessna 420 series and a valid medical certificate. Meteorological data indicated calm conditions with no significant wind or thermal activity, such as dust devils, that could have disrupted the flight path.

Findings

  • The aircraft was operating within its weight and balance limits.
  • There was no evidence of engine failure, mechanical anomaly, or aerodynamic stall.
  • The proximity of trees to the left side of the runway left the pilot with very little margin for error.
  • The investigation could not rule out that the pilot may have been momentarily distracted during the critical moments of lift-off, leading to an unintended left bank and drift that could not be corrected before impact.

Probable cause

The aircraft developed an unintended left bank and drifted off the runway centerline immediately after takeoff, likely due to a momentary pilot distraction, leaving insufficient time to avoid the nearby trees.
