Pilot Aborts Downwind Takeoff, Aircraft Flips and Burns (N9816X)

Agua Dulce, CA, US

On January 6, 1990, a Cessna 185 (registration N9816X) was involved in an aviation accident near Agua Dulce, CA. Investigators recorded the probable cause as: The pilot's decision to attempt a takeoff in a tailwind without obtaining a weather briefing, which resulted in a loss of control during the aborted takeoff roll. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot attempted a takeoff in a tailwind without a weather briefing. The aircraft aborted the run, lost control, flipped over, and was destroyed by fire.

What happened

The pilot initiated a takeoff attempt under unfavorable wind conditions, specifically choosing to depart into a tailwind rather than into the wind. Prior to the flight, the pilot failed to obtain a weather briefing for the local area, missing critical information regarding wind direction and speed. During the takeoff roll, the aircraft departed downwind, which likely contributed to insufficient airspeed or control effectiveness. The pilot subsequently aborted the takeoff while the aircraft was still on the ground. During this abort maneuver, the pilot lost control of the aircraft. The loss of control resulted in the aircraft flipping over onto its back or side. Following the rollover, a fire broke out within the wreckage. The fire caused extensive damage to the airframe and systems, leading to the total destruction of the aircraft.

The investigation

Investigators examined the wreckage site and the remaining components of the aircraft to determine the sequence of events and the extent of the damage. The physical evidence confirmed that the aircraft had flipped over and sustained catastrophic structural failure due to the impact and subsequent fire. Investigators also looked into the pre-flight actions taken by the pilot, specifically regarding engine security procedures before leaving the aircraft. However, it was not determined if the pilot secured the aircraft engine prior to his departure from the aircraft.

Findings

The primary factors contributing to this accident were the decision to take off in a tailwind and the failure to obtain a pre-flight weather briefing. Taking off downwind increases ground speed required for lift-off and reduces safety margins, particularly if the pilot is not fully aware of wind conditions. The loss of control during the aborted takeoff phase led directly to the rollover and fire. The destruction of the aircraft was total, with no survivors reported in this account.

Safety message

Pilots should always obtain a complete weather briefing before flight to understand current and forecasted conditions, including wind direction. Takeoffs should generally be conducted into the wind to maximize performance and control authority. Aborting a takeoff is a critical decision that requires precise control inputs; pilots must be trained to handle high-speed aborts safely.

Probable cause

The pilot's decision to attempt a takeoff in a tailwind without obtaining a weather briefing, which resulted in a loss of control during the aborted takeoff roll.
