Overweight Cirrus SR22T crashes after runway excursion in Colombia

Casualties unknown • Orocué, CO

A Cirrus SR22T G3 failed to reach rotation speed during takeoff at Savanna Aerodrome, resulting in a collision with a tree and significant structural damage.

What happened

On October 20, 2024, at approximately 15:55 local time, a Cirrus SR22T G3, registration HK5259, was attempting a takeoff from Savanna Aerodrome in Orocué, Casanare, Colombia. The aircraft was scheduled for a private flight to Guaymaral.

During the takeoff roll on runway 24, the pilot attempted a maximum performance takeoff. As the aircraft approached the end of the runway, the pilot realized the aircraft had not reached the necessary rotation speed. An attempt to abort the takeoff was not possible. The aircraft exited the grass runway and, approximately 90 meters beyond the threshold, struck a tree with its right wing. The impact caused the aircraft to lose control, leading to a rollover and longitudinal rotation. The impact resulted in the separation of the left wing and the nose gear.

All 5 occupants (the pilot and four passengers) were able to evacuate the aircraft safely without injuries.

The investigation

The GRIAA investigation focused on the aircraft's performance and weight calculations. Investigators examined the aircraft's weight and balance records, the runway conditions, and the aircraft's maintenance status.

While the aircraft's engine and components showed no evidence of prior failure or fluid leaks, the investigation scrutinized the takeoff parameters. The runway at Savanna Aerodrome is a grass surface measuring 850 meters in length and 20 meters in width. Investigators also noted the condition of the tires, observing that the main tires were smooth, which can reduce friction and affect acceleration.

Findings

  • The primary cause of the accident was a runway excursion and collision with an obstacle caused by the aircraft exceeding its maximum takeoff weight.
  • Calculations revealed the aircraft was approximately 170 lbs over its established weight limits for the flight.
  • The takeoff weight was calculated at 3,562 lbs, exceeding the manufacturer's limit.
  • There was a failure to perform an adequate weight and balance analysis or a sufficient risk assessment regarding the takeoff weight and the available runway length.
  • The use of a grass runway increased rolling resistance, further impacting the required takeoff distance.

Probable cause

The aircraft failed to reach rotation speed because it was operating significantly above its maximum allowable takeoff weight, leading to an insufficient takeoff roll and subsequent runway excursion.
