What happened
On June 7, 2019, a Beechcraft C-90A, registration LV-WXC, was performing a general aviation ferry flight from the El Gringo private aerodrome in Charata, Chaco, toward La Plata. As the aircraft reached approximately 80 knots during its takeoff roll, it struck a dog on the runway. The impact caused the right main landing gear and its shock strut to detach from the aircraft. Following the strike, the right wing dropped, and the right engine experienced a sudden stoppage, with the propeller making contact with the ground. The pilot attempted to shut down the engines, but the aircraft lost directional control, veered to the right, and exited the runway. The aircraft traveled approximately 151 meters before performing a 180-degree turn and coming to a halt. There were no fatalities or injuries to the crew or passengers, though the aircraft sustained light damage.
The investigation
Investigators examined the wreckage and the airfield environment. The inspection confirmed the separation of the right main gear and significant damage to the right propeller. Interviews with the pilot established that the animal strike occurred near the rotation speed, leaving insufficient time for evasive maneuvers. The investigation also focused on the aerodrome's operational conditions. It was discovered that the dogs involved in the incident belonged to the aerodrome owners and were frequently allowed to roam freely within the operational areas. Furthermore, the investigation found that the runway dimensions had been altered without authorization. While the certified length was 530 meters, the actual length was approximately 1,530 meters. This extension placed the runway in close proximity to unauthorized obstacles, including a shed and a residential house, violating established safety regulations regarding obstacle clearance.
Findings
- The primary cause of the accident was the collision with a dog during the takeoff phase.
- The presence of unrestrained domestic animals in the operational areas was a routine occurrence at the aerodrome.
- The aircraft's landing gear assembly was destroyed by the impact, leading to the loss of ground control.
- The aerodrome was operating with uncertified runway modifications that did not comply with current aeronautical regulations.
Safety action
- The aerodrome owner must ensure that all aircraft operational areas remain free of obstacles as required by regulation.
- The owner is required to coordinate with the aeronautical authority to inspect and formally certify any runway modifications.
- Measures must be implemented to prevent domestic and wild animals from entering the aircraft operational zones.
