What happened
During the initial climb phase following departure from runway 11 at Monterrey-Del Norte Airport, a single-engine airplane experienced a sudden loss of altitude. The aircraft descended toward a highway situated beyond the end of the runway. While the flight path took the plane over the motorway, the aircraft did not make contact with any vehicles traveling on the road.
After passing over the highway, the plane impacted a field located approximately 15 meters below the level of the motorway. The pilot, who was the only person on board at the time of the accident, sustained serious injuries. The impact resulted in the aircraft being damaged beyond repair.
Findings
No specific technical cause for the loss of altitude was provided in the initial report, though the sequence of events indicates the descent occurred immediately after takeoff.
