A pilot took off without performing terrain clearance calculations. Faced with gusty winds, turbulence, downdrafts, and high density altitude, the pilot made a precautionary landing in a field. During the landing roll, one main gear collapsed, causing substantial damage.

Incident Overview

A pilot initiated a takeoff without first performing calculations to determine whether the aircraft could out-climb surrounding terrain under the existing ambient conditions. The departure was conducted in an environment characterized by gusty winds, turbulence, downdrafts, and high density altitude. Shortly after becoming airborne, it became apparent that the aircraft might sink into the unfavorable terrain along the departure route.

Pilot Action

In response to the deteriorating climb performance and the risk of terrain contact, the pilot elected to make a precautionary landing in an open field. The landing was carried out on rough and uneven terrain.

Landing and Damage

During the landing roll on the rough/uneven surface, one of the main landing gear collapsed. The aircraft sustained substantial damage as a result of the gear collapse and the subsequent ground contact.

Conditions

Weather conditions at the time were reported as gusty winds, turbulence, and downdrafts. The high density altitude likely degraded aircraft performance, contributing to the pilot's decision to land off-airport.
