Probable cause

The airplane’s encounter with low-level wind shear during takeoff, which resulted in an off-airport landing.

NTSB narrative

The flight instructor and student pilot were departing on an instructional cross-country flight when, just after takeoff, the airplane encountered wind and turbulence. The instructor had difficulty maintaining altitude and elected to perform an off-airport precautionary landing, during which the right wing sustained substantial damage. A weather study revealed conditions conducive to low-level wind shear and turbulence at the accident site at the time of the accident. Although the instructor had received an abbreviated weather briefing before departure, the briefing did not advise of the potential for low-level wind shear. It is likely that the encounter with wind shear during departure made it difficult for the airplane to maintain altitude.
