Location:NE of Brookhaven Airport (KHWV), Shirley, NY -   United States of America
Phase: Landing
Departure airport:Shirley, NY (HWV)

Investigating agency: NTSB
The private pilot reported that he was conducting touch-and-go landings and that, while on final approach, the experimental, light sport airplane encountered a downdraft, and the engine lost total power. The pilot was unable to restart the engine or glide the airplane to the runway, and it impacted trees.
The engine was test run successfully several times, and no anomalies were noted. The engine's choke control was located near the throttle lever. During the test runs, the engine lost total power if the choke control was moved about halfway (1 inch). It is likely that the pilot's hand was on the throttle lever and that it inadvertently bumped the choke control during the downdraft encounter, which resulted in a total loss of engine power.

Probable Cause: The pilot's inadvertent activation of the engine's choke control during a downdraft encounter, which resulted in a total loss of engine power.
