Aviation Accident Summary DEN04LA033

Santa Fe, NM, USA

Aircraft #1

N291LL

Aerospatiale AS 365 N-2

Analysis

The wind was from "270 degrees at 16 knots with gusts unknown" when the pilot landed on the runway. He then ground taxied towards a maintenance hangar. He described his ground taxi speed as "a fast walk pace." As the helicopter passed between two sets of hangars, "high velocity winds from the left (270 degrees)...lifted the left wheel off the ground." He applied left cyclic control and left tail rotor control that brought the helicopter off centerline to the left. He maneuvered the helicopter and focused on the same corner of the hangar "as I always did" when parking. "As soon as I was starting to use right pedal, the [main rotor] blades impacted the hangar door," and the "torque of the blades pulled the aircraft nose around into the hangar door, causing [the helicopter] to land on its left side."
