Brewster, WA, USA

Aircraft #1

N9043N

SIKORSKY S-58B

Analysis

As the helicopter lifted into a hover, the manifold pressure gauge indicated a significant increase and the pilot smelled smoke. The pilot set the helicopter back onto the ramp and observed smoke rolling up the side of the fuselage. He egressed the helicopter rapidly and noticed fire around the engine compartment. The magnesium-constructed airframe was subsequently consumed by fire; the origin of the fire could not be determined.
