NTSB summary

HISTORY OF FLIGHT On April 3, 1999, about 2350 hours Pacific standard time, a Messerschmitt-Bolkow-Blohm (Mbb) BO-105CBS-4, N105HH, with the call sign Lifeguard 2, was en route to Pahrump, Nevada, when it collided with terrain and burned while maneuvering near Indian Springs, Nevada. The aircraft was destroyed and the certificated airline transport pilot and his two medical crewmembers received fatal injuries. The aircraft was operated as a positioning flight under 14 CFR Part 91 by Metro Aviation, Inc., when the accident occurred. The flight originated from Las Vegas, Nevada, about 2315 on April 3, 1999. Instrument meteorological conditions prevailed at the accident site and a company flight plan had been filed. The aircraft departed Valley Hospital Medical Center in Las Vegas after delivering a patient. The purpose of the flight was to reposition the aircraft at its home base at Hidden Hills Airport, Pahrump, Nevada. A motorist, who was westbound on U.S. highway 95 near the overpass at state highway 156, reported seeing a helicopter with a flashing strobe light flying over the highway in the same direction on the night of the accident. He estimated the aircraft's altitude at that time to be about 1,000 feet agl. He stated that the sky was overcast with freezing rain that turned into wet snow and then finally freezing sleet. Within a few minutes, the freezing precipitation had obscured the forward vision through his windshield. His windshield wipers were unable to remove the frozen accumulation and he was forced to roll down his driver's side window in order to obtain any

Probable cause

the pilot's decision to continue VFR flight in deteriorating IFR conditions resulting in spatial disorientation and subsequent loss of control.
