Grand Canyon West - Las Vegas

On June 19, 1992 at 02:05 PM, Grand Canyon West - Las Vegas experienced a crash involving Cessna 402, operated by Adventure Airlines, with the event recorded near Grand Canyon West Arizona.

The flight was categorized as charter/taxi (non scheduled revenue flight) and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.

10 people were known to be on board, 10 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.

Crew on board: 1, crew fatalities: 1, passengers on board: 9, passenger fatalities: 9, other fatalities: 0.

The listed crash cause is technical failure. Pilot began takeoff on a 5,200 feet dirt runway (upslope to the south, elevation 4,775 feet) with wind from the south at 18-20 knots, density altitude about 7,250 feet. Witnesses observed the aircraft taking off, with the landing gear retracting as it passed their position. Soon thereafter, the pilot transmitted he had 'a problem.' Aircraft was then seen about 200-300 feet agl in right turn, which progressed into a dive. Aircraft impacted in flat attitude 1/2 mile south of runway 17. Passenger video tapes revealed props went out of sync about 6 seconds after takeoff. About 15 seconds later, right prop slowed until blades could be seen turning. Video showed one engine fuel flow at about 90 gph, other engine at minimum setting (about 3 psi), 5° increase in pitch attitude. Exam revealed right engine driven fuel pump drive coupling was scored and only partially engaged. SB ME88-3 complied with; auxiliary fuel pump switches found in low position. Right propeller blades found at fine pitch, lacking rotational damage. Landing gear found up, but unlocked; flaps extended 15°. Emergency procedure training did not replicate high density altitude and max gross weight performance. All 10 occupants were killed.

Aircraft reference details include registration N2715X, MSN 402C-0215, year of manufacture 1979.

Geospatial coordinates for this crash are approximately 35.9857°, -113.8207°.
