Narrative Report
On May 28, 1998 at 01:00 PM, North Platte - Kearney experienced a crash involving Cessna 414 Chancellor, operated by Silverhawk Security Specialists, with the event recorded near North Platte Nebraska.
The flight was categorized as executive/corporate/business and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.
3 people were known to be on board, 0 fatalities were recorded, 3 survivors were identified or estimated. This corresponds to an estimated fatality rate of 0.0%.
Crew on board: 1, crew fatalities: 0, passengers on board: 2, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is technical failure. The airplane had just taken off and was at approximately 300 agl when the right engine 'had a sudden and catastrophic failure.' The right propeller stopped spinning with the blades in the low-pitch position. The pilot initiated a right turn back toward the airport, but the airplane would not maintain altitude. The pilot rolled out of the turn, but the descent continued until the airplane struck the trees. Examination of the airplane's right engine revealed that the crankshaft was broken at the number 3 short cheek, just forward of the number two cylinder piston rod. The number two crankshaft bearing was broken and melted. The oil feed line to the number two bearing was blocked by a piece of the broken bearing. The Single Engine Climb Data table in the Cessna 414 Pilot's Operating Handbook indicates that an airplane weighing 5,680 pounds, with gear and flaps retracted and the inoperative propeller in feather, operating at a density altitude of 5,055 feet, will have a best climb indicated airspeed of 115 knots. The rate of climb will be 308 feet per minute.
Aircraft reference details include registration N888AA, MSN 414-0468, year of manufacture 1974.
