On July 26, 1993, a Cessna 310H (registration N310HJ) operated by Yehiem Konski was involved in an aviation accident near Lancaster, CA. Investigators recorded the probable cause as: the pilot's improper in-flight planning/decision and his failure to maintain the minimum control airspeed which progressed to an inadverent stall/spin. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A flight with 4 hours of fuel for a 2-hour trip ended in a crash after engines sputtered, a spin, and subsequent power recovery. No fuel was found in the tanks or spillage.
Flight and Communication
The flight departed with approximately 4.0 hours of fuel for a planned destination flight of 2.0 hours. The investigation did not determine if the flight landed at any other airport before the accident. When the flight was near the accident site, about 4 hours after departure, the pilot contacted the airport control tower and requested and received landing instructions. There were no further communications between the flight and the control tower.
Witness Accounts
Ground witnesses reported that the airplane's engines began to sputter, followed by the aircraft entering into a spin. During the spin, both engines began to develop power, which continued until impact.
Wreckage Examination
Examination of the wreckage disclosed evidence of power being developed at impact and that the left main fuel selector valve was selected to the crossfeed position. There was no evidence of any fuel in the fuel tanks or fuel spillage.
