Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the airplane reported that, during the preflight engine runup, he diverted his attention to a phone call and failed to switch the fuel selector to a fuel tank with adequate fuel. During the initial climb, the engine experienced a complete loss of power, and the pilot performed a forced landing in an agricultural field. The airplane sustained substantial damage to both wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
