Analysis

The pilot stated to FAA inspectors that he ran out of fuel while on a cross-country flight and he initiated a forced landing into a field about a mile from his final destination. He noted that he had approximately 12 gallons of fuel on board when he departed, and that he had overflown a planned intermediate stop. When he realized he would have to make an off-airport landing, he selected a hay field about a mile north of the airport, touched down and got into some tall grass. The airplane nosed over onto its back, sustaining substantial damage.
