Probable cause

A ruptured fuel line, which resulted in fuel starvation to the engine and a total loss of engine power.

Findings · 1

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 gyrocopter reported that he departed with full fuel tanks for a local flight. While flying along a coastline, the engine lost power, and the pilot navigated to complete a forced landing on a beach. During the landing rollout, the nose wheel dug into soft sand and the gyrocopter rolled over onto its left side, which resulted in substantial damage to the main rotor and empennage. Postaccident examination of the gyrocopter’s engine revealed that a rubber fuel supply line was ruptured. Given this information, it is likely that the fuel leak starved the engine of fuel, which resulted in a total loss of engine power.
