Probable cause

The pilot's failure to maintain airspeed after a total loss of engine power at takeoff, which resulted in a hard landing. Also causal was the pilot/owner/builder's improper installation of the magnetos which resulted in the engine power loss.

Findings · 3

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/owner/builder reported that at 30 to 50 feet above the runway in a steep climb after takeoff, the engine stopped producing power. The airplane "nosed over quickly" and landed hard on the nose wheel, bounced, and landed hard on the nose wheel again, collapsing it, and causing substantial damage to the firewall and airframe. Examination of the airplane's engine by an FAA airworthiness inspector revealed that both magnetos were improperly grounded at installation. The installation as found resulted in a degraded performance, and over time, resulted in a complete ignition failure and total loss of engine power.
