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 reported that while landing she applied aft pressure on the control stick to flair the airplane and lost sight of the runway seeing only the nose of the airplane. She reduced pressure on the control stick and the passenger said "stick forward". The pilot stated that she didn't know how far forward she moved the control stick. The airplane subsequently impacted the runway and nosed down before settling back onto the landing gear. The airplane sustained damage to the propeller, cowl, landing gear and firewall.
