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 student pilot was attempting to land when the airplane's descent rate increased, resulting in a hard landing and a bounce. The airplane nosed over prior to the touchdown, allowing the propeller to strike the runway and causing the nose landing gear to buckle and collapse before the airplane skidded to a stop. The airplane sustained substantial damage to the firewall. A postaccident examination did not reveal any anomalies with the airplane that would have prevented normal operation.
