## Probable cause

The student pilot's failure to maintain an appropriate glide path during approach. Contributing to the accident was the student pilot's decision to continue the approach instead of going around.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Performance/control parameters: descent/approach/glide path](https://openairdocs.org/ntsb-findings/01062040): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Cessna 172S, 18 cases](https://openairdocs.org/ntsb-findings/01062040/cases.md?model=2072439), [All aircraft, 809 cases](https://openairdocs.org/ntsb-findings/01062040/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing-flare/touchdown: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [Cessna 172S, 102 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=2072439), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

The student pilot was practicing touch-and-go landings. During the first approach she felt that her approach was too high, so she pitched down slightly, leveled off, and landed on the main landing gear. After landing, the airplane porpoised twice and then landed flat and hard. The pilot taxied back to the hangar and had the airplane examined for damage. None was found, so she took off again and continued her training. Sometime after the flight the firewall was found buckled. The student pilot's recommendation for preventing the accident was to add power and go around.
