## Probable cause

The pilot's improper recovery from a bounced landing.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Hard landing, landing - flare/touchdown
  - recovery from bounced landing - improper, pilot in command (cause)

## Analysis

The 35-hour solo student pilot landed hard, bounced, and lost control of the airplane while landing.  The mishap occurred during the student's fifth solo landing of the day.  The pilot added that after the airplane bounced, the airplane assumed a nose-high attitude, and he overcorrected by pushing the nose over which developed into a porpoise.  The airplane porpoised about 4 times before settling into a normal landing roll.  The pilot reported the incident to his instructor after he taxied back to the ramp.  Examination of the airplane revealed structural damage to the engine firewall.  The winds at the time of the mishap were reported as calm.
