## Probable cause

THE STUDENT PILOT'S DELAYED FLARE AND IMPROPER BOUNCED LANDING RECOVERY TECHNIQUE WHICH RESULTED IN AN INADVERTENT PORPOISE AND A COLLISION WITH THE RUNWAY.  A FACTOR IN THE ACCIDENT WAS THE STUDENT'S LACK OF TOTAL EXPERIENCE.

## Sequence of events

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

- On ground/water encounter with terrain/water, landing - flare/touchdown
  - flare - delayed, pilot in command (cause)
  - recovery from bounced landing - inadequate, pilot in command (cause)
  - porpoise/pilot-induced oscillation - inadvertent, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)

## Analysis

ACCORDING TO A WRITTEN REPORT FILED BY THE OPERATOR, THE FLIGHT BEGAN AS A DUAL INSTRUCTIONAL FLIGHT TO LAKEPORT TO ENABLE THE PRIMARY STUDENT TO PRACTICE TAKEOFFS AND LANDINGS. AFTER SEVERAL TOUCH AND GO LANDINGS, THE INSTRUCTOR DECIDED TO LET THE STUDENT PERFORM HER FIRST SUPERVISED SOLO FLIGHT AND GOT OUT OF THE AIRCRAFT. ON THE FIRST SOLO TRAFFIC PATTERN, THE STUDENT WAS HIGH AND APPARENTLY FLARED LATE, RESULTING IN A HARD LANDING AND A BOUNCE. THE AIRCRAFT BOUNCED TWICE MORE AND THEN COLLIDED WITH THE RUNWAY NOSE FIRST.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
