## Probable cause

THE PILOT-IN-COMMAND'S IMPROPER LANDING FLARE, WHICH RESULTED IN THE AIRCRAFT BOUNCING AND ENTERING A PORPOISE MANEUVER. CONTRIBUTING TO THE ACCIDENT WAS HIS FAILURE TO RECOVER FROM THE BOUNCED LANDING AND PERFORM A GO-AROUND.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - flare - improper, pilot in command (cause)
  - porpoise/pilot-induced oscillation - inadvertent, pilot in command (cause)
  - recovery from bounced landing - not performed, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
- Nose gear collapsed, landing - flare/touchdown
  - landing gear,nose gear - overload

## Analysis

THE PILOT STATED THAT THE AIRCRAFT FLOATED DURING THE LANDING FLARE AND HE LOWERED THE NOSE SLIGHTLY. THE NOSE LANDING GEAR CONTACTED THE RUNWAY AND THE AIRCRAFT BEGAN TO PORPOISE WITH THE NOSE GEAR CONTACTING THE RUNWAY EACH TIME. ON THE THIRD PORPOISE THE NOSE LANDING GEAR COLLAPSED AND THE AIRCRAFT SLID TO A STOP.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
