## Probable cause

FAILURE OF THE PILOT IN COMMAND TO MAINTAIN AN AIRSPEED ABOVE STALL DURING A LANDING FLARE.

## Sequence of events

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

- In flight encounter with weather, approach - faf/outer marker to threshold (ifr)
  - weather condition - icing conditions (contributing factor)
- Loss of control - in flight, landing - flare/touchdown
  - airspeed(vs) - not maintained, pilot in command (cause)
- Hard landing, landing - flare/touchdown

## Analysis

THE PILOT REPORTED THE AIRPLANE STARTED ACCUMULATING STRUCTURAL ICE AFTER ENTERING CLOUDS DURING AN INSTRUMENT APPROACH.  HE REPORTED HE FLEW THE APPROACH AT A HIGHER THAN NORMAL AIRSPEED.  AS THE PILOT FLARED FOR TOUCHDOWN THE AIRPLANE SHUDDERED, FELL, AND LANDED HARD, LEFT MAIN LANDING GEAR FIRST.

## 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.
