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)
- Hard landing, landing - flare/touchdown
  - wing - ice (contributing factor)
  - airspeed - not maintained, pilot in command (cause)

## Analysis

AFTER BREAKING OUT OF THE CLOUDS THE PILOT DESCENDED WITH FULL FLAPS AT 110 TO 115 KNOTS. HE BEGAN TO FLARE AND NOTICED SOME MUSHINESS AND THAT THE AIRSPEED HAD DROPPED TO 100 KNOTS. THE AIRCRAFT STALLED FROM ABOUT 15 FEET.

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.
