## Sequence of events

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

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

## Analysis

THE ACFT MADE A HARD LANDING WHILE ON A TRAINING FLT. ACCORDING TO THE INSTRUCTOR PLT, 'DURING THE LANDING FLARE, WE WERE DESCENDING VERY GRADUALLY AS THE AIRSPEED CONTINUED TO DISSIPATE.' LATE IN THE FLARE THE ANGLE OF ATTACK INDICATOR WAS APPROACHING THE STALL RANGE, THE ACFT STALLED AS EVIDENCED BY A SHARP & SUDDEN AIRFRAME BUFFET. ALMOST IMMEDIATELY THE MAIN GEAR CONTACTED THE RWY WITH THE ACFT IN A NOSE HIGH, WINGS LEVEL ATTITUDE. AT THE TIME OF THE INCIDENT, THE LEADING EDGE OF THE WINGS & TAIL STRUCTURE HAD CLEAR & RIME ICE ABT 1/8 IN THICK. THE TEMP WAS 24 DEG F.
