## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - flight/nav instruments,airspeed indicator - false indication (contributing factor)
  - airspeed(vso) - not maintained, pilot in command (cause)
  - raising of flaps - premature, pilot in command (contributing factor)
  - aborted landing - not performed, pilot in command (cause)
- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (contributing factor)
  - recovery from bounced landing - improper, pilot in command (contributing factor)
- Nose gear collapsed, landing - roll

## Analysis

THE PILOT STATED THAT THE APPROACH SPEED WAS FASTER THAN NORMAL DUE TO ERRONEOUS AIRSPEED INDICATIONS. THE AIRCRAFT FLOATED UPON FLARING AND THE PILOT RAISED THE FLAPS. HE STATES THAT THE AIRCRAFT LOST LIFT, BOUNCED AFTER A HARD LANDING AND SUBSEQUENTLY LANDED ON ITS NOSE GEAR, COLLAPSING IT. HE FURTHER STATES THAT THE AIRSTRIP IS A ONE-WAY PROPOSITION WITH LITTLE MARGIN FOR ERROR.
