## Probable cause

1) THE PILOTS FAILURE TO COMPENSATE FOR WINDS DURING THE LANDING SEQUENCE, 2) THE IMPROPER USE OF THE FLIGHT CONTROLS BY NOT MAINTAINING DIRECTIONAL CONTROL OF THE AIRCRAFT,AND 3) THE PILOTS FAILURE TO MAINTAIN AN ADEQUATE AIRSPEED DURING THE LANDING PHASE WHICH RESULTED IN A STALL.

## Sequence of events

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

- Loss of control - in flight, landing - flare/touchdown
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - flight controls - improper use of, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - go-around - attempted, pilot in command
- In flight collision with terrain/water, descent - uncontrolled
  - airspeed(vso) - not maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command
  - terrain condition - runway
- Gear collapsed, landing - flare/touchdown
  - landing gear,nose gear - overload

## Analysis

THE STUDENT PILOT WAS CONDUCTING TOUCH AND GO TAKEOFFS AND LANDINGS. THE PILOT REPORTED THAT HE ENCOUNTERED A CROSSWIND IN WHICH HE  'COUNTERED WITH A SLIGHT BANK ANGLE.' HE ALSO STATED THAT THE AIRCRAFT BEGAN TO YAW COUNTERCLOCKWISE AND HE TRIED TO CORRECT WITH RUDDER, APPLIED FULL POWER TO TAKE OFF, AND PULLED BACK ON THE YOKE. THE AIRPLANE CONTACTED THE GROUND NOSE FIRST, AT WHICH POINT THE NOSE GEAR COLLAPSED. THE AIRPLANE CAME TO REST APPROXIMATELY 50 FEET SOUTH OF THE RUNWAY. THE SURFACE WINDS WERE 070 DEGREES AT 5 KNOTS.

## FAA reports on this event (1)

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