## Probable cause

THE STUDENT PILOT'S IMPROPER COMPENSATION FOR WIND CONDITIONS,  AND IMPROPER RECOVERY FROM A BOUNCED LANDING.  FACTORS RELATED TO THE ACCIDENT WERE: THE ADVERSE WIND CONDITION AND THE STUDENT'S LACK OF TOTAL FLYING EXPERIENCE.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - improper, pilot in command (cause)
  - recovery from bounced landing - improper, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)

## Analysis

AT THE END OF A X-COUNTRY FLT, THE ACFT WAS ON A SHORT FINAL APCH TO LAND, WHEN THE STUDENT PILOT NOTED A X-WIND. HE TRIED TO CORRECT THE SITUATION; HOWEVER, ABOUT 10 FT ABOVE THE RWY, THE ACFT'S SINK RATE INCREASED.  SUBSEQUENTLY, IT TOUCHED DOWN NOSE WHEEL FIRST & PORPOISED SEVERAL TIMES BEFORE THE PLT REGAINED CONTROL.
