## Probable cause

PROPER TOUCH-DOWN POINT NOT ATTAINED AND GO-AROUND DELAYED BY THE PIC. CONTRIBUTING FACTORS WERE A DOWNWIND, CROSSWIND, WEATHER EVALUATION MISJUDGED, WRONG RUNWAY SELECTED AND LACK OF TOTAL EXPERIENCE BY THE PIC.

## Sequence of events

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

- In flight collision with object, go-around (vfr)
  - weather condition - crosswind (contributing factor)
  - weather condition - tailwind (contributing factor)
  - weather evaluation - misjudged, pilot in command (contributing factor)
  - wrong runway - selected, pilot in command (contributing factor)
  - go-around - delayed, pilot in command (cause)
  - proper touchdown point - not attained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PLT SAID THAT ON HIS SECOND ATTEMPT TO LAND, IN A QUARTERING DOWNWIND ENVIRONMENT, HE ELECTED TO ATTEMPT A GO-AROUND WHICH RESULTED IN A COLLISION WITH A TREE, THEN THE TERRAIN.
