## Probable cause

INADVERTENT STALL. FACTORS WERE: TAILWIND, WRONG RUNWAY SELECTED, AND FAILURE TO RAISE FLAPS.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - raising of flaps - not performed, pilot in command
  - inadequate training, pilot in command (cause)
  - weather condition - tailwind
  - wrong runway - selected, pilot in command (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE STUDENT PILOT HAD BEEN FLYING ON A SOLO CROSS-COUNTRY FLIGHT WHEN HE BECAME LOST AND LANDED AT THE NEAREST AIRPORT TO FIND OUT WHERE HE WAS. WITNESSES STATED THAT THE PILOT DID NOT REFUEL AND WENT OUT TO HIS AIRCRAFT IN A HURRY. THE AIRCRAFT WAS OBSERVED TAKING OFF DOWNWIND WITH FULL FLAPS. SHORTLY AFTER TAKEOFF, THE AIRCRAFT WAS OBSERVED MAKING A STEEP LEFT BANK AND THEN THE NOSE SUDDENLY DROPPED. THE AIRCRAFT IMPACTED THE GROUND IN A STEEP NOSE LOW ATTITUDE AND CAME TO REST UPSIDE DOWN.
