## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - vfr pattern - base leg/base to final
  - fluid,fuel - exhaustion (cause)
  - in-flight planning/decision - inaccurate, pilot in command (cause)
- In flight collision with terrain/water, landing
  - airport facilities,runway/landing area condition - uphill (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - airport facilities,runway/landing area condition - none suitable (contributing factor)
  - airport facilities,runway/landing area condition - rough/uneven (contributing factor)
- Gear collapsed, landing - roll

## Analysis

A TOTAL LOSS OF POWER OCCURRED DUE TO FUEL EXHAUSTION WHILE IN AN EXTENDED TRAFFIC PATTERN DUE TO LANDING TRAFFIC. AN INADVERTENT STALL OCCURRED PRIOR TO TOUCHDOWN. THE LEFT WING STRUCK A PILE OF DIRT WHICH SPUN THE AIRCRAFT AROUND. THE LANDING WAS ACCOMPLISHED UPHILL.
