## Sequence of events

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

- Loss of engine power(total) - nonmechanical, maneuvering
  - fluid,fuel - starvation (cause)
  - maneuver - performed, pilot in command (cause)
  - aircraft performance,yawing maneuvers - erratic (cause)
- Forced landing, landing - flare/touchdown
- Main gear collapsed, landing - flare/touchdown
  - landing gear,main gear - overload (contributing factor)

## Analysis

THE ACFT COLLIDED WITH THE GROUND AFTER AN ENG FAILURE WHILE STRINGING POWER LINES. THE ACFT WAS IN A RIGHT SIDE LOW, NOSE HIGH ATTITUDE PULLING A WIRE ATTACHED TO THE LEFT SIDE OF THE ACFT. THE WIND WAS FROM THE RIGHT REAR QUARTER WHEN THE LOSS OF POWER OCCURRED WITHOUT WARNING. THE ACFT ROTATED 45 DEGREES & THE PLT ONLY HAD TIME TO LEVEL THE ACFT AND MAKE A PITCH PULL PRIOR TO IMPACT FROM THE LOW ALTITUDE OF 150 FT AGL. THE ACFT IMPACTED LEVEL WITH NO FORWARD SPEED, THE SKIDS FAILED AND THE ACFT ROLLED OVER. THE PLT SUSPECTED FUEL STARVATION DUE TO ACFT ATTITUDE AND INERTIA. THE ACFT HAS ONE FUEL PICK-UP IN THE TANK.
