## Probable cause

PROCEDURES/DIRECTIVES WERE NOT FOLLOWED.  FACTORS TO THE ACCIDENT WERE: IMPROPER FUEL BOOST PUMP SELECTOR POSITION, LEADED SPARK PLUGS AND SUNGLARE.

## Analysis

WHILE IN THE PATTERN FOR LANDING, THE ENGINE EXPERIENCED A LOSS OF POWER. THE PILOT WAS UNABLE TO LAND ON THE RUNWAY AND A FORCED LANDING WAS INITIATED TO AN OPEN SCHOOL YARD. DURING THE EMERGENCY DESCENT, THE AIRPLANE COLLIDED WITH POWER LINES AND STRUCK THE GROUND IN A NOSE DOWN ATTITUDE, VERTICAL TO THE TERRAIN.  DURING THE ON SCENE INVESTIGATION, IT WAS FOUND THAT THE SPARK PLUGS WERE COATED WITH A LAYER OF BLACK CARBON. COCKPIT INSPECTION REVEALED THAT THE AUXILIARY FUEL PUMP SWITCH WAS POSITIONED IN THE LOW SETTING.  THERE WERE NO MECHANICAL FAILURES OR MALFUNCTIONS NOTED.

## 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
  - ignition system,spark plug - leaded (contributing factor)
  - fuel boost pump selector position - improper, pilot in command (contributing factor)
  - procedures/directives - not followed, pilot in command (cause)
  - maintenance,inspection - poor, company maintenance personnel
- In flight collision with object, descent - emergency
  - object - wire,static
  - light condition - sunglare (contributing factor)
