## Probable cause

THE PILOT'S INADVERTENT STALL/SPIN DURING LOW ALTITUDE MANEUVERS.  RELATED FACTORS ARE GROUND PERSONNEL'S INADEQUATE TRAFFIC ADVISORY, AND THE PILOT'S ABRUPT PULL UP.

## Sequence of events

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

- Loss of control - in flight, maneuvering
  - load jettison - performed, pilot in command
  - traffic advisory - inadequate, ground personnel (contributing factor)
  - pull-up - abrupt, pilot in command (contributing factor)
  - stall/spin - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

THE AIRPLANE WAS OBSERVED OVERFLYING THE AIRPORT FROM SOUTH SOUTHWEST TO NORTH NORTHEAST ABOUT 100 FEET ABOVE GROUND LEVEL (AGL), AT A SLOW AIRSPEED FOR A BANNER DROP.  ANOTHER AIRPLANE WAS SEEN APPROACHING FROM THE SOUTH ABOUT 25 FEET AGL AT A HIGH RATE OF SPEED FOR A BANNER PICK UP. WITNESSES SAW THE FIRST AIRPLANE DROP THE BANNER AND BEGIN TO CLIMB OUT. THEY STATED THE AIRPLANE WAS SLOW, IN A STEEP CLIMB ALTITUDE.  THEY REPORTED THE WINGS ROCKED BACK AND FORTH, THEN THE RIGHT WING AND NOSE DROPPED SUDDENLY.  THE AIRPLANE DESCENDED TO THE GROUND IN WHAT WITNESSES DESCRIBED AS A 'RIGHT HAND SPIN ROTATION' AND CAME TO REST IN A CHURCH PARKING LOT.  SEVERAL WITNESSES REPORTED THE SECOND AIRPLANE PICKED UP THE BANNER AND BEGAN TO CLIMB OUT ALMOST SIMULTANEOUSLY, AND IN CLOSE PROXIMITY TO THE ACCIDENT AIRPLANE.
