## Probable cause

FAILURE OF THE PILOT TO MAINTAIN THE REFERENCE SPEED ON APPROACH AND ESTABLISH A PROPER GLIDEPATH.

## Sequence of events

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

- In flight collision with terrain/water, approach - vfr pattern - final approach
  - terrain condition - berm
  - airspeed(vref) - not maintained, pilot in command (cause)
  - proper glidepath - not attained, pilot in command (cause)

## Analysis

THE PILOT REPORTED THAT HE DEPARTED AT  0620 WITHOUT EATING. A FUEL STOP WAS MADE AT 0900 WHEN HE ATE A SWEET ROLL. THREE HOURS LATER HE ATTEMPTED THE THIRD STRAIGHT IN APPROACH OF HIS FLYING CAREER TO A SHORT TURF STRIP. HE STATED HE FIXATED ON THE IDEA THAT HE MUST SLOW THE AIRPLANE FOR THE SHORT FIELD, BUT DID NOT CROSS CHECK THE AIRSPEED INDICATOR. RATHER, HE CONCENTRATED SOLELY ON THE ALTIMETER AND THE RUNWAY. CONSEQUENTLY, UPON APPLICATION OF FULL POWER FOR A GO-AROUND, THE LEFT WING DROPPED. THE AIRPLANE HAD SLOWED BELOW THE SPEED FOR AILERON EFFECTIVENESS. THE PILOT ALSO REPORTED THAT HIS REST AND DIET HAD BEEN INADEQUATE FOR THE WEEK PRIOR TO THE ACCIDENT.
