## Probable cause

POOR IN FLIGHT PLANNING DECISION BY THE PILOT IN COMMAND. CONTRIBUTING TO THE ACCIDENT WAS THE PARTIAL BLOCKAGE OF THE PITOT STATIC SYSTEM AND INCORRECT AIRSPEED INDICATOR.

## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - pitot/static system - blocked(partial) (contributing factor)
  - flight/nav instruments,airspeed indicator - incorrect (contributing factor)
- Overrun, landing - roll
  - in-flight planning/decision - poor, pilot in command (cause)

## Analysis

AFTER TAKEOFF PLT OBSERVED THAT THE AIRSPEED INDICATOR WAS INDICATING LOW, AND THAT THE ACFT WAS BANKING TO THE RT UNCOMMANDED.  HE LANDED FAST AT AN ARPT 12 NM AWAY, TRAVELLED OFF THE END OF THE RWY, AND COLLIDED WITH BUSHES.  FUEL IMBALANCE WAS NOT A FACTOR.  A MECHANIC WHO REPAIRED THE ACFT REPORTED THAT THE PITOT STATIC SYSTEM WAS PARTIALLY BLOCKED BY CONTAMINANTS.  THE RIGGING OF THE AILERONS AND FLAPS CHECKED SATISFACTORY.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
