## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - roll/run
  - flight/nav instruments,airspeed indicator - foreign object damage (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)

## Analysis

DURING AN ABORTED TAKEOFF, EXECUTED DUE TO AN INOPERATIVE AIRSPEED INDICATOR, THE ACFT SWERVED OFF THE LEFT SIDE OF THE RWY ACROSS A DITCH, DAMAGING THE LEFT WING & MAIN LANDING GEAR. A CLOGGED PILOT TUBE WAS THE CAUSE OF THE AIRSPEED INDICATION OF ZERO MPH. STEERING & BRAKE ACTION WERE DETERMINED TO BE NORMAL.
