## Sequence of events

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

- On ground/water collision with object, takeoff - roll/run
  - planning/decision - not performed, pilot in command (contributing factor)
  - in-flight planning/decision - poor, pilot in command (contributing factor)
  - aborted takeoff - initiated, pilot in command (contributing factor)
- Nose gear collapsed, landing - roll
  - remedial action - delayed, pilot in command (cause)

## Analysis

THE PILOT STATED HE HAD MAD A NORMAL LANDING ON A PAVED CITY STREET IN A HOUSING DVELOPMENT THINKING THAT IT WAS THE QUINCEY MUNICIPAL AIRPORT. AFTER THE PILOT REALIZED HE AHD MADE A MISTAKE A TAKE OFF WAS ATTEMPTED. DURING THE TAKE OFF THE PILOT ABORTED THE ATTEMPT, AND DURING GROUND ROLL WENT THROUGH A FENCE AND DITCH BEFORE COLLAPSING THE NOSE GEAR. THE SEATTLE SECTIONAL CHART DEPICTS THE QUINCEY MUNICIPAL AIRPORT AS 'OTHER THAN PAVED' AND THE AIRPORT/FACILITY DIRECTORY LISTS THE 09-27 RUNWAY AS 'TREATED GRAVEL'.
