## Probable cause

the pilot's failure to maintain adequate obstruction clearance while taxiing.  A factor in the accident was the pilot's attention being diverted by the movement of two trucks.

## Sequence of events

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

- On ground/water collision with object, taxi - from landing
  - object - vehicle
  - clearance - not maintained, pilot in command (cause)
  - diverted attention, pilot in command (contributing factor)

## Analysis

The pilot was taxiing the aircraft back to its parking space on the taxiway and had to pass some men and heavy equipment which were engaged in widening the taxiway.  The pilot reported that as she began to pass the construction zone she was watching two trucks moving on her right side and misjudged the left wing clearance from a steam roller. The left wing tip collided with the steam roller, damaging the outboard 12 inches of the left wing.

## Factual narrative

On June 12, 1993, at 0958 mountain standard time, a Alon A2,      N6515Q, collided with a steam roller during a post landing taxi   operation at the Goodyear, Arizona, airport.  The aircraft was    owned and operated by the pilot.  Visual meteorological           conditions prevailed at time and no flight plan was filed for the operation.  The aircraft incurred substantial damage.  The steam  roller was not damaged.  The certificated private pilot and the   heavy equipment operator were not injured.  The flight originated at the Goodyear airport on the day of the mishap at about 0900    hours as a local pattern practice flight.

In her written statement, the pilot said that she was taxiing the aircraft back to its parking space on the taxiway and had to pass some men and heavy equipment which were engaged in widening the   taxiway.  The pilot reported that as she began to pass the        construction zone she was watching two trucks moving on her right side and misjudged the left wing clearance from a steam roller.   The left wing tip collided with the steam roller, damaging the    outboard 12 inches of the left wing.
