Aurora, OR, US

On December 12, 1987, a Piper PA-23-160 (registration N3275P) was involved in an aviation accident near Aurora, OR.

A single-engine aircraft collided with a twin-engine aircraft on the taxiway after the latter entered from the right. The pilot of the striking aircraft had a fogged windscreen, impairing visibility during the maneuver.

What happened

The incident occurred while a single-engine aircraft was taxiing from the south end of the ramp area toward the active runway. As the aircraft progressed along the taxiway, a twin-engine aircraft entered the same taxiway from the right side, positioning itself directly in front of the single-engine plane.

The pilot of the single-engine aircraft failed to see the twin-engine aircraft in time to avoid contact. Upon impact, the single-engine aircraft struck the rear or side of the twin-engine aircraft that had just taxied into its path. The primary factor contributing to the collision was the condition of the single-engine aircraft's windscreen, which was fogged at the time of the incident. This obstruction significantly impaired the pilot's forward visibility, preventing the detection of the other aircraft until it was too late to take evasive action.

The investigation

Examination of the event focused on the taxiway geometry and the visual conditions present during the maneuver. Investigators noted that the twin-engine aircraft had successfully entered the taxiway from a right-hand intersection or ramp exit. The critical finding related to the single-engine aircraft was the state of its cockpit glazing. The windscreen was fogged, creating a barrier to clear vision for the pilot.

Findings

The collision resulted from a failure in situational awareness by the pilot of the single-engine aircraft. Contributing factors included:

  • Aircraft registration details were recorded for both involved planes, though specific tail numbers are not provided in this summary text.
  • The fogged windscreen on the single-engine aircraft severely limited the pilot's ability to see the taxiway ahead.
  • The twin-engine aircraft entered the taxiway from the right, crossing the path of the single-engine plane without adequate clearance or visibility for the other pilot.

The lack of clear vision due to the fogged windscreen was the decisive element that prevented the pilot from avoiding the collision with the twin-engine aircraft. No further mechanical failures or weather conditions were cited as primary causes in this specific narrative.

Probable cause

The pilot's failure to maintain adequate visual lookout while taxiing, exacerbated by a fogged windscreen on the single-engine aircraft.
