Penair Flight 4266 Near Midair Collision During Localizer Approach (N620PA)

Dillingham, AK, US

On June 26, 1992, a Fairchild SA227-AC (registration N620PA) operated by Peninsula Airways, Inc. was involved in an aviation accident near Dillingham, AK. Investigators recorded the probable cause as: THE VISUAL LOOKOUT THAT WAS NOT MAINTAINED BY THE PILOT OF THE OTHER AIRPLANE. FACTORS WERE THE DRIZZLE AND FOG AND THE IMPOSSIBILITY OF UPDATING THE RECORDED WEATHER INFORMATION BY ATC PERSONNEL.

Penair Flight 4266, on a localizer DME approach to Runway 19, broke out of clouds at 800 feet MSL and saw another aircraft directly ahead. After evasive action, the aircraft passed within 100 feet of each other. Weather observations were conflicting at the time.

Incident Overview

Penair Flight 4266 was cleared for a localizer DME approach to Runway 19. While executing the approach, the aircraft broke out of clouds at 800 feet MSL and 4.8 DME from the airport. The crew immediately observed another aircraft directly in front of them. After taking evasive action, the two aircraft passed within 100 feet of each other.

Weather Observations

A special weather observation, taken one minute prior to the near midair collision but not yet transmitted, indicated that the control zone was below visual meteorological conditions (VMC). However, the previous hourly observation and the most current transmitted observation both showed that the control zone was under VMC. This discrepancy meant that the controller and crew may have been relying on outdated or conflicting weather information at the time of the incident.

Evasive Action

The crew of Penair Flight 4266 reacted immediately upon seeing the other aircraft. The evasive maneuver prevented a collision, with the two aircraft passing within 100 feet of each other. No further details about the maneuver or the other aircraft were provided in the source.
