Aviation Accident

Quick Launch

NTSB Identification: ANC14CA076
14 CFR Part 91: General Aviation
Accident occurred Saturday, September 06, 2014 in Gustavus, AK
Probable Cause Approval Date: 12/05/2014
Aircraft: CESSNA U206B, registration: N3862G
Injuries: 5 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was landing at a private airport that is used to support fish cannery operations. A road runs parallel to the runway with multiple intersections where motor vehicles cross the runway. The airport is equipped with a pre-landing alert system to warn ground personnel that an aircraft is approaching. The pilot keys the aircraft radios push to talk switch multiple times, which activates a series of flashing lights and horns.

The pilot reported that before landing he activated the pre-landing alert system, and proceeded to land to the North. After touchdown, but during the landing rollout, at approximately 30 miles per hour, a truck entered the runway and struck the left side of the airplane. The airplane sustained substantial damage to the left horizontal stabilizer and elevator. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.

In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been avoided if the cannery provided initial and recurrent training for all employees on runway safety and aircraft operations. In addition, the pilot recommended better signage be incorporated at all runway intersection crossings, and brush and trees be cleared from the vicinity of the runway thereby increasing visibility.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The motor vehicles operators' lack of attention, and improper decision to cross the runway with the runway alert system active, resulting in a collision with the airplane.
