Laurence G. Hanscom Field Airport
Aircraft Accident/Incident Report

Bedford, Massachusetts 01730
Friday, October 2, 1998 14:00 EDT

NTSB Narrative Summary Released at Completion of Accident

After arriving at the airport, the pilot landed and waited for the ground crew to arrive and assemble the mooring mast. Once the mast was assembled, the ground crew took over and the pilot assisted with thrust to move the airship upwind to the mooring mast. The conditions at the time of the accident were challenging, but not uncommon for airship operations. The injured ground handler was moving from one recovery position to another trying to provide assistance where needed most. Once the pull-in-line was set, the injured ground handler went to assist. While using his 200 pound body to help pull the airship to the mooring mast the pull-in-line broke, and the ground handler fell from a standing position, injuring his back. The winds at the airport were reported to be from 280 degrees at 16 knots, gusting to 24.

NTSB Probable Cause Narrative

The separation of the pull-in-line. A factor in the accident was the gusting winds.
