For example, a small airport had a few incidents with aircraft under tow to the hangars. In a
few cases, the wingtip of the aircraft struck the doors or the internal structures of the hangar.
An SRA with the airport director and staff responsible for towing aircraft helped to revise the
existing SOP and reduce the likelihood of the incident occurring. During the brainstorming
session, the group identified each step of the towing process (e.g., place work order, assign tow
crew, select tow equipment, hook up, tow, maneuver aircraft in/out hangar, and park and secure
aircraft). Risks were assessed for each step of the proposed procedure, and the procedure was
reviewed again to address the higher risks.
