NTSB Recommends FAA Review of Aircraft Overhead Panel Circuit Design
The National Transportation Safety Board urges the Federal Aviation Administration to assess the feasibility of replacing specific emergency power switches and removing nonessential high current components from cockpit areas.
The National Transportation Safety Board has issued a recommendation directed at the Federal Aviation Administration regarding aircraft electrical system safety. The board advises the agency to determine the feasibility of replacing the emergency power switch, identified as part number 103-2200, with a relay type circuit. Additionally, the NTSB suggests developing a design that would remove all nonessential high current relays and wires from aircraft overhead panels and the cockpit area. This recommendation aims to address potential safety concerns associated with these specific components in aviation operations.
