NTSB Issues Safety Recommendation to Bombardier Regarding DHC-8 Windshield Heat Systems

The National Transportation Safety Board (NTSB) has issued a formal safety recommendation, designated as A-16-003 and referenced under NTSB number ENG15IA024, addressed directly to Bombardier, Inc. This directive focuses on the electrical systems of Bombardier DHC-8 airplanes. Specifically, the NTSB requires the manufacturer to redesign the windshield heat power connection across all models in this series. The primary objective of this redesign is to ensure that the electrical connection is both mechanically secure and maintains low resistance. This action aims to address potential reliability issues within the heating system components. The recommendation serves as an official call for corrective engineering measures to be implemented by the aircraft manufacturer.
