Sikorsky S-76B Spirit, G-DPJR
During cruise, whilst operating on a night positioning flight, the aircraft’s auxiliary heater system overheated, melting the surrounding ducting and progressively filling the cockpit with smoke. The crew declared an emergency and expedited their landing, the smoke and heat subsided once the aircraft had been shut down on the ground. The electronic control box for the heater was removed and subsequently confirmed to have failed, probably disabling the overheat protection and cockpit controls for the system. One Safety Recommendation is made.
