| Executive Summary: | The aircraft departed the Sundsvall/Härnösand airport on a domestic charter flight with 27 passengers onboard bound for the city of Jönköping. About 17 minutes into the flight during the climb the pilots became aware of a burning smell onboard. The odour became progressively stronger and light haze was observed in the cockpit. The commander contacted the Sundsvall ATC and declared an emergency, asking for radar vectors back to the Sundsvall airport. The return to the Sundsvall was carried out with a depressurised cabin. The haze dissipated rapidly leaving a sticky burning smell. The landing was uneventful. The commander felt that the situation was under control and taxied the aircraft to the terminal building where the passengers disembarked. An investigation of the problem revealed that one of the bolts on the connection terminal board in front of the instrument panel for the heating element in the right front windshield was loose. The electrical cable and terminal board in this area had been exposed to burn damage. The pilots did not don their oxygen masks as detailed in the emergency checklist. The incident was caused by an intermittent connection and arcing around a loose bolt on the connection terminal board, resulting in local overheating and burning smell. |
