A Wideroe de Havilland Dash 8-100, registration LN-WIP performing flight WF-834 from Bodo to Svolvaer (Norway), had been holding at FL090 about 13nm southsouthwest of Svolvaer before commencing the straight in approach to Svolvaer's runway 01 in instrument meteorological and night time conditions. While descending through about 1000 feet indicated altitude the crew received a GPWS warning and initiated a go around. The crew subsequently decided to return to Bodo where the aircraft landed safely.

At the time the barometric pressure QNH was 987 hPa causing the transponder altimeter, which always indicates according to QNH 1013.25 hPa, to indicate 1000 feet, when the aircraft however was 774 feet lower and just about 226 feet AGL over the water surface about 3nm before the runway threshold.

Norway's Havarikommisjonen (AIBN) rated the occurrence a serious incident and opened an investigation stating the crew received a "Pull Up!" GPWS warning, went around and returned to Bodo. They were flying about 700 feet lower than their indicated altitude and 700 feet lower than they thought due to an uncorrected altimeter.

Norwegian Media reference a different flight performed on Oct 12th 2022 by LN-WIA in their links.
