Beskrivelse

A German light aircraft was en route from Lofoten to Trondheim with three people on board. The flight was to be conducted in accordance with the visual flight rules (VFR) but, in Nord-Trøndelag county, the aircraft entered an area of reduced visibility. The aircraft was observed flying low over hilly terrain where the highest peaks were shrouded in fog. One witness heard the engine noise increase and saw the aircraft climb until it crashed about half way up the steep terrain at the southern end of Søvatnet lake in Bjugn municipality. The occupants were fatally injured in the accident. The aircraft was destroyed.

The AIBN has concluded that this was a weather-related accident. The flight continued into an area with marginal weather conditions instead of turning in due time. The investigation has shown that the air traffic services informed the commander that there was poor visibility along the coast, and better conditions further inland. No request for assistance or distress call was registered from the aircraft at any time.

The AIBN issues one safety recommendation in this report.

Sikkerhetstilråding

Sikkerhetstilråding SL nr. 2013/05T

På et tidspunkt mellom to METAR’er gikk sikten ned fra over 10 km til 2 000 m, uten at dette gjenspeilte seg i publiserte observasjoner. Med halvtimes intervall på utstedelse avMETAR, er det ikke krav om utstedelse av SPECI selv ved signifikant siktreduksjon. Forsinkelser i informasjonsformidlingen er uheldig i et land som Norge, der topografiske forhold gjør at været skifter raskt.

Statens havarikommisjon for transport tilrår Luftfartstilsynet å vurdere om bestemmelser om flyværtjeneste bør endres slik at det blir krav om raskere kunngjøring av signifikante værendringer.
