Linjeflyg Flight 277 (actually LF267V), a Convair CV-340 Metropolitan (SE-CCK), crashed during the approach to Ängelholm-Helsingborg Airport, Sweden, at the time an air force base. The crew had aborted approaches to two previous scheduled destinations (complete schedule: Bromma - Hultsfred - Halmstad - Ängelholm) due to bad weather and low visibility.
The crew abandoned the set procedure in the approach to Engelholm after the tower reported improved weather. When the flight reached Engelholm the visibility was 1.5 to 2 km, the cloud base at 60 m coupled with rain. As a consequence, the pilots began the descent too soon and on a faulty course. A likely reason for this was that the crew allowed themselves to be misled by an arrangement of lights peculiar to the military airfield with which, apart from certain information received during the approach, they were not acquainted.
Descended prematurely struck the ground 2kms short of runway 14 and caught fire.
PROBABLE CAUSE: "The cause of the accident was in all probability that during the approach in instrument conditions the crew abandoned the set procedure and began the landing too soon. The reason for this must have been that the crew allowed themselves to be misled by an arrangement of lights peculiar to the airfield with which, apart from certain information received during the approach, they were not acquainted."
