The Linjeflyg pilots, misled by a non-conventional military runway light configuration, descended too early and on a faulty course during approach to Ängelholm–Helsingborg Airport.

The flight was en route from Stockholm to Ängelholm, but bad weather caused it to skip stopovers at Hultsfred and Halmstad.

There was less than 2.0 kilometers (1.2 mi) visibility and a low cloud base at Ängelholm, so air traffic control lit its approach lighting system.

It had production date 23 June 1954 and was delivered to Real Transportes Aéreos of Brazil on 17 November 1955, where it was registered as PP-YRC.

This made the aircraft superfluous and it was subsequently sold to Linjeflyg on 13 December 1961 through the holding company Airtaco.

Given the weather conditions this was a highly unusual landing plan: normal procedure would be to turn northwest and carry out an instrument approach instead.

[3] Ängelholm tower contacted the flight crew at 20:57 and issued the latest weather report, which was for a slight clearing.

This was discovered by the pilots prior to impact and they attempted to pull the aircraft up, but hit a field with its starboard wing tip and landing gear.

The fire departments in Ängelholm and Vejbystrand arrived at the scene eleven minutes after the crash and started freeing the survivors.

[6] An ad hoc investigation was appointed and later that night a Douglas DC-3 of officials and experts from the airline and the CAA were dispatched to Ängelholm.

Linjeflyg pilots reported that they had previously made the same mistake, but that the issue had otherwise always been detected and they had corrected their course, landing safely.

SFTF responded by an official letter to the government questioning why the pilots were represented in the commission, as this could pose a potential conflict of interest.

This was caused by the crew misunderstanding the lighting arrangement at the airport due to lack of proper information about its configuration.

It placed responsibility with both the CAA and the Air Force for the inadequate configuration of the lighting system and for not properly following civilian regulations at military airports.

The commission's findings caused an increased focus on safety by the Civil Aviation Administration and a shift in attitude.

Specifically, the military air bases with joint traffic were reconfigured to meet international civil standards in their instrument landing and lighting systems.
