Det Norske Luftfartselskap — Flight LN-IAW

The Bukken Bruse disaster occurred when a Short Sandringham flying boat crashed during a landing attempt in rough sea conditions at Hommelvik. The aircraft was struck by a wind gust during touchdown, causing the pilots to lose control. The right wing float broke off upon impact, leading the aircraft to roll over and its nose to plough into the water. The fuselage rapidly flooded, and 19 of the 45 people on board were killed.

Report

Investigation Summary

On October 2, 1948, the flying boat Bukken Bruse was operating a domestic Norwegian flight from Oslo to Trondheim. Upon arrival at Hommelvika, the crew encountered poor weather characterized by high winds and white-capped waves. The investigation determined that the pilot-in-command attempted to land in an unfavourable direction relative to the crosswind and within a restricted, short landing area. As the aircraft approached the water for touchdown, a sudden wind gust destabilized the plane. The right wing float struck the water with sufficient force to break away, removing the lateral stability required for a safe water landing. The aircraft subsequently capsized, and the forward section of the fuselage submerged. The rapid ingress of water trapped many passengers in the forward and middle sections of the cabin. Notably, all 26 survivors were seated in the smoking compartment at the rear of the aircraft, which remained accessible to an emergency exit as the nose sank.

Final Conclusions

The official investigation concluded that the crash was caused by the pilot's loss of control while attempting to land the flying boat in challenging conditions. Contributing factors included significant crosswinds, rough seas, and the limited maneuvering space available within the bay at Hommelvik.

Systems & Failure Modes

i

Wing Floats

Stabilizing structures mounted under the outer wings of a flying boat to prevent the wingtips from touching the water during takeoff and landing.

i

Fuselage

The main body of the aircraft, which in a flying boat acts as a hull to provide buoyancy on the water.

The Bukken Bruse disaster, along with other flying boat accidents like the Kvitbjorn disaster, contributed to the Norwegian authorities' decision to phase out flying boat operations in favor of land-based airports and conventional aircraft to improve safety and reliability in challenging weather.
