In service with NEIAF.
Just after the First World War the Dutch East Indies bought several airplanes to set up the new Flight Division of the NEI Army. Besides a number of Airco DH-9s, a number AVRO 504Ks was bought.
The first two Avro 504 arrived in August 1919. In 1922, another twelve aircraft were delivered.
The AVRO 504K was used as training aircraft. Despite a number of accidents, the aircraft did very well.
In 1924 a start was made to built an improved version of the AVRO 504K, initially at Andir, later at Soekamiskin. These AL aircraft had a plywood fuselage and improved fuel tank. The prototype was the LA-1 (later serialled as AL-57).
Late twenties and early thirties was a replacement was necessary and one Fokker S. IV and one Morane-Saulnier AR-35-EP-2 were bought. The AVRO turned out to be at least as good as these both types. So most remaining units were given a facelift in 1931; an Armstrong Siddeley Mongoose engine was built in to replace the Clerget rotary engine. These were re-serialled "AM" with the original aircraftnumber. In 1938, the last Avro 504K went out of service.
