As mentioned in the page about Sk 8 Skolfalken, Svenska Aero AB
designed three aircraft in their Falken (Falcon) series - the SA-11
Jaktfalken (”Fighter Falcon”), the SA-12 Skolfalken (”Trainer Falcon”) and
the SA-13 Övningsfalken (”Advanced Trainer Falcon”). First out was a SA-12
Skolfalken, built in 1929. Carl Clemens Bücker, managing director and main
owner of Svenska Aero AB, managed to sell the aircraft to the Air Force.
He also got an order of one SA-13 Övningsfalken, mainly the same design,
but fitted with a stronger engine than the Sk 8. This advanced trainer
(trainer type II) got the designation Ö 8. Like the Sk 8, only one single
Ö 8 was built.
The aircraft was delivered and tested in the summer of 1930. It was based
at Barkarby (later Wing F 8) near Stockholm and got the Air Force number
6301.
The aircraft showed a bad point - it was hard to take out of spin. In
April, 1931, the pilot, Björn Bjuggren, had to bale out when the Ö 8
commenced into spin and the aircraft became completely destroyed after
only 30,5 running hours. Björn Bjuggren became later the promoter of
developing the dive bombing technique in the Swedish Air Force, starting
with the B 4 Hawker Hart. He was a without doubt a daring and skilled
aviator, but perhaps not a very timid personality. Many Air Force officers
became during the years subjected to the bad temper of the later General
Bjuggren.
The Ö 8 was powered by a 7-cylinder air-cooled radial Armstrong Siddeley
Lynx engine of 200 hp. The similar Sk 8 had an AS Mongoose engine of only
135 hp. However, many parts of the two engine types were identical.

Jaktfalken (the latter in the Fighter chapter).
The aircraft got the Air Force Code 6301
and had the manufacturer's C/N 69.

engineer Edmund Sparmann in the cockpit.
