Notes

  • Built from a 1925 German design
  • An excellent training machine, with a slow landing speed and few 'vices'.
  • Equipped with dual controls for the training function, with the instructor sitting in the front and the student behind.
  • 1927 - two German pilots from the Bayerische Flugzeugwerke demonstrate the U-12 Flamingo in Latvia. [Irbitis] Note: [van Ishoven] states the demonstration flight took place in Summer, 1928.
  • Originally the Latvian military was considering building Avro trainers, but the license fees being demanded were excessive and this idea was dropped. Building a locally designed trainer at A.S.Christine Backman seemed to be the next best solution, until the Udet Flamingo was seen on the demonstration flights, when it immediately became the trainer of choice.
  • Summer, 1929 - A.S.Christine Backman obtains a contract to build 10 U-12bs and a complete set of plans is provided by BFW.
  • While Latvian manufacturers had no difficulty with the wooden parts (Latvian pine and birch plywood were quite suitable) they initially had to buy some of the Duralumin parts from BFW. However, the aircraft completed by the Aviation Regiment Workshops had the parts produced locally.
  • The Hugo Heine propellers, instruments and wheels were ordered directly from their German manufacturers.
  • Autumn, 1929 - A.S.Christine Backman begins construction of the U-12 Flamingos at their new facility in Bisumuiza, a suburb of Riga.
  • Summer, 1930 - the Flamingo aircraft are completed and delivered to the Military Aviation School.
  • July 25, 1930 - the Flamingo aircraft are flown for the first time by the Military. The pilots were the recent graduates of flight school - Jenkevics, Ozolins, Grave, Sapratnieks, Sleiters and Krastins.
  • Markings: "Some of the Latvian Flamingos were clear varnished, carrying a black number on their silver rudder, while others were dark green overall with a white outlined black number on the rudder."
  • 1936 - two of the Flamingos are modified to accept a full blind-flying panel and fitted with a hood over the rear cockpit to make them suitable for instrument flight training.
  • 1936 - in an effort to standardize aircraft types by code, the Flamingos as designated as type A-1.
  • The last of the Flamingos were still flying in the spring of 1940, where they were being utilized as Aeroclub trainers and were training the 5th graduating class at Kalnciems (they had been gifts from the Aviation Division).
  • After the Soviet occupation, all (or most) of the Flamingos were destroyed when the building in which they were stored caught fire and burned to the ground.

    • August 4, 1930 - crashed (pilot: vltn. Lakstigala)

  • # 77
    • this aircraft was experimentally fitted with the Czech Walter Mars 145-hp radial engine, but it was later replaced with the standard SH12.
    • August 12, 1930 - crashed (flight instructor vltn.Trejs with student, Salmins)
  • # 86
    • Sept. 15, 1930 - crashed (pilot: Nikolajs Balodis)
  • # 87
    • June 2, 1931 - crashed (pilot: Greizis)
    • August 31, 1931 - crashed (pilot: Bungss)
  • # 89

  • # 95
    • 1935 - the Aviation Division workshops builds an additional Flamingo, assigned the number 95.
    • July 1, 1935 - #95 is test flown and approved by capt. A.Dzenitis.
    • November 4, 1935 - midair collision with Bristol Bulldog #81. Three fatalities. This was the only fatality associated with the Flamingo, which is a remarkable record considering its role as a primary trainer.
