F-BOZS History and Reference

DR221 “Dauphin” registered as F-BOZS (Foxtrot Bravo Oscar Zulu Sierra), is the 74th built by Pierre Robin manufacturer as mentioned in the official “control register” below.

It left the Pierre Robin factory assembly line on the “Dijon-Darois” airfield on 8th September 1967 powered with 115hp Lycoming O-235-C2A engine.

The end of the assembly of the aircraft is sanctioned by a test flight performed the same day by a flying ace: Léon Vuillemain (22th March 1915 – 10th October 1974).

That’s F-BOZS birth certificate.

After this test flight, the aircraft has been flown to “Chartres” airfield (LFOR) where it has been operated by the “Eure-et-Loir” flying club for seven years.

Then it has been owned successively by two private pilots and has been based at “Chavenay” (LFPX) then at “Toussus-le-Noble” (LFPN) prior to arriving at Courbevoie’s flying club at “Saint-Cyr l’Ecole” airfield (LFPZ) on 22nd August 1983 as mentioned in its log book.

Since then, it has been used at Courbevoie’s flying club for young pilots training but also for leisure flights (it has been used for trips to Italy and North Africa).

In 2000, F-BOZS appeared in a book from the famous French aeronautical historian “Pierre Gaillard” entitled “Fabuleux avions du monde” among other mythical aircraft.


This book shows many pictures of legendary aircraft such as Charles Lindbergh’s Spirit of St Louis.

Finally, it has also been modeled into “Microsoft Flight Simulator” by a team of enthusiasts in order to virtually fly this beautiful yellow and grey aircraft.
