I am not Hesham, and I think that our best specialist for the Pa.47 is Jemiba
A good part of the answer is definitely in Les ailes from 02/06/1951. The book is in the files of Le Musée de l'Air at Le Bourget Airport. I copied only 90% of the end of the article (the Pa.47 is not my favorite Payen...).
Well,
+In what I have of Les ailes (06.1951), The
Pa.47,
Pa.47/1,
Pa.47/2 and
Pa.47/3 are named
Week End (1951 then). The only difference between the
Pa.47/2 and
Pa.47/3 is the gear.
+In Le Fana de l'Aviation (1969-70) Robert J. Roux, wrote that the
Pa.47 was at first named
Plein Air and later
Week End. It was still surviving (1969-70 then) and the tricycle gear version
Pa.47-3 was never produced.
+In Les avions français 1944-1964 (1990) Pierre Gaillard wrote :
Pa.47 Plein Air, main flight 18/06/49. Became
Week-End before the modification in
Pa.47-1 with a different rigging (haubanage is the word used in the French text).
+In Le Fana de l'Aviation (1991-92) Francis Nicole wrote about the
Pa.47 Aéria, and after about the flying capacities of the
Pa.47/1 prototype. He wrote after again about two future projects named
Week End : one with classical gear, the other with tricycle gear.
+In Le trait d'Union (1995), Pierre Gaillard wrote :

+In Air Enthusiast (1997), Alain Pelletier wrote : Payen designed a conventional single-engine monoplane powered by a 65 hp Continental A65 in 1947. The so-called
Pa.47 Plein Air (later renamed
Week End) had a high straight wing spanning (...). This aeroplane, which first flew in June 1949 with test registration
F-WFKY, was later converted as the
Pa.47/1, then as the
Pa.47/2 Aéria after its wing had been modified. A tricycle variant was considered
(Pa.47/3) but never materialised.
+In his two books about the official flight tests (by the Centre d'essais en vol CEV) of the french airplanes 1945-60 (2001-2002), Jean-Claude Fayer named the
Pa.47 Plein air F-WFKY. He wrote that the Pa.47 came in the CEV on the 11th October 1949 but because of lot of defects it did not fly and returned to the builder and came again in the CEV (in February according to Pierre Gaillard) to fly on the 7th March 1950.
+In Fast Facts (2007 ?) Ferdinand Käsmann wrote : Payen agreed to build a single Piper Cub look-alike designed before the war by one Remy Gaucher, as
Pa.47 Plein Air. It first flew in 1949 and was later modified several times, becoming the
Pa.471 Week End, the
Pa.472 Aéria and the
Pa.473 Week End, in turn.
+In 2013 in one of his last book (aviation in French Essonne Departement), Pierre Gaillard wrote : The
Pa.47... had a restricted Certificate of Airworthiness (from CEV) in 1950, 5 productions planes were foreseen, but it was certificated only on
24/06/57
+In Le Musée de l'Air files there is two free pages from Roland Payen (I don't remember the year) with :
-
Pa.470 Plein Air, later
Week End, 06.1949,
F-WFKY, design of Gaucher
-
Pa.471 Week End, later
Aéria, 06.1949,
F-PFKY, modified Pa.470
-
Pa.472 Aéria,
1957,
F-PFKY, modified wing
-
Pa.473 Week End,
Pa.47 with tricycle gear
It's the best that i can make for you today...
