Société Provençale de Constructions Aéronautiques Designations - 1925-1934

The Société Provençale de Constructions Aéronautiques seems to have used two, concurrent designation systems. The first was a simple Modèle number (using roman numerals). The second used arabic numerals. Neither system seems to have been strictly chronological (or, if they were, it was based on time of design rather than airframe completion).

In fairly typical French fashion, major SPCA design model numbers advanced in tens. Minor model variations changed only the second digit. SPCA routinely applied a 'T' suffix to transport designs. Note that SPCA 30 M4 is an AdlA designation ('M' for Multiplace, '4' for Quatriplace) not an SPCA-applied suffix.

Designation anomolies are: the Paulhan-Pillard T3 floatplane, the Météore 63, and the seemingly unnumbered Hermès (unless, like its cancelled military derivative, Hermès was also designated Modèle V/SPCA 50). Another mystery is the SPCA Type E-5 trimotor flying boat.

http://www.avia-it.com/act/cera_una_volta/pubblicazioni_di_ieri/CUV_pi_agg_luglio_09/14_L_A%C3%A9ronautique_fran%C3%A7aise_1929.pdf see Pg 106 for Type E-5

In layout, the Type E-5 appears identical to the SPCA 10 -- parasol monoplane trimotor flying boat with Warren truss bracing on Consolidated-style stabilizing floats. So why were two different arabic numeral designations applied?

[Update: The E-5 is connected with the Météore 63 in a Popular Aviation article posted by Stargazer2006!

Thanks Hesham. I've added the SPCA 91T. Was this a slight variation on the SPCA 90T airliner? Or a designation?

Thanks for that Hesham. I think that '90T' must have have been my transcription error.

Thanks Hesham. I've added the SPCA VIII/SPCA 80 and SPCA IX/SPCA 90.

A machine translation of your clipping goes something like this:

"SPCA colonial aircraft, VIII and IX, demonstrated a remarkable resilliance. We recall that the IX was able to land despite breaking an engine mount with resulting structural damage from the propeller.

The SPCA VIII and IX are currently in service in Morocco. Also recall that two SPCA VII link Broken Hill with Tananarive; the Company might be called upon to built two or three new
aircraft of this type."

The Broken Hill-Tananarive refers to the SPCA 41Ts of Régie Malagache aka Service de la Navigation Aérienne de Madagascar (SNAM).

In July 1934, Régie Malagache began air mail flights from Broken Hill in Northern Rhodesia to Tananarive in Madagascar via Portuguese East Africa (Mozambique).

Hi all,

I discovered that,Mr. Louis Paulhan and Mr. Marcel Pillard had anther series,and I will
try to track it;

MR-1 was a racer seaplane with float Project,powered by Farman engine
H-2 was a four engined transatlantic flying boat Project of 1928,called Neptune
T-3 was a twin-engined, twin-float low-wing monoplane torpedo bomber seaplane,well known Type-20
H-4 was a four engined transatlantic monoplane seaplane Project of 1931
E-5 was a three engined parasol monoplane,recce and bomber seaplane,well known Type-10
E-6 was a three engined cantilever high wing monoplane Project of 1932,recce floatplane
E-7 was a twin engined transport seaplane,a military derivative of Hermes,or Type-60
H-8 was a three engined transatlantic flying boat Project of 1934

My guess - what if Meteore 63 has been named for "6" passenger and "3" engines?
Just for advertisment purposes?

No my dear Silencer,

but they took CAMS-31 & CAMS-32 for examples and collected the numbers o be this.

Many thanks to my dear Toura.
