Comparing Fw190 with French-built NC-900

My impression of the Fw190 or NC-900 in Armee de l’Air post-war use, is of a short-career which was plagued with large numbers of engine failures, and other general maintenance problems.

Would anyone like to venture some knowledge or an opinion as to why that might be?

My question is along the following lines of:
- was the NC-900 engine failures/maintenance issues much different to the Fw-190 in Luftwaffe use in late 1944 or early 1945?
- did French construction practices have a significant effect (i.e. deliberate poorer quality control in 1944-45, in the knowledge that the aircraft were destined for German-use) – although, not quite outright sabotage, but perhaps much lower care-factor?
- did the 2-3(?) year service life simply reflect the availability of more suitable aircraft?
- a combination of the above?

The subject was discussed briefly here a few years ago:
http://forum.12oclockhigh.net/showth...ghlight=NC-900

Admittedly, my reference material on the NC-900 in post-war use is limited. So hopefully, someone can shed some more light on the matter.

You have to take in account the incredible number of american bombers and fighters that came in French use 1944 onwards. Dirt cheap and easy spare parts.


No need for NC900 not militair nor economical

Re: Comparing Fw190 with French-built NC-900

There are a number of comments available that production standards of German aircraft had fallen dramatically in the later stages of the war. I don't think that you need to look much further than that. As for the ready availability of US types, that didn't prevent considerable use of other German types such as the Ju88, Do24, Ju52, Seibel 204s, Me108s and Arado trainers. This suggests that the short service life was not because the French could obtain cheap US types. However, it does suggest a difference between the types mentioned and the F1w190 - I suggest low quality of the complex BMW 801 engine which was not otherwise available from French sources.

Edit: improvement to the English. What I meant not what I typed!

Read this. It will underline what Graham Boak wrote.

The French Fw190
It was in France that a number of Fw190 began a new career. At the end of 1944, the liberation of the French metropolitan territory was being completed, it was discovered dozens of cell and body and a hundred engines abandoned by the Luftwaffe in several French plants. It was basically A-5, A-7 and A-8 incomplete or being repaired found in Cravant in Yonne.
The management of the factory Cravant was entrusted to the National Society of Aerospace Engineering Centre (SNCAC), which had a contract from the Air Ministry to complete a batch of cell and fuselage. Refurbishment and overhaul of engines was entrusted to the company Voisin, she was also very difficult to rehabilitate them, most of these engines had been deftly sabotaged by the French workers forced to make them. Engines for these hunters were found in deposits all over France, particularly in St Astier where a hundred under review engines were found in an underground factory installed in caves. These caves are still used today as a deposit by the Army.
This option, choosing the government of the time, allowed to have a transitional aircraft pending the development of a purely French plane equivalent or higher. For France, bled after four years of occupation, the savings was substantial because a Fw190 and reconditioned cost 1.5 million francs at the time against 12 million for a "Spitfire" bought new in Britain .dropoff window
Designated NC900 (sometimes AAC5 or AAC6 few photos) the first of these Fw190 recovered complete the flight test was an A-5 (NC900 No. 1) 16 March 1946. The tests lasted until mid-April with 4 other devices while SNCAC ended requested hunters. In May, the aircraft was certified. The AAC5 or 6 more visible designation period photograph and recovery in some works, probably comes from the fact that the two factories who controlled and gathered the NC900 were the Aeronautical Workshops Cravant (AAC6) and the Aeronautical Workshops Courbevoie (AAC5) any two property SNCAC.
The hunting group that was assigned the "NC900" was the group "Normandie-Niemen" (I bet the drivers just returned from Russia have little appreciated the situation, especially as they returned with their Yack with whom they fought, offered by Russia for services rendered!). As trials continued, the NC900 first arrived at the Le Bourget airport and were taken into account by the III / 5 Normandie-Niemen. But even repaired and overhauled the engines were unreliable, other problems arose, the French engineers used to more rustic devices, only happened difficult to solve the notorious and delicate "KommandoGeräte." Other problems caused some accidents, giving a bad name to the device. The poor availability and lack replacement quickly decided the authorities to ban flying handle NC900 still in flying condition in mid 1947, most were scrapped. The decision to remove them also been made aware 1946. Some devices served a few more years (NC900 No. 54 and 60 at least) to the CEV Cazaux and Bretigny until 1949, another was transferred to the Naval Aviation (the first flotilla Cuers it seems) and broken after a few flights, others have probably used here and there but I have no verifiable information, a final (NC900 No. 62) was preserved as is, then restored in the colors of JG26, it is visible at the Le Bourget Air Museum.

camo information collected on former Aviation (Goose Pendelton)
Color is hard to know on NC 900, as on all planes "French" of that time. Originally, the desire was to paint aircraft in olive drab, US to do more, even add even landing strips long after D day. In practice painters made for the better. There were mostly German painting of stocks, it was used. Then we mixed it all to make a nice "goose poop", very close to the olive drab. MS 500, 1000 NC 900 North had this color, top and bottom. The mixture does not take into account the fact that these paintings do not have the same chemical origin, it ensued a strong tendency to premature degradation, especially as for reasons of economy, there was no put under layer zynchro. If you see the pictures, you will see the degradation of the paint after a few months of use !!!
