Reims built 337's were TC, (Type Certificate) A23EU, not A6CE. I think I have the numbers correct. Apparently the FAA does not issue AD's for foreign TC's any more.
This also means that STC's approved for 6CE can only be applied to Reims machines by way of Form 337, Field Approval, something I am hitting now.
According to my FAA freinds, Reims owners would be advised to follow the AD's etc for 6CE and apply them to 23EU at least in spirit.
