Long range flight with rear engine only

[Guy Paris]

If the 337 is issued it's certification as a twin and all flight tests are done with both running, except for the obvious, could it be legal in the eyes of the FAA?
The Boeing 727 could be (2) engined ferried but not without several things to do. Think they were training department pilots only, secure the inop engine, (no rotation), insure as best as posibile the other (2) would continue to run. Others I am sure that I have forgotten. guy, the old 72 driver...
