So yes, you can call me stupid.....
3.3% is above the minimum required 2.4% climb gradient for the OEI scenario (2 engined aircraft).
I would assume that the final climb gradient (4th segment) of 1.2% should be enough to climb safely above MSA from the position I am following a single engine procedure. If that's the case, the answer on the orignal question would be a no brainer. And I think it is, as it's the responsability? of the airline to provide me with save climb-out procedures in case of single engine (JAR). I can't think of an example right now where this would not be the case as most emergency turns would lead you to area's of low terrain or in the direction of facilities which have a published holding procedure.
Food for the brain......
