I have heard that scheduling at a particularly crappy regional has been forcing pilots to fly over the 16 hour duty day by making them go over 16 hours for "part 91 ferry flights" and saying that since they are not 121 passenger flights, it is legal and that they have to do it- mostly to FOs on probabation who can be easily fired and intimidated if they try to say they are fatigued. It sounds kind of fishy to me- I don't think it is legal, but I fully admit I don't know for certain. Anybody know for certain and have the reg. number so that they can be quoted to scheduling and flight managers who are doing the intimidating?
