Yes, as long as it is 10 consecutive hours of rest, uninterupted, no company required duties (communication?), etc. We offer to get day rooms if the client wants a long day. They usually baulk at it since I quess in their eyes we are trying to squeeze more money from them. Alot of times this where the 134 1/2 s really chap my b utt. We had one day where we were already flying the company owner on a couple of 91 legs. A charter request came in shortly before we were arriving back at base. We said we could do it if; 1 we got back x time, or 2 we overnighted. This wasn't good for them since they wanted to return in between those times. They proceed to call up a corporate operator (whose owner happens also to be friends with ours - everyone knows everyone around here). It just so happens that their plane had been on basically the same schedule as ours only in a faster plane. By the time we were pulling in back home this 91 operator was leaving with our potential client. They returned much later that night, probably being "on duty" for 16-17 hours. I asked later if they had a "lease" with them. Of course they said, they were able to write up a "quick lease all legal like". Right. I was ready to do something but our owner didn't want to make waves. What is the best procedure to turn in a known illegal operation? What evidence should you present to whomever you report to?
