Narrative:

This was a fatigue call issue due to an impossible reschedule. Original trip was two legs with 7 hours of duty. Reschedule was four legs with 14 hours of duty ending late at night. Then I was told to call when I get to destination to start exactly 8 hours of rest to one leg early followed by 10 hours of rest in the middle of the day and then one leg in the evening! If this sounds too incredible to believe I assure you its true. After the second leg; I called scheduling and told them this pairing was likely to induce fatigue and I didn't see any way my body could handle it. I was trying to give them advance notice so they could make other plans. They said to call from destination. I called and said I was very fatigued. They offered 9 hours of rest (which would still be reduced) and I said no; I need normal (10 hours) rest to safely operate in the morning. I understand the pairing was legal; but the idea that a person can work a 14+ hour day and then sleep a minimal 6 or so hours before returning to work is beyond my comprehension.many many things could and should be change. This pairing reschedule delves into the heart of the reasons this industry needs comprehensive restructure of pilot duty/rest rules. It shows that the idea of 'rest before you fly' doesn't always work well. If your morning schedule is short enough; you can legally be put on absolute minimum rest after an absolute maximum duty day. Even if the morning is just one flight; the reduction of safety for that one flight exists. Also; this pairing has a rest period during the middle of day in a trip where every other day has flying in the middle of the day and rest at night. This creates a rest period where its impossible to sleep.
