Narrative:

I fly a commuter airline which is operated under scheduled part 135 flight time limitations. I was scheduled to fly under 34 hours in 7 consecutive days, but I inadvertently flew over the 34 hours in 7 consecutive days. The problem came about after I flew 4 consecutive days which added up to 28.7 hours. I then had 2 days off and was scheduled to fly again on the seventh day. At the time I didn't realize that this was the seventh consecutive day. I flew 8.1 hours on this day which gave me a total of 36.8 hours in 7 days. I thought because of my time off, and my scheduled flight time was under 34 hours in 7 days, I would be fine to continue the trip. But unfortunately after I added up the actual flight time it exceeded the limit. I feel that the responsibility should be somewhat covered by crew scheduling instead of myself alone because there is always human error when it comes to things like this. The company says that their computers catch such errors before they happen; as it was, they didn't see it this time. I feel that the pilot should be aware that nobody but himself will be able to catch these errors in the future.

Title: COMMUTER PLT EXCEEDS 34 HOURS IN 7 DAYS RULE.

Narrative: I FLY A COMMUTER AIRLINE WHICH IS OPERATED UNDER SCHEDULED PART 135 FLT TIME LIMITATIONS. I WAS SCHEDULED TO FLY UNDER 34 HRS IN 7 CONSECUTIVE DAYS, BUT I INADVERTENTLY FLEW OVER THE 34 HRS IN 7 CONSECUTIVE DAYS. THE PROB CAME ABOUT AFTER I FLEW 4 CONSECUTIVE DAYS WHICH ADDED UP TO 28.7 HRS. I THEN HAD 2 DAYS OFF AND WAS SCHEDULED TO FLY AGAIN ON THE SEVENTH DAY. AT THE TIME I DIDN'T REALIZE THAT THIS WAS THE SEVENTH CONSECUTIVE DAY. I FLEW 8.1 HRS ON THIS DAY WHICH GAVE ME A TOTAL OF 36.8 HRS IN 7 DAYS. I THOUGHT BECAUSE OF MY TIME OFF, AND MY SCHEDULED FLT TIME WAS UNDER 34 HRS IN 7 DAYS, I WOULD BE FINE TO CONTINUE THE TRIP. BUT UNFORTUNATELY AFTER I ADDED UP THE ACTUAL FLT TIME IT EXCEEDED THE LIMIT. I FEEL THAT THE RESPONSIBILITY SHOULD BE SOMEWHAT COVERED BY CREW SCHEDULING INSTEAD OF MYSELF ALONE BECAUSE THERE IS ALWAYS HUMAN ERROR WHEN IT COMES TO THINGS LIKE THIS. THE COMPANY SAYS THAT THEIR COMPUTERS CATCH SUCH ERRORS BEFORE THEY HAPPEN; AS IT WAS, THEY DIDN'T SEE IT THIS TIME. I FEEL THAT THE PLT SHOULD BE AWARE THAT NOBODY BUT HIMSELF WILL BE ABLE TO CATCH THESE ERRORS IN THE FUTURE.
