Narrative:
I recently transitioned from a 19 seat aircraft to a 50 seat aircraft. The flight time limits between the 2 aircraft types differs (far 121.470 limited to 34 hours in any 7 consecutive days versus far 121.471 limited to any 30 hours in any 7 consecutive days). I inadvertently overlooked this. On oct/thu/99, I flew 1.7 hours. The airline scheduled me (and I accepted) for a trip starting on oct/fri/99, that was 3.3 hours flight time. I was then scheduled for (and I accepted) a trip starting on oct/sun/99, and ending on oct/thu/99, with 26.7 hours flight time. This put my 7 day total at 30 hours (3.3 + 26.7 = 30 hours) prior to starting trip. Some legs on the 5 day trip took longer than scheduled due to ATC delays en route, as a result of which my 7 day limit was exceeded by 1.2 hours (3.3 + 27.9 = 31.2 hours). The airline failed to notify me of this potential exceedance and I inadvertently did not catch it until after the trip when totaling my logbook.

Title: CAPT OF A CANADAIR CL65 REGIONAL JET BELIEVES THAT THE COMPANY FLT SCHEDULING, AND HIS ACCEPTANCE OF SAME, CAUSED HIM TO EXCEED FLT DUTY TIME IN A 7 CONSECUTIVE DAY PERIOD.
Narrative: I RECENTLY TRANSITIONED FROM A 19 SEAT ACFT TO A 50 SEAT ACFT. THE FLT TIME LIMITS BTWN THE 2 ACFT TYPES DIFFERS (FAR 121.470 LIMITED TO 34 HRS IN ANY 7 CONSECUTIVE DAYS VERSUS FAR 121.471 LIMITED TO ANY 30 HRS IN ANY 7 CONSECUTIVE DAYS). I INADVERTENTLY OVERLOOKED THIS. ON OCT/THU/99, I FLEW 1.7 HRS. THE AIRLINE SCHEDULED ME (AND I ACCEPTED) FOR A TRIP STARTING ON OCT/FRI/99, THAT WAS 3.3 HRS FLT TIME. I WAS THEN SCHEDULED FOR (AND I ACCEPTED) A TRIP STARTING ON OCT/SUN/99, AND ENDING ON OCT/THU/99, WITH 26.7 HRS FLT TIME. THIS PUT MY 7 DAY TOTAL AT 30 HRS (3.3 + 26.7 = 30 HRS) PRIOR TO STARTING TRIP. SOME LEGS ON THE 5 DAY TRIP TOOK LONGER THAN SCHEDULED DUE TO ATC DELAYS ENRTE, AS A RESULT OF WHICH MY 7 DAY LIMIT WAS EXCEEDED BY 1.2 HRS (3.3 + 27.9 = 31.2 HRS). THE AIRLINE FAILED TO NOTIFY ME OF THIS POTENTIAL EXCEEDANCE AND I INADVERTENTLY DID NOT CATCH IT UNTIL AFTER THE TRIP WHEN TOTALING MY LOGBOOK.
