Narrative:

I was assigned to fly two different crews in 8/88. I accepted the assignment because my understanding of far 121 was that a crew member can fly up to ten hours in a 24 hour period. The 2 crews flown totaled 9.6 hours of scheduled block time. Discussion of this topic with other crew members and pilots after the fact shows a difference of opinion. Some pilots said 10 hours in 24 is allowed, others said only 8 hours in 24 is permitted. Therefore this report is being filed in case the 8 hour rule is correct.

Original NASA ASRS Text

Title: SUSPECT MAY HAVE EXCEEDED 8 IN 24.

Narrative: I WAS ASSIGNED TO FLY TWO DIFFERENT CREWS IN 8/88. I ACCEPTED THE ASSIGNMENT BECAUSE MY UNDERSTANDING OF FAR 121 WAS THAT A CREW MEMBER CAN FLY UP TO TEN HOURS IN A 24 HOUR PERIOD. THE 2 CREWS FLOWN TOTALED 9.6 HOURS OF SCHEDULED BLOCK TIME. DISCUSSION OF THIS TOPIC WITH OTHER CREW MEMBERS AND PLTS AFTER THE FACT SHOWS A DIFFERENCE OF OPINION. SOME PLTS SAID 10 HOURS IN 24 IS ALLOWED, OTHERS SAID ONLY 8 HOURS IN 24 IS PERMITTED. THEREFORE THIS RPT IS BEING FILED IN CASE THE 8 HOUR RULE IS CORRECT.
