FAR Part 135 Crew Duty and Rest Times

Are You Properly Complying with the Rest Rule?

Safety is critical for the overall viability of the aviation industry. And high-quality training is the foundation for safety.

But FAA regulations governing FAR Part 135 crew duty and rest times have been a source of confusion for many operators over the past few years.

Fatigue is an important issue, and proper rest is necessary to prevent pilots from losing focus during flight. And some operators may need to update their training (whether online aviation training or classroom training) to stay current.

One of the biggest areas of confusion in FAR 135.265 lies within (b)(2) which states that pilots cannot fly during the 24 consecutive hours preceding the scheduled completion of any flight segment without a scheduled rest period during that 24 hours of at least 10 consecutive hours of rest for 8 or more but less than 9 hours of scheduled flight time.

Crew Duty and Rest Requirements Compliance

We find that many pilots and operators believe that the 10-hour rest period begins when they end their day and is completed after 10 hours pass before they accept their next assignment. However, if they’re on call during that interval, the FAA doesn’t consider it rest and they’re in violation of the FAR 135.265 (b)(2) rule.

Since “rest” is defined by the FAA as a “freedom from any obligation,” being on call isn’t considered rest – whether the pilot accepts an assignment or not.

Here’s more clarification from the FAA legal department.

Having a proper fatigue management program is critical for both safety and FAA compliance. Understanding how the FAA interprets FAR 135.263 is important – especially when operators with the best intentions may find themselves out of compliance.

FAR 135.265 Flight time limitations and rest requirements: Scheduled operations 

(a) No certificate holder may schedule any flight crewmember, and no flight crewmember may accept an assignment, for flight time in scheduled operations or in other commercial flying if that crewmember’s total flight time in all commercial flying will exceed –

(2) 120 hours in any calendar month.

(3) 34 hours in any 7 consecutive days.
