Dear Mr. Jacober:
Thank you for your letter of April 10, 1991, requesting an interpretation of the
flight time limitations and rest requirements found in Part 135 of the Federal Aviation
Regulations (FAR).
Issue #1
In your letter you state as follows:
135.263(d) addresses a flight that goes beyond flight time limitations due to
circumstances beyond the control of operators, but what about beyond the duty period
limitations? For example, a flight crew takes a customer/passenger to a destination
airport to conduct business. The flight leaves early in the morning, and one hour
later they arrive. The crew gets a day room at a local hotel, as the businessman
expects to be gone at least eight hours. When it comes time to leave, the businessman
is held up in traffic and is very late getting back to the airport. The trip home
will also be about an hour, but the crew is faced with the dilemma of exceeding
a 14 hour duty day. This crew hasn't worked very hard, but can they complete
this trip?
Answer
Section 135.267 does not contain an explicit limitation on duty time. However, section
135.267(d) does contain a safeguard against excessive duty time in the sense that
if duty time beyond 14 hours infringes upon the 10 hours of rest required during
the 24 hour period preceding the planned completion of the next assignment, then
the next assignment would not be in compliance with the regulation.
In the situation you describe, the crew would not violate the flight time limitations
contained in section 135.267(b) by completing the trip. However, before the certificate
holder could assign or the flight crewmember could accept a new assignment, the
new assignment would have to provide for at least 10 consecutive hours of rest during
the 24 hour period that precedes the planned completion time of such assignment.
Issue #2
Your letter also states as follows:
The company that I work for was certified last May (1990). Until recently, we
were given the impression that it was OK to ferry an aircraft Part 91 back to home
or another airport as long as the flight crew received adequate rest prior to the
next Part 135 trip. We are now being told that ten hours of flight time is the limit
no matter what. We believed that the crew could exceed the ten hours, as long as
they received the rest described in 135.267(e), and the flight time in excess of
ten hours was conducted under Part 91.
Answer
The rule with respect to flight time limitations is that any "other commercial
flying" (e.g., flights conducted under Part 91, such as ferry flights) must
be counted against the daily flight time limitations of Part 135 if such flying
precedes the flight conducted under Part 135. In contrast, if the Part 91 flight
occurs after the Part 135 flying, the Part 91 flight is not counted against the
daily flight time limitations of Part 135. Note, however, that the Part 91 flight
time will be counted against the pilot's monthly, quarterly, and yearly flight
time limitations.
Thus, you are correct in your conclusion that it is permissible for a flight crew
to ferry an aircraft back to home or to another airport (Part 91 flying) after Part
135 flying, even if the ferrying would put the flight crew in excess of the 10 hour
daily flight time limitation of Part 135. However, the flight crew must receive
the rest required by the regulation prior to the next Part 135 trip.
Issue #3
You say that you have recently been told that any flying done in the aircraft, whether
revenue (Part 135) or non-revenue (Part 91) is all commercial flying. You say that
previously this was not the case and that this is written in your operations manual.
You also say that you have been told that you, as an employee of Private Jet Services,
cannot use the company aircraft to your advantage without such use being considered
commercial flying. The example you give is as follows: if you use the airplane to
go visit a friend in another city prior to taking a trip out of that same city,
that your personal time between your visit and the scheduled departure would be
considered commercial duty and flight time.
Answer
"Other commercial flying" means any non-military flying as a required
crewmember, other than in air transportation, for which the crewmember is paid for
his or her services. Presumably, you are not paid for your flight time in going
to see a friend. Therefore, it would not constitute "other commercial flying"
within the meaning of the flight time limitations and rest requirements found in
the FAR.
In regard to your operations manual, we must advise you that we do not interpret
or give legal approval to air carrier operations manuals. This policy is based on
the following reasons: first, factual situations are not presented in such manuals;
and second, attempting to "approve" such manuals would be far too onerous
a task - as you know, there are thousands of Part 121 and Part 135 air carrier manuals.
However, an operations manual may not be inconsistent with FAR provisions.
Issue #4
Concerning the next issue, you state as follows:
At the sole discretion of the flight crew, for an early morning flight out of
some of the local airports, we had been previously advised by the FAA that the crew
could reposition early in the morning instead of the night before. That the reposition
time wasn't considered part of the duty period. The reason being that the crew
had the option of leaving the night before and getting ten hours rest in a hotel,
or staying home and getting better rest with less problems. The owner of the operations
only concern was that the aircraft and crew was in position for the flight.
Answer
Repositioning flights are governed by Part 91. As we have discussed above, the rule
with respect to flight time limitations is that any "other commercial flying"
(e.g., flights conducted under Part 91) must be counted towards the daily flight
time limitations of Part 135 if such flying precedes the flight conducted under
Part 135. In contrast, if the Part 91 flight occurs after the Part 135 flying, the
Part 91 flight is not counted against the daily flight time limitations of Part
135.
If you were advised previously that the crew could reposition early in the morning
without it counting as part of the duty period, you were advised incorrectly. Since
the repositioning precedes the Part 135 flying, the time spent repositioning the
aircraft must be counted against the daily flight time limitations of Part 135.
Issue #5
Your final question concerns section 135.269's requirement for adequate pilot
sleeping facilities on board the aircraft. You ask what type of aircraft the Federal
Aviation Administration (FAA) was thinking about when they addressed this rule to
operators as described in 135.1. You also ask whether reclining seats would suffice.
Answer
The FAA has interpreted "adequate sleeping quarters" as meaning a bunk
or berth; a reclining passenger seat does not suffice. No particular type of airplane
was part of the premise for section 135.269.
This interpretation was drafted by Sheila Skojec, an attorney in the Operations
Law Branch; Richard C. Beitel, Manager. It was then coordinated with the Air Transportation
Division of the Flight Standards Service at FAA Headquarters. We hope that it has
satisfactorily answered your inquiry.
Sincerely,
Donald P. Byrne
Assistant Chief Counsel
Regulations and Enforcement Division
