I wanted to add to my earlier comment about a POI "interpreting" the flight thme limits to "allow" a ferry flight before a revenue leg which would otherwse exceed flight time limits.
It is not legal. Your POI has no authority to make that "interpretation". FAA policy on the issue is well established, and there is no ambiguity, question, or grey area. If you're on a ferry flight, that flight time must be considered for any subsequent revenue flight. Period. With something this black and white (and obvious), "My POI said it was OK" is probably *not* going to protect you in an enforcement action.
I've posted below two official letters of interpretation from the FAA's Office of Chief Counsel which address the same question for 135 and 121 operations. They are pretty clear, and if your POI is telling you differently, he is wrong.
Now a letter addressing the same question in Part 121 operations:

FAA Legal Opinion:

This is in response to your request for an interpretation dated August 6, 1992.
You ask what conditions must be met for a flight to be conducted under FAR Part 135 versus Part 91. You give the following example:
A flight is dispatched from Memphis to El Paso to pick up freight and deliver to Kansas City. The flight then returns to Memphis. The leg from Memphis to El Paso is empty. The leg from El Paso to Kansas City carries cargo. The leg from Kansas City back to Memphis is empty.
You then ask:
If the "assignment" is to fly from Memphis to El Paso to Kansas City, then back to Memphis, are the flights from Memphis to El Paso, and from Kansas City to Memphis considered operations conducted under Part 91 or Part 135?
Additionally, you state:
The company will sometimes dispatch a flight with enough duty time to get to a destination (i.e., Memphis to Newark, NJ) and then want the crew to Part 91 the aircraft back to Memphis or "re-position" the aircraft back to its base. Can this be done simply because the aircraft is empty, or must other conditions be met (i.e., non-revenue versus revenue)?
Section 135.1 provides in pertinent part that:
(a) Except as provided in paragraph (b) of this section, this part prescribes rules governing -
(3) The carriage in air commerce of persons or property for compensation or hire as a commercial operator...
(b) ...this part does not apply to - ...
(3) Ferry or training flights....
A ferry flight is defined in the Airman's Information Manual (AIM) glossary as:
- A flight for the purpose of:
1. Returning an aircraft to base
2. Delivering an aircraft from one location to another
The issue is whether the Part 135 flight or "assignment" is completed when the cargo is unloaded at the destination airport. The purpose of the flight conducted under Part 135 is to deliver freight to the destination airport. The ferry flight to return the aircraft to the base of operations changes the purpose to re-positioning the aircraft under Part 91. A flight conducted for the purpose of re-positioning an aircraft under Part 91, after the completion of an assigned flight conducted under Part 135, cannot be considered a new assignment under Part 135 and, therefore, is not subject to the flight time limitations and rest requirements of Part 135.
The general rule with respect to flight time limitations of Part 135 is that any "other commercial flying" (e.g., flights conducted under part 91) must be counted against the daily flight time limitations of Part 135 if it precedes the flight conducted under Part 135. However, 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.
The first leg from Memphis to El Paso delivers an aircraft from one location to another. It repositions. It is a ferry flight conducted under Part 91. However, because it precedes a Part 135 leg, flight time accumulated on the first leg must be counted toward Part 135 flight time for the 24 hour period.
The second leg from El Paso to Kansas City is a cargo flight conducted under Part 135.
The third leg from Kansas City to Memphis is returning the empty aircraft to home base. It is also considered a ferry flight conducted under Part 91. Because the flight time accumulated on the third leg occurs after the Part 135 flight is completed it does not count against Part 135 flight time limitations for that 24 hour period.
All Part 91 commercial flight time is counted against the pilot's quarterly and yearly flight time limitations. However, please note that if, for example, the pilot has reached the yearly flight time limit for Part 135 operations, the pilot can nonetheless continue to fly under Part 91 in that calendar year. "Other commercial flying" under Part 91 is counted to the calendar year limit only if a subsequent Part 135 operation is conducted in that calendar year. We enclose a copy of an interpretation dated October 9, 1990, issued to Mr. Steve Wolff. That interpretation concerns Part 121 operations, but the analysis concerning yearly flight time limitations and other commercial flying is applicable here.
The general rule regarding rest requirements is that if the Part 91 flying is assigned by the certificate holder, it may not be conducted during a required rest period. Since your example involves a Part 91 operation, required by the certificate holder, it may not be conducted during the required rest period and, therefore, may affect the availability of the crew for the next Part 135 operation.
You also ask a question regarding rest periods. You state:
(deleted this portion as it dealt with rest periods and was not relevant to the question at hand)
This interpretation was written by Thomas Kiely and Arthur E. Jacobson of the Operations Law Branch, AGC-220. It has been reviewed by Joseph Conte,
Manager of the Operations Law Branch and it has been coordinated with the Air Transportation Division of the Flight Standards Service .

Now a letter addressing the same question in Part 121 operations:
FAA Legal Opinion:
"January 13, 1992
(no name given)
This is in response to your request for a legal interpretation, based on a request from Hawaiian airlines, whether that carrier's interpretation of the "12 in 24" role in subsections 121.521(a) and 121.523(a) of the Federal Aviation Regulations (FAR) is correct. Hawaiian airline's position is that a flight crew may fly up to 12 hours in duration under Part 121 and then ferry an empty aircraft under Part 91. For the reasons stated below, Hawaiian airline's position is correct.
The applicable sections of the FAR state:
FAR 121.517 states:
No airman who is employed by a supplemental air carrier or commercial operator may do any other commercial flying, if that commercial flying plus his flying in operations under this part will exceed any flight time limitation in this part.
FAR 121.521 states:
(a) No supplemental air carrier or commercial operator may schedule an airman to be aloft as a member of the flight crew in an airplane that has a crew of two pilots and at least one additional flight crewmember for more than 12 hours during any 24 consecutive hours.
FAR 121.523 states:
(a) No supplemental air carrier or commercial operator may schedule an airman for flight deck duty as a flight engineer, or navigator in a crew of three or more pilots and additional airmen for a total of more than 12 hours during any 24 consecutive hours.
FAR 121.521(a) and 121.523(a) limit an air carrier from scheduling a crewmember for more than 12 hours during any 24 consecutive hours. FAR 121.517 prohibits a crewmember from doing any other commercial flying, if that commercial flying plus their flying in operations under Part 121 will exceed any flight time
limitation in Part 121.
A Part 91 ferry flight constitutes "other commercial flying." "Other commercial flying" however, is considered only when determining whether a subsequent Part 121 flight may be conducted. Thus the time spent on a ferry flight flown between two Part 121 legs would be counted towards the flight time limitations under FAR 121.521(a) and 121.523(a). If, as in this case, Part 121 flying does not follow the "other commercial flying," then the Part 121 limitations applicable to a period of 24 consecutive hours do not apply.
We hope this interpretation satisfactorily responds to your inquiry.
Sincerely,
Donald P. Byrne
Assistant Chief Counsel
Regulations and Enforcement Division"
