Hi all.

Newbie question for the beasler.

I have read the FAR's for the various Parts, but I have never found a layman's explanation of them. Part 91 is what I do (did) so I understand that as I do Part 141.

What I am looking for is not regs, but simple examples.

i.e. When I see...


  1. UPS or FedEx landing at MCO I am seeing part ?
  2. When I see Southwest landing at MCO I am seeing part ?
  3. Robert at Flight Express works for a Part ? outfit?
  4. Sven, on call in the Citation is part ?
Thanks in advance.

p.s. I did a search on JC for this and did not find anything.
 
UPS, FedEx, Southwest are Part 121. Flight Express would be Part 135 and Sven on call in the Citation would be Part 91...I think. Don't quote me on that. I probably have no idea what I'm talking about. :laff:

Interesting, the 121 ops seem so disparate--I was thinking pax and cargo....seems to be not the case.

Thank you.

UPS and Fedex are part 121 for their larger jets. A caravan in Fedex colors will most likely be part 135. An ATR in Fedex colors I believe operate under part 121. What part the aircraft operates on in this case is dependent on the weight of the aircraft.

Southwest operates under part 121. There used to be some airlines such as Colgan who used to operate under 135. But now I believe most airlines operate under 121. It was also dependent on weight.

Corporate aircraft gives you a mixed bag. A BBJ/corporate RJ may be part 121. Some corporate aircraft operate under 135, while others operate under Part 91. Fractionals operate under part 91 K.

Clear as mud.:)

Thank you.

I used to think it was all so regimented, but now I see it is a muddle; That helps.

Thanks.

Thats why I put most likely. You can operate part 91 if you're empty.:)

Eh...Depends.

I think there's an interpretation out there saying that if you're repositioning at the cost of the customer, it's still 135...even if empty.

I'll see what I can find. I've read so much crap lately that multiple crapness could be combining in my head. It's happened before. I need some pie. mmmmmmmmmmmmmmmmmmmmm

Well, from my understanding is that the big distinction between 135 and 121 is scheduled v. unscheduled operations as well as aircraft size. Part 121 is for domestic flag carriers and 135 runs for commuter and on-demand operations. You can look at the part 119 definitions to see how that plays out.

What does 'Flag Carrier" mean?

Mostly just aircraft size. You can run a 135 scheduled "airline" just like a 121 airline, but you can do it single pilot if you want if the aircraft is single pilot certified.

I think the cutoff for part 135 is 19 pax seats or 7500# payload...someone correct me on that if I'm wrong, it's been a while.

That's what I remember seeing for the size cutoff, mini.

b, from the FARs:

Flag operation means any scheduled operation conducted by any person operating any airplane described in paragraph (1) of this definition at the locations described in paragraph (2) of this definition:
  1. Airplanes:
    • Turbojet-powered airplanes;
    • Airplanes having a passenger-seat configuration of more than 9 passenger seats, excluding each crewmember seat; or
    • Airplanes having a payload capacity of more than 7,500 pounds.
  2. Locations
    • Between any point within the State of Alaska or the State of Hawaii or any territory or possession of the United States and any point outside the State of Alaska or the State of Hawaii or any territory or possession of the United States, respectively; or
    • Between any point within the 48 contiguous States of the United States or the District of Columbia and any point outside the 48 contiguous States of the United States and the District of Columbia.
    • Between any point outside the U.S. and another point outside the U.S.

I know there's something about 19 seats somewhere, I just can't remember what exactly it is. Heh.

I think maybe that's the cutoff point for an FA...I thought it was the 135-121 dealio, but looks like it's 9 pax seats.

More research would be required but I'm up to my elbows in delicious Pop Tarts.
