But couldn't they say we have 5 B717s in the shop right now thus they're undergoing maintenance thus per the PWA definitions section they're in the fleet and we can operate 4 CRJ900s?

Well this could get interesting. It is one thing for the JV with a foreign carrier to be expected to be out of compliance at a future date, this is a whole different deali-o. Frankly, this would be inexcusable. I am waiting for official word however, but this is something that has no reason to wait until the official "date" in order to be prosecuted.

I would advise to do some of that proactive **** Mav.... before this becomes a Waterloo.

I believe the language said they must be in service. Hangar queens do not count. IF I remember correctly.

EDIT: FLEET is defined in the PWA "Fleet" means aircraft in service, undergoing mx, AND operational spares.

So all 3 conditions must be met. Therefore tsquare is correct.

Had this happen too. Go into Icrew and under the first tab click on rotation. Type in rotation number and date and voila your new rotation. With probably an extra turn on out:)

one of up to 153 aircraft configured with 71-76 passenger seats and certificated in the United States with a maximum gross takeoff weight of 86,000 pounds or less (“76- seat aircraft”).
Exception one: If the Company establishes a fleet of new small narrowbody aircraft, the number of permitted 76-seat aircraft may increase on a one 76-seat aircraft for each one and one quarter new small narrowbody aircraft (1:1.25) ratio (rounded to the closest integer) up to a total of 223 76-seat aircraft. In the event more than 153 76- seat aircraft are in category A or C operations, then on January 1, 2014, and each succeeding January 1 thereafter, the Company will implement its plan to reduce the number of 50-seat aircraft in category A or C operations below 348 (the number 50-seat aircraft in category A or C operations as of July 1, 2012) rounded to the closest integer, as follows:
1) 2.7 50-seat aircraft for each of the first additional ten 76-seat aircraft (above 153),
2) 2.7 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 163),
3) 2.8 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 173),
4) 2.9 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 183),
5) 3.0 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 193).
6) 3.1 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 203), and
7) 4.6 50-seat aircraft for each of the next additional ten 76-seat aircraft (above 213).
Note one: Upon the delivery of a 223rd 76-seat aircraft, the number of permitted 50-seat aircraft will be 125 regardless of the number otherwise provided in Section 1 b. 46. f. Exception one.
Note two: If on January 1, 2014, or any succeeding January 1 thereafter, the number of 50-seat aircraft in category A or C operations exceeds the maximum permitted number, the Company will require carriers that engage in category A or C operations to suspend or cease operations on a sufficient number of 50-seat aircraft or 76-seat aircraft to comply with these requirements within 60 days and to remain in compliance thereafter. The Company will be excused from compliance with the provisions of this Note in the event a circumstance over which the Company does not have control is the cause of such non-compliance.

Definition 28: “Fleet” means aircraft in service, undergoing maintenance, and operational spares.
Here is the language in Definitions. If they ESTABLISH this category, then they can is how this reads.

The language says "established." There is no further explanation.

Exception one: If the Company establishes a fleet of new small narrowbody aircraft,
41 the number of permitted 76-seat aircraft may increase on a one 76-seat aircraft for
42 each one and one quarter new small narrowbody aircraft (1:1.25) ratio (rounded to the
43 closest integer) up to a total of 223 76-seat aircraft

Look under the definitions section. I know I had this concern when it was a TA and I found something that cleared it up. I don;t have the contract handy, and I really don't feel like going to the website and doing the research on the fly.

Correct. And nowhere in there does it state that 76 seaters can come without 717s coming first.

They conveniently skipped "established" in the definitions section.
