I flew ROC-LGA on US Airways 3943 operated by Air Wisconsin doing business as US Airways Express. Equipment was a CRJ-200. Interesting things happened, though: the #2 wouldn't start up. So we taxied out, and I think the captain said he tried a "cross-bleed start" (I assume it means using power from the first engine to start the other) and it didn't work, so we went back to the gate. Ultimately they canceled another flight (there's another CR2 that does BOS-ROC-BOS, and they canceled ROC-BOS) and gave us the aircraft. About 50 people who were losing their minds and not going to Boston. I think we got an additional four pax on our flight and they were gonna take the Shuttle from LGA. I asked the pilot a while later, he said he had no idea what the problem was, it just wasn't spinning up.

So, I turn it over to you all. Anybody have any information? I'd love to know. The aircraft was N421ZW, we were later put on N431AW.

Thanks!

(By the way, on the return I was supposed to fly EWR-PHL-ROC. The EWR-PHL flight got delayed and I was going to miss my connection, so they put me on a direct CO flight operated by Colgan. I was pleasantly surprised.  Smile)

If your asking why the engine would not start, I am not a mechanic. In my experiences in the past when this had happened on our 737's and on a DL L1011 I was on once, it was due to a bad starter valve. Apparently the valve does not open as it should and the cross bleed air cannot spin up the other engine. IIRC I seem to recall some of our mechanics would use a screwdriver on the 737's to manually open the valve, when troubleshooting the problem.

Again I am no mechanic, just going by my memory from my many years at my airline.

Could also be a sheared starte shaft, both ignintors failing, or a bad fuel control unit. Hard to say with any certainty without more information.

This is most likely a decision based on the operation as a whole. A couple of things are in play here. Ship 431 was originally supposed to do BOS-ROC round trips as you mentioned with 421 going to LGA. If you cancel the LGA and run BOS, then you are also affecting another flight out of LGA if not two (assuming a crew change in LGA), not to mention that line possibly puts the AC into the PHL or DCA market later in the day. By cancelling the LGA flight you are taking one plane out of LGA, and possibly cancelling a couple of more flights. By taking the plane from BOS-ROC, you are only cancelling one R/T, and the crew that is doing that R/T is still in ROC where they would be if they ran the R/T, and you don't take any ac out of LGA that would lead to additional cancels down the road.

I know it seems like a bad decision given the Pax that were involved, but by running LGA, instead of BOS, you are saving you self from much bigger headaches than a simple BOS-ROC R/T being cancelled.

Hope this helps.

That is correct. They said it was a "business decision".
By the way, we didn't have a crew change; same crew operated the LGA flight as originally planned. I think the a/c continued on to Norfolk, VA from LGA, if I recall correctly.

Does anyone have any (insider?) info as to what actually happened with 421? I'd really be interested in knowing.

I think he means that your aircraft N421ZW was supposed to have a crew change once it got to LGA. That means that whatever crew was supposed to run LGA-ORF would have had to have been recrewed as their flight (and line) would have wound up getting canceled had they not switched you all onto N431ZW.

That is exactly correct. And because the AWAC flight department has woefully understaffed the domiciles these days, reserve crews are at a premium. Anything that AWAC can do to avoid using them is done. Basically two things are in play here. The crews line after LGA, and the AC routing. Both are affected if you cancel LGA, which affects a lot more than a round trip. So really the only option you have there is to cancel the BOS-ROC round trip, which also buys MX time to send a Road trip up to ROC with mechanics, and you have the crew still in place where they were supposed to be anyways that was doing the BOS round trip, and all the LGA flying is protected.

One other issue in play is the LGA slots as well. They are use it or lose it, so anything that can be done to avoid LGA cancels is done, because if some slots go unused for a certain percent of the time, they are lost. Not exactly a good thing when Delta is hoping to get all of them.
