Horizon has now grounded all Q400 with over a certain amount of cycles in response to SAS incidents. Seems they are joining OS and I am sure others. Maybe this will open up Bombardier eyes since there rep is to not help carriers with issues.

I just watched the story on KPTV here in Oregon-apparently, over 100 flights have been cancelled today. Glad I'm not flying QX this morning.

The guys on KPTV seem to be leaning towards Bombardier as the party grounding the aircraft-wonder if this is an emergency AD (airworthiness directive)  scratchchin 

As an aside, I've always thought that the Dash 8 had unnaturally long landing gear, but then again, so do the Rockwell Aero Commander and the Fokker F.27, and yet they haven't (to my knowledge  Wink ) had problems with main gear collapsing.

That will cause some real problems in the Pacific Northwest. Do you have any idea how many planes have been grounded? A 100 flights is a lot to be cancelled so far, but that isn't the entire Q400 fleet.

I hope other forms of transportation are available. I presume a lot of people will be driving. It's unfortunate that United Express out of SEA is just a fraction of what it once was and doesn't even really compete with QX anymore.

This was as a result of a Bombardier recommendation. They have requested all frames with more than 10k cycles be grounded pending investigation.

It's not an AD as of now. However, Bombardier has issued an All Operator Message that "highly recommends" inspection of all landing gear with more than 10,000 cycles before further flight. It wouldn't surprise me if that becomes an emergency AD today or tomorrow.

So far, I count 16 cancelled arrivals and 17 cancelled departures at PDX. Really not bad all things considered. Impacted routes from PDX are SEA, BOI, YVR, GEG, SFO, SJC, SMF, RDD, RNO.

There are also a couple of hefty delays on flights later in the day, the worst being a midday Seattle Shuttle departure that's showing a 1hr20m delay, a early PM arrival from BOI that's 2h30m delayed, along with a couple of 45min delays. (A 1hr20m PDX-SEA delay seems silly - you can drive halfway there in that time, but I'm sure it has to do with positioning for follow-on flights.)

Looks like they are ferrying the Q400 sitting at ACV right now up to Spokane within the next hour.

This morning's ACV-RDD-LAX and LAX-ACV-RDD-PDX are canceled.

There is a maintenance base in GEG? I thought the main MX base was in PDX?

It appears another is ferrying YYJ to PDX right now: http://flightaware.com/live/flight/QXE803

Are they also ferrying a CR7 from DEN to BOI for stranded pax? http://flightaware.com/live/flight/QXE9850

According to the Web FIDS at flypdx.com, AS has these extra sections scheduled today to/from PDX:
7245: PDX-BOI
7295: SEA-PDX
7296: PDX-SEA
7229: SEA-PDX

This is definitely hitting QX's overall operation, as we'd all expect. Now seeing lots of 2h30m+ delays on the Seattle Shuttle flights that are still scheduled to operate. One shuttle arrival from Seattle is 3h45m delayed. A RNO flight also has a 2h delay.

Even still, pretty impressed that QX is doing as well as it is under rough circumstances. According to FlightStats, QX is running 89% on-time for departures and 93% on-time for arrivals so far today, despite 114 cancelled flights (as of 11:30am PDT). I think that's pretty remarkable, and shows how hard they're working to keep things as smooth as they can...

I am just coming off of my weekend, so today begins my new work week. I found out about the groundings when I logged onto our internal website to check email...

As of now, I will not be able to find out more until I get to work at 8 tonight. If I can, I will certianly provide details on the inspections and what is the suspect parts.

All of the mechanics at SEA loathe the Q400 due to the extra work they make for us. I guess it is job security.

Well assuming what Horizon uses them for, you can figure an average of maybe 7 cycles per day. That would be about 50 cycles a week, which equates to about 2600 cycles a year. So you would figure a little less than 4 years. But this is just a real rough estimate, and doesn't count C checks and stuff like that. But I would think it would get pretty close despite that.

Well, if an aircraft requires gear swings, we try our hardest to ferry the plane to PDX. It is a pain in the a** to do that kind of work in SEA as we do not have the manpower or proper facilities to do the job. In a worse case scenerio, we will do it, with manpower assistance from PDX. As for the jacks themselves, just picture a 737 tail jack, and you have our wing jacks...

Some Q400's came and left BOI this morning. One left very early and said that they would be "gear down" for their flight to GEG...thought that was interesting (QXE801, I believe). It was pretty slow today in BOI without the Q4's. I remember a DH8B coming in this morning and leaving but never returning.

Yeah, that must have been one of the 19 planes over 10K cycles that was ferried or grounded for mx. This left QX with 14 Q400's to cover a lot of ground. And if you add in that they are the a/c of choice on some long flights (West Montana, BOI-LAX,etc). It sure left QX in a pinch. But I think QX and AS did a good job dealing with the problem. I know many Bay Area pax had been rerouted already when I arrived at 5am.

That does not count Q400s that are down for other mx issues. At last look, there were 24 of 33 Q400 out of service. That is big chunk of the fleet right there... QX must be inspecting the entire fleet, not just the high time ones, as a few of the new aircraft are down for gear inspections (delivered in the past few months).

Correct. This was going to happen as soon as Transport Canada issued their AD. All Q400s were going to require a MLG check before their next revenue flight. When necessary, the aircraft will ferry to a maintenance station for the inspection and then be redeployed into revenue service. To be clear, this was only for the aircraft that were *not* part of the original 19. Those 19 are still awaiting more detailed instruction from Bombardier on what the inspection will entail and how long it will take for them to enter revenue service again.

As has been mentioned, it was on the advice of Bombardier that higher cycle aircraft were grounded. All carriers with frames with over 10,000 cycles were affected.

Later this afternoon, it was also recommended that further checks be performed on lower cycle frames too.

Up here in Canada, Porter Airlines' Q400 fleet (4 frames - the oldest having around 2,000 cycles) was inspected (again), simultaneously at around 3:30pm EDT in accordance with the second communication from Bombardier & Transport Canada.

I had heard that the newer frames have a slightly different gear design which isn't thought to be affected... well, they certainly don't suspect it, since they only grounded those with over 10,000 cycles (the two planes involved with SAS both had around 14,000 cycles if I'm not mistaken).

Could be an interesting few days ahead for Q400 operators.

"Anyone see Porter Air grounding their fleet???"

PD's fleet was inspected visually at least twice on Wednesday, in accordance with advice from Transport Canada and Bombardier. As I mentioned earlier, all four aircraft were inspected simultaneously (2 in Toronto, 1 each in Ottawa and Montréal) in the afternoon.

So far, there's no indication that a grounding is likely or imminent... whatever it was they were looking for, they didn't find any signs of, and the fleet has continued in regular service ever since. Ticket sales (very briefly suspended for travel on Wednesday, as a precaution) have continued as normal since then.

No indication yet as to what exactly they were looking for, but it's a positive sign that they haven't found it.

Long live the Q400.  airplane

Actually SEA has been dead... I did two DVIs (Detailed Visual Inspection) of the MLG on two of our recent deliveries Wed night, and we were concentrating on the retraction actuator. The AD note for the high cycle a/c deals heavily with this component, but I have no idea what it calls out for specifically. I have not seen the paperwork yet, as the actual work on the critical a/c is being done in PDX or GEG. I have been told thought that it looks like it will become a recurring inspection item on the whole fleet of Q400s...

We are down to half capacity on the shuttle at the moment. A few of my coworkers here in SEA commute from PDX, and they have been stranded here because they have not been able to get a seat on a flight.
