Re: Boeing Systemic Problems Continue

Can you share your source that the KC-46 was the genesis of the MCAS system? I haven't heard that before either, but the KC46 is basically a 767-300ER built on the 767-200 body, so it's certainly plausible that it suffers from some power/pitch anomaly that requires artificial stabilization... The 7...

Re: Boeing Systemic Problems Continue

I had read that the AOA comparator warning system was an option, but I'm pretty sure the MCAS still relied on a single AOA data source, regardless if the comparator warning option was installed. The comparator warning would give an additional clue to the crew in the event of false MCAS stab trim act...

Re: Boeing Systemic Problems Continue

The latest info from Boeing is that the fix is primarily software, and I did not know that the Max already has dual AOA sensors fitted. MCAS will now require AOA to agree before activating, etc. Odd that they didn't set it up that way to begin with.

Re: Boeing Systemic Problems Continue

The max is a bridge to far for the 737 classic architecture. Likely what it really needs is a completely new FBW empennage, something that would have required a new type designation.

Re: Boeing Systemic Problems Continue

That's interesting. I haven't been following the story lately. What about the fix will require new hardware and wiring? It remains to be seen what they are doing for the fix, but there was talk of having to go to dual AOA input and AOA comparator warning at minimum for MCAS. I’m not sure if this co...

Re: Boeing Systemic Problems Continue

I'll be curious to see the size and scope of the modification man hours required per fin. I suspect it will be more than a simple software load, and probably will involve hardware and wiring. Could be a bit of a holdup as well.

Re: Small plane crash near Kenora.

It seems to me that back in the days before CARS, that it was the AME's responsibilty to check an verify AD compliance on an annual, but I agree that this is no longer the case. It's unfortunate that in this instance, the owner just didn't go out and purchase new struts for a couple hundred bucks ea...

Re: Small plane crash near Kenora.

Gotta wonder about the mentality of some AME's running around signing off annuals on bug smashers like this without any due diligence.. Huh??? Why wonder about the AME's? It is the owners responsibility to determine airworthiness. If he doesn't direct or want the AME to do any AD research - it's no...

Re: Small plane crash near Kenora.

So if strut AD was not complied with, C of A was invalid, and likely had been for 3+ years? Gotta wonder about the mentality of some AME's running around signing off annuals on bug smashers like this without any due diligence..

Re: More grist for the F18 replacement mill..

Another issue nobody is talking about is the age of the RCAF A310 fleet. Those ex-wardair machines are now around 35 years old and must be on the verge of non-viable. I'd say a mixed 737-based fleet order of p8/wedgetail/BBJ would make economic and operational sense. Another plus is commonality with...

While there is no doubt that the hornets need to be replaced, if the government is serious about the arctic, they should be looking at some P8's and a few wedgetails to replace the Auroras as well as a deep water port. Better yet would be a made in canada solution like the BBD Global based surveilla...
