Proof of why CBC should be defunded - a terrible and sensationalized story, particularly since the official report has been available for over 3 months. Not surprising in a sense at Terrence McKenna got caught by veterans a few years ago exercising less than honest journalism.

What are you talking about? This episode was relatively well done (small nuance errors) as it's objective was to convey the technical issues to Joe Public with an emphasis on the human element. You think the AA Captains were sensationalizing or explaining? It was not as sensational as other media reports. The episode has nothing to do with politics or CBC.
What’s wrong with this news piece? Allow me to explain.
First, bear in mind that this was aired fully 3 months after the Indonesian accident report was released.
Here is what I really don’t like:
- The simulator assessment was a little bogus. It is well known that the APA pilots (this guy in particular is a little annoyed about the lack of MCAS info. Offended is probably a good way to put it.
- The airspeeds and altitudes were not were not “wildly wrong” at all. They disagreed by a few knots and feet, repectively.
- Startle factor. Ok, there is a startle factor, not doubt about it. But they Lion Air accident Captain overcame that and called for the Airspeed Unreliable drill. He didn’t now it so he asked the FO to do it. He didn’t know it either and the transcript reveals the sound of pages turning. Finally, the Captain says “10.2”, i.e. page 10.2 of the checklist. These are memory drills and were never done before the flaps were retracted and the “beast” MCAS kicked in. Moreover, how is it that the crew of that same aircraft the previous day with the same problem overcame the “startle factor” and did the drill (and flew the aircraft for an hour and a half with MCAS)?
- Lots of drama about the nose down pitching with MCAS activating. But how is it that the Captain of the accident aircraft managed to manually trim the aircraft to neutral 26 times before handing control to the FO who promptly lost control of the aircraft? How is it that the crew of the incident aircraft the previous day not only controlled the longitudinal trim of the aircraft but they also recognized it as a stab trim runaway, did the drill (turn off the stab trim) then flew the aircraft for an hour and a half to the destination?
- The AA pilots were offended about not being informed about MCAS. Fair enough. But would it have changed the outcome. The Lion Air accident crew could not do the unreliable airspeed drill by memory nor could they do the stab trim runaway drill, despite the trim running away 26 times. Following the Lion Air accident, all MAX pilots were informed about MCAS, including the Ethiopian pilots. I didn’t change the outcome did it?
- 4 seconds to recognize a failure and 10 seconds to react. Ok, so how did the Lion Air incident crew do it? The Lion Air accident crew flew the aircraft for minutes after the MCAS did its thing – the had plenty of time to react, 26 six times the aircraft was retrimmed to neutral then MCAS pitched the aircraft nose down. They could have had all day to react but they never were going to get it right because they were never going to recognize this as a stab trim runaway and turn off two switches on the center console. Same for the Ethiopian crew.
- The accident report describes the decision process in allowing MCAS with a single sensor. Boeing assumed that type-rated pilots could do a UAS drill and a Stab Trim Runaway drill. Bad assumption.
- And, yes, that meant no requirement for extra simulator training as these are well known emergencies, the Stab Trim one going back to the 707 days and present on every Boeing since. The UAS drill has been in existence for years too. Yet, despite all of the neither the Lion Air accident crew nor the Ethiopian did them (although the Lion Air incident crew did).
- The Ethiopian crew only had 10 seconds to perform the procedure? B.S. McKenna is quoting that figure out of context. They had plenty of time as they were airborne for 6 minutes and not during any of that did anyone do the UAS drill and at least pull the throttles back to control the aircraft. Even worse, they turned the Stab Trim back on!
- I could go on about the public hearings, etc.
Don’t get me wrong. I am not a heartless SOB; I have every sympathy for the victims and families. I have lost enough friends in airplane accidents to know how they feel.
I am pissed off as a professional aviator as these accidents were entirely preventable, as the Lion Air incident proved. I am pissed off with the regulators in these countries for not regulating; the airlines for providing crappy training and not insisting on their pilots to manually fly their aircraft (as their manual flying skills were non-existent); and, yes, the pilots for not knowing their emergencies drills. If the accident aircraft crews had done nothing but pulled the power back from take-off thrust and controlled the airspeed of the aircraft, neither of these accidents would have occurred. But they couldn’t even do that.
Boeing makes great airplanes and, yes, Boeing is culpable for these accidents with the crews, the airlines, the regulators, the maintainers, and the component overhaul shop. But this documentary does not reflect this story accurately and completely. But that is Terrance McKenna’s style.
