The accident report is now out!
Transportation Safety Board of Canada - Aviation Investigation Report A12O0170
IMHO
This Accident Report as usual leaves a lot to be desired. It reeks of an under-investigated accident.
The problem with accident reports is that more often than not,
political consequences determine what will be included or omitted from the report.
This report has several parts to it that raise the question that there might be others who
may have information that would shed a light on how and why this accident occurred.
Alarm #1. He flew from the right hand seat when it appears no sane person would do that. Why? I would speculate that its not the first time he did that.
Alarm #2. He took off knowing that he did not have the Oxygen bottle turned on and it was unavailable without landing and turning it on. He chose to fly with it OFF.
These two decisions show that something was wrong with his mental abilities that were most probably related to his ongoing and escalating medical problems.
Then there are his medical problems and a serious weight problem. To be blunt, his life expectancy just watching TV was very much on the short side, so much that it begs the question as to the incredible decline in medical standards that have occurred over the years.
I recall one transport inspector, had a heart attack and was back flying shortly thereafter. The stress that triggered that heart attack was still there.
Flow Control Shutoff Valve (FCSOV) was off. With 5 reasons for the valve being closed, how and why would he ignore the aural and visual warnings?
Did you deliberately choose to fly unpressurized? - Probably not, he knew what the time of useful consciousness was, he knew his medical problems but most probably underrated them.
Speculation.
I'll guess that he was taking medication that we did not know about, that his medical problems were worse than what most people knew. I'll guess that there is another doctor who prescribed medication that we don't know about.
I'll guess that his ability to fly was severely compromised before he started the engine and made a series of mistakes that may be due to being hypoxic when he took off and in the first few thousand feet and by the time ...
From 12:04 at 7,000 to 12:16 at 25,000 is 12 minutes and with that rapidly increasing altitude cam rapidly decreasing useful consciousness.
The sudden obvious loss of control could well be a combination of problems and then what is really disturbing is all the witness reports of loops, inverted flight etc.
It appears that the final cause of this accident was disorientation caused by the hypoxia and his medical problems that led to the decisions that caused the hypoxia.
