April 2, 2011 Crash Yukon

[KenoraPilot]

Does anyone have any information on the Crash of the DHC3T in Yukon. Was a good friend who didn't make it. Condolences to his family. RIP my friend.

Yes I do, and I am not going to post it on a public website. If he was a good friend then get on the phone and call the family and speak to them.

Leave the gossip and speculation to the little people

A bunch of phone calls from random pilots is the last thing the family needs at this point. I too knew the driver involved. RIP

The lack of any info posted on here surprises me.

I don't see how there is any rumour or speculation going on at the moment.

[KenoraPilot]

Yes, the family doesn't need extra phone traffic right now. If anyone who has SERIOUS knowledge please PM me. I also am not interested in gossip.....I just want to know happened to my friend.

kenora pilot....I am not sure what you meant by SERIOUS Konwledge., but check your pMs

The aircraft did break-up in flight after having departed from cruise altitude. At the time there had been at least two previous Single Otter crashes due to in-flight break-up as a result of flutter. Possible related items of note were mentioned in the report including an aileron balance turnbuckle that had not been lockwired(but appeared to be functioning properly), the fact that despite having had the original piston engine replaced with a Garrett, the STC holder did not reduce the Vne from the original redline speed to the top of the green arc(even I know that this is a requirement), and an incident that day of the aircraft striking an object in the tail area with subsequent unusual bang sound that came from the tail area while manually repositioning the plane. However, readouts from the GPS were available and it appears that it was a slow departure from cruise flight with gradually increasing speed which eventually led to the breakup when the aircraft reached a very high speed(likely in a spiral) rather than a sudden departure from controlled flight.

Additional information was that the pilot was working an extremely busy schedule with over 60 flying hours per week in addition to assisting with aircraft loading and preparation. In fact, he was doing so much flying that he was exceeding the maximum allowable hours and falsifying flight times in order for the records to appear legal(the GPS recorded longer flight times than what was recorded). In addition, the airplane did cruise above ten thousand feet while enroute. The pilot did recently have ECG results of a heart murmur(nothing unusual was found in the autopsy).

Is it possible that the pilot was extremely tired and just fell asleep?

Wow...... you certainly must enjoy your time on this site commenting on an accident that happened 14 yrs ago and last post on here about that crash was 14 yrs ago,stats indicates 376 comments per year over your 20 yr period. No doubt you are the Top Gun of commentary, having said that it is a public forum and you got every right to your views. Nothing derogatory meant, just an interesting observation.

Hi,

I fell way behind on reading TSB accident reports. I print them off and once read, they go into a storage room. There is a pile for NTSB, TSB, AAIB, and foreign reports. A few months ago, I checked the TSB pile and saw many missing reports dating back to 2011. So, I decided to slowly start reading them in chronological order. When I read one, I check this forum to see if there was a thread on the accident. In this case, there was one that never had a conclusion. I kind of like to see some sort of conclusion.

A person might start perusing the forum and see a bunch of accident threads that leave them without sufficient available facts and it could be facts that will somehow make a safety difference on a future flight.

The reasons for airplane accidents can still be relevant to today’s flying, even half a century later. I see no reason to avoid posting about an accident 14 years ago. All airline pilots would do well to be familiar with the Eastern Airlines Everglades crash and the United DC-8 crash in Portland, both in the ‘70’s.

There is a very busy airplane accident thread that I discovered on Pilots of America. Because there are many old threads, sometimes I am reading a very dated one. It is nice when one isn’t just left hanging as to cause but can quickly get not only the initial comments and then the conclusion, instead of having to do a time-consuming search. Frequently, other pilots will see the accident report and provide valuable commentary that could save my life. Let us know if you have any.

Because of my chronological reading habits, one can expect some more old threads to be resurrected.

As for amount of posts I make, thanks for providing the stats. I suspect that there are others posting significantly more than I am per day, although they may not have been on the forum as long as I have.

We will never know what really happened, but I do know that a son lost a loving Dad that day. Tragic.
