Tu-95MS Bear - single mode of failure?
Mystified by two recent accidents of a probably very well tested military aircraft. What could be the reason other than catastrophic in-flight fire or mechanical brake up?
Anyone familiar with the bomber or these accidents?

Not aware of a single cause- and rarely are there single causes. This article Russian pilots of 'bear bomber' plane die after crash | World | News | Daily Express
includes: "but TASS news agency cited sources saying a failure of the plane's fuel valves led to the simultaneous failure of all four engines."
If you are asking about speculation on contributory causes they could include a host of items:
- Aging systems
- Maintenence
- Funding
- proficiency- crews, maintainence, support teams
- An uptick, or surge in flying. There does seem to be a surge.
Most likely a combination of several factors. Pushing aircraft and crews that have not been pushed for years; perhaps deferred maintainence; shortage of parts/funding.....could be a real recipe for problems.

I think the 'MS' varients were built in the 80s & 90s.
Production of the Tu-95MS continued at Taganrog to 1983, when production was transferred back to the Kuibyshev plant. It seems the last Bear was rolled out in 1994.

Caygill,
I think that the content of this thread is already pretty much covered by this one here on Pprune:
http://www.pprune.org/military-aviat...gns-age-2.html
Perhaps you should continue on that one, or get the two merged?

Thanks Biggus & sandiego89
Still rather confusing. We have a plane with an ”enviable reliability” (quote), based on Soviet-era design philosophy of total and multiple system redundancy, and a landing gear suitable for rough airstrips.

Dat, yes, many times over the years, especially in the 80s before they ran out of money.
A s glad rag says, getting close enough up underneath the Bear at night to read the door numbers (the only place the aircraft's number was displayed was on the nose gear doors) was a tricky game.

I recently listened to a pod cast with former RAF pilot Nick Anderson as the interviewee and he tells some stories about various interceptions over the Atlantic and North Sea. A night interception with a non cooperative Bear sounded a bit on the scary side especially in poor weather.
He gave the impression thst the Russians did not care what problems they caused civilian air trafic around the UK and the technology on those aircraft could be a little crude. I was wondering if the Russian "sod the world" attitude along with a poor safety culture may have contributed to the accidents.
One of his stories was about a Russian crew member trying to take a photo of his Phantom with a very old and large camera that took almost half an hour to set up. When this poor guy was almost ready the Phantom would just slide under the Bear to the other side and the game would start again. Sounds like those missions weren't all boring at all.

Thank you, Dat!
EDIT: 2:20 later, bloody good. It was a great interview. So, again, thank you for pointing me to it.

No problem.
Very entertaining for a non military type such as myself and gives a small window into the Cold War from a man on the frontline. You weren't on the "Girls School" were you Courtney?!

...a non cooperative Bear...
Sam Fox didn't know (at the time) the part her rather impressive parts played in perestroika / glasnost. The September 1985 page was particularly appreciated by the Ivans!
Too true, BEags!
Absolutely not, Dat. The Fighting Cocks both times, once on the F-4, once on the F-3.
