Russia plane crash kills two, injures dozens in Siberia Plane skids off runway in Russia's Buryatia region before slamming into a building and catching fire. 
Officials say all the passengers were safely evacuated from the plane before it was destroyed by fire [Ministry of Emergency Situations for the Republic of Buryatia press service via AP]

A small passenger plane has skidded off a runway in eastern Siberia, killing two crew members and injuring dozens of passengers.
The An-24 plane carrying 48 people, including five crew members, experienced an engine failure and crash-landed in the town of Nizhneangarsk on Thursday morning, Russia's top investigation body, the Investigative Committee, said in a statement.
The jet overshot the runway, slammed into a building and caught fire in the town on the northern shore of Lake Baikal. Footage from the scene showed the plane lying on its belly with the nose broken off.
Officials said that a pilot with 34 years of experience and a flight mechanic died while the other crew members survived.
The Buryatia governor had previously said both pilots had died.
The aircraft had taken off from the regional capital of Ulan-Ude and flew to Nizhneangarsk, where it was forced to make an emergency landing when one of its engines failed, regional officials said.
"All 43 passengers were promptly evacuated. There were no victims among the passengers," Angara Airlines said in a statement. The airline appeared only to be referring to deaths.
More than 30 people have been injured, and nine were taken to hospitals with severe burns and other injuries, said Alexei Fishev, spokesman for the local governor.
Investigators say they have launched a probe into what caused the crash of the An-24 which is a mainstay of Russian aviation

The information above may be incorrect. According to what I'm reading, it didn't overshoot the runway but rather veered off after landing. It may (or may not) indicate that the pilots simply forgot they have one engine inop and pulled both reverse levers. But that's nothing more than speculation until we have the IAC's report.

Is this aircraft designed so that it can still fly adequately with just one engine operating?

Whatever the cause, it's a shame that the pilot and mechanic lost their lives. R.I.P.

I cannot connect the dots from watching the video. If the left engine (No 1) had failed why did it pull to the side of the good engine! Also the aircraft never seemed to decelerate and the engine sound remained almost constant. The video appears to also show that the pitch on the blade didn't flatten or vary after touchdown.

On
, there is a remarkable trail of white smoke behind the right main landing gear, starting nearly immediately after touchdown.
briefly shows the right wheels in a rather shredded state (at about 0:50), albeit already after the runway excursion started.
Those two points might well be connected to subsequent lateral control issues on the ground: if the wheels on one side have failed and soft(ish) ground is entered, there may well be a big imbalance turning the aircraft to the right, as has obviously happened.
Unfortunately, technical drawings of the An-24 are hard to come by - but maybe there is somebody around here familiar with the landing gear and brake installation on the An-24? Does the failure of engine #1 affect the operation of the hydraulic system and, consequently, the brakes? Is there a connection between an engine failure and a subsequent tire failure upon landing?

The white smoke is, imho, the locked tires trying to stop the plane. The cabin video showed shredded tires on the right.
The cabin video also clearly shows that reverse thrust wasn't applied at all. On An-24 when props are reversed the change in sound is very distinctive. The outside video shows smoke only coming from the right tire. Maybe that's what pulled it to the right. And pilots either didn't know the left brake was inop or simply had no choice but to keep pushing.

I thought it looked a tad fast too, but I'd be the first to admit that it's very difficult to judge accurately. If indeed fast, did it burst that starboard tyre on landing?
Larger version of the post-crash still picture above:

It does show the outer-right tire is missing, and I did note what could be flailing rubber in the video, although that brief section is so jumpy that I considered it unreliable evidence on its own.
Approach speed - I'd want to hear from someone with An24 experience. The wide-angle lenses on phonecams can distort or exaggerate ground speed. But it did look fast to me.
Touchdown is just past the second = runway marks - is that significantly long?
Nevertheless, the excursion to the right is probably the key event.

in fact, by looking at the landings of old russian birds you almost always see how they balloon and have almost 0 pitch right before touching down.

Of course, there are many western aircraft types that are known for their negative pitch during approach as well. Consider the CRJ-200, the DH8 in certain flap settings and other models (typically) without slats. Given the prevalence of such pitch values on these types, Occams Razor would rather seem to point to systemic or procedural reasons for them than to training issues affecting the entire world fleets.
is a video of an apparently normal An-24 landing that also displays a rather negative pitch during approach...
