Russia's MAKS 2011 air show closed with an embarrassment for Sukhoi, when the pilot of its second prototype PAK-FA/T-50 was forced to abort a take-off run after two bursts of flame erupted from the fifth-generation fighter's starboard engine.

The incident happened in front of about 200,000 visitors, who had gathered at Ramenskoye air base near Moscow on 21 August to watch a flying display.

Also referred to as T-50-2, or Side 52, the aircraft was forced to stop from a speed of around 100km/h, with Sukhoi test pilot Sergei Bogdan using wheel brakes and also deploying a brake parachute.

It stopped well short of the aerodrome fence, thanks to the 5,000m (16,400ft) length of the runway.

Sukhoi said the aircraft had suffered a technical malfunction but no damage, and that its pilot had acted "in accordance with manuals".

The company later attributed the issue to a "malfunctioning fuel supply system" and to the NPO Saturn Item 117 engine's full-authority digital engine control system.

To further Sukhoi's embarrassment, immediately after the incident the show's organisers promised the public that the first PAK-FA prototype would fly instead. This failed to happen, with the aircraft believed to have been sent for maintenance shortly after performing in front of Russian prime minister Vladimir Putin on 17 August.

Well its embarrassing only because it happened in front of the media in an air show. Such things happen otherwise particularly because its a new bird. Come out stronger from it and carry on.

Still got to give it to the russians, Pakfa pulled 5Gs after 1.5 yrs of its first flight. I think no country has done it.

I don't know why it should be embarrassing. This is quite common occurrence in military aviation & keep in mind this is just a prototype. The F-22 crashed in its development phase. Compared to that a flame-out is nothing.

Thank GOD it was not the Tejas right? We would all know what will happen if it was the Tejas! :whistle:
There is a huge difference between how much I know and what you know.

Even if LCA had done it in it's first flight using the Kaveri engine, this would have been nothing.
It's like a kick back when you use the kick start on motorbikes. Very normal.

Sh!t happens, so grow up.

The flameout means nothing to the T50 itself, but it certainly ruined the advertisement.
