Hmm; that really didn't look like a barrel roll! 🤔

[Ninthace]

Nearly a cartwheel!

[cynicalint]

It did go west! The pilot died.

[sycamore]

Absolutely no idea of what the `picture` should be inverted....

Another low level barrel roll nearly goes west
Pilot killed, aircraft destroyed.
If that qualifies as "nearly goes west", I shudder to think what would qualify as having fully 'gone west' :eek:​​​​​​​

People on the ground also killed?
I'd say the maneuver itself went South ... but that's a different turn of phrase.

It looked to me like some version of an aileron roll series that didn't apply that little bit of nose up as the roll commenced...interesting bounce and go/touch and go there.

(Guessing the fatal injuries were related to the ejection (any number of ways that can to wrong) as it looked like a good chute)

Second crew member, a wg cdr survived, The pilot died of injuries later in hospital.

Another vivid example of 'HOW THE EARTH SUCKS!' Yak-130 crashing and bouncing off the runway (from 06 sec to 21 sec)

My assumption was related to landing in the water and then encountering difficulties.

Could indeed be any number of ways it went wrong but I would guess the aircraft pitch down (which probably finalised the ejection decision) would have produced significant negative g and a speed increase resulting in a very hostile ejection environment.

“The government's Inter-Services Public Relations (ISPR) said in a statement that the training jet had 'crashed due to a mechanical failure'.

It would be interesting to know the interval between impacting the runway and loss of control/ejection.

The two ejections look to be at very low level, an increasing rate of descent, one in a dive but erect, one inverted and past the vertical.

Ejection 1: nose dropping rapidly, so initiated when almost erect.

[Mogwi]

The ejections appear to have been within the dynamic limits of the seat, witness the time in the ‘chute. Negative G would have been painful (at the best!) and could well have caused incapacitation. I do not know the system but the aircraft may well have command ejection and one of the pilots may have already been incapacitated by the runway impact.

Won’t be the last time that low-level aeros kill someone, unfortunately.

Would a normal rank flight instructor dare to initiate a low level maneuver like this with a wing commander on board?

[Thud_and_Blunder]

Just read the flightglobal flight test report on the Yak 130 here (https://www.flightglobal.com/flight-test-yak-130-proves-versatility/105894.article) which states that the aircraft has K36 seats and command ejection. Yet another plaudit for an ageing but really effective ejection system. Youtoob has a very entertaining description of an incident in 1975 here where the seat proved its capabilities - well worth a quarter of an hour of your life

Are you are assuming the normal rank flight instructor was the one who flew the manoeuvre, or are you suggesting it was the wing commander who did it? Do we know which seat the handling pilot was occupying?

What is not in doubt is that aileron rolls at low level bring a risk which escalates markedly if they are in any way loaded, don't start with a pitch up, or are continued beyond the first 360deg of roll.

[dead_pan]

Horrible ejection geometry for the second person out (the pilot?).

Also, WTF was that manoeuvre??

[dead_pan]

Looks like they were on the downwind leg trying to save the a/c

Rapid pitch down because it stalled when the damaged engines quit? Strangely similar to PIA 8303, which scraped its engines down the runway then stalled in the circuit when they failed because of the damage.

Pretty sure that was not a stall. More like loss of control caused by damaged controls from the fire - hydraulic lines, control rods/cables etc.

Appears to have been an attempt at an aileron roll, or maybe a series of them, that went wrong.
I think Fortissimo put it succinctly:

[DogTailRed2]

How many pilots have bought the farm performing rolls that end up in a downward trajectory?

[megan]

Pretty sure that was not a stall. More like loss of control caused by damaged controls from the fire - hydraulic lines, control rods/cables etcEngine fire burning through the control rods lead to the death of one of our A-4 pilots when he was flying a two seat Mig 15, no bang seats, took off turned down wind, and it was all over, extremely quick event.
