A Sepahan Air Iran-140 plane bound for Tabas in northeast Iran has crashed in a residential area after taking off from Tehran's Mehrabad airport, killing all 48 passengers and crew, Iranian state media reported.

The plane that crashed - an Iran-140 - is a locally assembled version of the Antonov-140

These tragesdies in Iranian aviation are a real unfortunate consequence of international sanctions against Iran

Oh, so that's that incident investigation sorted so.

The consequences of Iran developing a nuclear arms programme would be a lot more 'unfortunate' for everyone else.

So because these are "only" Iranian men, women and children, and not westerners, the only comments this thread gets are moronic political waffle.

What about actually discussing the incident, like is done for even minor incidents in the west. Again, like in so many incidents, I notice this plane took off with around an 8 knot tailwind. Hot and high; 36 °C at 4,000 ft altitude (so a 7,300 ft density altitude). R29L is 13,249 ft long, but I wonder if the extra ground roll due to the tailwind plus high density altitude cost them valuable altitude when one engine quit, as has been stated by the airline. Taking off in the other direction would have meant being a few hundred feet higher at that point. Maybe still not enough to make a turn back but still more time to make a better landing with more options.

lets try and keep this discussion focused on the unfortunate aircraft accident and the tragic loss of lives. Politics can turn left and head to the Politics forum

As it was built new in 2008 in Iran, international sanctions can hardly be blamed.

Losing an engine on take off wouldn't normally cause a crash on modern aircraft but apparently it hit wires which ripped off the tail just before crashing. When you add that to this from FWVT:

Even with all that they might well have been able to turn back if the wires hadn't intervened.

I doubt if we'll ever heard the full truth of the accident it being Iran after all.

What do you mean by "turn back"? I wold expect an aircraft certified to -25 standards to be able to climb out on one engine, rather than just a turn back, unfortunately i have no idea about Russian design standards.

?? Turn back, shorthand for: Return to the airport after carrying out the appropriate emergency procedures. What else would I mean?

smurfjed

Well you could mean a 180 degree turn onto downwind ! Or an attempt to do a 180 degree turn to land on the departure runway...

Neither of which are sensible.....
