Hmm. Flight was due to be operated by an Airbus A306 or A310, per the airline's website, and the various pictures being shared online don't seem to match up with B743.

Any other input here?

You gotta be kidding me!

Sure, just straighten some bent aluminum and return to service.

An aircraft demolished into a million pieces the FAA classifies the damage as "substantial", so yes, "minor".

Were I to venture a guess, this was a CF6 with a departed LPT rotor disc. It functions very well as a rotary saw, as evidenced in the vertical slice up into the pylon.

Scrap metal dealers along the flight path will show a profit this month.

Damage to engines is usually not included into the classification. Slap on a new engine and this plane looks good to go...

The NTSB in 49 CFR 830.2 defines substantial damage and specifically says engine failure or damage limited to one engine is not substantial. It looks like the engine disassembled itself and tried to leave out the back end. Not an uncontained failure. There is one interesting tear/cut in the bottom of the pylon in the top aircraft photo.

I was thinking the same thing - the CF6-50 is becoming somewhat notorious for loosing turbine discs.
I've been at a couple CF6 operator conferences where GE hammered on the need to do the inspections, etc. to prevent turbine disc failures. The problem is the operators that are bursting turbine discs are not the ones that bother to go to operator conferences (or apparently pay much attention to the associated ADs ).

Surely the problem in Iran is the trade embargo.
They can't get the bits. Or buy newer aircraft.
They have developed an amazing make do and mend culture that kept the F-14s in the air. But that has obvious limits.

GE would have specific time specific operating limitations for that engine. Wonder if they were in compliance?

Absolutely; all engine mfgrs. publish life cycle limits for rotary parts and other highly stressed parts like pressure vessels. Required by FAA, CAA, etc.

Of course, no such operators ever fly (even cargo) into certain airports where the routine approach is directly over the city centre. An engine could never depart from an aircraft over a major Western city. Inconceivable.

I think OldLurker is ironic on his statement.
