PIA jet makes emergency landing
ISLAMABAD, July 9: A Pakistan International Airlines (PIA) aircraft carrying 433 passengers made an emergency landing at Jeddah airport on Monday because of fire alarm, officials said.
The flight, PK-742, manned by 15 crew members, was coming to Islamabad when it developed a technical fault shortly after take-off.
Engineers said that the turbine of one of the engines disintegrated during the aircraft's ascent, adding that it happened before the aircraft was hardly over 1,000 feet high. This caused a fire warning and the 'bottles operated'.
"It was a rare incident," an engineer said.
No one was injured in the incident, which caused panic among hundreds of passengers and the airport authorities, a source in the airline said.
All 16 tyres of the aircraft deflated on landing.
I wonder how many more of these "rare incidents" will be happening with PIA until they get there ducks in a row. How hard is it to maintain your planes in a condition where you won't have a incident every few months? Someone in the PIA management needs to take steps to curb this loot which is taking place in the PIA maintenance section. I was planning a KHI-ISB run this august on one of their 747-300 but if incidents like this continue to happen my business will probably go to air blue.

Quoting Highpeaklad (Reply 8): Jeddah to Islamabad can't be all that far for a 747 so I wouldn't think they'd have a full load.
JED is the stopping point for most pakistani muslim pilgrims when going to perform umrah (mini-haj). This could have easily meant a lot of cargo due to the various gifts people buy for their friends and family (433 passengers with all their baggage adds up). Surely if the 747 was lightly loaded, its' tires shouldn't have burst upon landing. just a thought

Well that's a normal incident & thank god every thing ended safe. Don't blame maintenance now, may be a bird strike happened during the T/O.

Quoting Imiakhtar (Reply 1): I'm no expert but shouldn't the pilots have dumped some fuel after T/O to make the 747 light enough to land without bursting all its' tires
Actually, I am going to stick my neck out and support what PIA has done.
The article said the engine "disintegrated", to me that means damaged, what else it has damaged in the process would be unknown (may have ruptured fuel tanks, hydraulics, leading/trailing edge flaps, one or two less thrust reverses etc). How damaged, dont know when your a pilot, its the maintenance people who can tell you that sort of information when you on the ground, all you have in the cockpit in regard to the engine health is the engine RPM (N1/N2/N3 EPR etc), oil pressure/temp/level, vibration levels, and the fire loop status. If the engine "disintegrated" cutting the fire loops in the process it can show up as a fire in the cockpit, and even after putting two loads of agents into the engine it could still indicate a fire, it may or may not be a false positive.
So you are in one of the worst scenarios possible, indication of an uncontrolled engine fire at high gross weight after takeoff, your primary priority then is to get the aircraft back on the ground asap, get the pax safe, and let the fire trucks on the ground put the fire out.
Quoting Legoguy (Reply 2): The 747 has more tyres than that!?! Perhaps all wheels of the main undercarriage burst.
Only the 16 main have brakes on them, the nose wheels do not have brakes, I would think the thermal plugs in the tyre rims would have melted causing them to deflate.
