Air India B777 gear collapse Mumbai
I was on ground this afternoon approx 3pm in Mumbai and saw an Air India
B777 with nose gear collapsed with both engines touched down on Stand 46. Anyone knows the reason or story behind it? Are these leased United aircrafts?

Indian Airlines [sic] plane nose gear collapses
16 May, 2008, 2332 hrs IST, PTI
MUMBAI: Four engineers escaped unhurt when the nose wheel gear of an Air India Boeing 777 bound for Dubai collapsed on Friday shortly before passengers could board in the second incident at the airport involving the airline in as many days.
Yesterday, the door of an Airbus A-320 readying for take-off was damaged after an aerobridge slammed against the aircraft when the push back vehicle to tow the airplane suddenly moved. The Chennai-bound flight was delayed for more than four hours.
No one was injured in today's freak mishap as there were no passengers or cabin crew on board the Boeing 777-200 (Extended Range) aircraft leased by Air India, an airline spokesperson said in New Delhi.
The incident occured during pre-inspection checks by four engineers but they escaped unhurt. One of the engineers was in the cockpit while three others were on the ground.

Landing Gear - Down & Locked? - NO!
OUCH - 
They were never told to leave the gear lever in the down position until after rotation with the pilots in the cockpit.????
A very expensive fiddle?
Stirred?

Guess it wasn't during pushback BT 'cos the catering trucks still by R2. And the cargo doors are open.....
Engineers fiddling I'd imagine - I mean four of them all together up by the nosewheel

I don't know the 777, But on lots of A/C some maintenance procedures require Ldg Gear Lever to be placed in the UP position with Pins installed.
Saw a Northwest 747 at Gatwick many years ago with nose gear collapsed due to the Nose gear Pin shearing. I think the pin was not genuine Boeing part.
So maybe Mechs not fiddling!

VT-AIK ex N205UA owned and leased out of Emirates. The NW nose gear incident occurred because a push back pin (without spring loaded pip pin) rather than a nose gear down lock pin (with a spring loaded pip pin) was installed while the gear handle was cycled for an uplock leak check;it vibrated out on the fifth cycle.

This is not the first time and won't be the last gear is retracted on the ground.
Some simple rules can reduce the above.
1. Fit correct downlock pins.
2. Make sure downlock pin locking device is servicable and used.
You could also action Duplicate inspections and record such before gear selections are made.
All the above will have extra cost as the norm, so the bean counters will not be happy.

This accident has all the hallmarks of a test of the Alternate lowering system being carried out....a test we as engineers do quite often. Looks like they either forgot to install pin,(as happened to the BA 747 some years back),or it was a "dodgy pin" fitted.....either way it it's an expensive mistake!!

missing pins
can remember 3 cases when that happened (B747-400):
CAL at TPE; brand new freighter,
CV somewhere in China
and LH in FRA.
Heared from a mechanic that some hydraulic test procedure requires the lever to be placed up but the pins have to be installed before.
Well, weight of the plane is sufficient to hold the main gear in place but the nose gear will retract

maybe same (wrong) procedure?
