How do you accidently retract the landing gear?!

I thought that aircraft had some sort of pressure sensor on the landing gear so that when on the ground, even if the gear lever is accidentally activated, the gear remains in the down and locked postion.

all aircraft,have a safty mechanism,its called weight on wheels,but they can be over riden,for some tests,but airbus,have a nose gear that is angled slightly forward,and can cause u/c collapse,when gear selected up.
this is not the first time this as happened on these aircraft.

There may be a problem with Airbus but in this case it's a Boeing 737 :think:

Oh dear ! Could be a Chinese Engineer signing on at the Beijing Job Club this morning.

It could be that maintenance on the hydraulics resulted in an undercarriage cycle at the end - the idea as Garry points out is to insert the gear pins to physically prevent the gear retracting. Maybe that didn't happen on this occasion - or the pin sheared. Either way there's a bit of panel beating to do :redface:

Wow...the 737-9000 sure came out and into service quickly....

It's a 767-300 that is shown in the mishap. But the likely issue is the same that it's been every other time - idiot mechanic. Override the gear retract safeties select the gear up without putting the pins in, nose gear folds forward as it's supposed to because there is no brakes nor substantial friction to keep it from doing so unlike with the mains which retract inwards.
