I wonder what tasks the engineer was undertaking while he was onboard.

I was supposed to be on that plane - SQ890 to HK. After a gate change and late departure the captain apologised for late departure due to "engineering difficulties"

Injuries

I'm glad no one was killed or injured. (Other than pride)

Few bucks worth of damage there, cabin door looks like it's been torn out as well.

Is it resting on the nacelles or are they still clear of the ground?

I would have thought the Airbus System Logic would prevent gear retraction on the ground? I'm not suggesting the gear lever was selected up, but thought there'd be a general logic to prevent gear retract on the ground?

Can't see a ground engineer between the ladder and the plane...must have been in stores looking for that matching replacement part.

most a/c have a squat switch that will prevent gear retraction on the ground. It can be overridden during mx ( the article stated "undergoing a landing gear system check"?). A few people have lost their job after an aircraft was found kneeling (the main gear is usually different). Can also be mechanical failure, but I haven't heard of that happening on A330 yet

The photos I took show it on the nacelles - but only just

Not totally up to speed on 330 quirks, but 2 airlines I am aware of supply nose gear downlock pins attached to steering bypass pins to their 330 line mx providers.
There's probably a reason?

This thread

http://www.pprune.org/tech-log/22901...-pushback.html

suggests that a few A330 operators use a belt-and-braces approach where the NLG downlock pin is used on pushback, as well as its normal use for towing and landing gear maintenance, in which case I suppose it makes sense to keep the gear pin and steering lockout pin together.

You mean people push back/pull forwards without a nose pin in place?/ REALLY

I seem to recall the Trident had an offset, sideways retracting NG. That had a structural advantage, and would be less likely to see accidental retraction IMHO.

Yes and no, respectively.

It does. There are several near/far prox sensors dotted about. To get the gear to move on the ground the prox sensors need to be 'gagged' with metal slivers to simulate a 'near' target position. The computer logic will then let you raise the gear lever on ground. Assuming the gear pins are fitted the doors will open the gear will shudder a bit when the 'up' line pressurises and we all breath again.

The rumour network has suggested that the eng was replacing a landing gear lever module. An unconfirmed rumour suggests that the crew came along, saw the nose gear pin in place and removed it prior to the function test. Personally I find that hard to believe but it will stir the pot until we know more.

Glad no one was hurt. Could have been nasty.
