Turns out it is likely due to a known 787 issue, whereby the nose gear locking pin could easily be installed in the drag race pivot link by mistake, which could lead to gear collapse during ground testing.
Oh dear…

If it’s a known issue, why aren’t people specifically trained to avoid this mistake?

Perhaps it’s lack of training, perhaps it’s human error, perhaps it’s not even been properly communicated to airlines - Boeing does have previous in this regard - however, regardless, lawyers are no doub rubbing their hands.

Damage to the Aircraft, ground handling equipment, tarmac, people, cargo.
It not going to be a cheap one to put right.
To me it seems that having something simple such as a “locking Pin” that holds the nose wheel from collapsing, is a recipe for disaster without the necessary safeguards in place, like a sensor of some degree*

So, I looking at this and thinking ok sure.
But then I was thinking, if that pin has to be in place to stop it collapsing on the ground, surely the pin would need to be in place for taxi/landing, or it would collapse on a whim.
I may be overthinking

This AD was prompted by reports that the nose landing gear (NLG) retracted on the ground, with weight on the airplane's wheels, due to the incorrect installation of a NLG downlock pin in the apex pin inner bore of the NLG lock link assembly. The FAA is issuing this AD to address the NLG downlock pin being incorrectly installed in the apex pin inner bore of the NLG lock link assembly, which could result in the NLG retracting on the ground, possibly causing serious injuries to personnel and passengers and substantial damage to the airplane.
