787 genuflecting nose gear issue

[Quickstatus]

There has now been 3 inadvertent B787 nose gear retractions while on the ground.
KE 2018
BA 2021
LH 2026

The root cause for the first 2 are known. The manually inserted lock pin to prevent inadvertent nose gear retraction was incorrectly inserted into an adjacent similar looking hole. . The fix - to permanently block off that adjacent hole was promulgated by Boeing in 2018 after the first nosegear incident. The BA nose gear incident reported in the above AAIB report link occurred in 2021. BA did not do the fix because it was within the 36months grace period to effect the fix.

I would have thought that as because the LH aircraft was only a few months old that the fix would have been done on the manufacturing line. Assuming that is true and it is now impossible to inserts the lock pin incorrectly, possibly something else caused the inadvertent nosegear retraction??

Assuming the pin was there at all.

I guess we'll find out in due course...

Once the cause has been pin-pointed

Yep, the "something else" includes forgetting to insert the lock pin or raising the gear without first checking the pin is in.

Human error cannot be completely reduced to zero.

Good grief… Loyalty Lobby reported that the LH 787 had ‘plunged’ to the ground, and the repairs would be very costly if in fact repairs could be done at all!

LL strongly suggests the plane will need to be ‘written off’ as a result of this. Backed up further by saying they’d hate to be the airport worker responsible writing off a $300m plane.

Still, a lesson for media students in click-bait hyperbole.

Wouldn't expect anything less from LL

as I have learned and confirmed on many occasions, you can make most things fool-proof, but you can't make anything idiot-proof.
