787 Nose Gear Collapses - That'll buff out, right?
- Thread starter PWMDMD
- Start date
If I am grounds crew, I am not going near those planes without a custom "large steel I-beam trailer" rolled under the plane, 3 ft behind the nose landing gear. And I am not taking the opinion of the manufacture............ "OK guys, we fixed it".
Did the Boeing aircraft make a "boinnng" sound when it collapsed?
I'll see myself out now.

proof that bad things happen when you stick pins in the wrong holes
I understand the purpose of the pin but in this case does that mean someone accidentally retracted the gear or did it collapse for other reasons? Sorry, I don't know much about plane landing gear.
There are technical/troubleshooting reasons to put the gear handle up with the airplane on the ground.
During those operations, the landing gear is "pinned" so that the landing gear actuators cannot move, even with hydraulic pressure applied.
But if the gear is not pinned correctly, then, well, it can move under hydraulic pressure - and this is the result.
Thank you, makes sense.
I don't know much about flying or planes but I've always loved watching them and I'm really into watching TikToks about flying and communications with ATC.
One would think that it would be reasonably simple to make it very idiot proof. Square peg, square hole, uniquely sized, color coded, "safety pin goes here" engravings, etc. Maybe even a sensor. Heck, even my lawn mower shuts itself off if I remove my backside from the seat.

Here is a test gone wrong:
Boeing released a service bulletin after this happened once or twice before, and FAA issued an AD giving 36 mos to comply.
The SB involves plugging the hole that the gear safety pin can wrongly get inserted into.
Glad nobody got hurt or killed in this one. Super scary to think of the consequences if someone had been under it.

Human Factors
I wonder now how many of these SB's are going to be fast tracked? Like really how hard is it to insert and torque a bolt & nut that prevents this from happening? Would the plane have to be pulled from service to do this?
The bolt and nut would not have done any good.
Gear pins, as a concept are good - a steel pin inserted in the linkage to prevent its movement.
A bolt and nut are difficult to remove, which compromises the safety of the flight - because they would prevent the gear from retracting and cause an overweight landing.
The problem here was not the pin, it was the insertion of the pin in the wrong location. A bolt inserted in the wrong location would be equally ineffective.
There’s no need to replace the pin.
There is a need to train crews where to put that thing.
