Strange taxing accident. 737 separates from tug... fatal injury to tug driver

Fri Feb 07, 2020 10:36 pm

I searched and did not see this bizarre accident which occurred at Don Meuang Airport. Evidently a 737 under tow separated from the tug then moving forward and running the tug over. How does this happen??

They probably hit the brakes too hard and at an angle which sheared the towbar and caused the nose gear to veer. They were not moving when the plane ran them over. For the operators, it probably happened so fast they had no time to react.

Nothing protects the tug operator of those small tugs from the airplane. The low stance of the 737 did not help in this case.

They didn't hit the brakes to hard they were using a TUG which isn't the correct piece of equipment when towing a 737.

Here in the States we use TUG's to tow baggage carts and freight, on some occasions I have seen a TUG used to move an empty 50 seater RJ at the hangar but never on a 737 on a active taxiway. I could be wrong but I don't think that piece of equipment was designed to tow 737s.

This is just a standard push back tug (a smaller one, for the smaller jets), as used everywhere in the world. The driving cabins are light build, as they can ascend so the driver has a better view. As the cabins are so light build, the driver is only weak protected, when the jet drives over the flat pushback tug and crashes the cabin. Sad to see this accident.

This is why I hate the seatbelt requirement for pushing back. I want to be able to quickly bail if something like this happens. Not sure it would’ve mattered in this case but it reinforces my concern about being strapped in.

Doesn’t look like one we use in states but the video is very bad.

Yeah, from the video it looks like the tow bar breaks at the six second mark and he's likely severely injured/dead by the ten second mark. Pretty quick.

Not sure what the debate is here, I can drive across the field and see 4 different operators using 4 different pushbacks on 737. There's no standard American used style. And if you really want to push it, TUG is a specific brand.

The article does suffer from the usual aviation reporting, runway vs taxiway, etc.

Big question is where was the brake rider?

Almost looks like there's nobody riding the brakes.

The brake rider likely won't know there has been a disconnect unless the tug driver communicates it. My operation damaged two a/c in a year this way. You can't stand on the brakes for every bump and clunk while under tow. In fact an errant brake application can break the shear pin, causing this very scenario to play out. It's a Catch 22.

From the video the TUG looks like it could be a Toyota see the link below.

While UA is moving towards more electric vehicles we still have plenty of Toyota TUG's. Again from the video it looks like this could have been the type of TUG they were using.

It's not the toyota diesel tug you are thinking of jay.

Having been a ramper, this is an unfortunate incident, but easily understandable. At some point, the shear pin broke, separating the towbar and resulting in an uncontrolled situation. Likely the brake rider knew there was an issue, unless the tug driver communicated. Tragic.

I once was pushing back an E-170 and the shear pin broke (was frequent) and realized the aircraft was freely rolling backward toward a 20-30' ravine. Just communicated "Brake brake BRAKE" and they applied the brakes. It was moving away from me, not towards me, low speed.

The video gives the impression that the plane seems to accelerate ( and turns around the portside MLG?)?

Did they have engines running?

I know it is too early to speculate, but watching the video it seems the Towing speed was high followed by a sudden braking by the Tug causing tow bar failure. Will have to wait for the official report to be out.
