Trestles and hangar packing

Post by BarryL » Mon Sep 02, 2024 6:54 pm

Please do not wedge trestles tightly under wings in the hangar; they can cause dents in the wings. Especially so with the wooden trestles that only have a thin layer of carpet to spread the load. The two new, yellow metal wing stands are much better padded, better to use them whenever possible.

Ideally, leave a small gap between the trestle and the wing so that there is no pressure on the wing skin, but the trestle will catch the wing if it tips.

Thanks,
Barry

This one is very tight under JAD's wing.

Trestle damage on JAD's other wing, not very recent but since the refinish.

Having not DI'd JAD for a while (and not read this) this was fresh damage to my eyes so I recorded it in the DI book yesterday.

And we are still doing it!

I extracted yet another trestle from under the wing of A34 yesterday which had been quite firmly wedged!

Please take heed - these are your aircraft!

More instances of bad hangar packing and potential damage spotted;

Morning of Sunday 27th April,

The trailing edge of JAD's wing was resting on the wing of the Astir.

The wing tip was clear of the floor so a little movement by JAD could easily have damaged its trailing edge.
It looks like the tip was intended to be supported on the chair, but it had moved off it for some reason, possibly during a bit of later shuffling. Unintentional of course, but it shows we are still not being careful enough at the end of the day.

And, after packing on the Sunday;

This wooden trestle was jammed hard under the Alliance's wing, quite close to the root. If the glider moves at all, or the tyre deflates overnight, you can guarantee a crease in the wing.

This is not to try to point the finger at individuals, we all make mistakes and need to watch out for each other. This is collective carelessness, which will eventually result in damage causing expense and an aircraft lost to a repair shop. Let's all please keep an eye out in the hangar and question anything that does not look right.

Thanks!
