The integrity of the hinge can be verified by gently pushing up/down and fore/aft at each hinge post. Lubrication can be done by sticking spray-lube tube under the Mylar at each hinge.

I do the same except use a small hypodermic needle to put a small drop of oil in the hinge. Less messy than spray lube for most people.

yes, hypodermic needle is the way to go! A&Ps who use spray grease on gliders noeed to....not do that.

My AME uses Tri Flow Superior spray lube which happens to be specified for

certain helicopter rotors.

No grease = no dirt.

You can find it at bicycle shops.

LPS1 is commonly used in Colorado. Grit doesn't stick and it works well at high altitudes (white lithium grease tends to freeze up). The SZD-55 ailerons can be removed without removing external mylars at the annual for lube (requires a logbook entry and second signature by pilot confirming PCC done)..

If you have proper sealing, teflon tape under mylar, it is not possible to lubricate hinges. Use upper mylar to prevent water or dust entering hinge. Change everything after 3-5 years and lubricate using grease, not anything that comes out of spray can as it is only cosmetics.

Sure you can, if you want to, you stick a large hypodermic needle thought the teflon barrier tape and apply oil from a syringe.

Tom when you eventually make it out to CA I can demonstrate how to apply an oil injection. You'll hardly feel it.

Hole in airtight seal, interesting.

Oh no, a few hypodermic needle holes. Maybe the massive bleeding of air though those tiny holes will affect the handling, and the gliders will fall out the sky.... it's amazing whole fleets of gliders maintained in this way have not fallen out of the sky, or had any other apparent problems...
