removing mylars at every annual?

How are I.A.s dealing with inspecting around mylars, are they removing these spendy items every year. If not, what are the control surface hinge inspection considerations?

this came up recently for me, luckily I had tissu tape on the upper gap, not so spendy, but before I put on mylars id like to be better informd.

Thanks,
Scott

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)..

Uh no. ...but that does reminds me of a great story, I'll not mention the location to save embarrassment,... a new line boy is being showed the ropes, how to remove wing tape on a glider at the end of a day. He is asked to finish that off and the supervisor leaves... to come back later and find all the mylars removed as well.
