Lots To Do

Maintenance doesn't do itself! The club depends on you, the members, to show up and work on our fleet of aircraft on Saturday mornings. After each season of flying, the gliders and tow planes need many hours of work to keep them in good flying condition. Each winter we tackle that work.
Those of you who've never come out and worked with the maintenance crew: Don't be intimidated. Helping with the work is a great way to learn about the mechanical operation of the gliders and the systems associated with them.
The maintenance crew really appreciate the dedicated group that shows up in the (sometimes) cold weather to help. We all benefit when we can keep our maintenance costs down by doing the bulk of the work ourselves.
Promoting education in equipment care is one of the purposes of CISS:

This Corporation exists for the purpose of (a) promoting the science of motorless flight; (b) finance educational programs to inform the general public of the science of motorless flight; (c) sponsoring and promoting education in flying safety and equipment care; and (d) providing facilities and equipment to test motorless aircraft for the public safety.

And most of the serious, down-and-dirty maintenance and repair work gets done in the cold of winter - just as most of the serious flying gets done in the sunny days of spring and summer.
