|What lurks beneath the pilot's seat in a Grob 103|
I was happy to get a look at how sailplanes are put together. It was comforting to see that the flight control linkages are composed of very stout and reliable pushrods. Now I know that capacity flasks really exist--I counted three of them in the Grob--and are not just figments of the Glider Flying Handbook's imagination. Though I know nothing about aeronautical engineering, I found the overall design of the ASK-21 to be extremely well thought out. For example, the holes in the seat pan allow the safety belt buckles to just barely fit through, making disassembly easier than it otherwise would have been.
These gliders are simple compared to powered airplanes, and simple is a virtue: the actual inspection process took only a few hours. After a tailwheel tire replacement on one and an air brake adjustment on the other, both gliders were back in service and flying this afternoon.
My tiny contribution to the project was unskilled labor. Aside from asking lots of questions and just generally pitching in, I removed the petrified residue of old gap seal tape from the control surfaces and wing roots with liberal application of Goo Gone and elbow grease. I was told that this tape actually reduces the stall speed of the glider by 2-3 knots.
