Hi All,
 
I have been flying my new (to me) Yak 55M for about a month now, and love it. It has been a very straightforward transition from the Su29, and frankly, surprisingly comparable in terms of performance (don't tell the Sukh drivers...).
 
I have found little to be concerned about with the airplane, but do have two very minor squawks about the airframe. First off, the bungee that retracts the canopy is "un-bunged", i.e., it is stretched out to the point where the cable hangs loosely when the canopy is fully open. I would like to replace this, and recognise that this will require pulling the seat back out, and climbing back there to try get at the bungee. However, before I begin, I was wondering if any of you with more expertise than I would know WHAT kind of bungee I need, or the particulars of it's fabrication (length, number of cords, method of attachment...) (ideally, I only want to crawl back there once...), or if any special tools are required. The maintenance books which I have are silent on this subject (or maybe that is in the Russian ones that I can't read...).
 
Second, the cable which actuates the canopy latch (and which runs in the front bow from the little knob hanging from the top of the bow down to the pin on the starboard side) is starting to fray at the pull-knob. I would like to replace it before it brakes. It looks like standard control cabling material, but I can't see the fittings (since they are inside the bow) and can't tell what would be involved in a) removal/replacement, and b) how the cable attached to the fittings. Anybody have any experience with this?
 
Thanks,
 
Scott

Scott,

I had my bungee system and the entire canopy system for that matter on my
Yak-55 "adjusted" by Cliff Coy with Gesoco last March and its 100% better
than it was. You may want to call Cliff for advise if you're going to do it
yourself.
