Kestrel DG200 canopy mod.
OK
Anyone out there with experience in converting the T59D / 401 Kestrel canopy from the awful removable thing with a hoop exactly where you want to watch the tug, to a single piece. Apparently there is an approved mod using a DG200 canopy. Second question is - would there be anyone with such a canopy /frame assembly for sale. As I understand it you need the entire DG hinge and pedestal part too. FWIW - I am considering modifying a Mark 2 Slingsby T59D Kestrel 19m - though to the best of my knowledge the canopy and cockpit is identical on the various Kestrels. Any advice gladly received. Cheers Bruce |

Kestrel DG200 canopy mod.
Not too long ago there were pictures of a Kestrel 17 on Hansjorg Streifeneders web pages with a single piece forward hinged canopy modifcation ....this glider was being offered for sale but I think the ad said "Streifeneder" modification to canopy.
noted on their website: http://www.streifly.de/segelflugzeug-service-e.htm You have some fancy ideas for modifying your aircraft? Please tell us. Actually there is not much we are not able to put into practice. Some of our works we · a.. a continous long canopy for Kestrel · b.. an elongated front canopy for ASH 25 · c.. a long one-piece canopy for ASH 25 · d.. an elongated forward hinged canopy for Discus · e.. seat cushion and sidewall panels in genuine leather, seat heating · f.. and much more... try asking him, his website is http://www.streifly.de/home-e.htm tim Please visit the Wings & Wheels website at www.wingsandwheels.com "Bruce" wrote in message ...

Whilst you're waiting for the fix from Streifeneder, try different
flap settings on tow. Jim |

In England Don Austin has put a one-piece canopy on a kestrel,it looks like
a next generation ship,he dosen't know when to stop though, he also put suspension,a disc brake and wing tips.

Sounds perfectly reasonable to me. Winglets, disk brake and a single
pece cockpit - a little wing profiling and you have a very nice sailplane for a fraction of the cost of one (15m) with maybe 3% better performance... A new 18m ship would cost me five times the investment for maybe 10% more L/D. If you just want to have fun then it is a poor investment. The locally developed modification with polyhedral wingtips and winglets seems to narrow that performance gap even further. So that is a probable change when time and money allow. Mine has already had a complete cosmetic going over and wing profile - needs some work to pretty the cockpit up and then she is as good as new. Lovely glider as she is - But that canopy has to go.

Kestrel DG200 canopy mod.
But wouldn't putting winglets on the bird invalidate the Type
Certicate? I've been toying with the idea of the double-panel spoiler modification, but I've been told that my TC would be gone and I'd be in the "owner maintenance" category. I'm not sure that that's a good idea. I can understand upgrading the brakes and canopy not interfering with the TC, but wouldn't the winglets be a structural change, and thereby invalidate the TC? As an aside, my TC states that my Kestrel must be "all white", with blue-grey (or similar light) registration marks. I understand that it was written in the early days of FRP, but would it be allowable now to put bright red anti-collision accents on the extremities? |

In South Africa gliders are maintained much as the BGA did before the EASA onslaught. So we are - by definition - in owner maintenance world. No type certificates are significant, except for first registration of a type in the country. The winglets are manufactured and tested by a qualified aero engineering business. Any structural modification like this is subject to a pretty rigorous approval process, then it is up to owners to decide if they want them. As long as the change is performed and approved by a suitably qualified person and signed off in the log book there is no difference to flying a factory standard ship. Except that you can embarrass some newer glass. It does make it harder to sell to places that do rely on type certificates. |

I'm almost certain that I have seen at least one 17 meter Kestrel with an aft hinged canopy. I don't know if this was a factory (Glasflugel) canopy or an owner modification. Perhaps this could be adapted to accommodate the 19 meter canopy as well.
