I fly regional RPT in a twin turbo prop and often, to fit in with noise abatement, ATC flow etc we land on a runway with a tailwind up to 10 knots (greater than 10 knots they change the runway). In addition, whilst it may be at or below 10 knots tailwind on the ground, even 100 feet above the runway the wind can be stronger, so more tailwind ! The effect of a gust is very noticeable as it is now performance reducing, ie your indicated airspeed will drop with a gust of wind from the rear. So your lift drops proportionaly and without recovery action you sure sink quick ! But if you've turned back due to an engine failure your 'recovery' options would be limited to whatever performance margin / energy you have left over the stall speed in your current configeration. I hate downwind landings ! They just don't feel right, and I'm talking about final approach speeds of around 100 to 120 knots so a 10 knot gust is a relatively small proportion that you can handle, though sometimes the landing is more an 'arrival', if you know what I mean ;-) In a kolb with much less 'energy' reserves it could be a quite different matter. Nb. I'm talking theoreticaly here as I have not yet got any experience in anything as light as the Kolb. But, nevertheless, a turn back decision, a decision which has to me made fairly quickly, might not be the best decision even given the positive repies of earlier posts. Safe flying all. David.

It's been noted here by others how vulnerable the fuel system is with a primer bulb in the main fuel line. The solution, one of many, I'm sure, is well documented, just put a bypass line around the bulb so fuel will flow if the check valves jam up and pinch this line off when the primer bulb is needed. The only problem I've found with this is that Bing blue fuel line is stout stuff. My solution to my weak fingers is to put in an inline valve (CPS part no. 7215) into the bypass line and a nylon tie to lock the valve in the open position for flight (I had one vibrate closed on my Kasperwing). Less than $20 for the valve, tees, and clamps. Congrats on getting back into the air and finding the problem, too.
