The CFI was a nice young fellow that I had met at the airport so I felt good about him. It was terrible windy that morning, gusts 20 kts plus and I told him I really did not want to fly then, but he sorta insisted so off we went. He had never flown in a XL or any experimental plane before. We climbed to 3500 and it was still pretty bumpy. I was fighting the gusts pretty hard and he commented about why I could not keep the plane at a steady altitude? I offered the stick and he could not keep it steady either. I climbed on up to 4500 and offered some stalls and I think he was getting a bit green looking as the winds were even worse. After flying around about an hour I heard the radio say the winds were getting worse so I told him we probably should get on down. On down wind I had to full cross control just to fly straight. On short final just as I flared the right wing ballooned up even with full aileron trying to keep the wing down. I bumped the throttle, straightened her out and finally dropped her in, one wheel at at time. As we were taxiing I told him I owed him two more landings and he declined. I think he was ready to puke. He complemented my ability and said that it was the hairiest landing conditions he had ever flew in. I sure hope he fly's with me again when I need another CR. You'll do fine.

The is a short and a long answer. The short answer is that, in the two cases of Rotax pump failure in my plane, the electric boost pump, which is in series and precedes the Rotax pump, managed to pump through the failing Rotax pump. In both cases, there was a failure of the check valves and not a diaphram failure, which is nasty indeed, but unlikely to happen if one replaces the Rotax pump at TBO regardless of whether one overhauls the engine at that time. The long answer covers two choices, which are placing the electric boost pump parallel or in series with the mechanical Rotax pump. Both arrangements have pros and cons. Parallel placement: Either one uses one check valve in each parallel branch immediately after the electric or mechanical pump. For that choice, the specter of failing check valves looms. Or one omits such check valves and trusts that the internal check valve in the electrical pump holds while the mechanical pump is working, and that the mechanical pump will retain its internal check valve function even when it fails otherwise. In my opinion, if I went for the parallel placement choice, I would go with the choice of two check valves. Series placement: One trusts that the electric valve will not somehow become internally clogged and prevent the mechanical pump from getting fuel, and one also trusts that in case of mechanical pump failure the electric pump will still be able to pump through the mechanical pump. In our installation we opted for the series placement choice. It is the simplest arrangement, and when one argues through the two possible types of pump failures (diaphram failure versus check valve failure), then it seemed to us that series arrangement is likely to save the day in case of pump failure. But this is a matter of opinion, and everybody must make his/her own decision for this important choice.

Generally, the following holds. If the static line is disconnected in the cabine, then the airspeed indicates higher, since cabin pressure is always less than outside pressure. So there is no surprise that disconnecting the static line in your cockpit boosted airspeed indication a bit. It is easy to test integrity of the pitot line. Disconnect the line in the cockpit. Put a balloon on the pitot end of the line. In the cockpit blow into the tube, thus inflating the balloon. Seal the line in the cockpit. The balloon should stay inflated for a considerable period of time, thus indicating no major leak. If the balloon collapses quickly, then there is a major leak. If I were to guess, I would say that your installation will pass the above test. I suspect that the placement and length of the pitot tube is the culprit. This is due to influence on airflow by the leading slats of the 701. To test for this, simply extend the pitot tube so that the inlet is quite a bit forward of the leading edge. Make sure that this extension cannot cause damage to the pitot tube attachment in flight. Then fly and test if this solves the problem.
