... "BT" wrote in message ... Is it an accident that you did not do as instructed? Or is it negligence. The two are not mutually exclusive, so your answer is "both". We are all capable of doing dumb things. (though some of us may be more capable than others) Vaughn True, although the point that has been missed in this discussion, on at least two newsgroups, is the maintenance issue--especially with respect to the breaker points in the magnetos. When the breaker points, a/k/a e-gap, are not correctly set, there will usually be insufficient spark to easily start the engine be hand propping. When that problem occurs, it is discuoragingly common to experiment a little in an effort to get the engine started. Also, most people are unaware of how much thrust the engine can develop--the old rule of thumb is about one fifth of the certificated gross weight of the aircraft and most production aircraft with fixed pitch props come very close to that number. That means many of the tie down ropes and anchors, especially the temporary varieties, are little more trustworthy than chocks for the purpose. I have heard a couple of very amusing old stories in which the aircarft supposedly flew after "getting loose" when hand propped. In both of the most entertaining cases, the aircraft eventually landed safety. In one case, the pilot hand propped an Ercoupe and the pilots wife, who was a frequent passenger but not a pilot, was in the aircraft and "stepped up" as a pinch hitter--successfully landing rather firmly but without damage after a couple of missed approaches. In the other case, the pilot's young son, aged around 6 years, was in the aircraft and sinply waited untill the aircraft landed itself due to fuel exhaustion--although I personally susspect that the kid may have also "stepped up" and influenced the landing site to favaor an especially flat and open area. In both cases, the throttles had supposedly been advanced to facilitate a difficult start, and the engines supposedly commenced to operate at about 1800 RPM. Therefore, IMHO, proper maintenance of magnetos would be at least as effective a solution as any other! Peter A SAFE, HEALTHY, AND PROSPEROUS NEW YEAR TO ALL !!!! |
