Hi All, Fairly early in my gliding career my winch launching club bought an IS 29.
I was so concerned by what I considered its unsafe winch launching characteristics that I bought a Pilatus B4 for the use of my son who was very early solo. The IS 29 has a very narrow speed range on a winch, bites very quickly and unexpectantly, and the flap detente on the one we flew had a nasty habit of jumping out and going into negative. Sometime after I stopped flying it there was an accident involving power failure or cable break with a pilot of modest experience. There has been one pilot killed in Australia winch launching an IS 29 and I understand their accident record has been high. The one good thing is that metal gliders crumple giving a higher degree of impact absorbtion than fibreglass which shatters. I am a great believer in all pilots flying safer gliders. We do not all have the same skill levels and everyone's abilities deteriorate under stress. We have to look after those of us at the lower level of acceptable skill levels. Who of us can say we have never been caught out momentarily by an unexpected situation? Low level stall-spin accidents and resulting fatalities have greatly reduced in Europe over a period of years. Credit for this has been given to the much safer characteristics of modern gliders rather than any change in pilots skill levels. My personal belief is that the importation of gliders with a poor safety record, such as the Puchaz with its history of spin related crashes should be discouraged or banned by the GFA. Wait a minute before replying until I don my flame resistant suit!
