More T-34 info,
I believe there was one T-34 a couple of years back that broke up in flight due to the spar issue. We have 3 T-34's that are maintained at my shop, 2 "A's" and a "B" model. One has been away for a month or so getting the spar replaced. One is on jacks in the hangar today getting an Eddy Current Inspection on the spar and bath tub fittings. It's scheduled to have the spar replaced later this year, but requires this inspection in order to continue flying in a restricted configuration. The third one has already been replaced. There is only one place in this country that does this modification, so the waiting list runs about a year behind
.
The Bonanza's also suffer from spar problems, but not so drastic as to require spar replacement. Your are allowed to have some cracks in the spar, as long as they stay below a certain dimension, and are not located in specific areas. Beechcraft makes a reinforcement kit that fixes the problem. It only takes 40+ hours per side to install
. At $69/hr shop rate, the bill gets expensive really quick.
Enough of that though. I think there is another forum somewhere for shop talk...sorry. As my wife would say..."At least you don't have to live with it". Apparently I have a tendency to work aviation maintenance in to many conversations
