That's what I recall causing the dive in values. The quick fix was to
tighten the speed envelopes I thought. But that was 1999. This is now. One of our CFI-G/Tow pilots starts his Navy BPT next month. He said all T-34B's(? or civilian use?) were grounded a couple of weeks ago and there will be spar mods required. Don't know how the A differs from the B, but the Navy trainers are still flying for now. He's looking forward to flying with a turbo. He thinks his winch launching experiences have him ready for carrier ops:^) Frank "Mark James Boyd" wrote in message news:406b0c5e$1@darkstar... I'd recommend reading about the asymmetric loading arguments presented at: http://www.avweb.com/news/columns/182086-1.html The meat of the matter starts about halfway down the page. Essentially it says full aileron and full elevator when applied simultaneously create a much greater chance of wing failure at a lower airspeed than just applying either one independently. I'm not aware of how this may or may not apply to gliders. Perhaps some expert in wing construction can give most welcome educated opinion... F.L.

A lot has been written here about G loads. I recall that the T-34 (an aerobatic power plane I have a little time in which is sortof a tandem Beech 33) had some issues with wings coming off during aerobatics. The recorded G loads and mauevers indicated the aircraft wasn't flown outside of G limits. How did the wings separate? Some smarty folks said it was because the twisting G load that the wing could endure was much less than the static tested load. If the ailerons were deflected and the thing was in a steep spiral (as opposed to straight dive) there were twisting loads. Thought I heard that inspections showed T-34 wings were suffering from fatigue cracks. Kind of shot down some of the 'fighter dude' thrill rides (we have/had one in Colorado). We have a disassembled T-34 wrapped in plastic in our hangar. I recall a conversation about the value dropping by about 50% when the crack problem was discovered. -- ------------+ Mark Boyd Avenal, California, USA |
