				Aircraft jacks don't fail me now!
			 
			Every time I jack an airplane to do a landing gear function test, I just can't get over how wrong it looks.   Here are a few pics with the owner standing in the cockpit after he raised the gear while I watched from the ground. Maybe you have to be there, but it just wierds me out knowing that 250K of airplane is precariously resting on my jacks. Airplane shown is a Beech T-34 Mentor trainer from the 50's.

			Beautiful airplane, beautiful work, Tim. I have about 250 hours in the T-34C, the little turbo model with the jet engine driving the propr. Man, would I love to own one of those....

			I love watching the functional tests out in final assembly here in the Boeing Everett plant.  Fascinating to watch a 747, 767, or 777 with the gear going up and down, flaps and spoilers deploying, control surface wagging up and down or back and fort, and all of that.  Yes, it is a little unsettling seeing one up on jack stands.

			New Torsion bars, Koni Shocks and some Sway bars should help with the Landings. Nice Plane man.

			That 520 must sound pretty beefy with the augmenter tube exhaust. I have some time in a B model with the original 470 and it sounded awesome.  I think I remember the 470 had a pressure carburetor. Does the 520 STC involve a lot of modification due to the fuel injection? I have helped do a gear swing on a Brasilia and that was definately freaky having such a large airplane jacked up. The mechanic forgot to pull the WOW circuit breakers so as soon as it powered up pretty much every aural warning went off.

			All went well, no leaks and it fired after just a couple revolutions!  It is gone!  Unfortunately, it was replaced by a club 172 partially owned by one of the T34's owners.  I need to just start saying no. The RC hanging from the ceiling is a 33% scale Giles. While I have quite a collection of flying RC planes, that particular one is stripped of it's 4 cylinder DA 15 hp engine and the 9 high torque servoes and twin receivers. A friend of mine traded it to me for some work I did on his Navion. I doubt that I will ever take the time (or blow the cash for the $2500 worth of engine and servoes) to get it flying again, but it sure looks pretty cool as a hangar decoration now. The 520 does sound loud as it just has straight 6 into 2 exhaust stacks dumping into those big tubes. I don't believe the conversion to the 520 is too difficult allthough the sheet metal up front appears to have required some mods. I know it is impossible to remove the cylinders without removing the engine though, which is not the case with most small airplanes. It has always had this engine since I started working on this plane three years ago. I am not sure about how the old military markings are treated, but many old warbirds which are now certified as civilian owned, have military markings, so it is pretty common.

			Tim, I am like you, always worry when I put a bird up on jacks. We were doing "free fall" tests on an old Beech 18 years ago and the guy in charge got too wild with his dropping the gear and it punched a hole in the wing, so its worth being careful. Have flown one of the 520 conversions and its nice. Not any faster but the climb rate is better, especially in high density altitude situations. Joe

 ...Saw a doofus try to use King Air jacks to support a Debonaire that had geared-up...same result when they tried to pop 'em...Was sad, it was 2 CFI's at a local college, flying at night with their dates. Guess not seeing "3 green" was not not too important that night. "Oh, I thought you....." They needed 3 down and welded that evening.

 The speed and G load restriction is a bummer for these guys, but they mainly just use it to participate in warbird shows (they enjoy the formation work). The value of these birds have taken a huge hit due to the wing failures of a couple of high time birds being overworked and overstressed in those psuedo dogfighting schools.
