Pietenpol-List: Hand Propping

Graham (and others),I read in the recent Luscombe Assoc. newsletter a checklist for flying aLuscombe. One of the things that caught my eye was the idea of opening thefuel and pulling through with the mags off - followed by turning the fueloff and mags on for the start. The fuel was turned on again as soon as theengine started.I assume that this would apply to any hand propped plane. Have you everheard of turning the fuel off for the startup? Is this in case the enginesomehow starts with high revolutions? Seems like a good idea. What do you think?Ted Brousseau/APFnfn00979(at)gator.naples.netSunny SW Florida________________________________________________________________________________

Ted,Back in the 1960's a friend of mine had his Stinson run away and hit a Seabee. It was a messy business from both the damage caused and the legalhassle that resulted. The Stinson's battery was dead, so he hand-proppedit and the throttle was opened a bit too much. 'Nuff said.He developed the technique you descibed and always said that had the fuelbeen shut off he would have been able to keep his plane from hitting theSeabee because it would have run out of gas first.Graham________________________________________________________________________________

I had told of a similar story to this one that happenedin 1978 on this list about two months ago. The airplane in that case made one big circle around the airport and crashed yards from where it started.The one from this last weekend was, sure enough, the same type...a Champ. I think the Champ, having the pilot sit right on the cg, has little change in trim when nobody is in it, so it flies quite nicely all by itself. People never learn...john________________________________________________________________________________

I was listening to the news this morning on the way to work, when Iheard an argument against hand propping by oneself and not restrainingthe plane.Now you're getting ahead of me. Seems a man hand propped his "vintage aircraft" this week and took offfor a two hour flight. Down side is, he wasn't able to get on boardbefore the take off. The report said the plane flew, on its own, untilit apparently ran out of gas, crashed and no one was [physically] hurt.Having one's plane crash has got to hurt.Anyway, I was wondering what type of "vintage aircraft" it was. Anyoneknow, or know any more details?ThanksBill________________________________________________________________________________

Bill, John, Yes, that was a 46' Champ that got away here in Ohio. Engine stoppedon a taxiway and he got out to restart it and away she flew.Flew 90 miles to Urbana, OH and reached 12,000 ft. according to theOhio State Air Trooper Cessna 182 until running out of fuel. Landedin a soybean field in a spiral. Messed up everything except the left frontstrut and left aileron, & left main gear leg. What a sick feeling he musthave had watching that thing solo without him.

He showed me a news articleof one that took off in Ohio. Travelled 100 mi., climbed to 11,000 ft.then ran out of gas 1hr. later. The police were tracking it in aHelicopter. At one point they were going to get the military to shoot itdown but decided against it. It crashed in a bean field. It was anAeronca Champ.Regards, Domenico________________________________________________________________________________

Craig, Good tip on the propping from behind, I'm gonna remember that one. I used to hand prop my 150 when my starter died, and that would have made me feel a little safer! Bet you gotta pull pretty hard, good thing I'm economy sized!Thanks,Gary Meadows________________________________________________________________________________

Years ago in NF, one of the Skywagons (180/185) ended up in our old AME's shop with minor damage. The story that followed was quite amusing, afterthe fact. It seems that the low time pilot went to go flying but found thebattery dead. He had successfully hand propped a plane before and decidedto give it a whirl (pun intended). He cracked the throttle, turned on themags, untied the plane and walked to the front of the right float spun theprop. It started on the first blade. That's when our intrepid pilotrealized that by standing IN FRONT of the prop, he had no way to get backto the cabin! He jumped off the float and grabbed the rear cleat as itpassed by. Unfortunately, the plane was already building up a head ofsteam and the pilot wa susing most of his strength just to hond on.Firtunately, his body was acting as a rudder and helped to turn the planearound 180 degrees before he finally had to let go. The plane ended up onthe rocky shorline and holed the floats but did no other damage. The pilotswam ashore and shut down the plane. Unfortunately, the AME has since passed on and there is no way to verifythe story. However, it certainly sounds plausible.

Ken, if you get a Tiger Moth stand behind the prop to start it too! but onthe port side of the fuse. You can reach the mag switches from there.Our poor Tiger has a boo boo. A Military Sea King on its way to East Timorlanded beside it while the pilot of the Tiger was in the FBO's officesigning the fuel bill. The big chopper's rotor down wash spun the Tigeraround and the elevator hit the fuel bowser. I cut back the fabric to assessthe damage and I found the design much simpler than my GN-1's elevator. Itshould be easy enough to repair. The elevator capstrips are glued and nailedto the spar and a small wedge shaped block is fitted between them at thetrailing edge. There is a small spacer of ply and the trailing edge is analuminum tube held to the blocks by an aluminum strap. Simple! The Crown may pick up the repair tab (Might make me feel better when Isign my tax return) The Chopper pilot admitted his manuvering withdisregard to the other aircraft on the ramp. I guess he is still learningabout being out in the public. He said he thought the Tiger was tied down.Do you know of anybody tying down at the fuel pumps?J Mc________________________________________________________________________________

Several years ago, my wife bought me a T41A for my fiftieth birthday. The catch was, it was in a basket (actually, several). Seems a young MD owned it after it was mustered out of the CAP. Decided to go flying one day, battery dead, etc., etc. The lad was lucky. The airplane knocked him out of the way without hurting anything but his wallet and his pride. However, when the poor Cessna hit the FIRST airplane, it was reported to be eight to ten inches off the ground!Rebuilt wing, new prop, new tail feathers (? I'm still trying to figure that out), new windshield and lots of other stuff, my mistress has been flying a couple hundred hours a year ever since. Has the battery ever gone dead? Of course. Have I ever hand propped it? You betcha! How? I TIE THE DAMNED THING TO THE BACK OF MY PICKUP BEFORE I SET THE BRAKES!! Has it ever tried to run over me? Not yet.By the way, my wife used her OWN money to buy me that wreck. Even though she doesn't like to fly single-engine any more, I think she's a keeper.Ed________________________________________________________________________________

This is a slight departure from the subject and I would hate to cause aserious snicker attack for all you pureists. Anyway, I was havingtrouble with the first engine startup on a Morry Hummel 1/2 VW that's onmy RW-6. I was none to secure about this hand propping business and wasnear dieing from over exertion when my hanger mate (an old guy comparedto my 60 yrs) suggested that I use the bungie cord method. RIGHT!!!Start it with a rubber band...... Well he explained how to do it and itworks. I had an old leather glove that I put a small rock in the thumband tied three 18 in lengths of surgical tubing to the thumb (bungiecord would work better). Then you just slip the glove over the end ofthe prop and standing off to the side, give it a pull. The surgicaltubing stretches until the prop starts moving then it snaps the engineover far faster then you can do it by hand. As the prop comes around,the glove slips off the prop tip and out of the way. The best part isthat I never have any part of my body within the prop arc. Super simpleand safe. This is especially important to me since I have already usedup eight of my original nine lives. The worse thing that can happen isto hit yourself in the leg with the glove when it snaps off the prop tip(use a really small rock).Of course I don't consider the spectators rolling around on the groundlaughing as being a dangerous thing.John W -----Original Message-----

Gary,Nope, doesn't take a lot of strength to prop from behind. I did it all theway from Florida to the Canadian border and back this summer.It is probably all in the wrist. You want a fast snap. Maybe my tennisserve played a part? Also, the secret to all hand propping is not to propfrom the tip of the prop. I see people try that unsuccessfully all thetime. Come in about 1/3 of the way toward the hub and do your pulling. Youcan generate much higher prop speed and therefore a successful start.Ted BNaples, FLGN-1----- Original Message -----________________________________________________________________________________

Sorry to hear about the Tiger Moth. Recommend you take many photos of thedamage and repair process. You will probably do better to do the repairsand submit the bill as the payment might be some time in coming. Am starting on my landing gear today. Bolted on two of the attachmentfittings yesterday. I've been arc welding all of my .096 fittings as Itrust my arc welding more than my gas welding. Planning on using the largestruts off a Cub for my V's. With the nice weather I've been able to pretty much complete the majorwoodwork on the fuselage. Glued on the second ply side the other day. I've put 1/8 birch ply over the top of the cockpits/insr panels as I'veheard the aluminum takes a beating from people getting in and out. Itturned out very nice. Any thoughts on what to use to protect the woodwork? I'm thinking ofusing something like thompsons water seal with a top coating or three ofwhatever urethane is compatible. Seems to me the newer wood protectors oreven a good soaking of linseed oil would do better than straight varnish. Comments? Any chance it would affect the glue? (using West System)Wayne SippolaWinnipeg MBPS: sign me up for the IPA. Expect to complete for under $5000 Cdn ($3200US)
