Any nose gear will fail when stressed beyond it's design limits.

You can usually spot it by the bright finish. I should look it up and spout exact numbers, but it's basically half of the strength of 6061-T6, so don't use it for anywhere structural if you can help it. You can also tell 6063 when you drill it. 6063 just sort of crumbles, whereas 6061 will spiral out around the drill bit in long strands, refusing to let go...

One must remember to protect the nose gear by continuing the back pressure increase throughout the flare until the nose settles on its own, or damage can occur. The Grumman Tiger, Cheetah, Traveler, and Lynx all have the same type nose wheel, and it fairs them well, but is the weak link. This is where I have preached that one NEEDS to learn how to fly into ground effect first, and then establish a landing attitude followed by a gradual flare as the airspeed bleeds off. All too often pilots get in a hurry to get into the flare attitude on the descent, and they are very near the stall when they enter ground effect. They try to continue flaring only to find too little airspeed, and too little elevator left to flare, so the nose drops as they drop crashing to the runway, smashing into a 3 point which overloads the nose gear. Descend down final, round out into ground effect and pause as you fly in ground effect with the performance increase, and then begin the flare at the point when you begin to descend again. Works on every plane I have ever flown! Happy flying....

If it's home built. .well. Also, if it's a Diehl and it collapsed, it is possible the owner didn't install it properly. The best thing to do is ask the seller how he did the nose gear in. i.e.: Did he come in hot and plant the nose before the mains? Did he run off the runway/taxiway and/or hit some "thing" with the nose? I'd mainly want to know how and why the nose gear collapsed. Just my two pennies worth.

Some of the early Diehl nose gear struts were made of fiberglass. These were prone to snap off with any shimmying. I believe Diehl was offering to replace those early ones with steel ones for no cost. You MUST treat the nose gear on these planes with tender loving care. I had a friend that knocked his nose gear off several times due to his landing technique. He thought you just got close to the runway & let the airplane land itself.

The FAA Handbook AC 43.13-1B Chapter 7 indicates a maximum loading of 40,000 PSI when proper recommended nut torque is applied. AC 43,13-1B can be down loaded in pdf format from www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf which may take a while since this handbook has lots of charts and illustrations. Now for the soapbox: If you are not following the recommendations of AC 43.13-1B or similar document, you will indeed have an 'amateur-built' aircraft.

You probably already know this, but you will be buying a project that has 90% of the easy work completed and has 10 % remaining. That 10% has to equal 51% of the real work in order for you to be able to certify the aircraft. Make sure you have enough documentation to justify your 51%. Since 49% has been completed, you must go over everything to ensure you are willing to fly what is there. Unless you know the seller, I would even open the engine, unless WW will put his name behind it. Look for things that could cause you severe problems if they fail. Some items would be: wing attach; gear attach; all flight controls and the stick and rudder assembly; check all glue joints. The list goes on and on. It might be a wise bet to have another KR builder, an EAA tech counselor, or a licensed mechanic look at the project. It's hard to accept, but sometimes we look at something that we want to buy and only see ourselves punching holes in the clouds, and not as much of what it takes to make it safe. On the bright side, most builders are extremely cautious and overbuild. Your project probably falls into that catogory. This is by no means a complete list. Good luck. Orma L.

I first flew in 1984, and currently have somewhere around 500 hours on my type 4. In 1991 shortly after takeoff I discovered that I was using cheap cylinders to obtain 2000 cc. One failed under the head and I made a forced landing on my home airport. I never considered the math when I installed new cylinders. (the largest that would fit without cutting the case, 96 mm). After the repair the engine only had 1910 cc. I have run the engine that way for the past 13 years. I had to lap a couple of valves a few years ago and other then trying different carbs, props and different Ignition systems, the engine is the same. I did not have a lot of data on the engine, only that the person who assembled it had a good reputation(BS). I tested the engine as part of a condition inspection and found that numbers 2 & 3 had exhaust leaks and number 1 was leaking into the crankcase. As of today I have removed the heads and pistons. I got my first look at the insides. The heads seem ok with no obvious cracks and the valves don't appear burned. The rings are all in tact and the cylinders seem to have little wear. I was amazed to see that looking inside the case, through the cylinder bore, at the cam and lifters, that the cam appears still highly polished with no marks at all. I did measure the lift of the cam and it lifts .317 inches and if measured correctly has a duration of about 270 degrees. The inside of the case seems to have some marks at the flywheel end which seems to have come from contact with the last crank journal. Perhaps my thrust bearings have worn enough to allow this scuffing. I will continue to investigate and make a report in a few days after the case is opened. Orma L.

The inside of the case seems to have some marks at the flywheel end which seems to have come from contact with the last crank journal. Perhaps my thrust bearings have worn enough to allow this scuffing. I will continue to investigate and make a report in a few days after the case is opened. Orma L.

That person would probably not be able to prove he/she had done enough work to get the mechanics certificate.

And, believe me, that last 10%, takes way more than 51% more work to finish. See N64KR at http://KR-Builder.org - Then click on the pics Daniel R.

MARK, what did you use if you did not find T5. I will need to make the horns but using Dr. Deans method of hinges.< Just use T-6, it's stronger anyway. Not sure why anybody would specify T5, when T6 is more plentiful and stronger in utimate and yield anyway. Are you sure you're not thinking of T651? That's pretty much the same thing as T6, as I recall. I used T6, and most other folks probably did too, whether they knew it or not.
