Jim I was not able to find specific statistics on accidents of aircraft landing short. What I did find is here at the ACRO site which compiles statistic for the world.

http://www.baaa-acro.com/Statistiques%20diverses.htm

It certianly points to pilot error being the leading cause for accidents.

Can you point me to any statistics which reveal that most short landings are due to fuel or mechanical issues? I need to change my thinking on this subject.

I think that is a great idea Lynn, one problem with the AC's is that they are very broad and long.

Paul - this has been updated since I saw it years ago. There is some good and relevant info in here. I like the flow chart. Maybe something that could be customized for our Quickies.

I have added a folder (Flight Testing Files) and file to the files section which contains FAA AC 90-109

I had hoped that there would be an option to allow others to add files to the folder as is possible with photos but it does not appear to be the case. So if anyone would like to add files to this folder contact me with a link and I will be happy to add them.

It will be a while before we have more details as to what caused the crash and with that said, landing/crashing short of the runway is usually caused by mechanical/fuel issues. One issue that is unique to plastic airplanes is the fuel filter being clogged by glass particles from the tank. No matter how clean you think the tank is, there will likely be enough material loosen up during flight testing to plug up the fuel filters (you do have more than one I hope). I recommend changing the fuel filters after the first flight and every 3 hrs for the first ten hours for a total of four times in the first ten hours of testing. This may be excessive but it is darn cheap insurance IMHO.

That is a great question Jim! I think the 6000' runway plus flying up over the airport and staying there until all of the slow flight characteristics are mastered is a must along with all of the things Lynn posted. We still don't know what happened to Jerry's flight so until that bit of info comes out we won't know what we can do to take that out of the equation.Hey can I be your friend Jerry Marstall? Doh, wait already am!Bruce

Jim,
Good question. When I get my normal PC going again I am going to forward the agenda that i used for my first few flights Since the beginning of time, the first flight landings have always been the most problematic. So my focus was to do enough airwork to setup a good landing. Things like knowing your aircrafts slow speed characteristics, pitch-buck tendencies, trim setup, aircraft setup that establishes the proper descent rate, etc. My first flight agenda called for a minimum of three simulated approaches before final landing. More if that's what was needed to get approach and round out right. The caveat here is that on first flights, the engine cooling / performance may not allow you to do as much airwork / landing setup as you would like.
Not saying my approach to all of this is the right way, but is simply one persons methodology.

When testing a new plane/pilot combination should you be focusing on the landing phase or touch and go's
or should you be doing your basic airwork???

Since we don't know what happened yet to Jerry's flight it would be interesting to know if it was actually pilot error or something came loose in flight or engine out. Jerry had already landed several times with some amount of success.
One of the points I want to make in the test flights at first is this....you need at least a 6000' runway (longer would be better). With that length you could have an engine out and still make the runway. Unless you are trying to fly a long downwind and "drag her in" to give you time to set up. My attitude is the Q should be set up every flight for an emergency landing "spiral down" from the "Perch". We won't know for awhile what happened to Jerry Brinkerhoff but Jerry Marstall's advice comes from lots of military experience and I have called him for advice when I needed help.
My 2 cents worth
