KR> Selecting an airport to be based at
My hangar lease agreement stipulates that fuel or combustibles outside the aircraft fuel tank(s) may not be stored in the hangar in any quantity. It's not really to protect the nearby FBO who has a self-service avgas pump that has never pumped anything that costs less than $4/gallon, it's to protect the other hangar owners, most of whom have airplanes that are worth more than 15x what my little Pietenpol with an A75 and 16 gallon fuel tank are worth. Directly behind me, for example, and only the thickness of one layer of corrugated sheet metal away, is a gorgeous Beech Duke. In the row of hangars across from me are a couple of Cirrus's, an RV-8 whose instrument panel is probably worth more than my house, and directly next door to me is a Cessna Skylane that I would have to work all of my remaining lifespan to be able to afford after paying my own bills and the undertaker's bill. A couple of 5-gallon totes of $2/gallon mogas in my hangar could bring those differences in value to the immediate forefront if they were to spill and ignite. Oscar Zuniga Medford, OR
KR> 15 year life on Control Cable and fittings
As Sid correctly points out, all the listed fittings are Swaged fittings. When the cable is swaged inside a sleeve, it is impossible to inspect inside the sleeve for corrosion. Per plans, I made all the cables in my KR with a thimble and loop with a copper Nicopress sleeve, which is not called out in the CASA A.D. Unless you ordered your cables pre-fabbed from a vendor, it is highly unlikely that any of the KRs have swaged fittings. Swaging takes some rather expensive special equipment (I have several swagers at work). -Jeff Scott Los Alamos, NM > > All of the control cable fittings called out in the Australian AD are roll > crimped terminations.

KR> 15 year life on Control Cable and fittings
Maybe a tensile test at 80 percent of the yield strength would satisfy any fears of internal corrosion? Seems a shame to toss them out arbitrarily without knowing if they are internally corroded . Just a thought as I have a few in my KR2S ,as I recall. I use them on the rudder horn where appearance of the swaged type is better. And I recall using a swaged cable at the aileron bellcrank where is goes through the rear spar. Hmmm..?

KR> Selecting an airport to be based at
I've been running the 8.5:1 compression O-200 in my KR and the 8.5:1 160 HP O-320 in my SuperCub clone on a diet of 100% E0 premium fuel for the last 2 years. I have a tank with filter, grounds, and electric fuel pump that is anchored in the bed of my truck. Nobody at the airport (including the airport manager) has said anything about it other than they wish they had the same setup. I do make it a point to use safe practices for fire mitigation like never fueling in the hangar. Previously, one of the other pilots proposed to park his truck on the ramp at the airport with my tank in the back to be used for fueling. Of course the airport administration went liability crazy and denied his request. When I decided to start using Mogas, I didn't ask. I just made sure my fueling rig was configured with the proper venting, filter, ground, and pump for the application and started using it. I also keep it painted and nice looking. They never questioned it. It looks exactly the same as the fueling rigs hauled around in many pickups for fueling farm equipment out in the fields, except cleaner. :o) As Mark says, you want to start out with 100LL until you find whether you have cooling/vapor lock issues and what your detonation margin might be. -Jeff Scott Los Alamos, NM > Paul Visk wrote: > > >>I'm starting to look for airports in the area to base my airplane at.

All of the control cable fittings called out in the Australian AD are roll crimped terminations. The internal areas of the terminals that grip the cable are not visible for corrosion inspection. Nothing in the AD about Nicopress or similar cable crimps. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA Hi guys CASA has released an AD in Australia limiting control cable life to 15 years, this seem to include building time on some fittings. I have added the AD number and link below. Does this indicate the parts need a Date of Manufacture stamped on them from now on? Phil Matheson AD/GEN/87 This Airworthiness Directive became effective on 1 February 2015 and will apply to all the amateur built aircraft fitted with the stated stainless steel cable hardware. Please read the AD carefully to determine how/if it applies to your aircraft. Mike Horneman has written an excellent article on this subject which will appear in the next Airsport edition. Although the AD mandates replacement based upon ?time in service?, the SAAA recommends that you consider the circumstances carefully if you project had a long gestation period. If not properly stored, the damaging corrosion can be still be occurring whilst your project is under construction. http://www.casa.gov.au/ADFiles/airgen/gen/GEN-087.pdf -- Time in service is for the cable assembly, not the individual pieces, and is based off the aircraft manufacture date. The clock starts after the aircraft is signed off as airworthy, and repeats every 15 years. (technically). If you live on the coast and the project is taking 10 years to complete, consideration of cable assembly deterioration must be taken into account. As an alternative, using MSG-3 methodology (maintenance program) will allow a potential extension. I don't see MSG-3 as an option for the KR builder. Darn. Roger Baalman rbaalman at cox.net

I purchased a clean 55 gallon metal drum ?that I keep in the hanger. ?I put it on my trailer when it is empty to transport it to the pure gas station with inexpensive 91 octane. ?I have a hoist that hangs from the ceiling that I use to unload it from the trailer. ?I transfer the fuel to a 5 gallon can that I use to fuel the aircraft outside of the hanger.?

I operated my B33 out of two public airports in OR for years. Realize that with aux tanks I could transfer as much as 80 gals of mogas at a time. I used approved plastic jugs that frequently filled my car trunk and back seat. I was discrete and safe, and completely unchallenged. I heard that federally-funded airports had to allow self-fueling. Never had to ask. Peter

Paul, I don't think that they search every vehicle. Lots of folks here do there own fueling. Don't be overtly obvious about it.
