Very extensive report is provided within a week. I've been doing it with the filter every annual and just the oil at every change. I know, it's over kill, but it keeps me happy.

Are others doing this? If so, are you having the filter done too? Who do you like and what is the cost? This is all new to me so I need some guidance. I am at 14 hours and it looks like I am going to be able to get the temps on the Jabiru under control, so it just may work out. > > Best to all for Christmas and the New Year. > > Jim Puglise > N283JL - flying off my 40 hours > > > > ________________________________ Message 3 _____________________________________ Time: 02:21:43 PM PST US From: "Bud Yerly" Subject: Re: Europa-List: Will, Max prop diameter is still 64 inches recommended. This is based on the prop clearance of course. In the tri gear clearances are based on spring or bungee with the by the book cable stop dimensions per the build manual. This leaves nominally 10-11 inches from the prop tip to the ground (aircraft unloaded, nose tire inflated at 35 psi. and the CG at 60 inches) in most of my aircraft. At full deflection of the gear at full gross weight, this gives 7-8 inches of clearance. (Yours may be different due to main gear installation.) FAA requirements for minimum propeller clearance: Sec. 25.925 Propeller clearance. Unless smaller clearances are substantiated, propeller clearances with the airplane at maximum weight, with the most adverse center of gravity, and with the propeller in the most adverse pitch position, may not be less than the following: (a) Ground clearance. There must be a clearance of at least seven inches (for each airplane with nose wheel landing gear) or nine inches (for each airplane with tail wheel landing gear) between each propeller and the ground with landing gear statically deflected and in the level takeoff, or taxiing attitude, whichever is most critical. In addition, there must be positive clearance between the propeller and the ground when in the level takeoff attitude with the critical [tire(s)] completely deflated and the corresponding landing gear strut bottomed. Europa nominal clearances: If installed by the book at 2 inches (full cable extension), crossed properly so the cable cannot slip off, with a deflated nose gear tire, there is at least 4 inches of clearance on my new builds putting a full 300 pounds on the front of the engine. That will keep you from mowing the grass and or plowing a furrow with your 64 inch propeller if the nose gear tire fails on a rough landing or rough strip. 12 AY flew with the gear leg bolted solid in an attempt to install a longer prop. I don't recommend it. It's a bit harsh on a rough strip so to prevent fatigue I installed the springs shortly thereafter and shortened my cable stop to allow a total of 1 inch of movement until contact and a bit more on full extension. Longer answer on install and extended life operations notes: On installation, Chapter 29T says to pull the gear leg up (without springs or bungee) and swag the cable at two inches from the stop to the leg. I clamp (using a bolt type cable clamp) the cable at that distance with the gear leg pulled to check full tension on the cable. When satisfied, I then swag the cable. This gives 8 inches clearance as stated above. In the field, because the spring or bungee is attached normally, I use the one inch (two fingers) method to check if I need to re-swag the cable because of poor installation or cable stretch. I find the cable easy to pull down firmly from under the aircraft and check the distance. To check the springs I place my full body weight (180 lbs.) at the hub to deflect the springs the full amount for a quick check. When doing maintenance on other aircraft I have found that the cable will stretch a bit more than new which puts more strain on the springs. Occasionally I have seen on trigears which have operated extensively on grass, and the cable stop either was installed improperly or it had loosened and had not worked as advertised (it slipped off the lower leg) and this caused the springs to become weaker under severe grass strip operations. (Thirty pounds at the hub caused the springs to deflect which is unacceptable.) It is not fun to cut those springs off and replace them because they no longer hold the nose gear firmly on the stop. So it was a personal decision to go tighter than looser on the cable stop to prevent this from happening.
