I still haven't done Mod 62 or 70 as everything seems tight and secure back there and at

 220 lbs I really don't relish the thought of working inside the tailcone so I would like to add

 an access panel that would facilitate these mods, as well as gain access to the elevator

 trim mechanism.  Could anyone recommend a size and location that might allow this?

   I've seen some round panels that look helpful.  I'm right handed so would it be best to

 put the panel on the port side or would I need panels on both sides?

I dont believe it is possible to do mod 70 easily without  crawling down the back of the tailplane (IMHO). If you arent able to get in  there yourself (and I accept there are many who cant), then I would suggest you  find a friendly midget who would be willing to assist (its amazing what kids  will do for a bit of pocket money).

  

 The standard inspection panel is about 6ins in diameter  but by the time you make the flanges for the cover to fit against you only end  up without about 5ins to put your arm through. Its ok for inspection but not for  much else - and for you to hand the midget cups of coffee (and tools) to prevent  them from falling asleep on the job.

  

 I am pretty slim myself but correspondingly long in the  body - I weigh 200lbs and 6' 2"". I managed the mod by crawling down the back  but as most folks will testify it isnt an experience one wants to repeat.

Glenn, 

 

Adding access panels will not be an easy job, especially with all the re-inforcing work required. 

 

Would be money well spent to find someone young enough and small enough to do the work, it does not take too long. 

 

If you go into the back yourself, take a cell phone or have someone check regularly. I had visions of expiring there and being found a few days later.

Glenn,



You hit upon something I have been thinking about for a long time: a large 

access panel right on top of the fuselage at the root of the fin, and 

eliminating at least one of the other two mickey mouse openings, and giving 

easy access to some very important components for future maintenance. Of 

course the rim would have to be re-enforced in order not to weaken the 

fuselage.

Isn't there a stress engineer around who could do the calculations and 

design a mod for submission to the PFA ?



Karl

And after fiddling in the back 3 mths or  ago, I still have a tingle in my right thigh where I had my groin across  the sharp edge of the b.b. opening and stirred up the nerve in my  leg.

  

 I am not wanting to get back down  there.

Glenn,

  

 I just finished installing Mod 70. I don't know how I would have done the  job without the two access holes in the tail on the starboard side (for my plane  as I'm right handed). The forward most one is called for to be 4 inches in  diameter. The inner ring for the screw plate brings this down to less than  3 1/2 inches and was very tight on my forearm. The rear "Viewing Hole" I have  increased in size from 2.5 inches to four inches also. But this called for a lot  of (4 plies of BID) re enforcing all around for about 4 inches out from the  holes edge. I also added two more plies forward of the view hole to span the  underside of the horizontal stabilizer's front edge. But when I did Mod  70, I had yet to add the inner ring for the screw plates to the viewing  hole, so I had the entire 4 inch diameter to work with. My size precluded me  from crawling far enough into the back to enable me to do the job....even though  I have installed two cleats on the sidewalls just forward of the Mass  Balance tower for a removable shelf that I could work on my elbows on. I  also needed a drop light (car engine work light?) in the rear and set up a fan  to blow cooling air through my front window (windscreen not yet installed), all  to keep me from having a claustrophobic episode while working inside the  tail. All this because the price of monkeys and skinny little kids has just gone  through the roof in my area. A call or email to Europa might get you a little  more info on any other possibilities or anything that you should not do. I hope  this helps.

Me either. What a breeze this mod is going to be!

I've spent a lot of time in the back since EFIS CPU was mounted there and to do Mod 70.  What I found was that a cardboard box in the baggage bay the same height as the bottom of the D opening supported my stomach comfortably and kept the sharp edge of the opening from cutting. My legs ended up between the headrests.

The attached drawing is of the "sled" which I use for access to the rear

of the Europa.  Works very well and cost little to make.



I hope this helps
