Overhead cabin transitions from Evaporator

March 16th, 4 hours. I received back the molded transition piece from John at Flightline AC that was produced from the transition piece I made. Overall the piece looks fantastic but we both knew the piece would need trimming to properly fit since they made the transition piece based upon little to no extra information. In one of the pictures you can see how the original intent was to be, however based upon this installation and many other likely to follow for others the transition piece will need to be modified a bit more to be mounted much higher. I trimmed off the top portion of the piece that wraps around the evaporator. I then lowered the inside backing wall that helps seal the evaporator face to the transition since I had to raise the entire tranission up higher. The tranistion now mounts up to the overhed, evaporator and cabin top very nicely. I still need to locate a mounting plate for the front mounting hole already in the evaporator and place a rubber or foam gasket material on the surface that require to be sealed. I think John will revise his mold slightly to accomidate the angle differences but overall the tranisiton piece is very near it final shape.

John placed to vents in the transition piece to help throttle the air flow plus allow the cold air to be more quickly recirculated thru the evaporator to help cool down the cabin quicker and achive an overall lower temperature.

Fuselage Section 43, Cabin Cover

Section 43, Cabin Cover

I started working with the cabin cover. The first day i worked approximately 6 hours rough cutting the cabin cover after I traced the scribe lines. The second day I took the canopy outside to finish rough cutting the door openings. I then placed the cabin cover on the fuselage and checked the fit. With a little more trimming and sanding with a belt sander I was able to fairly well fit the cabin to the fuselage. This took about 3 hours. I then drilled the #30 holes into the cabin top thru the F-1074 Tailcone Forward Top Skin and clecoed as i went down the sides. I then moved from aft to the front of the fuselage drilling each hole in the side skin and then into the cabin cover. After that I started working on the door entries and secured them to the fuselage and drilled the appropriate sized holes as called out in the plans on page 43-5 and 43-6. This took bout 3 hours. I then placed the WD-1043 Center Cabin Brace into position for mounting it between the F-1071 Fwd Top Skin and the cabin cover. Drilled the #12 holes into the cabin top and then into the brace located under the F-1071. This took about 30 minutes. I experienced my first tool failure of this entire build when my small angle drill attachment failed. Total time for this write up is 12.5 hours.
