"I was bothered by one of the pictures which showed that the
trailing edge shear web had been cut all of the way through the bottom
skin to the upper skin"
I certainly understand your concern! On the 360 MkII it is
necessary to cut almost half way into the T.E. shear web. According to
the manual this is normal and ok. The reason my T.E. shear web is cut
all the way through is that my elevator skin layout called for the
servo to be installed in the bottom skin from the outside, so that the
servo itself would also be the cover plate. The reinforced area for the
piano hinge was, however, also on the bottom skin, which, despite
encouragement from Lancair, made this installation impossible due to
bending forces on the servo arm. I, thus, had to relocate the servo to
the inside of the upper skin, which necessitated a nice cut into the
other half of the shear web.......
I will, of course, close the unnecessary part of the cut with the
required amount of BID and should have pointed this out in the previous
message. Unfortunately I am momentartily not able to check up on the
correct amount of BID, my manuals are in storage because of a
house-overhaul ( my wife issued a SB stating that the TBO for kitchens
and bathrooms is now down to 30 years ).
