I hope not! *Limited access maybe, but certainly not sealed.

I recently looked really hard at the ASW27 tail, to try to put the
transponder antenna in there. So far, I've concluded it can't be done
without cutting holes. The closest I came was putting small antennas
like flarm and transponder in the tail battery compartment and fishing
the coax down where the TE tube goes, but the tail is sealed off from
the fuselage boom so I couldn't see how to get the coax through
without cutting holes. Of course if you're willing to cut holes, it's
easier.

If anyone figures out how to retrofit antennas in the tail without
major surgery, pass it on!
