It's said to locate the ELT as far aft as possible. The space on the Aft Deck is accessible under the Vertical Stab fairing. I borrowed this idea from Joe Waltz. I Started to make a bracket for the ELT in the tail cone, just forward of the horizontal stab on the aft deck using 3/4" angle aluminum and mounting the ELT bracket on top. Had to cut some holes in the angle bracket to route the elevator trim cables.
