The ELT installations on the small Bells are notoriously un-crashworthy.
a common problem.
on the '47's we used to mount them out of harms way on the tail boom. now they are often mounted inside the xmon bay, with their own aerial folded and connected to a remote aerial which either gets whacked off in the crash, or the whole unit burns. A very fragile arrangement.
That's why we usually prefer to carry personal variants, guessing that if we survie, we can excite the ELT and throw it out.
We need a device invented, mounted externally somewhere, that is triggered either manually or atuo to eject aways a bit and go off on contact with terra firma.
