In reality, Congress mandated ELTs two years earlier,
after lawmakers in California and Washington moved to
require ELTs in response to the discovery of a crash survivor weeks after the plane disappeared. While opposition
ran high in the FAA and the pilot community, Congress
acted to preclude a patchwork of state laws encroaching
on the FAA's regulatory turf - much as it's defending its avionics authority against encroachment by the Federal Communications
Commission.

Reduced Options Available: Hold or Change

The FAA long ago terminated TSO-C91 for the earliest
121.5 MHz ELTs and replaced it with TSO-C91a - now also
terminated.
In canceling TSO-C91a, the FAA also acted to cancel
TSO-C126 and TSO-C126a authorizations, in part specifically addressing its withdrawal of approval for future installations of mounts employing hook and loop retention to
keep the ELT in the mount. In its filings, the agency
noted, "The FAA is taking this action based
on its determination that hook and loop
fasteners are not an acceptable means

of initially expensive solutions rapidly giving way to less-costly, more cost-effective options.
And those groups continue their opposition to even putting
a sunset date on allowing 121.5 MHz beacons to satisfy FAA
requirements for emergency locator beacons, even knowing no
satellites monitor the frequency.
Thankfully, the availability of new solutions helps to further push down the life-cycle costs of GPS-enabled 406 MHz
ELTs to equal that of the old 121.5 MHz models still flying.

A Growing List of Options

Consider suggesting some of these options for adding a superior ELT to your customers' aircraft - and note the benefits
they all enjoy: global satellite monitoring, higher accuracy and
near pinpoint position data from GPS-informed models of the
406 MHz ELTs.
ACK, Artex and AmeriKing
This trio of long-time ELT suppliers has kept up with the
times, moving into TSO-C91a units when they became the
dominant technology and following into the 406 MHz TSOC126b-approved units.
From ACK Technologies, one choice is the ACK 406/121.5
