COPA tried to talk Transport Canada out of mandating 406 elt's for all planes in Canada, but failed to convince the powers to be. Mexico the same.
This illustrates that nothing is foolproof, sadly.
Plane's emergency beacon failed in Alaska crash
The downed plane in Alaska was equipped with a state-of-the-art emergency beacon but it did not send out an alert, officials said.

A state-of-the-art emergency beacon on board the plane carrying former senator Ted Stevens did not broadcast its signal after the amphibious craft went down Monday in the remote Alaskan wilderness, a federal satellite tracking agency said Thursday.
If it had worked, a satellite passing over the area could have picked up the emergency signal within minutes of the crash and launched a rescue effort, said Chris O'Connors, program manager for the National Oceanic and Atmospheric Administration's Search and Rescue Satellite Aided Tracking (SARSAT) system.

The attempt to locate the plane did not begin for several hours and then was hampered as low clouds and rain closed in, forcing four injured passengers to spend the night in the wreckage, according to the National Transportation Safety Board (NTSB).
Five other passengers, including Stevens, died at the scene. The NTSB has not said whether any of the dead survived the initial impact.
General Communications Inc., an Alaskan telecommunications company that was hosting Stevens and others at its fishing lodge, had registered an emergency beacon for its DeHavilland DHC-3 Otter with SARSAT, O'Connors said.
The newest generation of beacons, known as emergency locator transponders, are highly accurate digital devices that have been credited with scores of rescues. They provide SARSAT with the location of an emergency scene and contact telephone numbers of family members or business associates so rescue attempts can begin promptly.
The devices were credited with rescuing a 16-year-old girl in the Indian Ocean in June after her round-the-world sailing trip was cut short by a large wave. They are particularly helpful for people stranded in the wilds of Alaska, said Lt. Shawn Maddock, operations support officer for SARSAT.
"In the two winters that I've been working here at SARSAT, it's probably been close to 20 snowmobilers (in Alaska) who were saved," Maddock said.
O'Connors said his agency has reviewed the data from Monday and could find no indication that satellites received any signal from the plane. Two satellites passed over the wreckage between 4:09 p.m. and 4:21 p.m., he said. NTSB Chairwoman Debbie Hersman confirmed that there was no record of an emergency beacon signal.
Accident investigators estimate the plane crashed between 2:15 p.m. and 3:30 p.m., but planes did not begin to search the area until about 7 p.m., Hersman said.
It's not clear why the beacon didn't send an alert. Models built for aircraft are designed to automatically send a distress signal after an impact from a crash. The units are usually installed near the tail of an aircraft. The tail section and most of the fuselage of Stevens' plane remained intact, according to the NTSB's preliminary reports.
