L-3 Aviation Recorders is now offering an underwater locator beacon that is in compliance with the TSO-C121b 90-day operation standard.
As a convenience to our customers,
L-3 is offering 90-day beacon retrofit kits that allow you to remain in factory Component Maintenance Manual (CMM) compliance while updating products in the field. Included in the kit are Manufacturing Inspection District Office (MIDO) approved installation steps to make the upgrade easier.
Support of legacy equipment remains available with battery exchange kits for 30-day beacons until the beacon becomes unserviceable.
