DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL
B406-4 (453-5004)
(2) Locate the mounting tray such that the ELT mounting frame cap has at least 5 inches (127
mm) of clearance for installation and removal.
(3) Mount the ELT as far aft as practical, but where it can be easily retrieved for maintenance.
NOTE
: Statistics show that the tail section of an airplane is likely to be less damaged during
a crash; therefore, providing a good mounting environment for the ELT.
(4) Additional installation guidance may be found in AC 43.13-2, Chapter 2, Paragraph 28, which
specifically addresses ELT installations.
