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.
