6.2 MOUNTING BRACKET KIT INSTALLATION
The Mounting Bracket Kit should be installed as far toward the rear of the plane as
possible to enhance its survivability in a crash. Rotary wing aircraft should mount it as
close as possible to the transmission or rotor shaft assembly.
It must be accessible to ground crews for servicing.
It should be accessible for maintenance removal and manual activation in the event of
an emergency.
It must be attached to a structurally sound, suitably flat and stable surface, with minimal
vibration.
The Mounting Bracket Kit MUST be mounted parallel to the line of flight and must be
attached to the aircraft with screws of a type suitable for aviation use.
All aircraft installing the AF model , must have the Mounting Bracket Kit installed with
the direction of flight arrow forward facing around the roll axis. For aircraft installing
the AF Model in a Helicopter, please note the aircraft bracket may be pointed
downwards up to a 45˚ angle to the yaw axis if necessary.
The drill pattern for the SkyHunter 406 TM mounting bracket is the same as the drill
pattern for Pointer Model 3000-10/11 and 4000-10/11 mounting brackets to facilitate
easier swap outs. Use the mounting bracket as a template or refer to Section 10 for
drilling pattern dimensions.
The following are mounting guidelines found in DO-204A in regards to ELT Mounting :
“The ELT unit shall be mounted to primary aircraft load-carrying structures such as
trusses, bulkheads, longerons, spars or floor beams (not aircraft skin) or a structure that
meets the requirements of the following test. The mounts shall have a maximum static
local deflection no greater than 2.5mm when a force of 450 Newtons (100 lbf) is applied
to the mount in the most flexible direction. Deflection measurements shall be made
with reference to another part of the airframe not less than 0.3 m or more than 1.0 m
from the mounting location.”
