MX20 Installation Manual
mounting tube P/N 310-0429-01, or later FAA approved revision, is recommended for all installations
and is required for helicopter installations.
The MX20 does not require external cooling. When mounting the MX20, leave a clearance of 1/8 to 1/4
inch between avionics to allow for air circulation.
For installations where a stack is not already installed in the aircraft or the alternate mounting
configuration depicted in Figure 2-4 is implemented, a separate structural approval is needed for
installation of the stack. Any other alternate mounting configuration is beyond the scope of this STC.
