Recess Mounting the EFD as per Figure 6-4
These are partial instructions for accomplishing the aircraft modification to permit recess
mounting the EFD1000 E5 displays using Aspen Avionics Recess Mounting Kits. Recess
mounting of the EFD displays can be done for cosmetic reasons or for clearance when the
flight controls are in the full nose down position. This data, and the information found in
AC 43.13-2B Chapters 1, 2 and 11 normally is sufficient data to accomplish the
modification.
This section contains instructions for preparing the instrument panel to accept the EFD in
a recessed mounting. This data is approved for the structural aspects of the instrument
panel modification; however, by itself, it may not be sufficient data to address all aspects
of modifying the instrument panel of an aircraft. These instructions and the data in
AC43.13-2B chapters 1, 2 and 11 is normally sufficient data to complete the
modification. In some cases (for example only, if the instrument panel supporting
structure, structural attachments, or a structural instrument panel are modified) then
additional data will be required. In those cases where this data is insufficient then these
instructions, combined with additional data to accommodate individual differences in an
aircraft, can be presented to a Structural DER or Regulatory Authority for approval. If the
data package is satisfactory, the DER or Regulatory Authority will approve the data for use
in the modification of the instrument panel.
Once all necessary approved data to accomplish the panel mounting is obtained, and the
modification is accomplished, the EFD1000 E5 installation can proceed in accordance with
AML STC SA10822SC or other regulatory approval process.
One Recess Mounting Kit is required for each EFD display.

Recess Mount Modification Procedure
STEP 1 – Evaluate the Installation and Determine if Sufficient Approved Data is Available to
Proceed
Normally, the instructions in this section and in AC43.13-2B Chapters 1, 2 and 11 are
sufficient data to complete the modification. If the data is not sufficient, such as, for
example the instrument panel structural supports are affected or the panel itself
provides structural integrity to the airframe, then additional data must be developed
and approved. If additional data is required, collect and prepare the approved data
necessary to substantiate the alteration before modifying the aircraft.
