Subject :      Request for Special Temporary Authorization (STA)
               High Intensity Radiated Fields (HIRF) Threat Development – New Century, KS
               Reference: 0372-EX-ST-2014 (Current Project)
               Reference: 0919-EX-ST-2013 (Previously Approved STA for similar project)

This request for a Special Temporary Authorization (STA) is submitted in accordance with CFR
47, part 5.61. The purpose of this STA is to perform Low Level Swept Coupling (LLSC) testing on
a Part 23, 25, 27, or 29 aircraft for the purpose of aircraft threat development for a High Intensity
Radiated Field (HIRF) environment. The threat development determines the required equipment
bench test levels. This test is required to satisfy the HIRF certification directives found in Exhibit
2. Further details are provided below.

Need for special action: The tests to be conducted include the use of swept frequencies from
500 KHz to 18 GHz with the exception of prohibited frequency bands. Testing using widely
spaced discrete frequencies would miss possible critical resonant frequencies. The proposed
testing will include the following.

From approximately 500 KHz to 400 MHz, the aircraft under test will be illuminated with a known
low level swept frequency electromagnetic field and the resulting induced cable bundle currents
will be measured on the aircraft using current probes.

From 100 MHz to 18 GHz, the aircraft under test will be illuminated with a known low level swept
frequency electromagnetic field and the resulting electromagnetic field strengths will be measured
within the various compartments of the aircraft.

Time and Date: Testing is planned to occur between the dates of May 12, 2014 and November
12, 2014.
Location: Proposed testing will occur at the Garmin flight test facility at New Century Airport,
New Century, KS. This is a company owned facility at the coordinates N 38° 50’ 33”, W 94° 53’
39”.
