tivity, verify that a 160 V, modulated 95% with 1300 Hz, signal will illuminate the amber (M)

push-button has been depressed. Select SPR for speaker to verify marker audio availability on the
cabin speaker. Verify that the white (I) and blue (O) lights will illuminate within  3dB of the amber

transceiver selected in the mic select switch. Depress the audio panel or yoke mounted playback switch,
and verify that messages play, in the order received. Repeat for COM 2. The playback will be stopped by

2.13 Final Inspection

Verify that the wiring is bundled away from all controls and no part of the installation interferes with air-
craft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accor-
dance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.
Complete documentation that may be required, such as a logbook entry, weight and balance computation and FAA
Form 337. Sample text for FAA Form 337, and instructions for continuing airworthiness can be found in Appendix F.
