mode.
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 accord-
ance 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
