Bases
____ 1. Are transformer housings of the correct type, size and material?
____ 2. Are transformer bases installed level, to proper grade, and with proper bolt pattern
orientation?
[Tops of transformer housings should be slightly above surrounding grade in non-
paved areas, or flush with grade in paved areas (to keep water away from covers).
There should be smooth transition between concrete envelope and surrounding
grade. Allowances must be made for spacer rings or pavement rings where used.]
____ 3. Are transformer base cover gaskets properly installed, with all bolts properly
torqued? [Use only stainless steel bolts; do not reuse shipping bolts unless so
intended by the manufacturer.]
Lights
____ 4.
Are all equipment and materials new, and as specified? Are lamps and isolation
transformers of proper wattage? [Items covered by the FAA L-800 series should be
listed in the FAA AC 150/5345-53.]
____ 5.
Are all light locations in accordance with the plans?
____ 6.
Are the correct filters installed and light lenses properly oriented for runway edge
lights? For threshold/end lights?
____ 7.
Are the light lines at proper distance from the pavement or defined edge, in straight
line within tolerance?
____ 8.
Is the height of light fixtures in accordance with the plans, and breakable couplings
properly installed?
____ 9.
Are all lights plumb and are their heads tight and level? Are bi-directional lights
properly oriented relative to the runway? [Bi-directional lights have toe-in and must
be oriented properly relative to runway.]
Cables
____ 10. Are L-823 connectors of proper size for the cable, and are field attached connectors
applied properly per details (taping/heat shrink)?
____ 11. Are all L-823 Type II two conductor secondary connectors Class A (factory molded)?
____ 12. Has grounding of light base been provided in accordance with the plans? Are
ground rods installed to at least minimum depth below grade and within maximum
spacing?
____ 13. Is counterpoise properly separated from light bases and base grounding provisions?
[The counterpoise/grounding policy may not be the same at each air base. Ensure
compliance with plans.]
System
____ 14. Are lights labeled in accordance with approved numbering scheme, with proper tag
and size of numerals? Are edge light numbering tags facing the pavements?
