Narrative:

When in the descent into MSL; we saw the runway and were cleared for the visual approach to runway 29. After lining up on the runway approximately 5 mi out; we realized that approximately 75% of the runway lights were inoperative. At approximately 500 ft we saw the runway and continued the landing. All of the other lighting systems were operative at the time of arrival. The runway light outage was not reported in the NOTAMS that were received prior to departure. Once the crew realized that there were that many runway edge lights OTS; a go around should have been initiated. While the actions of the crew did not technically violate the fom; because there were enough runway edge lights to identify the edges of the runway; it violated the spirit of the rule in that the lights were all on one end of the runway.

Narrative: WHEN IN THE DSCNT INTO MSL; WE SAW THE RWY AND WERE CLRED FOR THE VISUAL APCH TO RWY 29. AFTER LINING UP ON THE RWY APPROX 5 MI OUT; WE REALIZED THAT APPROX 75% OF THE RWY LIGHTS WERE INOP. AT APPROX 500 FT WE SAW THE RWY AND CONTINUED THE LNDG. ALL OF THE OTHER LIGHTING SYSTEMS WERE OPERATIVE AT THE TIME OF ARR. THE RWY LIGHT OUTAGE WAS NOT RPTED IN THE NOTAMS THAT WERE RECEIVED PRIOR TO DEP. ONCE THE CREW REALIZED THAT THERE WERE THAT MANY RWY EDGE LIGHTS OTS; A GAR SHOULD HAVE BEEN INITIATED. WHILE THE ACTIONS OF THE CREW DID NOT TECHNICALLY VIOLATE THE FOM; BECAUSE THERE WERE ENOUGH RWY EDGE LIGHTS TO IDENT THE EDGES OF THE RWY; IT VIOLATED THE SPIRIT OF THE RULE IN THAT THE LIGHTS WERE ALL ON ONE END OF THE RWY.
