Narrative:

I was the PF for a normal night ILS with low ceilings (100 AGL) and low visibility (1 1/2). The ILS was established at the correct airspeed and flap setting. I was able to maintain the localizer and GS down to mins of 200 ft AGL + 1/2 mi visibility. The problem began when I tried to transition from instrument flight to night VFR with fog. I never gained any depth perception or outside references, and the runway was washed out by a mixture of the fog with the runway lights on high intensity. Without any visual references, I began to drift to the right of the centerline at approximately 150 ft AGL. The captain said, 'my aircraft' and took control of the aircraft. In doing so, he corrected to the left bringing us to the left of the centerline. After touchdown, our left main gear left the runway striking 2 runway lights. He was able to land normally and bring the aircraft back to the center of the runway with little effort. The contributing factors in this situation were: late night flight, fog, low ceiling, high intensity lights combined with fog, the pilot unable to transition from night instrument flying to night visual flying in close proximity to the ground. In order to prevent this from happening in the future, the pilots should be trained to transfer control of the aircraft to the pilot who has been adapted to outside references to complete the approach when the WX is down to mins.

Title: LOW MINS LOW VISIBILITY LNDG BY MDT ACR ACFT -- HIT RWY LIGHTS.

Narrative: I WAS THE PF FOR A NORMAL NIGHT ILS WITH LOW CEILINGS (100 AGL) AND LOW VISIBILITY (1 1/2). THE ILS WAS ESTABLISHED AT THE CORRECT AIRSPD AND FLAP SETTING. I WAS ABLE TO MAINTAIN THE LOC AND GS DOWN TO MINS OF 200 FT AGL + 1/2 MI VISIBILITY. THE PROBLEM BEGAN WHEN I TRIED TO TRANSITION FROM INST FLT TO NIGHT VFR WITH FOG. I NEVER GAINED ANY DEPTH PERCEPTION OR OUTSIDE REFS, AND THE RWY WAS WASHED OUT BY A MIXTURE OF THE FOG WITH THE RWY LIGHTS ON HIGH INTENSITY. WITHOUT ANY VISUAL REFS, I BEGAN TO DRIFT TO THE R OF THE CENTERLINE AT APPROX 150 FT AGL. THE CAPT SAID, 'MY ACFT' AND TOOK CTL OF THE ACFT. IN DOING SO, HE CORRECTED TO THE L BRINGING US TO THE L OF THE CENTERLINE. AFTER TOUCHDOWN, OUR L MAIN GEAR LEFT THE RWY STRIKING 2 RWY LIGHTS. HE WAS ABLE TO LAND NORMALLY AND BRING THE ACFT BACK TO THE CENTER OF THE RWY WITH LITTLE EFFORT. THE CONTRIBUTING FACTORS IN THIS SITUATION WERE: LATE NIGHT FLT, FOG, LOW CEILING, HIGH INTENSITY LIGHTS COMBINED WITH FOG, THE PLT UNABLE TO TRANSITION FROM NIGHT INST FLYING TO NIGHT VISUAL FLYING IN CLOSE PROX TO THE GND. IN ORDER TO PREVENT THIS FROM HAPPENING IN THE FUTURE, THE PLTS SHOULD BE TRAINED TO TRANSFER CTL OF THE ACFT TO THE PLT WHO HAS BEEN ADAPTED TO OUTSIDE REFS TO COMPLETE THE APCH WHEN THE WX IS DOWN TO MINS.
