Narrative:

Loss of separation on runway 33 at ads airport. The small cessna was part of a flight of 2 cessna's. He was aircraft #2. Flight leader aircraft #1 (X) informed tower they were a flight and that aircraft #2 (Y) had no radio or electrical. Later on, a learjet was sequenced behind the flight. Flight leader landed but controller forgot it was a flight of 2 and forgot about aircraft #2. Then the learjet (aircraft Z) landed and barely stopped before running into aircraft #2 from behind. Controller at fault but...special circumstances. Why is anyone flying a plane at night without lights. Review of radar tape shows aircraft #2 more than 1 mi behind aircraft #1. Aircraft #1 had landed, taxied off runway, talked to ground control and was taxiing to ramp...not taking care of the rest of his flight which was still landing. Since aircraft #2 had no electrical, therefore, no transponder, the d-brite scope rarely displays a target.

Title: ATCT LCL CTLR FORGOT ABOUT NUMBER 2 OF A FLT OF 2 CESSNA'S, LNDG A LR55 WHEN THE SECOND CESSNA HAD NOT YET CLRED THE RWY. LR55 HAD TO TAKE EVASIVE ACTIONS NOT TO HIT THE CESSNA ON THE RWY.

Narrative: LOSS OF SEPARATION ON RWY 33 AT ADS ARPT. THE SMALL CESSNA WAS PART OF A FLT OF 2 CESSNA'S. HE WAS ACFT #2. FLT LEADER ACFT #1 (X) INFORMED TWR THEY WERE A FLT AND THAT ACFT #2 (Y) HAD NO RADIO OR ELECTRICAL. LATER ON, A LEARJET WAS SEQUENCED BEHIND THE FLT. FLT LEADER LANDED BUT CTLR FORGOT IT WAS A FLT OF 2 AND FORGOT ABOUT ACFT #2. THEN THE LEARJET (ACFT Z) LANDED AND BARELY STOPPED BEFORE RUNNING INTO ACFT #2 FROM BEHIND. CTLR AT FAULT BUT...SPECIAL CIRCUMSTANCES. WHY IS ANYONE FLYING A PLANE AT NIGHT WITHOUT LIGHTS. REVIEW OF RADAR TAPE SHOWS ACFT #2 MORE THAN 1 MI BEHIND ACFT #1. ACFT #1 HAD LANDED, TAXIED OFF RWY, TALKED TO GND CTL AND WAS TAXIING TO RAMP...NOT TAKING CARE OF THE REST OF HIS FLT WHICH WAS STILL LNDG. SINCE ACFT #2 HAD NO ELECTRICAL, THEREFORE, NO XPONDER, THE D-BRITE SCOPE RARELY DISPLAYS A TARGET.
