Narrative:

After several unsuccessful attempts, flight dispatch contacted maintenance control. I was working the B727/A320 desk but assisted in helping out my fellow controller who was busy on another call. It was a flight that was off the block in XXX. The flight crew indicated that upon #1 engine start, the generator had not come on-line and showed no frequencys, volts, oil pressure or temperature. After requesting the crew to verify all circuit breakers were in, including the circuit breaker on the gcu, with the captain's and dispatcher's concurrence, all were in agreement to continue on with the #1 generator inoperative. Hence I authority/authorized deferral with the #1 generator inoperative per MEL. What I didn't do was review the requirements for the MEL, which required that the CSD and APU oil level to be checked. By the time I realized my error, the flight was in the air. The flight landed without incident and maintenance in ZZZ reset the CSD and checked the oil, and subsequent engine run verified that the generator was operable.

Title: A B737-200 WAS DISPATCHED IN NON COMPLIANCE WITH #1 GENERATOR DEFERRED INOP, PER THE MEL, BUT A CHK OF THE CSD OIL LEVEL WAS NOT ACCOMPLISHED.

Narrative: AFTER SEVERAL UNSUCCESSFUL ATTEMPTS, FLT DISPATCH CONTACTED MAINT CTL. I WAS WORKING THE B727/A320 DESK BUT ASSISTED IN HELPING OUT MY FELLOW CTLR WHO WAS BUSY ON ANOTHER CALL. IT WAS A FLT THAT WAS OFF THE BLOCK IN XXX. THE FLC INDICATED THAT UPON #1 ENG START, THE GENERATOR HAD NOT COME ON-LINE AND SHOWED NO FREQS, VOLTS, OIL PRESSURE OR TEMP. AFTER REQUESTING THE CREW TO VERIFY ALL CIRCUIT BREAKERS WERE IN, INCLUDING THE CIRCUIT BREAKER ON THE GCU, WITH THE CAPT'S AND DISPATCHER'S CONCURRENCE, ALL WERE IN AGREEMENT TO CONTINUE ON WITH THE #1 GENERATOR INOP. HENCE I AUTH DEFERRAL WITH THE #1 GENERATOR INOP PER MEL. WHAT I DIDN'T DO WAS REVIEW THE REQUIREMENTS FOR THE MEL, WHICH REQUIRED THAT THE CSD AND APU OIL LEVEL TO BE CHKED. BY THE TIME I REALIZED MY ERROR, THE FLT WAS IN THE AIR. THE FLT LANDED WITHOUT INCIDENT AND MAINT IN ZZZ RESET THE CSD AND CHKED THE OIL, AND SUBSEQUENT ENG RUN VERIFIED THAT THE GENERATOR WAS OPERABLE.
