A maintenance note was issued on nxxx to check the x-dim on all 3 gear within 10-25 cycles. The aircraft went back into service with '0' cycles flown. Every morning when I checked the MEL run there was zero cycles on the x-dim. With zero cycles; there was no need to check or schedule the aircraft for an x-dim check that day because it would be scheduled for a maximum of 11 cycles. The night shift usually updates the number of cycles flown that day and gives a number to start counting from the next day. I guess we missed the actual cycles flown.
Original NASA ASRS Text
Title: A MAINT CONTROLLER REPORTS THE REQUIRED X-DIMENSION (X-DIM) CHECK ON ALL THREE LANDING GEARS FOR A B737-300; WAS NOT ACCOMPLISHED WITHIN 10 TO 25 FLIGHT CYCLES.
Narrative: A MAINT NOTE WAS ISSUED ON NXXX TO CHK THE X-DIM ON ALL 3 GEAR WITHIN 10-25 CYCLES. THE ACFT WENT BACK INTO SVC WITH '0' CYCLES FLOWN. EVERY MORNING WHEN I CHKED THE MEL RUN THERE WAS ZERO CYCLES ON THE X-DIM. WITH ZERO CYCLES; THERE WAS NO NEED TO CHK OR SCHEDULE THE ACFT FOR AN X-DIM CHK THAT DAY BECAUSE IT WOULD BE SCHEDULED FOR A MAX OF 11 CYCLES. THE NIGHT SHIFT USUALLY UPDATES THE NUMBER OF CYCLES FLOWN THAT DAY AND GIVES A NUMBER TO START COUNTING FROM THE NEXT DAY. I GUESS WE MISSED THE ACTUAL CYCLES FLOWN.
