A C560 CITATION FLC IS STRANDED IN OAK; CA; WHEN THEIR MAINT DEPT FINDS THAT THEIR ACFT IS OVERDUE FOR A CRITICAL INSPECTION WHILE ACFT IS AWAY FROM HOME BASE AT ZZZ; US.

Narrative

IN OMA THE CREW PERFORMED A REQUIRED PREFLT INSPECTION AND PREPARATIONS FOR THE DAY'S ASSIGNMENT OF OMA-ASE-OAK-SJC-UUD. AS ONE OF MANY PARTS OF THE PREFLT PROC; THE CREW COMPARED THE ACFT LOGBOOK TIMES WITH THE CURRENT MAINT STATUS SHEET ISSUED. NO INSPECTIONS WERE REQUIRED AND ALL OTHER PREFLT OPS WERE OK. THE CREW FLEW THE SCHEDULE; OMA-ASE-OAK; UNTIL FLT SUPPORT TOLD US TO NOT MOVE THE ACFT TO SJC UNTIL FURTHER NOTICE. THE CREW WAS LATER ADVISED THAT A MAINT INSPECTION OF ACFT Y WAS NOT COMPLETED AT THE REQUIRED HRLY INSPECTION TIME. MAINT AND OPS SELF-DISCLOSED THIS INFO TO THE LCL FAA. MAINT TRIED TO APPLY FOR A FERRY PERMIT TO FLY THE ACFT TO ITS HOME BASE. THIS WAS DENIED BY THE FAA. BY THIS TIME; THE CREW'S DUTY DAY WAS EXHAUSTED AND WERE GIVEN A REST PERIOD. THE NEXT DAY THIS CREW AIRLINED TO OUR HOME. THE ACFT REMAINED IN OAK; CA. THE CREW HAD NO IDEA AN INSPECTION WAS MISSED BY MAINT DEPT. AS PER THE CURRENT ACFT MAINT STATUS SHEET; THE ACFT WAS LEGAL. CORRECTIVE ACTIONS: A BETTER SYS TO KEEP TRACK OF INSPECTION PERIODS. EITHER COMPUTERIZED OR HAVE 2 DEPTS WATCHING THE ACFT TIMES AND RPTING TO EACH OTHER WHEN AN INSPECTION IS NEAR. A CORRECT MAINT STATUS SHEET SHOULD BE IN THE ACFT OR PROVIDED TO THE CREW ON A WKLY BASIS BY FAX. THIS IS A THIRD WAY TO CATCH A MISTAKE PRIOR TO BECOMING A PROB.
