Narrative:

On preflight before an far part 135 air taxi flight, the 100 hour inspection was noted due at .4248 hours per the status sheet. The aircraft can be flown an additional 5 hours past this time (per company manual). The starting hour recording meter time for the aircraft was 4248.Z hours. The air taxi flight that I was to fly would be roughly 2.5 hours. The trip was flown and completed without trouble. Upon our return the aircraft maintenance logs were consulted and the 100 hour inspection noted due at 4243 hours not 4248 hours as noted on the status sheet. The trip I flew was not in compliance with part 135 FARS. I flew the aircraft 2.5 hours beyond the 100 hour inspection. The status sheets are kept up by the department head (also an air taxi pilot), and the aircraft time he put on the status was incorrect. My opinion is that our department head has too much work at times and sometimes becomes distracted from his work. He said better attention would be paid to status sheets of our company aircraft.

Title: PLT OF FEDERAL AVIATION REG PART 135 FLT RULES RELIES ON COMPANY STATUS SHEET, AND DOES NOT CHECK ACFT LOGBOOKS TO ENSURE THAT THE ACFT WILL BE OPERATED WITHIN THE 100 HOUR MAINTENANCE INSPECTION REQUIREMENT.

Narrative: ON PREFLT BEFORE AN FAR PART 135 AIR TAXI FLT, THE 100 HR INSPECTION WAS NOTED DUE AT .4248 HOURS PER THE STATUS SHEET. THE ACFT CAN BE FLOWN AN ADDITIONAL 5 HRS PAST THIS TIME (PER COMPANY MANUAL). THE STARTING HOUR RECORDING METER TIME FOR THE ACFT WAS 4248.Z HOURS. THE AIR TAXI FLT THAT I WAS TO FLY WOULD BE ROUGHLY 2.5 HRS. THE TRIP WAS FLOWN AND COMPLETED WITHOUT TROUBLE. UPON OUR RETURN THE ACFT MAINT LOGS WERE CONSULTED AND THE 100 HOUR INSPECTION NOTED DUE AT 4243 HOURS NOT 4248 HOURS AS NOTED ON THE STATUS SHEET. THE TRIP I FLEW WAS NOT IN COMPLIANCE WITH PART 135 FARS. I FLEW THE ACFT 2.5 HRS BEYOND THE 100 HR INSPECTION. THE STATUS SHEETS ARE KEPT UP BY THE DEPT HEAD (ALSO AN AIR TAXI PLT), AND THE ACFT TIME HE PUT ON THE STATUS WAS INCORRECT. MY OPINION IS THAT OUR DEPT HEAD HAS TOO MUCH WORK AT TIMES AND SOMETIMES BECOMES DISTRACTED FROM HIS WORK. HE SAID BETTER ATTN WOULD BE PAID TO STATUS SHEETS OF OUR COMPANY ACFT.
