We received a request from hospital to pick up and transport a child from ZZZ to hospital. The off going flight crew was returning from a flight and still about 20 minutes out. As soon as they landed, the flight nurses quickly restocked the medical equipment while I refueled and did a quick check of the aircraft. While I was doing this the previous pilot informed me that we may be at the 33 hour inspection. I took a quick look at the flight logs, added the times in my head and figured that we were just short of the inspection. Since our aaip allows us to overfly the 33 hour inspection by 3 hours, my flight plan was for only 2 hours, and I had already informed the doctor that we could make the flight, I went ahead and departed. While I was waiting for the nurses to return to the aircraft, I took the time to check the logs more closely and realized that I had misread one of the numbers and instead of being just short of the 33 hour inspection it was in fact 0.4 hours over when I had departed. I immediately contacted the director of maintenance, informed him of my estimated time of arrival back at our base, and advised him that I would take the aircraft OTS so that he could complete the inspection, as required. My flight took 2.1 hours and the 33 hour inspection was completed at 35.5 hours.

Title: REPORTER MISCALCULATES ACFT INSPECTION TIMES.
Narrative: WE RECEIVED A REQUEST FROM HOSPITAL TO PICK UP AND TRANSPORT A CHILD FROM ZZZ TO HOSPITAL. THE OFF GOING FLT CREW WAS RETURNING FROM A FLT AND STILL ABOUT 20 MINUTES OUT. AS SOON AS THEY LANDED, THE FLT NURSES QUICKLY RESTOCKED THE MEDICAL EQUIP WHILE I REFUELED AND DID A QUICK CHECK OF THE ACFT. WHILE I WAS DOING THIS THE PREVIOUS PLT INFORMED ME THAT WE MAY BE AT THE 33 HR INSPECTION. I TOOK A QUICK LOOK AT THE FLT LOGS, ADDED THE TIMES IN MY HEAD AND FIGURED THAT WE WERE JUST SHORT OF THE INSPECTION. SINCE OUR AAIP ALLOWS US TO OVERFLY THE 33 HR INSPECTION BY 3 HRS, MY FLT PLAN WAS FOR ONLY 2 HRS, AND I HAD ALREADY INFORMED THE DOCTOR THAT WE COULD MAKE THE FLT, I WENT AHEAD AND DEPARTED. WHILE I WAS WAITING FOR THE NURSES TO RETURN TO THE ACFT, I TOOK THE TIME TO CHECK THE LOGS MORE CLOSELY AND REALIZED THAT I HAD MISREAD ONE OF THE NUMBERS AND INSTEAD OF BEING JUST SHORT OF THE 33 HR INSPECTION IT WAS IN FACT 0.4 HRS OVER WHEN I HAD DEPARTED. I IMMEDIATELY CONTACTED THE DIRECTOR OF MAINT, INFORMED HIM OF MY ESTIMATED TIME OF ARR BACK AT OUR BASE, AND ADVISED HIM THAT I WOULD TAKE THE ACFT OTS SO THAT HE COULD COMPLETE THE INSPECTION, AS REQUIRED. MY FLT TOOK 2.1 HRS AND THE 33 HR INSPECTION WAS COMPLETED AT 35.5 HRS.
