Narrative:

This aircraft was scheduled for routine maintenance to accomplish engine SOP; 150/200 hour inspections; a basic inspection; and a few pilot squawks. This was scheduled over a few days. The day before the flight I found a l-hand fuel drain leak that required quick defuel/xfer to empty left tank. This was accomplished and reseal parts were ordered priority due to several open schedule days. 24 hour scheduling was notified of the event and requested to 'block' out 2 more days to complete maintenance. The next day/morning; I was called to get notice from client scheduler that they had put a trip on the aircraft. I reminded them that I had requested the schedule block out days; but said I felt the fuel drain parts would/could get shipped differently to accomplish the task for the fuel drain leak. I called the parts to be counter-to-counter shipped for the evening and also called (local service center) to obtain the seals as well. I drove 4 hours to pick up service center parts and returned; installed late that pm. This is where I decided I didn't have enough time to accomplish the starter-generator spline inspections and logged them as done. I ran the aircraft the following day to leak check the oil change/SOP work on the engines. Day ended at XA00 in the morning. I came to work XG30 to prep and get the aircraft online at XI00. This next flight started poorly. During the XJ30 start; the #3 engine was reported 'hung start' by the crew. I quickly debriefed the crew. They reported 'only getting 12%...' I asked them to start again while I watched. This start was normal. I discuss with the crew to look with me at the electric/amp draw; time/duration of acceleration to evaluate the starter generator performance. As it was normal I ask them to stop engine and start again -- again normal. It was agreed to continue the trip. Next I went to the office and completed the paperwork and log entry.

Title: A FALCON 50 DURING A 150-200 HR MAINT CHK HAD THE #1 AND #3 ENGS STARTER DRIVE SPLINE INSPECTION SIGNED OFF AS COMPLETED THOUGH INSPECTION WAS NOT ACCOMPLISHED.

Narrative: THIS ACFT WAS SCHEDULED FOR ROUTINE MAINT TO ACCOMPLISH ENG SOP; 150/200 HR INSPECTIONS; A BASIC INSPECTION; AND A FEW PLT SQUAWKS. THIS WAS SCHEDULED OVER A FEW DAYS. THE DAY BEFORE THE FLT I FOUND A L-HAND FUEL DRAIN LEAK THAT REQUIRED QUICK DEFUEL/XFER TO EMPTY L TANK. THIS WAS ACCOMPLISHED AND RESEAL PARTS WERE ORDERED PRIORITY DUE TO SEVERAL OPEN SCHEDULE DAYS. 24 HR SCHEDULING WAS NOTIFIED OF THE EVENT AND REQUESTED TO 'BLOCK' OUT 2 MORE DAYS TO COMPLETE MAINT. THE NEXT DAY/MORNING; I WAS CALLED TO GET NOTICE FROM CLIENT SCHEDULER THAT THEY HAD PUT A TRIP ON THE ACFT. I REMINDED THEM THAT I HAD REQUESTED THE SCHEDULE BLOCK OUT DAYS; BUT SAID I FELT THE FUEL DRAIN PARTS WOULD/COULD GET SHIPPED DIFFERENTLY TO ACCOMPLISH THE TASK FOR THE FUEL DRAIN LEAK. I CALLED THE PARTS TO BE COUNTER-TO-COUNTER SHIPPED FOR THE EVENING AND ALSO CALLED (LCL SVC CTR) TO OBTAIN THE SEALS AS WELL. I DROVE 4 HRS TO PICK UP SVC CTR PARTS AND RETURNED; INSTALLED LATE THAT PM. THIS IS WHERE I DECIDED I DIDN'T HAVE ENOUGH TIME TO ACCOMPLISH THE STARTER-GENERATOR SPLINE INSPECTIONS AND LOGGED THEM AS DONE. I RAN THE ACFT THE FOLLOWING DAY TO LEAK CHK THE OIL CHANGE/SOP WORK ON THE ENGS. DAY ENDED AT XA00 IN THE MORNING. I CAME TO WORK XG30 TO PREP AND GET THE ACFT ONLINE AT XI00. THIS NEXT FLT STARTED POORLY. DURING THE XJ30 START; THE #3 ENG WAS RPTED 'HUNG START' BY THE CREW. I QUICKLY DEBRIEFED THE CREW. THEY RPTED 'ONLY GETTING 12%...' I ASKED THEM TO START AGAIN WHILE I WATCHED. THIS START WAS NORMAL. I DISCUSS WITH THE CREW TO LOOK WITH ME AT THE ELECTRIC/AMP DRAW; TIME/DURATION OF ACCELERATION TO EVAL THE STARTER GENERATOR PERFORMANCE. AS IT WAS NORMAL I ASK THEM TO STOP ENG AND START AGAIN -- AGAIN NORMAL. IT WAS AGREED TO CONTINUE THE TRIP. NEXT I WENT TO THE OFFICE AND COMPLETED THE PAPERWORK AND LOG ENTRY.
