Narrative:

I landed at destin ft walton beach airport at approximately XY00 pm local time. I parked the lear 24 as directed by the FBO/unicom operator. The learjet was parked by me well clear of all aircraft and there were no aircraft parked immediately either side of me. I was parked at the end of a line of aircraft. My aircraft was then fueled by the FBO operator. Approximately 30 mins after landing, I notified the FBO line crewman that I wanted to depart and that I needed a ground power unit for starting of my engines. The line crew man plugged a gpu into my aircraft. I then boarded the learjet with my copilot and after shutting the doors, proceeded with the starting of the engines. The FBO's line crewman unplugged the gpu at my command and then he walked back in front of my aircraft and directed me to taxi out of my parking spot and then directed me to make an almost immediate right to turn onto a taxiway line that was perpendicular to my position. After turning to the right, the unicom operator and an employee on the ground signalled for me to stop and shut down the engines, which I did. Sometime between the time I first parked and then started to taxi for departure, the FBO/operator had parked a cessna 150 to the left of my learjet. The FBO/operator neglected to tie down the wings of the cessna 150. After departing my aircraft, the FBO operator told me that my exhaust blast had caused the cessna 150 to tip to the left and that the cessna 150's left wing tip had touched the ground. The cessna 150 was in a normal position when I viewed it and there were no passenger on board during the occurrence. I used normal starting procedures and started and continued my taxi in a normal way. The FBO/operator should have tied down the wings of the cessna 150 or parked it someplace else or towed my aircraft to a different spot on the airport.

Title: LEAR-24 JET BLASTS A C-150 OVER ON IT'S WINGTIP DURING RAMP OP RAMP DEP PROC.

Narrative: I LANDED AT DESTIN FT WALTON BEACH ARPT AT APPROX XY00 PM LCL TIME. I PARKED THE LEAR 24 AS DIRECTED BY THE FBO/UNICOM OPERATOR. THE LEARJET WAS PARKED BY ME WELL CLR OF ALL ACFT AND THERE WERE NO ACFT PARKED IMMEDIATELY EITHER SIDE OF ME. I WAS PARKED AT THE END OF A LINE OF ACFT. MY ACFT WAS THEN FUELED BY THE FBO OPERATOR. APPROX 30 MINS AFTER LNDG, I NOTIFIED THE FBO LINE CREWMAN THAT I WANTED TO DEPART AND THAT I NEEDED A GND PWR UNIT FOR STARTING OF MY ENGS. THE LINE CREW MAN PLUGGED A GPU INTO MY ACFT. I THEN BOARDED THE LEARJET WITH MY COPLT AND AFTER SHUTTING THE DOORS, PROCEEDED WITH THE STARTING OF THE ENGS. THE FBO'S LINE CREWMAN UNPLUGGED THE GPU AT MY COMMAND AND THEN HE WALKED BACK IN FRONT OF MY ACFT AND DIRECTED ME TO TAXI OUT OF MY PARKING SPOT AND THEN DIRECTED ME TO MAKE AN ALMOST IMMEDIATE R TO TURN ONTO A TXWY LINE THAT WAS PERPENDICULAR TO MY POS. AFTER TURNING TO THE R, THE UNICOM OPERATOR AND AN EMPLOYEE ON THE GND SIGNALLED FOR ME TO STOP AND SHUT DOWN THE ENGS, WHICH I DID. SOMETIME BTWN THE TIME I FIRST PARKED AND THEN STARTED TO TAXI FOR DEP, THE FBO/OPERATOR HAD PARKED A CESSNA 150 TO THE L OF MY LEARJET. THE FBO/OPERATOR NEGLECTED TO TIE DOWN THE WINGS OF THE CESSNA 150. AFTER DEPARTING MY ACFT, THE FBO OPERATOR TOLD ME THAT MY EXHAUST BLAST HAD CAUSED THE CESSNA 150 TO TIP TO THE L AND THAT THE CESSNA 150'S L WING TIP HAD TOUCHED THE GND. THE CESSNA 150 WAS IN A NORMAL POS WHEN I VIEWED IT AND THERE WERE NO PAX ON BOARD DURING THE OCCURRENCE. I USED NORMAL STARTING PROCS AND STARTED AND CONTINUED MY TAXI IN A NORMAL WAY. THE FBO/OPERATOR SHOULD HAVE TIED DOWN THE WINGS OF THE CESSNA 150 OR PARKED IT SOMEPLACE ELSE OR TOWED MY ACFT TO A DIFFERENT SPOT ON THE ARPT.
