Narrative:

I fly as an first officer in a lear 35A. During the daytime our primary lear is pre-positioned for a flight on the FBO service ramp. The line service people are in charge of positioning all the aircraft on their ramp. Our learjet was positioned in the normal spot next to the door on the south end of the hangar. The plane was pointing south. There were some other planes parked in a line at the north end of the hangar. Just to clarify, I am writing about planes parked in front of the hangar on the ramp area. It was a very hot day, at least 90 degrees. The power cord for the helicopters passed in front of the wheels of our lear, but this was nothing unusual. There was a falcon jet parked right in front of us receiving maintenance. It was my leg so I was the PF. I informed the captain that I would just start the right engine and taxi on 1 engine up to the taxiway so as not to jet blast the guy working on the falcon in front of us when we made the right turn to the taxiway. We went through the checklists and I started the right engine. I advanced the throttle approximately 2/3 of the way and the wheels would not budge. I decided to start the other engine. The captain concurred. We started the left engine and taxied out for an uneventful flight. When we got back our mechanic informed us that when we taxied out, our jet wash damaged a piston cessna that was parked behind us with the tail pointing at us. It caught the tail and spun the cessna (looked like a C182) around. The leading edge of the right wing of the cessna was damaged. No one actually saw what happened, but this is everybody's best guess. The cessna was not tied down and FBO is not supposed to park small planes with their tails facing us. This incident could have been avoided if FBO did not park their planes behind us, and we could have avoided it if we had recognized the potential danger and had FBO tow us out to the taxiway for a battery start. Supplemental information from acn 589814: this damage could have been avoided by closer observation of aircraft environment prior to taxi. The situation seemed to be a familiar one. I dealt with the power cord and other aircraft parked close on a daily basis, but I failed to notice 2 variations: one, the cord was, in the past, always crossed with a running start and two, the aircraft parked behind us were tail to our tail instead of nose to our tail as agreed with FBO.

Title: A DEP LEAR JET DAMAGES A C182 WITH ITS JET BLAST WHEN DEPARTING THE RAMP.

Narrative: I FLY AS AN FO IN A LEAR 35A. DURING THE DAYTIME OUR PRIMARY LEAR IS PRE-POSITIONED FOR A FLT ON THE FBO SVC RAMP. THE LINE SVC PEOPLE ARE IN CHARGE OF POSITIONING ALL THE ACFT ON THEIR RAMP. OUR LEARJET WAS POSITIONED IN THE NORMAL SPOT NEXT TO THE DOOR ON THE S END OF THE HANGAR. THE PLANE WAS POINTING S. THERE WERE SOME OTHER PLANES PARKED IN A LINE AT THE N END OF THE HANGAR. JUST TO CLARIFY, I AM WRITING ABOUT PLANES PARKED IN FRONT OF THE HANGAR ON THE RAMP AREA. IT WAS A VERY HOT DAY, AT LEAST 90 DEGS. THE PWR CORD FOR THE HELIS PASSED IN FRONT OF THE WHEELS OF OUR LEAR, BUT THIS WAS NOTHING UNUSUAL. THERE WAS A FALCON JET PARKED RIGHT IN FRONT OF US RECEIVING MAINT. IT WAS MY LEG SO I WAS THE PF. I INFORMED THE CAPT THAT I WOULD JUST START THE R ENG AND TAXI ON 1 ENG UP TO THE TXWY SO AS NOT TO JET BLAST THE GUY WORKING ON THE FALCON IN FRONT OF US WHEN WE MADE THE R TURN TO THE TXWY. WE WENT THROUGH THE CHKLISTS AND I STARTED THE R ENG. I ADVANCED THE THROTTLE APPROX 2/3 OF THE WAY AND THE WHEELS WOULD NOT BUDGE. I DECIDED TO START THE OTHER ENG. THE CAPT CONCURRED. WE STARTED THE L ENG AND TAXIED OUT FOR AN UNEVENTFUL FLT. WHEN WE GOT BACK OUR MECH INFORMED US THAT WHEN WE TAXIED OUT, OUR JET WASH DAMAGED A PISTON CESSNA THAT WAS PARKED BEHIND US WITH THE TAIL POINTING AT US. IT CAUGHT THE TAIL AND SPUN THE CESSNA (LOOKED LIKE A C182) AROUND. THE LEADING EDGE OF THE R WING OF THE CESSNA WAS DAMAGED. NO ONE ACTUALLY SAW WHAT HAPPENED, BUT THIS IS EVERYBODY'S BEST GUESS. THE CESSNA WAS NOT TIED DOWN AND FBO IS NOT SUPPOSED TO PARK SMALL PLANES WITH THEIR TAILS FACING US. THIS INCIDENT COULD HAVE BEEN AVOIDED IF FBO DID NOT PARK THEIR PLANES BEHIND US, AND WE COULD HAVE AVOIDED IT IF WE HAD RECOGNIZED THE POTENTIAL DANGER AND HAD FBO TOW US OUT TO THE TXWY FOR A BATTERY START. SUPPLEMENTAL INFO FROM ACN 589814: THIS DAMAGE COULD HAVE BEEN AVOIDED BY CLOSER OBSERVATION OF ACFT ENVIRONMENT PRIOR TO TAXI. THE SIT SEEMED TO BE A FAMILIAR ONE. I DEALT WITH THE PWR CORD AND OTHER ACFT PARKED CLOSE ON A DAILY BASIS, BUT I FAILED TO NOTICE 2 VARIATIONS: ONE, THE CORD WAS, IN THE PAST, ALWAYS CROSSED WITH A RUNNING START AND TWO, THE ACFT PARKED BEHIND US WERE TAIL TO OUR TAIL INSTEAD OF NOSE TO OUR TAIL AS AGREED WITH FBO.
