Narrative:

After an uneventful flight from fxe in florida to mdsd we were instructed and guided to park by the airport security office. We stopped about 15 yards from the curb of a sidewalk, nose in. Close by, maybe 60-70 yards away there were 2 jet acrs also parked nose in, one of them a B727 was getting ready for departure. After shutdown I applied the parking brake since nobody could find a set of chocks around. We were approached by about 6 or 7 people from the different organizations (customs, security, immigration, etc) asking all kinds of questions and demanding paperwork. Shortly after deplaning and unloading the baggage we were instructed to follow them inside to the security office and then customs and immigration and so on. A few mins after, about 25 mins after parking the airplane, one of the security officers came to us to let us know that the airplane (a learjet 35) had rolled forward onto the building. This was due to the fact that the air carrier B727 was pushed back for taxi out, and since there is an upslope from the flat ramp to the main taxiway, the amount of power used was considerable (so as to break the inertia). Some of this jet blast reached our airplane and it was pushed forward and started rolling. Unknown to me, the brakes (parking brake) had been released, either by accident or it bled down. This I was not able to determine. Consequently the airplane rolled forward until hitting the sidewalk curb, this made the airplane stop but the right wingtip tank tip broke through one of the office glass panes. Fortunately, the only damage to the airplane was a broken recognition light lens on the tip of the tip tank and some scratches due to the falling glass around the tip tank. There was no other damage to the building except a broken glass pane. I believe this occurrence could have been prevented if we had not been pressured into rushing out of the airplane to leave the area. Having more time to do things I would have found something that could have been used as a chock.

Title: A CPR LR35 FLC PARKS WITHOUT CHOCKING THE MAIN GEAR AND SUBSEQUENTLY THE ACFT IS HIT BY JET BLAST AND ROLLS INTO A BUILDING SUFFERING MINOR DAMAGE AND BREAKING A WINDOW IN THE BUILDING. THE FLC BLAME THE ARPT OFFICIALS FOR RUSHING THEM.

Narrative: AFTER AN UNEVENTFUL FLT FROM FXE IN FLORIDA TO MDSD WE WERE INSTRUCTED AND GUIDED TO PARK BY THE ARPT SECURITY OFFICE. WE STOPPED ABOUT 15 YARDS FROM THE CURB OF A SIDEWALK, NOSE IN. CLOSE BY, MAYBE 60-70 YARDS AWAY THERE WERE 2 JET ACRS ALSO PARKED NOSE IN, ONE OF THEM A B727 WAS GETTING READY FOR DEP. AFTER SHUTDOWN I APPLIED THE PARKING BRAKE SINCE NOBODY COULD FIND A SET OF CHOCKS AROUND. WE WERE APCHED BY ABOUT 6 OR 7 PEOPLE FROM THE DIFFERENT ORGANIZATIONS (CUSTOMS, SECURITY, IMMIGRATION, ETC) ASKING ALL KINDS OF QUESTIONS AND DEMANDING PAPERWORK. SHORTLY AFTER DEPLANING AND UNLOADING THE BAGGAGE WE WERE INSTRUCTED TO FOLLOW THEM INSIDE TO THE SECURITY OFFICE AND THEN CUSTOMS AND IMMIGRATION AND SO ON. A FEW MINS AFTER, ABOUT 25 MINS AFTER PARKING THE AIRPLANE, ONE OF THE SECURITY OFFICERS CAME TO US TO LET US KNOW THAT THE AIRPLANE (A LEARJET 35) HAD ROLLED FORWARD ONTO THE BUILDING. THIS WAS DUE TO THE FACT THAT THE ACR B727 WAS PUSHED BACK FOR TAXI OUT, AND SINCE THERE IS AN UPSLOPE FROM THE FLAT RAMP TO THE MAIN TXWY, THE AMOUNT OF PWR USED WAS CONSIDERABLE (SO AS TO BREAK THE INERTIA). SOME OF THIS JET BLAST REACHED OUR AIRPLANE AND IT WAS PUSHED FORWARD AND STARTED ROLLING. UNKNOWN TO ME, THE BRAKES (PARKING BRAKE) HAD BEEN RELEASED, EITHER BY ACCIDENT OR IT BLED DOWN. THIS I WAS NOT ABLE TO DETERMINE. CONSEQUENTLY THE AIRPLANE ROLLED FORWARD UNTIL HITTING THE SIDEWALK CURB, THIS MADE THE AIRPLANE STOP BUT THE RIGHT WINGTIP TANK TIP BROKE THROUGH ONE OF THE OFFICE GLASS PANES. FORTUNATELY, THE ONLY DAMAGE TO THE AIRPLANE WAS A BROKEN RECOGNITION LIGHT LENS ON THE TIP OF THE TIP TANK AND SOME SCRATCHES DUE TO THE FALLING GLASS AROUND THE TIP TANK. THERE WAS NO OTHER DAMAGE TO THE BUILDING EXCEPT A BROKEN GLASS PANE. I BELIEVE THIS OCCURRENCE COULD HAVE BEEN PREVENTED IF WE HAD NOT BEEN PRESSURED INTO RUSHING OUT OF THE AIRPLANE TO LEAVE THE AREA. HAVING MORE TIME TO DO THINGS I WOULD HAVE FOUND SOMETHING THAT COULD HAVE BEEN USED AS A CHOCK.
