Narrative:

After landing on runway 31L at bfi, we cleared at taxiway A4. Tower directed us to cross runway 31R, join taxiway a and contact ground. Ground acknowledged our call and told us to taxi to parking. This was our last communication with ATC. Approaching taxiway A8, we observed 2 light aircraft in the run-up area for runway 31R. The captain maneuvered the aircraft to the left (as much as the biz-jets parked east of the taxiway would allow) to ensure adequate clearance with the 2 light aircraft. As we approached the aircraft, one of them taxied onto runway 31R, presumably for takeoff. After we passed the remaining aircraft, the captain steered back to the center of the taxiway. We observed our marshaller approximately 100 yards beyond taxiway A8. At this time, my attention was directed toward our parking area. A DC8 was parked in the spot next to ours, perpendicular to the taxiway, and several ramp loaders were between that aircraft and our parking spot. Our parking spot was situated such that we would have to make an approximately 135 degree turn away from the runways into our ramp area. The marshaller initially had us make a turn of 45-60 degrees, then turn in the rest of the way in order to align the fuselage with the parking spot. After we had parked the aircraft and shut down, a mechanic boarded the aircraft and informed us that a C150 had been upset by our jet exhaust. Based on statements made by witnesses on the ground, the right wing of the cessna lifted up, causing the left wingtip to strike the ground, then the tail was lifted up, causing the propeller to strike the ground and the engine to stop. The aircraft then came to rest on its landing gear. No one was injured. Supplemental information from acn 473662: ground speed was 3 KTS with enough power to maintain forward progress for approximately 130 degrees left turn. Very limited room and we did have wing walkers. We were given no indications from the marshallers, wing walkers, or ground control that there was any problem.

Title: A B767-200 CARGO ACFT BLOWS A HOLDING C150 UP ON ITS NOSE AND WINGTIP WHILE TURNING INTO THE PARKING AREA 100-200 YARDS FROM THE RUN-UP PAD FOR RWY 31R AT BFI, WA.

Narrative: AFTER LNDG ON RWY 31L AT BFI, WE CLRED AT TXWY A4. TWR DIRECTED US TO CROSS RWY 31R, JOIN TXWY A AND CONTACT GND. GND ACKNOWLEDGED OUR CALL AND TOLD US TO TAXI TO PARKING. THIS WAS OUR LAST COM WITH ATC. APCHING TXWY A8, WE OBSERVED 2 LIGHT ACFT IN THE RUN-UP AREA FOR RWY 31R. THE CAPT MANEUVERED THE ACFT TO THE L (AS MUCH AS THE BIZ-JETS PARKED E OF THE TXWY WOULD ALLOW) TO ENSURE ADEQUATE CLRNC WITH THE 2 LIGHT ACFT. AS WE APCHED THE ACFT, ONE OF THEM TAXIED ONTO RWY 31R, PRESUMABLY FOR TKOF. AFTER WE PASSED THE REMAINING ACFT, THE CAPT STEERED BACK TO THE CTR OF THE TXWY. WE OBSERVED OUR MARSHALLER APPROX 100 YARDS BEYOND TXWY A8. AT THIS TIME, MY ATTN WAS DIRECTED TOWARD OUR PARKING AREA. A DC8 WAS PARKED IN THE SPOT NEXT TO OURS, PERPENDICULAR TO THE TXWY, AND SEVERAL RAMP LOADERS WERE BTWN THAT ACFT AND OUR PARKING SPOT. OUR PARKING SPOT WAS SITUATED SUCH THAT WE WOULD HAVE TO MAKE AN APPROX 135 DEG TURN AWAY FROM THE RWYS INTO OUR RAMP AREA. THE MARSHALLER INITIALLY HAD US MAKE A TURN OF 45-60 DEGS, THEN TURN IN THE REST OF THE WAY IN ORDER TO ALIGN THE FUSELAGE WITH THE PARKING SPOT. AFTER WE HAD PARKED THE ACFT AND SHUT DOWN, A MECH BOARDED THE ACFT AND INFORMED US THAT A C150 HAD BEEN UPSET BY OUR JET EXHAUST. BASED ON STATEMENTS MADE BY WITNESSES ON THE GND, THE R WING OF THE CESSNA LIFTED UP, CAUSING THE L WINGTIP TO STRIKE THE GND, THEN THE TAIL WAS LIFTED UP, CAUSING THE PROP TO STRIKE THE GND AND THE ENG TO STOP. THE ACFT THEN CAME TO REST ON ITS LNDG GEAR. NO ONE WAS INJURED. SUPPLEMENTAL INFO FROM ACN 473662: GND SPD WAS 3 KTS WITH ENOUGH PWR TO MAINTAIN FORWARD PROGRESS FOR APPROX 130 DEGS L TURN. VERY LIMITED ROOM AND WE DID HAVE WING WALKERS. WE WERE GIVEN NO INDICATIONS FROM THE MARSHALLERS, WING WALKERS, OR GND CTL THAT THERE WAS ANY PROB.
