Narrative:

I was conducting a part 135 flight from ZZZ to las. The flight began at XA48 when I began taxiing the aircraft. I was parked in the far west corner of the ramp (in front of FBO X and right next to the taxiway that runs along the northwest edge of the ramp). I needed to immediately complete a 180 degree r-hand turn to begin moving toward the runway for departure. While conducting the turn; I noticed that the turn was wider than expected (the aircraft did not turn easily even though I had full right brake and rudder pedal pressure applied and high left engine RPM); which resulted in the aircraft lining up left of the yellow taxiway as the wing tip approached the corner of the hangar located on the left side of the taxiway (northwest side of the ramp); I observed the close proximity of the wingtip to the hangar; and judged that I would have enough clearance to continue the turn and to taxi. After the wingtip traveled parallel to the hangar wall for 3 - 3 1/2 ft; the tip struck the hangar wall; causing damage to the wingtip and the steel panels on the hangar wall. I continued the turn to park back in the spot that I taxied out of; shut down the engines; and de-boarded the aircraft. The result was physical damage to the plexiglas cover around the lights on the wingtip; damage to the sheet metal cap on the wingtip; and damage to the fiberglas cap on the aileron. Damage also occurred on the steel panels of the hangar wall (holes were ripped into the ridges; and the paneling was ripped back at 3 locations). I believe this situation could have been avoided by some simple actions. First; after the aircraft was towed to the new parking location by line service; I should have taken the time to become more familiar with the taxi area and the exit rtes prior to boarding the aircraft. When I taxied into the airport; I originally parked the aircraft near the center of the ramp. Line service then towed the aircraft closer to the FBO; and into the corner of the ramp. This was my first flight into ZZZ; and I should have reviewed the area prior to taxi; not assumed that just because there are taxi lines painted; then adequate clearance is provided. I should have looked for alternate taxi rtes; rather than just turn to the closest taxiway. Also; I will give myself more of a cushion on spacing when determining wing clearance. If I had not accepted the minimal clearance prior to the tip passing the corner of the hangar; I could have shut down the engines and had line service tow the aircraft to a more desirable location/position on the ramp.

Title: BE20 FLT CREW TAXI ACFT WING INTO HANGAR IN CONFINED TAXI SPACE CAUSING DAMAGE.

Narrative: I WAS CONDUCTING A PART 135 FLT FROM ZZZ TO LAS. THE FLT BEGAN AT XA48 WHEN I BEGAN TAXIING THE ACFT. I WAS PARKED IN THE FAR W CORNER OF THE RAMP (IN FRONT OF FBO X AND RIGHT NEXT TO THE TXWY THAT RUNS ALONG THE NW EDGE OF THE RAMP). I NEEDED TO IMMEDIATELY COMPLETE A 180 DEG R-HAND TURN TO BEGIN MOVING TOWARD THE RWY FOR DEP. WHILE CONDUCTING THE TURN; I NOTICED THAT THE TURN WAS WIDER THAN EXPECTED (THE ACFT DID NOT TURN EASILY EVEN THOUGH I HAD FULL R BRAKE AND RUDDER PEDAL PRESSURE APPLIED AND HIGH L ENG RPM); WHICH RESULTED IN THE ACFT LINING UP L OF THE YELLOW TXWY AS THE WING TIP APPROACHED THE CORNER OF THE HANGAR LOCATED ON THE L SIDE OF THE TXWY (NW SIDE OF THE RAMP); I OBSERVED THE CLOSE PROX OF THE WINGTIP TO THE HANGAR; AND JUDGED THAT I WOULD HAVE ENOUGH CLRNC TO CONTINUE THE TURN AND TO TAXI. AFTER THE WINGTIP TRAVELED PARALLEL TO THE HANGAR WALL FOR 3 - 3 1/2 FT; THE TIP STRUCK THE HANGAR WALL; CAUSING DAMAGE TO THE WINGTIP AND THE STEEL PANELS ON THE HANGAR WALL. I CONTINUED THE TURN TO PARK BACK IN THE SPOT THAT I TAXIED OUT OF; SHUT DOWN THE ENGS; AND DE-BOARDED THE ACFT. THE RESULT WAS PHYSICAL DAMAGE TO THE PLEXIGLAS COVER AROUND THE LIGHTS ON THE WINGTIP; DAMAGE TO THE SHEET METAL CAP ON THE WINGTIP; AND DAMAGE TO THE FIBERGLAS CAP ON THE AILERON. DAMAGE ALSO OCCURRED ON THE STEEL PANELS OF THE HANGAR WALL (HOLES WERE RIPPED INTO THE RIDGES; AND THE PANELING WAS RIPPED BACK AT 3 LOCATIONS). I BELIEVE THIS SITUATION COULD HAVE BEEN AVOIDED BY SOME SIMPLE ACTIONS. FIRST; AFTER THE ACFT WAS TOWED TO THE NEW PARKING LOCATION BY LINE SVC; I SHOULD HAVE TAKEN THE TIME TO BECOME MORE FAMILIAR WITH THE TAXI AREA AND THE EXIT RTES PRIOR TO BOARDING THE ACFT. WHEN I TAXIED INTO THE ARPT; I ORIGINALLY PARKED THE ACFT NEAR THE CTR OF THE RAMP. LINE SVC THEN TOWED THE ACFT CLOSER TO THE FBO; AND INTO THE CORNER OF THE RAMP. THIS WAS MY FIRST FLT INTO ZZZ; AND I SHOULD HAVE REVIEWED THE AREA PRIOR TO TAXI; NOT ASSUMED THAT JUST BECAUSE THERE ARE TAXI LINES PAINTED; THEN ADEQUATE CLRNC IS PROVIDED. I SHOULD HAVE LOOKED FOR ALTERNATE TAXI RTES; RATHER THAN JUST TURN TO THE CLOSEST TXWY. ALSO; I WILL GIVE MYSELF MORE OF A CUSHION ON SPACING WHEN DETERMINING WING CLRNC. IF I HAD NOT ACCEPTED THE MINIMAL CLRNC PRIOR TO THE TIP PASSING THE CORNER OF THE HANGAR; I COULD HAVE SHUT DOWN THE ENGS AND HAD LINE SVC TOW THE ACFT TO A MORE DESIRABLE LOCATION/POS ON THE RAMP.
