Narrative

DUE TO THE PRESENCE OF FREEZING PRECIP; OUR ACFT WAS IN NEED OF DEICING BEFORE DEP. DUE TO THE AVAILABILITY OF TYPE I FLUID ONLY; THE CAPT AND I DECIDED TO DEICE THE ACFT WITHOUT PAX ABOARD AND DEICE A SECOND TIME AT THE END OF THE DEP RWY. THIS WAS DUE TO THE HOLDOVER TIME OF TYPE I FLUID IN LIGHT FREEZING RAIN (2-6 MINS). HOWEVER; DURING THE FIRST DEICE PROCESS; THE AMOUNT OF ICE ACCUMULATION ON THE ACFT WAS BEYOND THE CAPABILITY OF THE FBO'S DEICING EQUIP AND ONLY ABOUT 1/2 OF THE ACFT WAS DEICED AS THE FBO WAS RUNNING LOW ON FLUID. A DECISION WAS MADE TO THEN TAXI THE ACFT WITH NO PAX ABOARD TO A HANGAR IN ORDER TO AVOID ANY MORE CONTAMINATION OF THE ACFT. DURING TAXI; WE FOLLOWED AN ARPT PLOW AS HE PLOWED A PATH THROUGH THE 1-2 INCHES OF SNOW THAT HAD FALLEN. THE CAPT GAVE NO INDICATION DURING TAXI THAT THE BRAKING ACTION WAS POOR. CURRENT ARPT FIELD CONDITIONS HAD ALL SURFACES BRAKING ACTION POOR. DURING TAXI BTWN 2 ROWS OF HANGARS; THE L WINGTIP STRUCK THE CORNER OF THE HANGAR. I BELIEVE WHAT REALLY CAUSED THE ACCIDENT WAS THE COMBINATION OF INFERIOR FBO DEICE EQUIP; THE UNAVAILABILITY OF TYPE II FLUID ON THE FIELD; AND IMPROPER POSITIONING OF ACFT WINGWALKERS DURING TAXI. HAD ALL THE ICE BEEN REMOVED THE FIRST TIME THE ACFT WOULD NOT HAVE NEEDED TO BE PUT IN A HANGAR. HAD ALL THE CAPT'S WINDOWS BEEN CLRED OF SNOW; HE MAY HAVE HAD A BETTER VIEW OF HIS WINGTIP AND AVOIDED THE COLLISION.
