Narrative

ON OCT/XX/97 AT AROUND XA30L AT COS ARPT; WE WERE CLRED TO TAXI TO RWY 30 FROM FBO VIA TXWY A. MY FO FAILED TO SEE THE HOLD SHORT LINE ON THE W SIDE OF RWY 30 AND TAXIED ONTO THE RWY. A LIGHT ACFT ON FINAL APCH WAS ASKED TO GAR DUE TO US BEING ON THE RWY. THE TWR CTLR THEN CLRED US FOR TKOF AND NOTHING ELSE WAS SAID. I FEEL THAT MY FO FAILED TO SEE THE HOLD SHORT LINE DUE TO LOW LIGHTING AND DUE TO THE FACT THAT HE WAS UNFAMILIAR WITH THE ARPT. I DID NOT SEE THE HOLD SHORT LINE BECAUSE I WAS TURNING ON THE XPONDER AND LOOKING AT THE CHKLIST. IN THE FUTURE; TO PREVENT THIS FROM HAPPENING AGAIN; I WILL NEED TO PAY MORE ATTN TO THE FO AND HIS ACTIONS. SUPPLEMENTAL INFO FROM ACN 382343: WE WERE SUBSEQUENTLY CLRED FOR TKOF AND THE SINGLE ENG ACFT PROCEEDED TO GAR AND RE-ENTERED THE PATTERN AND LANDED AFTER OUR DEP. THE PROB WAS DISCOVERED WHEN I LOOKED TO MY L AND SAW THE DISPLACED THRESHOLD. CONTRIBUTING FACTORS WERE THE DIMLY LIT AREA AT THE APCH END OF THE RWY AND THE INABILITY TO SEE THE HOLD SHORT LINES ON THE PAVEMENT; AND THE CONSTRUCTION ON THE ARPT SURFACE CAUSING SOME CONFUSION FOR THE CREW DURING THE TAXI FROM THE RAMP TO THE RWY 30 APCH END.
