COMMUTER LTT ROLLED INTO GPU CAUSING DAMAGE TO ACFT.

Narrative

I HAD JUST FINISHED MY REGULARLY SCHEDULED SECTION AT XA00PM. FLT CTL IN DAYTON; OH; WANTED ME TO CALL IN. I CALLED AND THEY ASK ME TO DO AN ADDITIONAL SECTION. I REQUESTED NOT TO DUE TO AN APPOINTMENT WITH A SURGEON MY WIFE AND I HAD MADE 2 1/2 WKS AGO. I WAS HAVING MY PARENTS IN THAT DAY ALSO FROM OUT OF STATE AND HAD ONLY A SHORT PERIOD TO VISIT. FLT CTL TOLD ME THAT IF I DIDN'T FLY THE SECTION I COULD LOOK FOR ANOTHER JOB. I RELUCTANTLY ACCEPTED WHAT I COULD NOT CHANGE AND HAD MY WIFE CANCEL THE APPOINTMENT. MY F/O THEN INFORMED ME HE HAD TAKEN ILL AND COULD NOT FLY. SCHEDULING CALLED IN ANOTHER F/O. 5 HRS IN ACFT AND ONLY 1 PREVIOUS REPOSITION FLT. NO REGULAR FLT DUTY. I WENT TO THE HANGAR AND PREFLTED THE ACFT. FLT CTL DID NOT GET INTO PHL BY XB30 I WOULD BE GETTING HOME LATE AND COULD NOT GUARANTEE POSITIVE SPACE HOME. MAINT PULLED ACFT OUT OF HANGAR AND DID NOT CHK IT OR SET BRAKE. DURING MY PRESTART CHKLIST I SET BRAKE AND HELD BRAKES AT PEDAL FOR ENG START. AFTER STARTING #2 ENG I REQUESTED GPU TO BE REMOVED AND START #1. AFTER STARTING #1 AND SEEING GND PERSONNEL MOVING AWAY TO GPU I COMPETED MY FLOW AND RELEASED PARKING BRAKE. I DID NOT HAVE SUFFICIENT PRESSURE ON BRAKES TO PREVENT ACFT FROM ROLLING 8' INTO GPU. ACFT SUSTAINED DAMAGE TO NOSE CONE AND MINOR DAMAGE TO RADAR ANTENNA. MY HEAD WAS IN COCKPIT WHEN ACFT STARTED TKOF ROLL. F/O WAS NEW AND WAS NO HELP; BUT CAN'T BE BLAMED DUE TO LACK OF EXPERIENCE. MANY FACTORS LED TO INCIDENT. RUSH BY COMPANY TO GET GOING TIME LIMITS TO PREVENT GETTING HOME LATE (AS IT WAS IT WAS 13.7 HR DAY). PROBS AT HOME. NEW F/O. FEAR OF LOSING JOB IF DID NOT GO. MY BEING IN TOO BIG A HURRY. I WILL NEVER BE INTIMIDATED BY COMPANY AGAIN.
