Narrative

DUE TO PROGRAMS UNDERWAY AT MY AIRLINE TO CUT COSTS; A GREAT DEAL OF GND HANDLING FUNCTIONS ARE HANDLED BY NEW 'CONTRACTOR' PERSONNEL. IN ADDITION; LONG-TIME MECHS ARE BEING MOVED TO NIGHT SHIFTS AND AWAY FROM SMALL STATIONS. AT BTR THE ONLY LARGE PUSHBACK TUG HAS BEEN INOP FOR SEVERAL WKS AND ACFT TOWING IS DONE USING A SMALL TUG NORMALLY USED FOR BAGGAGE CARTS. TODAY; WHILE OUR ACFT WAS UNDER TOW; THE DRIVER OF THE TUG LOST CTL AND THE TUG JACKKNIFED TO THE R; BREAKING THE TOW BAR AND CAUSING A RIDER (WHO WAS TRYING TO INSTRUCT THE TOW OPERATOR) TO FALL OFF. HE INJURED HIS LEG/KNEE AND WAS TAKEN TO THE HOSPITAL. MY CAPT WAS ABLE TO APPLY BRAKES ON OUR ACFT; WHICH SUSTAINED NO DAMAGE. IN MY OPINION; THIS INJURY WAS CAUSED BY POOR TRAINING OF CONTRACTOR PERSONNEL AND LACK OF PROPER TUG EQUIP. WE HAVE PROVIDED DETAILS TO OUR COMPANY SAFETY DIRECTOR AND CHIEF PLT; AND I DON'T BELIEVE THE FLC TO BE AT FAULT. HOWEVER; I WON'T ALLOW A SMALL TUG TO MOVE A BIG AIRPLANE AGAIN WHILE I'M A CREW MEMBER. SUPPLEMENTAL INFO FROM ACN 304780: DUE TO THE PROX OF COMMUTER ACFT PARKED BEHIND OUR B-727 WE WERE UNABLE TO PWR BACK FROM THE GATE. DURING THE PUSH; WHEN WE BEGAN ROLLING FORWARD; THE TUG DISAPPEARED FROM MY VIEW ON THE R SIDE OF THE ACFT. AT THAT TIME BOTH THE FO AND I RECOMMEND TO THE CAPT THAT HE STOP THE ACFT. THE FO IMMEDIATELY NOTIFIED GND CTL AND REQUESTED AN AMBULANCE. THE AGENT WAS TAKEN TO THE HOSPITAL. SUPPLEMENTAL INFO FROM ACN 303952: AN AGENT WAS RIDING ON THE TUG; FELL OFF AND WAS INJURED. PERHAPS IF THERE WERE MORE OPERABLE BACKUP EQUIP ON HAND; SUCH AS LONG WIRE HEAD SETS; LARGE AIRPLANE TUGS; AND APU'S; THIS MISHAP MIGHT NOT HAVE HAPPENED.
