GND CONFLICT -- TUG STRIKES ITS OWN ACFT DURING PUSHBACK.

Narrative

ON JAN/XX/95 OUR ACFT; A757 FLT; WAS PUSHED BACK FROM THE GATE AT PHILADELPHIA INTL ARPT. THE PUSHBACK CLRNC WAS GIVEN BY THE COMPANY -- RUN TWR EMPLOYEES. WHILE THE PUSHBACK WAS IN PROGRESS ANOTHER ACFT ON THE OPPOSITE TERMINAL WAS ALSO CLRED FOR PUSHBACK. THE MECHS PUSHING OUR 757 TYPE ACFT OBSERVED THE OTHER ACFT AND TURNED THE 757 SHARPLY TO AVOID JETBLASTING THE OTHER ACFT AND PUSHBACK CREW. THE TUG STRUCK THE 757 ACFT CAUSING A 2 BY 2 SCRATCHED AREA ON THE LOWER FUSELAGE OF THE ACFT. THE ACFT RETURNED TO THE GATE; THE AREA WAS INSPECTED AND FOUND TO BE WITHIN THE 757 STRUCTURAL REPAIR MANUAL SVCABLE LIMITS FOR DISPATCH. THE 2 MECHS INVOLVED WERE DRUG TESTED AT THE ARPT MEDICAL CTR. THE COMPANY TWR OPERATORS GIVE MULTI PUSHBACK CLRNCS ALL THE TIME; AND CREATE SAFETY PROBS FOR PUSHBACK CREWS. THESE COMPANY CTLED TWR OPERATORS QUALIFICATIONS ARE QUESTIONABLE AND THESE OPERATORS ARE NOT DRUG TESTED AFTER AN INCIDENT OCCURS. BOTH SUPVRS AND TWR OPERATORS ARE RELUCTANT TO IDENT OPERATORS INVOLVED IN THESE INCIDENTS.
