POSSIBLE JET BLAST DAMAGE DURING TAXI.

Narrative

DURING A NORMAL PAX PICKUP STOP AT ADAMS FIELD ON JAN/95; OUR GULFSTREAM IV WAS PARKED BY A LINEMAN ON THE RAMP AT FBO. WE PICKED UP OUR PAX AND FUELED THE ACFT TO APPROX 23000 LBS OF FUEL. (THIS RESULTED IN THE ACFT WEIGHING 68000 LBS.) WE STARTED OUT ON THE SECOND LEG OF AN EXTENDED OVERSEAS TRIP WITH ALL SYS NORMAL FOLLOWING THE ENG START SEQUENCED. AFTER RECEIVING OUR CLRNC TO GANDER; NEWFOUNDLAND; AND TAXI CLRNC; THE PF; OUR CHIEF PLT; APPLIED PWR TO START THE ACFT MOVEMENT. I ASSURE YOU; HE USED THE MINIMUM PWR POSSIBLE TO START THE ACFT MOVING AND TO EXECUTE THE REQUIRED R TURN OUT OF THE PARKING SPACE. AT THIS POINT; I'D LIKE TO SAY IN MY MORE THAN 20 YRS OF BEING AROUND ACFT; I HAVE NEVER SEEN ANYONE MORE CAUTIOUS AND SMOOTH IN OP OF ANY ACFT THAN OUR CHIEF PLT! WE TAXIED OUT WITH ALL INDICATIONS NORMAL AND THE REMAINDER OF THE AROUND-THE-WORLD FLT WAS ROUTINE. UPON RETURN TO MSY; OUR HOME BASE; I IMMEDIATELY HAD TO CATCH A COMMERCIAL FLT TO TEXAS AS MY FATHER WAS IN THE HOSPITAL. I HAD NO IDEA OF ANY OF THIS UNTIL MY RETURN AND OBVIOUSLY THE 10 DAY DEADLINE HAD PASSED. HOWEVER; I FEEL SO STRONGLY ABOUT THIS SIT; I FEEL THE NEED TO STILL SUBMIT THE ASRS FORM. THE CHIEF PLT DIDN'T FIND OUT OF THIS INCIDENT UNTIL RETURNING FROM THE TRIP WHEN HE READ IT IN AN INTERNAL COMPANY MEMO. THIS TYPE OF SIT COULD BE PREVENTED BY NOT MIXING LIGHT ACFT IN THE SAME RAMP SPACE AS ACFT WEIGHING 75000 LBS. THERE IS A MEETING SCHEDULED NEXT WK AT THE FBO IN WHICH DISCUSSIONS WILL TAKE PLACE TO PREVENT THIS FROM EVER HAPPENING AGAIN (THE FAA IS SENDING A REPRESENTATIVE). THE OPERATOR OF THE SMALL MOONEY IS ALLEGING SOME DAMAGE TO HIS PAINT WAS CAUSED BY TRASH BLOWING ACROSS THE RAMP DUE TO OUR JET ENG THRUST. AGAIN; IT IS MY OPINION; AND THAT IS WHAT I GET PAID FOR; THAT THE CHIEF PLT (PF) USED THE ABSOLUTE MINIMUM PWR TO MOVE OUR ACFT -- NO ONE COULD HAVE DONE IT ANY SMOOTHER!
