A PA31 PILOT LOADING FREIGHT WAS DISTRACTED BY EVENTS AROUND HIM AS THE ACFT WAS LOADED AND TOOK OFF WITH A WING LOCKER OPEN; SPILLING PACKAGES ON THE RWY.

Narrative

DURING LOADING OF MY FLT I WAS DISTR FROM LOADING THE WING LOCKER. WHILE AN ACR EMPLOYEE ADJUSTED THE BARRIER NET TO FIT THE REAR OF THE MAIN FUSELAGE; I WAS LOADING THE WING LOCKER WITH PACKAGES. EVENTUALLY; HE WAS ABLE TO SECURE THE BARRIER NET; THAT I WAS NOT STRONG ENOUGH TO SECURE; AND I BEGAN LOADING THE PACKAGES BEHIND THE BARRIER NET. I HAD WALKED AWAY FROM THE R WING LOCKER TO CHK ON THE PROGRESS; AND THEN SINCE HE HAD SUCCESS; I BEGAN LOADING THE REAR OF THE ACFT. CONSEQUENTLY; I DID NOT SECURE THE R WING LOCKER AND LOST SOME PACKAGES ON TAXI AND TKOF. I DID TAKE OFF WITHOUT SECURING THE R WING LOCKER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT MANY NEARBY EXTRANEOUS EVENTS WERE OCCURRING AROUND HIM DURING THE PERIOD OF HIS ACFT'S LOADING. ANOTHER ACFT WAS STARTING BESIDE HIM WHILE HIS LOADING WAS PROGRESSING FORCING HIM TO STOP AND COVER HIS EARS UNTIL THE ACFT LEFT AND THE OTHER PERSON LOADING FREIGHT WAS WORKING ON HIS OWN. IN THE END; THE REPORTER SIMPLY FAILED TO DO A FINAL WALK AROUND TO LOOK AT THE CARGO DOORS. THERE ARE NO LIGHTS ON ANY OF THE DOORS AND IT IS SIMPLY A MATTER OF THE A PILOT PREFLTING THE ACFT COMPLETELY.
