Narrative:
This was a pwrback from a gate in mem close to a taxiway. After the ground marshaller signaled us to terminate the pwrback, the aircraft continued backwards due to its heavy weight (107000 pounds) and the downslope of the taxiway. We could not see how close we were to the edge. Further, the marshaller turned us to the right to avoid a ground loading vehicle (for an air carrier B767). This was distracting. The aircraft continued backwards after we came out of reverse and went off the taxiway into the mud. The company has since terminated pwrbacks at this gate.
Original NASA ASRS Text
Title: CAPT OF AN MLG FAILED TO STOP ACFT AFTER PWRBACK DUE TO A SLOPE IN THE TXWY RESULTING IN THE ACFT BEING STRANDED IN MUD.
Narrative: THIS WAS A PWRBACK FROM A GATE IN MEM CLOSE TO A TXWY. AFTER THE GND MARSHALLER SIGNALED US TO TERMINATE THE PWRBACK, THE ACFT CONTINUED BACKWARDS DUE TO ITS HVY WT (107000 LBS) AND THE DOWNSLOPE OF THE TXWY. WE COULD NOT SEE HOW CLOSE WE WERE TO THE EDGE. FURTHER, THE MARSHALLER TURNED US TO THE R TO AVOID A GND LOADING VEHICLE (FOR AN ACR B767). THIS WAS DISTRACTING. THE ACFT CONTINUED BACKWARDS AFTER WE CAME OUT OF REVERSE AND WENT OFF THE TXWY INTO THE MUD. THE COMPANY HAS SINCE TERMINATED PWRBACKS AT THIS GATE.
