Narrative:

Engines were started in normal manner. Clearance to power back was received. Normal guideman procedures were used, no turns during power back were briefed. Power back proceeded normally. We were waved forward to terminate the power back, at which I believed to be late into the power back. This was confirmed by the aircraft leaving the cement ramp and rolling about 2 ft onto the asphalt apron. The apron is approximately 2 inches lower than the cement ramp, I felt the aircraft drop off this lip and accelerate aft. At this time I added more forward power. This did not adequately stop the aircraft. I then tapped the brakes lightly. The nose strut went to the full extension stop. Nose gear did not leave ground. At this point aircraft was stopped and I called the #1 flight attendant to ensure the cabin was in order and check on the cabin crew. All was found well except flight attendant #2 received a bruise on her posterior due to the sudden stop. Maintenance was called to inspect nose and main landing gear for damage, no damage found. Aircraft was then marshalled onto the ramp. Remainder of flight proceeded normally.

Title: MLG ON PWR BACK GOES OVER EDGE OF RAMP.

Narrative: ENGS WERE STARTED IN NORMAL MANNER. CLRNC TO PWR BACK WAS RECEIVED. NORMAL GUIDEMAN PROCS WERE USED, NO TURNS DURING PWR BACK WERE BRIEFED. PWR BACK PROCEEDED NORMALLY. WE WERE WAVED FORWARD TO TERMINATE THE PWR BACK, AT WHICH I BELIEVED TO BE LATE INTO THE PWR BACK. THIS WAS CONFIRMED BY THE ACFT LEAVING THE CEMENT RAMP AND ROLLING ABOUT 2 FT ONTO THE ASPHALT APRON. THE APRON IS APPROX 2 INCHES LOWER THAN THE CEMENT RAMP, I FELT THE ACFT DROP OFF THIS LIP AND ACCELERATE AFT. AT THIS TIME I ADDED MORE FORWARD PWR. THIS DID NOT ADEQUATELY STOP THE ACFT. I THEN TAPPED THE BRAKES LIGHTLY. THE NOSE STRUT WENT TO THE FULL EXTENSION STOP. NOSE GEAR DID NOT LEAVE GND. AT THIS POINT ACFT WAS STOPPED AND I CALLED THE #1 FLT ATTENDANT TO ENSURE THE CABIN WAS IN ORDER AND CHK ON THE CABIN CREW. ALL WAS FOUND WELL EXCEPT FLT ATTENDANT #2 RECEIVED A BRUISE ON HER POSTERIOR DUE TO THE SUDDEN STOP. MAINT WAS CALLED TO INSPECT NOSE AND MAIN LNDG GEAR FOR DAMAGE, NO DAMAGE FOUND. ACFT WAS THEN MARSHALLED ONTO THE RAMP. REMAINDER OF FLT PROCEEDED NORMALLY.
