Narrative:
I was departing the ramp area to transition to the taxiway at gwinnett county airport (lzu). As I was taxiing to the end of the ramp where it intersects the txwys, the aircraft left the paved surfaced area and went down a small grade that was grassed. This grassed area was between an upper and lower paved ramp. The aircraft went from this grassed area back onto the paved surface. I was concerned that the propeller may have come in contact with the lower ramp surface, so I contacted ground control and requested clearance to taxi back to my starting point on the airport (approximately 75 yards). After engine shutdown, it was determined that approximately 6 inches of the propeller was damaged. There were propeller strike marks in the pavement. Contributing factors included an unfamiliarity with the ramp area, a visual illusion that the ramp was continuous and an inability to see clearly over the nose of the aircraft due to seating position and high instrument glare shield. To prevent a recurrence of this type of incident, I will visually inspect the ramp area for potential hazardous conditions prior to taxiing.
Original NASA ASRS Text
Title: PLT OF MS0P, INEXPERIENCED IN TYPE, FAILED TO REALIZE THAT THE PAVED SURFACE ON WHICH HE WAS TAXIING DID NOT CONTINUE IN HIS DIRECTION OF TAXI. A TXWY EXCURSION FOLLOWED.
Narrative: I WAS DEPARTING THE RAMP AREA TO TRANSITION TO THE TXWY AT GWINNETT COUNTY ARPT (LZU). AS I WAS TAXIING TO THE END OF THE RAMP WHERE IT INTERSECTS THE TXWYS, THE ACFT LEFT THE PAVED SURFACED AREA AND WENT DOWN A SMALL GRADE THAT WAS GRASSED. THIS GRASSED AREA WAS BTWN AN UPPER AND LOWER PAVED RAMP. THE ACFT WENT FROM THIS GRASSED AREA BACK ONTO THE PAVED SURFACE. I WAS CONCERNED THAT THE PROP MAY HAVE COME IN CONTACT WITH THE LOWER RAMP SURFACE, SO I CONTACTED GND CTL AND REQUESTED CLRNC TO TAXI BACK TO MY STARTING POINT ON THE ARPT (APPROX 75 YARDS). AFTER ENG SHUTDOWN, IT WAS DETERMINED THAT APPROX 6 INCHES OF THE PROP WAS DAMAGED. THERE WERE PROP STRIKE MARKS IN THE PAVEMENT. CONTRIBUTING FACTORS INCLUDED AN UNFAMILIARITY WITH THE RAMP AREA, A VISUAL ILLUSION THAT THE RAMP WAS CONTINUOUS AND AN INABILITY TO SEE CLRLY OVER THE NOSE OF THE ACFT DUE TO SEATING POS AND HIGH INST GLARE SHIELD. TO PREVENT A RECURRENCE OF THIS TYPE OF INCIDENT, I WILL VISUALLY INSPECT THE RAMP AREA FOR POTENTIAL HAZARDOUS CONDITIONS PRIOR TO TAXIING.
