On August 22, 1998, about 1400 Eastern Daylight Time, a Cessna 150L, N7513G, was substantially damaged while landing at the Greater Cumberland Regional Airport (CBE), Cumberland, Maryland. The certificated private pilot was not injured. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight conducted under 14 CFR Part 91. The flight originated from CBE, about 1300. The pilot stated that after departure, she went to the local training area to practiced maneuvers. Upon returning to the airport, she completed three touch and go landings, and decided to do one more additional full stop landing. The traffic pattern was flown the same as the three previous landings. Just prior to touchdown, the pilot flared the airplane to high, contacting the runway hard on all three tires. The airplane bounced and began to porpoise. Before power was added to recover from the porpoise, the airplane impacted the runway again, nose first. The nose gear collapsed, and the airplane came to rest in the center of the runway. The pilot reported that she received her private pilot's license 4 months prior to the accident, and had accumulated a total of 151 flight hours. She stated that she flew 7 hours in the last 90 days.
