On May 22, 2003, at 0845 mountain daylight time, a North American SNJ-6, N5485V, was substantially damaged when it departed the left side of the runway during landing at Double Eagle II Airport (AEG), Albuquerque, New Mexico. The airline transport pilot, the sole occupant on board, was not injured. Visual meteorological conditions prevailed for the cross-country flight being conducted under Title 14 CFR Part 91. No flight plan had been filed for the flight that originated from Santa Fe, New Mexico, at 0812. According to the pilot, he was on approach for runway 22. He said there was another aircraft in the pattern, doing touch-and-go landings. The pilot stated that the separation was adequate; however, he "felt the pressure" of the aircraft following him. The landing was uneventful; however, in his "haste to clear the runway, [he] relaxed the back pressure [which allowed] the tail to come back up." The airplane drifted to the left, departed the runway and the left main wheel struck an asphalt walkway. Both the left and the right main gear collapsed, the right wing tip rib was bent, and the right main fuel tank was punctured.
