Once in the terminal area, the tower advised the pilot to enter a right base for runway 24. The pilot lowered the landing gear, and verbalized it was down with "three in the green" and "one in the mirror." The instructor looked at the landing gear indicator, and confirmed the gear was down and locked. The instructor called for the "prelanding checklist," and the pilot confirmed it was complete. The airplane was cleared to land. On short final, the instructor called out mixture rich, propellers full forward, and landing gear down with "three green." The airplane touched down and the instructor commented to the pilot, "nice landing." The right main landing gear then collapsed, and the airplane veered to the right. The right wing struck a runway light, and the nose gear collapsed. The airplane came to a stop up right with the left main landing gear still down and locked. The instructor along with the pilot exited the airplane. Examination of the right main landing gear revealed no preimpact failures or malfunctions. In addition, a witness saw the nose wheel, along with the left and right main landing gear in the down position when the airplane landed. ## Factual narrative On October 10, 2001, about 1600 eastern daylight time, a Piper PA-34-200T, N91284, was substantially damaged during landing at the Northeast Philadelphia Airport (PNE), Philadelphia, Pennsylvania.
