My partner and I had arrived at the FBO in the afternoon. We began pre-flighting our assigned aircraft. My partner had brought to my attention something on the stabilizer which required a close inspection.  As I climbed up the ladder and put my hand on the horizontal stabilizer; I noticed there was significant free play. This is a result of the four horizontal stabilizer attach point bolts; and bushings being worn out. (Information provided by the technician).The Federal Aviation Administration holds aircraft manufacturer to high tolerances. I don't know why this problem has slipped through the cracks. This is a potential threat to the safety of our aircraft; our pilots; and their owners. Immediate action is necessary to have a fleetwide inspection. The current inspection method is inadequate. The bolts; and attach point bushings need immediate attention! I would suggest a fleet wide inspection; and replacement of the horizontal stabilizer attach point bolts; and bushings.
Upon preflight; noticed a possible break in tape on the right side of the leading edge of the boot and the tape. The first officer checked the break on a ladder only to realize there was excessive play in the horizontal stabilizer. We called a mechanic; he verified there was considerable more play in this than three others he or the first officer checked on the ramp. Notified Maintenance and wrote the horizontal stabilizer up for inspection.I suggest physically checking each horizontal stabilizer.
During preflight CE-560XL crew discovered excessive horizontal stabilizer play because of excessive attach bolts and bushings wear.
