Narrative:

After a routine training flight, my student and I were met exiting our C150L by an FAA inspector who asked to do a routine ramp inspection. After the inspection, the FAA inspector explained to us he considered the aircraft to be unairworthy due to items overlooked by my student and I during our preflight inspection. These items included missing screws, a loose tail tiedown ring, a suspected oil leak (later found none by a&P), and excessive play in the elevator center pivot bushing. I believe these things may have been noticed and reported before the flight had I done a more thorough preflight myself after my 35 hour student completed his. I will definitely keep this in mind in the future and remember student pilots may sometimes overlook things.
