No, there cannot (at least not legally). Aircraft are subject to strict maintenance and inspection requirements based on both calendar time and operating hours, and a certified mechanic must sign-off on the completed work. Out in rural areas there are a few private pilots who fly poorly maintained "beater" light airplanes and get away with it because authorities never show up at the local grass strip but this is never going to be tolerated in urban areas.
