Narrative:

Following a flight that required maintenance on the right #2 engine air inlet deice boot and valve, a takeoff was performed for a scheduled flight to bristol, tn, (tri-city airport). Shortly after takeoff, the cabin flight attendant noticed that the right outboard engine cowling had become unfastened and was opening due to the propeller wash and slipstream. The aircraft was brought back to atl for an uneventful landing and the cowling was refastened with minor sheetmetal deformity. The walk around was performed after said maintenance actions were completed with the first officer noting nothing unusual reference engine cowlings. It remains unclr how the engine cowling became dislodged during flight.
