What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The acft reportedly departed mco rwy 18R at approximately 1536Z enroute to opf. Upon ATC transfer to mia center (zma), the pilot advised they needed to return to mco for landing. After landing, it was determined that the right engine upper cowling had separated from the aircraft, resulting in minor damage to the cowling, engine and aircraft. The aircraft had received maintenance at mco before the flight at a 145 repair station (CNQ8). The maintenance involved removal and reinstallation of the RH upper cowling. The qa mgr reported that two mechanics had reinstalled the engine cowlings after performing engine maintenance, and each mistakenly thought the other had fastened the RH upper cowling fasteners. The inspector who subsequently inspected their work for completion visually checked the fasteners for security while standing on the ground, but he did not use a ladder or other means to climb up and physically check the fasteners for security.
