An Airbus A319-111, N904FR, Frontier Flight 851, experienced a loss of the right lower engine cowling on initial climb out at 200 feet, and the loss of the yellow hydraulic pressure system. The flight crew leveled the airplane off at 3,000 feet and declared an emergency. The flight was cleared for an approach to runway 9 left and landed without further incident at the William B. Hartsfield Atlanta International Airport, Atlanta, Georgia at 06:42. The airplane received minor damage.
The flight was originating from the William B. Hartsfield International Airport, Atlanta, Georgia, at 06:24.The planned destination airport was Denver International Airport, Denver, Colorado.
The PIC stated the flight deck crew arrived at the airplane at the required show time. The gate agent informed them that a mechanic was working on the brakes. The PIC and FO went down to the airplane and did not see anyone and the logbook was not on the flight deck. The FO departed the flight deck, completed the walk around inspection, and observed nothing unusual. A short time later the mechanic brought the logbook to the flight deck and explained to the PIC that he had worked on the No.1 brake and placed the temperature sensor on the minimum
equipment list.

Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this incident to be: The mechanics failure to follow procedures and directives in securing the lower engine cowling after maintenance, and the failure of the first officer to follow the checklist to ensure the engine cowling was secured during the walk around inspection resulting in the separation of the right lower engine cowling during initial take off climb.
