The plant is operated by a 50-50 joint venture between the two companies and employs 600 people. Work will shift to other locations, and the plant is expected to close by January.
American says it will provide job opportunities for the 500 plant workers who are represented by a union and will create more than 100 union jobs in the Dallas-Fort Worth area to offset the closure.
American said today that it accepted a Rolls Royce request to dissolve the joint venture and close the Texas Aero Engine Services plant in Fort Worth.
Shares of American's parent, American Airlines Group Inc, rose 62 cents to USD 39.70 in midday trading today. The engine maker is a unit of Rolls-Royce Holdings PLC.
