HARTFORD, Conn. (AP) — United Technologies Corp. said Thursday that its second-quarter profit ticked up just 1 percent as orders fell at its jet engine and elevator businesses.

The company also said it received full regulatory approval for its purchase of Goodrich Corp. and has closed the $18.4 billion deal, the biggest deal ever in the aircraft industry. The Justice Department said United Technologies will have to sell Goodrich’s Electric Power Systems business and Pump and Engine Controls business as part of the approval, as well as Goodrich’s interest in a joint venture with Rolls-Royce. United Technologies said the regulatory conditions were expected.
