The antitrust organization of the European Union opened an in-depth investigation into Hartford-based United Technologies Corp. for its attempted $18.4 billion takeover of aerospace supplier Goodrich Corp.
The European Commission is concerned about potential competition concerns for engine controls, AC power generators, fuel nozzles and aftermarket services.
UTC had hoped to complete the acquisition by mid-2012, but the European investigation will last until Aug. 9. The regulators will decide if the transaction reduces effective competition in the European Economic Area.
Such a decision would block the deal.
The Hartford conglomerate already is making several moves to finalize the transaction first proposed in September, including issuing around $2 billion in stock and selling some units of Pratt & Whitney Rocketdyne, Clipper Wind and Hamilton Sundstrand.
