Boeing, Airbus voice doubts over US$23b supplier merger

New York

BOEING Co and Airbus SE voiced concerns about a proposed tie-up of two leading suppliers on Tuesday, potentially upsetting United Technologies Corp's US$23 billion acquisition of Rockwell Collins Inc.

The world's largest planemakers added to the chorus of sceptics of a deal that would create an aerospace behemoth with a range of products to outfit jetliners and warplanes. Investors sent United Technologies shares plunging by the most in two years, while credit ratings companies said the manufacturer risks downgrades.
