MUNICH, Feb 19 (Reuters) - The chief executive of German

engine maker MTU Aeros said on Wednesday tariffs on plane

manufacturing would initially harm U.S. companies, including

airlines.

"Aviation is an oligopoly. The largest manufacturers of gas

turbines - GE and Pratt & Whitney - are U.S. companies. Tariffs

would first hurt the competitiveness of U.S. companies, and also

U.S. airlines," CEO Lars Wagner said.
