Great Wall Airlines has signed an exclusive agreement to use Pratt & Whitney's EcoPower engine wash service on its fleet of PW4056 engines through 2010. All engines washes will be conducted at EcoPower's Amsterdam service center.

This is the first Chinese customer for EcoPower service. Pratt & Whitney is a United Technologies Corp. company.

Mr. Kuah Boon Kiam, president, Great Wall Airlines said, "We are pleased to add EcoPower service to our maintenance portfolio as we believe this will bring more customer value. In July, Great Wall Airlines signed a seven-year Fleet Management Program agreement with Pratt & Whitney covering three Boeing 747-400 freighters powered by PW4000-94 engines."
