Three PPG aerospace business facilities have been honored by Northrop Grumman Corp. as 2009 Platinum Source Preferred suppliers for their performance and quality in delivering transparencies, coatings, sealants, and other value-added services.

The Huntsville, Ala., aircraft transparencies facility and the Los Angeles and Atlanta application support centers (ASCs) have received the award, which recognizes companies for achieving distinction in product quality, on-time delivery, customer satisfaction, and robust lean processes.

“Being honored for a job well done is no small matter, especially when that honor comes from a company as prestigious as Northrop Grumman,” said Dave Morris, PPG Aerospace vice president and general manager for the Americas. “We are especially pleased by the continued achievement of our people at the Los Angeles and Atlanta ASCs, and the award-winning performance of the people at our Huntsville plant. The PPG Aerospace team is committed to continuous improvement in quality and customer service through operational excellence in our manufacturing plants and ASCs.”

PPG’s ASCs supply Northrop Grumman with coatings, sealants and custom-packaged third-party chemicals. The Los Angeles center in Valencia, Calif., supplies the Northrop Grumman Aerospace Systems facilities in Palmdale and El Segundo, Calif. The Atlanta center in Kennesaw, Ga., supplies Northrop Grumman’s St. Augustine and Melbourne, Fla., facilities.
