Lee Aerospace has received parts manufacturing approval (PMA) of its CoolView windows for the side cockpit windows on the Beechjet 400, 400A, and 400T, the Wichita-based supplier announced last week. CoolView, which blocks up to 62 percent of infrared rays and virtually all UV rays via an internal metallic barrier, were previously PMA'd for Beechcraft King Airs and Hawkers.

"I think as a follow-on to the previous PMAs we have in the aftermarket, pilots and passengers alike are specifically asking for this technology on their aircraft, which has given us a long list of projects to work on this year," said Lee Aerospace chief engineer Joel Weber.

Its CoolView windows will be on display on a Beechcraft King Air C90 next month at EAA AirVenture next month in Oshkosh, Wisconsin. There, the company will also offer aircraft window polishing as an authorized service provider for airshow attendees. “This is the first year we are offering the window polishing services at Oshkosh,” said Lee Aerospace CEO Jim Lee. “We will have a mobile team of our experienced technicians right there at the show.”
