Mechanics, you can minimize downtime and save your unit tons of money by repairing damaged acrylic aircraft windows instead of ordering new ones.
Tossing out acrylic aircraft windows because for scratches, blemishes or minor damage is costly. Instead, repair them while they remain in the frame on the aircraft with the window repair kit, NSN 4920-01-569-3630, PN EZ2050B-1. The kit was improved so you may have the original part number, PN EZ2050B.
The window repair kit is included in the unit aviation shop set, NSN 4920-01-551-7472, and the AVIM sheet metal shop set, NSN 4920-01-600-7364. The kit contains an instruction manual and training DVD that explains the simple process for restoring acrylic aircraft windows.
Repairing acrylic windows is a good way to get in the habit of saving money, especially with tighter budgets. Also, check out Chapter 10 Aircraft Plastics of TM 1-1500-204-23-10 (Jul 92, w/Ch 6, Mar 15) for the window repair kit and how to use it.
