Items 1, 2, 3, and 4 can result in radar performance problems while

Care must be exercised to be sure that only qualified personnel perform

repairs on the radome. Also, it is time well spent during preflight to

include checking the radome to be sure it remains in good repair. When

examining the radome, be certain the radar is not transmitting microwave

energy. See MPEL (Maximum Permissible Exposure Levels) in the

Appendix.
