Required Actions
Inspect windshield panels to determine manufacturer and year. For PPG panels with November 1, 1978, through December 31, 1980, manufacturing dates, perform resistance checks. If resistance is out of tolerance, install placards restricting airspeed below 10,000 feet, or replace panels with LOF or non-PPG date-coded panels. Repeat inspections at 50-hour intervals until 200 flight hours, then extend to 1,500 hours if within limits.
