Summary
We propose to adopt a new airworthiness directive (AD) for all Model SAAB 2000 Airplanes. This proposed AD was prompted by reports that environmentally friendly de-icing agents used on certain electrical connectors and braids could cause corrosion damage. This proposed AD would require performing in certain locations a detailed inspection for corrosion of the electrical and electronics installation, and if corrosion is found repairing each affected harness braid or replacing each affected component and/or wiring harness. We are proposing this AD to detect and correct corrosion of critical system wiring, which could result in arcing and, in combination with other factors, a fire and consequent damage to the airplane.
