PRODUCT: All Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. SUBJECT: Airworthiness Directive 2012-10-06 ACTION: Final Rule
SUMMARY: This AD was prompted by reports that environmentally friendly de-icing agents used on certain electrical connectors and braids could cause corrosion damage. This AD requires 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.
The FAA is issuing 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.
