### ATA 92 Electrical and Electronics Installation – Electrical Connectors and Braids – Inspection / Repair / Replacement

Manufacturer(s): Saab AB, Aeronautics (formerly Saab Aerosystems).

Applicability: Model 2000, all serial numbers.

Reason: Environmentally friendly de-/anti-ic ing agents (acetates or formats) are a known cause of corrosion damage to components of the Electrical Wiring Interconnection System (EWIS) on aeroplanes. Investigations by SAAB have identifi ed certain electrical connectors and braids which are susceptible to such damage, in zones 191 and 192 of the center wing fuselage and in zones 323, 332 and 342, affecting the wiring harnesses of elevator and rudder servos. This condition, if not detected and correc ted, could lead to damage of critical system wiring, possibly resulting in ar cing and, in combination with other factors, a fire and consequent damage to, or loss of, the aeroplane. To address this unsafe condition, SAAB have issued Service Bulletin (SB) 2000-92-005 and SB 2000-92-006 to provide instructions to detect unacceptable corrosion on electrical and electronic installation wiring. For the reasons described above, this AD requires a one-time inspection of the affected components in the designated area, the reporting of all inspections results to SAAB and, depending on findings, appropriate corrective action.
