EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2011-0079 

Date: 05 May 2011 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and 

of the European third countries that participate in the activities of EASA under Article 66 of 

that Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD unless otherwise specified by the Agency 

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]. 

Type Approval Holder’s Name : 

Saab AB, Aeronautics 

Type/Model designation(s) : 

2000 aeroplanes 

TCDS Number : EASA.A.069 

Foreign AD : Not applicable 

Supersedure : None 

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-icing 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 identified 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 corrected, could lead to damage of critical 

system wiring, possibly resulting in arcing 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. 

Effective Date: 19 May 2011
