(2) If any chafed or damaged wires are found during any inspection required in paragraph (f)(1) of this AD, before further flight, repair the affected wire(s) and assure correct installation of the wiring in the flight deck overhead panels by reattaching or replacing the wire tie attachment holders and securing any loose wires to the wire tie attachment holders with plastic wire ties following: (i) Pages 1 through 10, Overhead Panel 5VE—Description, dated November 25, 2009, in subject 31-10-07, of Chapter 31, Indicating/Recording Systems, in RUAG Aerospace Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-00014-080184, Revision 3, October 30, 2012; (ii) Pages 201 through 208, Overhead Panel 5VE—Maintenance Practices, dated November 25, 2009, in subject 31-10-07, of Chapter 31, Indicating/Recording Systems, in RUAG Aerospace Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-00014-080184, Revision 3, October 30, 2012; (iii) Pages 1 and 2, Overhead Panel 6VE—Description, in subject 31-10-08, dated November 25, 2009, of Chapter 31, Indicating/Recording Systems, in RUAG Aerospace Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-00014-080184, Revision 3, October 30, 2012; (iv) Pages 201 through 204, Overhead Panel 6VE—Maintenance Practices, in subject 31-10-08, dated November 25, 2009, of Chapter 31, Indicating/Recording Systems, in RUAG Aerospace Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-00014-080184, Revision 3, October 30, 2012. (3) To comply with the actions of this AD, you may insert a copy of this AD or a copy of the required actions of this AD into the instructions for continued airworthiness section of the FAA-approved maintenance program (e.g., maintenance manual). This action may be done by an owner/operator (pilot) holding at least a private pilot certificate and must be entered into the airplane records showing compliance with this AD in accordance with 14 CFR 43.9 (a)(1)(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.173 or 135.439.

The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090; email: karl.schletzbaum@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as chafed or damaged wiring on the flight deck overhead panels (5VE and 6VE). We are issuing this AD to prevent chafing and damage to the wiring in the flight deck overhead panels, which could result in short-circuiting of related wiring and possibly lead to electrical failure of affected systems and potential fire in the flight deck.

This AD supersedes AD 2006-11-19, Amendment 39-14624 (71 FR 32268; June 5, 2006).
