AD 2008-04-05 Airworthiness Directives; Eurocopter Deutschland Model EC135 Helicopters

Models named: EC135. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Model EC135 helicopters, serial number 0005 up to and including 0576, certificated in any category.

Within 25 hours time-in-service (TIS), unless already done, do the following: (1) Inspect the wiring harnesses for chafing and wear in the areas shown in Figure 1 of Eurocopter Alert Service Bulletin EC135-53A-017, Revision 1, dated June 22, 2007 (ASB). (i) If chafing or wear is found on the wiring harness, before further flight, replace the wiring harness with an airworthy wiring harness. (ii) If no chafing or wear is found, modify the side channel covers by affixing double-sided adhesive tape in the area depicted in Figure 2 of the ASB by following the Accomplishment Instructions, paragraph C, of the ASB. (2) Modify the attachment of the copilot collective lever cover as depicted in Figure 3 of the ASB by following the Accomplishment Instructions, paragraph D, of the ASB. (3) Attach chafing protection to the wiring harnesses and replace affected screws as depicted in and in accordance with Figure 4 of the ASB and by following the Accomplishment Instructions, paragraphs E and F, of the ASB. Paragraph F(2) of the ASB applies only to helicopters with a copilot collective lever cover. Differences Between the FAA AD and the MCAI (g) This AD differs from the MCAI as follows: (1) We do not require contacting the manufacturer for further instructions if a wiring harness is damaged but require that you replace a damaged wiring harness with an airworthy wiring harness. (2) We do not require a February 28, 2007, compliance time because that date has passed. (3) We have used the helicopter S/N 0005 up to and including S/N 0576 as stated in the service information rather than the helicopter S/N 0005 up to and including 0654 as stated in the MCAI. (4) We refer to the compliance time as “hours TIS” rather than “flight hours.” Other FAA AD Provisions (h) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Safety Management Group, 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: Carroll Wright, Aviation Safety Engineer, Rotorcraft Directorate, Regulations and Policy Group, Fort Worth, Texas 76193-0111, telephone (817) 222-5120, fax (817) 222-5961. (2) Airworthy Product: Use only FAA-approved corrective actions. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent) if the State of Design has an appropriate bilateral agreement with the United States. You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056. Related Information (i) Mandatory Continuing Airworthiness Information (MCAI) Emergency Airworthiness Directive No. 2007-0021-E, dated January 19, 2007, contains related information.
