AD 2010-10-07 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and Model ERJ 190 Airplanes

Models named: ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, -200 SU, ERJ 190-100 ECJ, -100 LR, -100 IGW. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to the airplanes certificated in any category, identified in paragraphs (c)(1) and (c)(2) of the AD. (1) EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes, equipped with outboard slat skew sensor part number (P/N) 1702286A or 1702288A. (2) EMBRAER Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200 STD, -200 LR, and -200 IGW airplanes, equipped with outboard slat skew sensor P/N 1702286A or 1702288A.

Unless already done, do the following actions. (1) At the applicable compliance time in paragraph (f)(1)(i) or (f)(1)(ii) of this AD: Perform an operational test (OPT) of any outboard slat skew sensor having P/N 1702286A or P/N 1702288A. If any outboard slat skew sensor fails the test, replace the sensor with a serviceable sensor before further flight. Do the actions using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Agência Nacional de Aviação Civil (ANAC) (or its delegated agent). (i) For Model ERJ 170 airplanes: Within 1,320 flight hours after the effective date of this AD. (ii) For Model ERJ 190 airplanes: Within 1,320 flight hours or 12 months after the effective date of this AD, whichever occurs first. Note 1: Guidance on performing the OPT required by paragraph (f)(1) of this AD can be found in Task 27-83-01-710-801-A, “Outboard Slat Skew Sensor—Operational Test,” dated October 28, 2008, of the Embraer 170/175 or 190 Aircraft Maintenance Manual (AMM). Note 2: For the purpose of this AD, an OPT is “A task to determine if an item is fulfilling its intended purpose. Since it is a failure-finding task, it does not require quantitative tolerances.” Note 3: For the purpose of this AD, a serviceable sensor is one that has passed the OPT required by paragraph (f)(1) of this AD. (2) Repeat the OPT required by paragraph (f)(1) of this AD thereafter at intervals not to exceed 1,320 flight hours. FAA AD Differences Note 4: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, 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: Kenny Kaulia, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2848; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. (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. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
