2009-05-06: Flap system

2009-05-06 Empresa Brasileira de Aeronautica S.A. (EMBRAER): Amendment 39-15830; Docket No. FAA-2009-0150; Directorate Identifier 2009-CE-010-AD. \n\nEffective Date \n\n\t(a) This airworthiness directive (AD) becomes effective February 27, 2009. \n\nAffected ADs \n\n\t(b) None. \n\nApplicability \n\n\t(c) This AD applies to Models EMB-500 airplanes, all serial numbers, equipped with the stall warning computer part number (P/N) C100106-1, certificated in any category. \n\nSubject \n\n\t(d) Air Transport Association of America (ATA) Code 27: Flight Controls. \n\nReason \n\n\t(e) The mandatory continuing airworthiness information (MCAI) states: There is a possibility that during a go around procedure with a flap system failed the stall warning and the stick pusher triggering angles are anticipated reducing the margin between the real angle of attack and the stick pusher triggering angle. If the stick pusher is activated at a low altitude the pilot may be not able to recover the airplane control. Since this condition affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this EAD in the indicated time limit without prior notice. \n\nActions and Compliance \n\n\t(f) Unless already done, before further flight, incorporate into the airplane flight manual (AFM) the following procedures and limitations section revisions. You may insert a copy of this AD into the appropriate sections of the AFM to comply with the requirements of this AD. \n\t(1) Revise the AFM by adding Figure 1 of this AD to the Limitations section 2.30.\n\n\n\n\n\t(2) Replace the GO-AROUND procedure in AFM Section 3-03, page 2, with the procedure in Figure 2 of this AD. \n\n\n\n\t(3) Replace the ONE ENGINE INOPERATIVE PROCEDURE APPROACH AND LANDING procedure in AFM Section 4-01, page 17, with the procedure in Figure 3 of this AD. \n\n\n\n\n\t(4) Revise AFM Section 5-02 by adding the statement in Figure 4 of this AD. \n\n\n\n\t(5) Replace the AFM performance tables (ANTI-ICE OFF) in Section 5-20, pages 2 and 3, with the table in Figure 5 of this AD. \n\n\n\n\t(6) Replace the AFM performance tables (ANTI-ICE OFF) in Section 5-25, pages 2 and 3, with the table in Figure 6 of this AD. \n\n\n\n\n\tNote 1: The above limitation and procedures are considered an interim solution until a final action is identified, at which time AG(Ecirc)NCIA NACIONAL DE AVIACAO CIVIL--BRAZIL (ANAC) and the FAA may consider further AD action. \n\n\tNote 2: Operation in icing conditions is not affected by the above limitations and procedures. \n\n\tFAA AD Differences \n\n\tNote 3: This AD differs from the MCAI and/or service information as follows: No differences. \n\nOther FAA AD Provisions \n\n\t(g) The following provisions also apply to this AD: \n\t(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. 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. \n\t(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. \n\t(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. \n\nRelated Information \n\n\t(h) Refer to MCAI ANAC, EAD No.: 2009-02-04, dated February 13, 2009.
