2009-23-08 Empresa Brasileira de Aeronautica S.A. (EMBRAER): Amendment 39-16080. Docket No. FAA-2009-0687; Directorate Identifier 2009-NM-033-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December 17, 2009.
Affected ADs
(b) This AD supersedes AD 2007-06-53, Amendment 39-15035.
Applicability
(c) This AD applies to EMBRAER Model ERJ 170-100 LR, -100 STD, - 100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes; and ERJ 190-100 STD, -100 LR, -100 IGW, -200 LR, -200 STD, and -200 IGW airplanes; certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 52: Doors.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
It has been found the occurrence of two events of aircraft being dispatched with the cargo door opened without indication. In one of the events the aircraft took off with the cargo door opened.
The unsafe condition is a cargo door opening during flight, which could result in reduced structural integrity and consequent rapid decompression of the airplane. Required actions include repetitive inspections of the forward and aft cargo doors to detect signs of interference between the lock handle and the aft edge liner assembly and reworking the assembly; a one-time inspection for signs of damage of the lateral roller fitting on the forward and aft cargo door frames at the fuselage and replacement of the roller if necessary, and modification of the cargo door, which ends the repetitive inspections. After accomplishing the modification, the actions include incorporating information into the maintenance program to include the operational (OPC) and functional (FNC) checks of the forward and aft cargo doors and accomplishing repetitive OPC and FNC checks.
Compliance
(f) Required as indicated, unless accomplished previously.
Restatement of Requirements of AD 2007-06-53, With New Service Information
Preflight Verification of Correct Door Closure
(g) For Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes; and ERJ 190-100 STD, -100 LR, and -100 IGW airplanes: As of 24 hours after May 7, 2007 (the effective date of AD 2007-06-53), before each flight after closing the cargo doors, verify that the forward and aft cargo doors are closed flush with the fuselage skin, and that all 4 latched and locked indicators at the bottom of each door are green. Persons qualified to do this verification are mechanics and flightcrew members. If it cannot be verified that both doors are closed flush with the fuselage skin, and that all 4 latched and locked indicators at the bottom of each door are green, repair before further flight. Repeat the verification before every flight until accomplishment of the actions required by paragraph (h) of this AD.

Surface cleaning and elaborate procedures may be required.''
Note 2: Embraer Alert Service Bulletins 170-52-A036 and 190-52- A018 refer to Embraer Service Bulletins 170-50-0006 and 190-50-0006, respectively, as additional sources of guidance for the rework and roller fitting cover plate removal. Embraer Alert Service Bulletins 170-50-0006 and 190-50-0006 are currently at Revision 01, dated March 13, 2007.

Note 4: For the purposes of this AD, a functional check (FNC) is: ``A quantitative check to determine if one or more functions of an item perform within specified limits.''
Note 5: For the purposes of this AD, an operational check (OPC) 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.''
FAA AD Differences
Note 6: This AD differs from the MCAI and/or service information as follows: Where the MCAI includes a compliance time of ``after accomplishment of the modification'' for revising the maintenance program for Model ERJ-170 airplanes, we have determined that a compliance time of ``within 12months after the effective date of the AD or within 12 months after accomplishment of the modification, whichever occurs later'' is appropriate. This compliance time is equivalent to the compliance time required for Model ERJ-190 airplanes. The manufacturer and ANAC agree with this compliance time.
Other FAA AD Provisions
(l) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, 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, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; 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 aprincipal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. AMOCs approved previously in accordance with AD 2007-06-53, are approved as AMOCs for the corresponding provisions of paragraph (i) of 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.
