Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes
Superseded. A later AD replaced this one: AD 2009-23-08. Comply with the one in force.
This AD applies to all 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, and -100 IGW airplanes; certificated in any category.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2007-06-53 that was sent previously to all known U.S. owners and operators of EMBRAER Model ERJ 170 and ERJ 190 airplanes by individual notices. This AD requires repetitively verifying the correct closure of the forward and aft cargo doors, inspecting the forward and aft cargo doors for interference between the lock handle and the aft edge liner assembly, repetitively inspecting the lateral roller fittings on the forward and aft cargo door frames for damage, and doing corrective actions if needed. This AD also requires reporting any signs of interference or damage to the manufacturer. This AD results from a report indicating that the aft cargo door opened in flight just after departure, and from a report indicating that an airplane was dispatched with an unsecured forward cargo door. We are issuing this AD to prevent a cargo door from opening during flight, which could lead to structural failure or loss of control.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
As of 24 hours after the effective date of this AD: 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 (g) of this AD.
Within 10 days after the effective date of this AD, do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD, in accordance with the Accomplishment Instructions of EMBRAER Alert Service Bulletin 170-52-A036 (for Model ERJ 170 airplanes) or 190-52-A018 (for Model ERJ 190 airplanes), both dated March 12, 2007, as applicable.
(1) Remove the roller fitting cover plate on the forward and aft cargo door frames.
(2) Perform a detailed inspection of the forward and aft cargo doors to detect signs of interference between the lock handle and the aft edge liner assembly. Then rework the aft edge liner assembly at the applicable time specified in paragraph (g)(2)(i) or (g)(2)(ii) of this AD.
(i) If any sign of interference is detected: Rework the assembly before further flight.
(ii) If no sign of interference is detected: Rework the assembly within 150 flight cycles after the inspection.
(3) Perform a detailed inspection for signs of damage of the lateral roller fitting on the forward and aft cargo door frames at the fuselage. If any damage is found, replace the lateral roller fitting before further flight with a new roller fitting having the same part number, in accordance with the applicable service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. 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 service information for the rework and roller fitting cover plate removal. Service Bulletins 170-50-0006 and 190-50-0006 are currently at Revision 01, dated March 13, 2007.
Repeat the inspection specified in paragraph (g)(3) of this AD at intervals not to exceed 150 flight cycles.
(i) At the applicable time specified in paragraph (i)(1) or (i)(2) of this AD: Send EMBRAER a report of any signs of interference or damage found during each inspection required by paragraphs (g)(2), (g)(3), and (h) of this AD. The report must include the inspection results, a description of any discrepancies found, the airplane serial number, and the number of landings and flight hours on the airplane. Send the report to EMBRAER, EFTC, AOG Structure Team; structure@embraer.com.br; fax +55 12 3927 6600, extension 0484. 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 contained in this AD and has assigned OMB Control Number 2120-0056.
(1) For any inspection done after the effective date of this AD: Within 10 days after the inspection.
(2) For any inspection done before the effective date of this AD: Within 10 days after the effective date of this AD.
As of the effective date of this AD: No person may install a roller fitting cover plate on the forward and aft cargo door frames on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
