Preflight Verifications of Correct Door Closure (f) 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. Inspection for Interference and Damage (g) 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.

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.

This AD results from a report indicating that the aft cargo door of a Model ERJ 190 airplane opened in flight just after departure, and from a report indicating that a Model ERJ 170 airplane dispatched with an unsecured forward cargo door. The Federal Aviation Administration is issuing this AD to prevent a cargo door from opening during flight, which could lead to structural failure or loss of control.
