We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 500 flight hours after the effective date of this AD, perform a general visual inspection on the left-hand bulkhead blowout panel of both the forward and aft cargo compartments to determine whether the pressure equalization valves, part number (P/N) 120-48865-003, are installed. If both pressure equalization valves are installed in their respective blowout panels, no additional action is required by this AD.
(2) If any valve is not installed, within 700 flight hours after the effective date of this AD, install valve P/N 120-48865-003, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 170-21-0032 or 190-21-0019, both dated August 10, 2007; as applicable.
Note 1: For the purpose of this AD, a general visual inspection (GVI) is: “A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or irregularity. This level of inspection is made from within touching distance, unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight or drop-light, and may require removal or opening of access panels or doors. Stands, ladders or platforms may be required to gain proximity to the area being checked.”
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
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.
