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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Before the accumulation of 20,000 flight cycles, do a detailed inspection for signs of drill marks at the left and right lower ring region of the rear pressure bulkhead between the circumferential splice joint and rear skin between stringers 12 and 13, in accordance with EMBRAER Service Bulletin 170-53-0082 or 190-53-0042, both Revision 01, both dated April 28, 2010, as applicable. If drill marks are found, repair before further flight, in accordance with EMBRAER Service Bulletin 170-53-0082 or 190-53-0042, both Revision 01, both dated April 28, 2010, as applicable.
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: This AD differs from the MCAI and/or service information as follows: Although EMBRAER Service Bulletins 170-53-0082 and 190-53-0042, both Revision 01, both dated April 28, 2010, specify doing a general visual inspection, this AD requires doing a detailed inspection.
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.
