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 5,000 flight cycles after the effective date of this AD: Inspect the fasteners in bulkhead 1 of the left- and right-hand pylons for the presence of aluminum fasteners, in accordance with Part I of the Accomplishment Instructions of Embraer Service Bulletin 170-54-0007 or 190-54-0008, both dated December 21, 2007; as applicable. If no aluminum fastener is found, this AD requires no further action.
(2) If any aluminum fastener is found, before further flight after the inspection required by paragraph (f)(1) of this AD: Replace any aluminum fastener with a titanium fastener in accordance with Part II of the Accomplishment Instructions of Embraer Service Bulletin 170-54-0007 or 190-54-0008, both dated December 21, 2007; as applicable.
Note 1: 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.
