We are adopting a new airworthiness directive (AD) for Embraer S.A. Models EMB-500 and EMB-505 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 improperly tied castle nuts on the aileron, rudder, and elevator trim tab (or autotab) attachment bolts. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD following the Accomplishment Instructions in PHENOM by Embraer Alert Service Bulletin (SB) No.: 500-27-A026, Revision 1, dated October 6, 2017; or PHENOM by Embraer Alert SB No.: 505-27-A028, Revision 2, dated October 6, 2017, as applicable:
(1) Within the next 25 hours time in service (TIS) after May 15, 2018 (the effective date of this AD) or within the next 12 months after May 15, 2018 (the effective date of this AD), whichever occurs first, inspect the aileron trim tab, rudder trim tab, and elevator trim tab attachment points to make sure the cotter pin is installed on the castle nut of the attaching bolts.
(2) If any discrepancy is found during the inspection required in paragraph (f)(1) of this AD, before further flight, correct the discrepancy.
This AD allows credit for the actions required in paragraph (f) of this AD if done before the effective date of this AD following PHENOM by Embraer Alert SB No. 500-27-A026, original issue, dated September 29, 2017; PHENOM by Embraer Alert SB No. 505-27-A028, original issue, dated September 28, 2017; or PHENOM by Embraer Alert SB 505-27-A028, Revision 01, dated September 29, 2017; as applicable.
Although PHENOM by Embraer Alert SB No.: 500-27-A026, Revision 1, dated October 6, 2017; and PHENOM by Embraer Alert SB No.: 505-27-A028, Revision 2, dated October 6, 2017; specify to submit certain information to the manufacturer, this AD does not require that action.
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.
