Airworthiness Directive · Amendment 39-18878 · Landing gear
Embraer S.A. Airplanes
This AD applies to Embraer S.A. Model EMB-120, EMB-120ER, EMB-120FC, EMB-120QC, and EMB-120RT airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD was prompted by changes to the airworthiness limitations, which add life-limited landing gear parts not previously identified. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new airworthiness limitations that add life limits for previously unidentified landing gear parts. We are issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, by incorporating the life-limited landing gear parts and the applicable safe-life limits identified in table 1 to paragraph (g) of this AD, as specified in EMB-120 Brasilia Maintenance Review Board (MRB) Report, Temporary Revision 28-1, dated May 17, 2016.

The initial compliance time for the replacement of affected parts is specified in paragraphs (h)(1) and (h)(2) of this AD. Replace affected parts with serviceable parts, in accordance with the Accomplishment Instructions of Embraer Alert Service Bulletin 120-32-A543, dated July 11, 2016.
(1) Before the applicable safe-life limit identified in table 1 to paragraph (g) of this AD, or within 90 days after the effective date of this AD, whichever occurs later.
(2) Within 90 days after the effective date of this AD for parts on which the current status is unknown.
