The following Brazilian Airworthiness Directive (AD), issued by the Agência Nacional de Aviação Civil 

(ANAC) in accordance with provisions of Chapter IV, Title III of Código Brasileiro de Aeronáutica - Law No. 

7,565 dated 19 December 1986 - and Regulamento Brasileiro da Aviação Civil (RBAC) 39, applies to all aircraft 

registered in the Registro Aeronáutico Brasileiro. No person may operate an aircraft to which this AD applies, 

unless it has previously complied with the requirements established herein.

AD No. 2015-05-02 – EMBRAER S.A. / 39-1394.

APPLICABILITY:

This Airworthiness Directive (AD) applies to Embraer S.A. model ERJ 170-100 LR, ERJ 

170-100 SE, ERJ 170-100 STD, ERJ 170-100 SU, ERJ 170-200 LR, ERJ 170-200 STD and ERJ 170-200 

SU airplanes with manufacturer serial number 17000002, 17000004 through 17000013, and 17000015 

through 17000453, inclusive.

Note (1): Airplanes with an original airworthiness certificate or original export certificate 

of airworthiness issued on or after February 23, 2015 must comply with the airworthiness limitations 

specified as part of the airworthiness certification of those airplanes, or in accordance with operations 

specifications approved under “Regulamento Brasileiro da Aviação Civil” (RBAC) 121 or 135, or an 

inspection program approved under paragraph 91.409(e) of “Regulamento Brasileiro de Homologação 

Aeronáutica” (RBHA) 91.

Note (2): This AD requires revisions to certain operator maintenance documents to include 

new inspections or modification to the existing ones and its respective thresholds and intervals. Compliance 

with these inspections is required by RBHA 91.403(c). For airplanes that have been previously modified, 

altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish 

the inspections described in the revisions. In this situation, to comply with RBHA 91.403(c), the operator 

must request approval for an alternative method of compliance according to paragraph (c) of this AD. The 

request should include a description of changes to the required inspections that will ensure the continued 

damage tolerance of the affected structure.

CANCELLATION / REVISION:

This AD supersedes AD 2012-10-01 / 39-1362.

REASON:

This AD was prompted by a new revision to the airworthiness limitations of the 

Maintenance Review Board Report. This AD is being issued to ensure that fatigue cracking of various 

principal structural elements is detected and corrected; such fatigue cracking could adversely affect the 

structural integrity of these airplanes.

REQUIRED ACTION:

This AD requires revisions to certain operator maintenance documents to include new 

inspections.

COMPLIANCE:

Required as indicated below, unless already accomplished.
