BRAZILIAN AIRWORTHINESS DIRECTIVE

AD No.: 2012-10-01 Effective Date: 29 Oct. 2012

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. 2012-10-01 – EMBRAER S.A. / 39-1362.

This Airworthiness Directive (AD) applies to Embraer SA 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; all serial numbers.

APPLICABILITY:

Note 1: This AD requires revisions to certain operator maintenance documents to include new 

inspections tasks or modification of existing ones and its respective thresholds and intervals. 

Compliance with these inspections is required by “Regulamento Brasileiro de Homologação 

Aeronáutica” - 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 described inspections. In this situation, to comply with RBHA 91.403(c), the operator must 

request approval for an alternative method of compliance. The request should include a 

description of changes to the required inspections that will ensure the continued operational 

safety of the airplane. An alternative method of compliance or adjustment of the compliance time 

that provides an acceptable level of safety may be used if approved by the Manager, Product 

Certification Branch (GGCP).

This AD cancels and supersedes AD 2011-04-01 / 39-1333, dated May 5th, 2011, 

and is being issued to include additional actions.

CANCELLATION / REVISION:

This AD results from a new revision to the Airworthiness Limitations Section 

(ALS) of Embraer ERJ 170 Maintenance Review Board Report (MRBR 1621), to include new or 

modification of the current tasks and its respective thresholds and intervals. Failure to inspect 

these structural components, according to the new or revised tasks, thresholds and intervals, 

could prevent a timely detection of fatigue cracking. These cracks, if not properly addressed, 

could adversely affect the structural integrity of the airplane.
