BRAZILIAN AIRWORTHINESS DIRECTIVE

AD No.: 2012-07-01 Effective Date: 30 Jul. 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. 2012-07-01 - EMBRAER / 39-1356.

APPLICABILITY:

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

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

and, ERJ 170-200 SU airplanes; as identified in Embraer Service Bulletin (SB) 170-26-0011, 

revision 01, dated June 19th, 2012.

Not Applicable.

CANCELLATION / REVISION:

REASON:

It was found during an inspection of the cargo compartment fire extinguisher 

system that High Rate Discharge (HRD) bottle explosive cartridges were swapped between 

forward and aft cargo compartments. Additional investigation has also revealed the possibility of 

swapping between the electrical connectors of the HRD and Low Rate Discharge (LRD) bottles 

and a rotated installation of the HRD bottle. Such improper assembly of the fire extinguishing 

bottle may cause the extinguishing agent to be discharged toward the unselected cargo 

compartment rather than toward the cargo compartment with fire, resulting in an insufficient

concentration of fire extinguishing agent in the cargo compartment with fire, and consequent 

inability of the fire extinguishing system to suppress fire.

Since this condition may occur in other airplanes of the same type and affects 

flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance 

with these requirements in the indicated time limit.

Cargo Compartment Fire Extinguisher System – High and Low Rate Discharge 

Bottle inspection and relocation/replacement, if necessary.

REQUIRED ACTION:

Required as indicated below, unless already accomplished.

COMPLIANCE:

Low and High Rate Discharge bottles inspection and correction/replacement
