BRAZILIAN AIRWORTHINESS DIRECTIVE

AD No.: 2007-02-02R2 Effective Date: 17 Jul. 2009

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 de Homologação Aeronáutica (RBHA) 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. 2007-02-02R2 – EMBRAER - Amendment 39-1279.

APPLICABILITY:

This Airworthiness Directive (AD) applies to all Embraer ERJ 190 airplane models 

equipped with firewall hydraulic shutoff valve (FWSOV) part number (P/N) 975287-3 or 975287-5.

CANCELLATION / REVISION:

This AD cancels and supersedes the AD No. 2007-02-02R1 – Amdt 39-1197, dated 27 

Aug. 2007, and is being issued to remove the requirement to install the same FWSOV P/N in case of 

failure.

REASON:

Periodic operational check of the FWSOV, made during routine maintenance, has 

revealed that the failure rate of that component is significantly higher than expected. Such a dormant 

failure, when combined with further possible failures, such as engine fire, may lead to an unacceptable 

reduction of safety margins.

Since this condition affects flight safety, a corrective action is required. Thus, sufficient 

reason exists to request compliance with this AD in the indicated time limit.

REQUIRED ACTION:

Additional operational check of the firewall hydraulic shutoff valves..

COMPLIANCE:

Required as indicated below, unless already accomplished.

Within the next 600 flight hours after 27 Feb. 2007, the effective date of the original issue 

of this AD, and thereafter at intervals that do not exceed 600 flight hours, perform an operational check 

for proper operation of the FWSOV P/N 975287-3 or 975287-5, in accordance with Embraer Service 

Bulletin (SB) No. 190-29-0008 original issue, or further revisions approved by the ANAC. In case any 

FWSOV fails the operational check replace the faulty valve by another suitable FWSOV before the next 

flight.

NOTE 1: For the purpose of this AD, an operational check is: “A task to determine that an item is 

fulfilling its intended purpose. The check does not require quantitative tolerances. This is a 

failure finding task.”

NOTE 2: For the purpose of this AD, a suitable FWSOV is a firewall hydraulic shutoff valve P/N 

975287-3 or 975287-5 that has passed the operational check described in Embraer SB No. 

190-29-0008 or either the replacement of these valves by others bearing a new P/N.

The detailed instructions and procedures to accomplish this AD are described in the 

Embraer Service Bulletin No. 190-29-0008 original issue, or further revisions approved by the ANAC.

Record compliance with this AD in the applicable maintenance log book.
