### AGÊNCIA NACIONAL DE AVIAÇÃO CIVIL **– BRAZIL**  

## BRAZILIAN AIRWORTHINESS DIRECTIVE **AD No.: 2006 -**  **11 -**  **01R6 Effective Date: 30 May 2011**  The following Brazilian Airworthiness Directive (AD), issued by the Agência Nacional de Aviação Civil (ANAC) in accordance wit h provisions of Chapter IV, Title III of Código Brasileiro de Aeronáutica - Law No. 7,565 dated 19 December 1986 - and Regulamento Brasileiro d a Aviação Civil (RB AC ) 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. 2**  **006 -**  **11 -**  **01R6 -**  **EMBRAER /**  **39 -**  **1337 .**  **APPLICABILITY:** This Airworthiness Directive applies to all Embraer model ERJ 190 - 100 STD , ERJ 190 - 100 LR, ERJ 190 - 100 IGW, ERJ 190 - 100 ECJ, ERJ 190 - 100 SR, ERJ 190 - 200 STD, ERJ 190 - 200 LR e ERJ 190 - 200 IGW, airplanes equipped with Hamilton Sundstrand Low Pressure Check Valve (LPCV) Part Numbers (P/N) 1001447 - 3 and/or 1001447 - 4.

**CANCELLATION / REVISION:**  This AD cancels and supersedes the AD No. 2006 - 11 - 01R5

– Amd 39 - 1300, dated 30 Jun. 2010, and is being issued to prohibit the installation, in ERJ - 190 airplanes, of LPCV P/N 1001447 - 4 previously installed in ERJ - 170 airplanes, unless the valve has been overhauled. This AD also defines the limit date after which the installation of LPCV P/N 1001447 - 4 is prohibited.

**REASON:** It has been found the occurrence of an engine in - flight shutdown at 20 September 2005, caused by the LPCV failure P/N 100144 7 - 3 with 3,900 Flight Hours (FH) installed on ERJ - 170. This valve failed open due excessive wear. At 23 Sep. 2010, it was found the occurrence of an engine shutdown on - ground, caused by the LPCV failure P/N 1001447 - 4 with 1,802 flight hours installed on ER J - 190 failed due low cycle fatigue. Since the behavior of a valve P/N 1001447 - 4 removed from ERJ 170 is unknown on ERJ - 190 and the P/N 1011447 - 4 is common between ERJ - 170 and ERJ - 190 airplane fleet, an action is necessary to prevent the installation, in ER J - 190 airplanes, of LPCVs P/N 1001447 - 4 previously installed in ERJ - 170 airplanes .

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 comp liance with this AD in the indicated time limit.

**REQUIRED ACTION:** Replacement of LPCVs of right (RH) and left (LH) engines; and revision of the approved maintenance plan; and to prohibit the installation, in ERJ - 190 airplanes, of LPCVs P/N 1001447 - 4 previo usly installed in ERJ - 170 airplanes, unless the valve has been overhauled; and to define a limit date after which the installation of LPCV P/N 1001447 - 4 is prohibited.

**COMPLIANCE:** Required as indicated below, unless already accomplished .**CONTINUATION OF AD**  **N o**  **.: 2006 -**  **11 -**  **01R6 /**  **39 -**  **1337 PAGE N**  **o .:**  **2 /**  **3**
