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

## BRAZILIAN AIRWORTHINESS DIRECTIVE **AD No.: 2011**  **- 05**  **- 02**  **Effective Date: 9**  **M ay**  **2011** The following Brazilian Airworthiness Directive (AD), issued by the Agência Nacional de Aviação Civil (ANAC) in accordance with p rovisions 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. 2011**  **- 05**  **- 02**  **- EMBRAER**  **/ 39**  **- 1335**  **. APPLICABILITY:**  This AD applies to Embraer S.A. models 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 and ERJ190
- 200 IGW airplanes in operation, all serial numbers.

**CANCELLATION / REVISION:** This AD cancels and supersedes AD 2010
- 01
- 02R1 and AD 2010
- 07
- 03 , and is being issued to incl ude a terminating action.

**REASON:** This AD results from the possibility of loss of automatic activation of the engine inlet ice protection system when flying in ice condition. Even thought the failure is announced by the caution messages “A
- I Eng 1 Fail” e “A
- I Eng 2 Fail”, if the engines inlet ice protection system is not manually activated, ice may accrete in the engine inlet and causes engine to shut down.

Also there is the possibility of right hand (RH) engine compressor to stall after the Auxiliary Powe

r Unit (APU) becomes the active bleed source for the left side, following left hand (LH) engine failure, under a condition where both engines are close to idle, the APU is running, and the APU bleed button is pushed in (automatic position).

Since these con ditions may occur in other airplanes of the same type and affect flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit.

**REQUIRED ACTION:** Replacement of the AMS Control ler Processor modules. **COMPLIANCE:** Required as indicated below, unless already accomplished. **Restatement of requirements of AD 2010 -**  **01 -**  **02R1** (a) For airplanes equipped with Air Management System (AMS) controller cards part number (P/N) 1001050
