CAA-2006-11-004F

The aircraft owner or operator shall comply with Airworthiness Directives issued by the CAA or the aeronautics authority of the State of Design (SoD) of the aviation products, appliances and parts, and take all necessary actions thereto.

Issue Date: 2011/05/05

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.

Model Number: 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.

Subject: It has been found the occurrence of an engine in-flight shutdown at 20 September 2005, caused by the LPCV failure P/N 1001447-3 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 ERJ-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 ERJ-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 compliance with this AD in the indicated time limit.
