Airworthiness Directive 2013-11-17
recurringAirworthiness Directives; Embraer S.A. Airplanes
What this AD requires
We are superseding airworthiness directive (AD) 2010-14-14 that applies to certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. AD 2010-14-14 currently requires, for certain airplanes, repetitively replacing the low-stage check valve and associated seals of the right hand (RH) engine's engine bleed system with a new check valve and new seals, replacing the low pressure check valves (LPCVs), and revising the maintenance program. For certain other airplanes, AD 2010-14-14 requires replacing a certain low-stage check valve with an improved low-stage check valve. For certain airplanes, this new AD adds replacing certain LPCVs of the left hand (LH) and RH engines, which would be an option for other airplanes. This AD was prompted by reports of uncommanded engine shutdowns on both Model ERJ 170 and ERJ 190 airplanes due to excessive wear and failure of LPCVs having certain part numbers. We are issuing this AD to prevent the possibility of a dual engine in-flight shutdown due to LPCV failure.
Which aircraft AD 2013-11-17 applies to
Applies only to airplanes having Hamilton Sundstrand low pressure check valve (LPCV) P/N 1001447-3 or 1001447-4 installed. Model list: ERJ 170-100 LR, -100 STD, -100 SE, -100 SU; ERJ 170-200 LR, -200 SU, -200 STD; ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW; ERJ 190-200 STD, -200 LR, -200 IGW.
Whether AD 2013-11-17 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
