APPLICABILITY: I

This Airworthiness Directive is applicable to Embraer model ERJ 190-100 STD, ERJ

190-100 LR, ERJ 190-100 lOW, ERJ 190-100 ECJ, E~J 190-100 SR, ERJ 190-200 STD, ERJ 190-200

CANCELLATION f RI:VISION:

Not applicable.

REASON:

It has been found the possibility of right hand (RH) engine compressor stall after the

Auxiliary Power Unit (APU) becomes the active bleed source for the left side.

The most critical condition identified is:

- Both engines dose to idle (e.g.: descent phase); and

- APU running; and

- APU bleed button pushed in.

In this condition, if the left hand (UI) engine fails, the APU bleed valve and the crossbleed valve may be both in the open position for a few1seconds, what may lead to a backpressure in RH

engine depcnding on APU bleed pressurc_ Such backpressure may cause an RH engine compressor stall,

culminating in a dual engine failure. I

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

reason exists to request compliance with this AD.

REQUIRED ACTION:

Revision of the approved Airplane Fligl'it Manual (AFM).

COMPLIANCE: I

Required as indicated below, unless already accomplished.

Within 10 days after the effective date of this AD, revise the Limitation Section of the

AFM 10 include the information in the EMBRAER Operational Bulletin (OB) 170-001/09 Revision 01,

dated Feb 10,2010.

NOTE 1: The action required by this AD may be done by insening a copy of the OB

specified by this AD into the applicable AFM.

NOT _: The limitation specified by this AD is considered an intenm solution u 1 a

final action is identified, at which time the ANA may conSl er e· nee 0 a further rulemaking.

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