APPLICABILITY:

This Airworthiness Directive is applicable to all Embraer ERJ-170 aircraft models in

operation and equipped with low pressure check valves (LPCV) Hamilton SUlldstTalld part number (PIN)

CANCELLATION I REVISION:

T11is AD cancels and supersedes the AD No. 2005-09-03RI - Arndt 39-1126, dated

23 May 2006, and is being issued to change its required action, the compliance time and to include a

temlinating action.

REASON:

[t has been found the occurrence of an engine in-flight shutdm·vn caused by the LPCV

failing to close due to excessive wear, which leads to the concern that such fault may be present in both

engines of a given aircraft.

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.

REQUIRED ACTION:

Replacement of the right hand (RH) and left hand (LI-I) LPCVs; and revision of tlle

approved maintenance plan.

COMPLIANCE:

Required as indicated below, unless already accomplished.

(a) Within the next 100 flight hams (FJ:-I-)after 29 Sep. 2005, the effective date of the original issue of

this AD, on aircraft logging 3000 FH or above, replace the RH LPeV of PIN 1001447-3 by a new

one of same PIN. Repeat this replacement at intervals that do not exceed 3000 FH.

(b) Within the next 300 FH after 23 May 2006, the effective date of this revision 1 of AD, on aircraft

logging 3000 FH or above, replace the LH LPCV PIN 1001447-3 by a new one of same PIN. Repeat

this replacement at intervals that do not exceed 3000 FH.

(c) Replacement of LPCV PIN 1001447-3 by a new one beanng PIN 1001447-4 is considered a

temlinatlog action for the repetitive replacements required by items (a) and (b) above.

Cd) Within the next 180 days after the accomplishment of item (c) above, or before any LPCV PiN

1001447-4 installed reaches 3000 FH, whichever occurs first, revise the approved maintenance plan

to include the maintenance task No. 36-11-02-002 (Functional Check - Low Stage Bleed Check

Valve, Category 8), according to the Maintenance Review Board Report (MRBR) Revision 4 dated

31 May 2007, with the intervals established in that document, or its further revisions approved by

CONTINUATIONOF AD No.: 200S'()9'()3R2 - AMENDMENT 39·1208 PAGE No.: 2/2

(e) After the effective date of this revision 2 of AD, any LPCY PIN 1001447-3 that have accumulated

more than 3000 FH on models ERJ- J 70, or that have accumulated a total of FH equivalent to 3000

FH considering its utilization on models ERJ-170 and ERJ-190, cannot be fe-installed.

NOTE: To calculate the equivalent number of FH for a LPCV PIN 1001447-3 to be installed on aircraft

models ERJ-170, the FH accumulated in operation on aircraft models ERJ-190 must be

multiplied by a factor of2 (100%).

The detailed instructions and procedures to accomplish this AD are described in the

Embraer Service Bulletins Nos. 170-36-0004 original issue, or 170-36-0011 original issue, as applicable,

or respective fimher revisions approved by the ANAC.
