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 ofagiven aircraft.

Since this condition may occur in other airplanes of the same type and affects flight safety, acorrective action isrequired. Thus, sufficient reason exists torequest compliance with this AD inthe indicated time limit.

REQUIRED ACTION: Replacement of the right hand (RH) and left hand (LI-I)LPCVs; and revision of tlle approved maintenance plan.

(a) Within the next 100 flight hams (FJ:-I-)after 29 Sep. 2005, the effective date ofthe original issue of this AD, on aircraft logging 3000 FH or above, replace the RH LPeV of PIN 1001447-3 by anew one ofsame PIN. Repeat this replacement atintervals that donot exceed 3000 FH. (b) Within the next 300 FH after 23 May 2006, the effective date of this revision 1 ofAD, on aircraft logging 3000 FH orabove, replace the LH LPCV PIN 1001447-3 byanew one ofsame PIN. Repeat this replacement atintervals thatdonot exceed 3000 FH. (c) Replacement of LPCV PIN 1001447-3 by a new one beanng PIN 1001447-4 is considered a temlinatlog action fortherepetitive replacements required by items (a) and (b) above.

### PIN 1001447-3 that have accumulated more than 3000 FH on models ERJ-J70, or that have accumulated atotal of FH equivalent to 3000 FH considering itsutilization onmodels ERJ-170 and ERJ-190, cannot be fe-installed. NOTE: Tocalculate the equivalent number ofFH for aLPCV PIN 1001447-3 tobe installed on aircraft

models ERJ-170, the FH accumulated in operation on aircraft models ERJ-190 must be multiplied byafactor 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, orrespective fimher revisions approved bytheANAC.
