(EMBRAER) Model EMB-135 Airplanes and Model EMB-145, -145ER, -145MR, -
145LR, -145XR, -145MP, and -145EP Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting a typographical error in an existing 
airworthiness directive (AD) that was published in the Federal Register 
on December 5, 2005 (70 FR 72363). The error resulted in the citation 
of incorrect part numbers. This AD applies to certain EMBRAER Model 
EMB-135 airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -
145MP, and -145EP airplanes. This AD requires repetitive inspections of 
the spring cartridges of the elevator gust lock system to determine if 
the lock washer projection correctly fits the slots in the cartridge 
flange, and corrective action if necessary, for certain airplanes. This 
AD also requires final terminating action for all affected airplanes.

DATES: Effective January 9, 2006.

ADDRESSES: The AD docket contains the proposed AD, comments, and any 
final disposition. You may examine the AD docket on the Internet at 
http://dms.dot.gov, or in person at the Docket Management Facility 
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S. 
Department of Transportation, 400 Seventh Street, SW., Room PL-401, 
Washington, DC. This docket number is FAA-2005-22033; the directorate 
identifier for this docket is 2004-NM-218-AD.

SUPPLEMENTARY INFORMATION: On November 18, 2005, the FAA issued AD 
2005-24-11, amendment 39-14391 (70 FR 72363, December 5, 2005), for 
certain EMBRAER Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR 
airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, 
and -145EP airplanes. That AD requires repetitive inspections of the 
spring cartridges of the elevator gust lock system to determine if the 
lock washer projection correctly fits the slots in the cartridge 
flange, and corrective action if necessary. That AD also requires final 
terminating action for all affected airplanes.
    On December 23, 2005, we issued a correction to AD 2005-24-11, (71 
FR 231, January 4, 2006), which corrected the reference to the 
effective date of Brazilian airworthiness directive 2003-01-03R1.
    As published, AD 2005-24-11 incorrectly cited the part numbers (P/
Ns) of the spring cartridges in several places as P/N KDP2611 and P/N 
KDP4235. Those P/Ns do not exist. The correct P/Ns should be KPD2611 
and KPD4235.
    No other part of the regulatory information has been changed; 
therefore, the final rule is not republished in the Federal Register.
    The effective date of this AD remains January 9, 2006.
