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.

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.
