AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; correction.

SUMMARY:

The FAA is correcting airworthiness directive (AD) 2013-05-08 that published in the Federal Register. AD 2013-05-08 applies to all Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200 and A340-300 series airplanes. Two paragraphs of AD 2013-05-08 incorrectly specify flight control secondary computers (FCSCs), rather than flight control primary computers (FCPCs). This document corrects those errors. In all other respects, the original document remains the same.

DATES:

This final rule is effective August 29, 2013. The effective date for AD 2013-05-08, Amendment 39-17380 (78 FR 27015, May 9, 2013), remains June 13, 2013.
