Airworthiness Directives; Airbus Airplanes

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.

SUPPLEMENTARY INFORMATION:

Airworthiness Directive (AD) 2013-05-08, Amendment 39-17380 (78 FR 27015, May 9, 2013), currently requires, depending on airplane configuration, modifying three flight control primary computers (FCPCs); modifying two flight control secondary computers (FCSCs); revising the airplane flight manual (AFM) to include certain information; replacing certain O-rings; and checking part number and replacing certain O-ring seals if needed.

As published, AD 2013-05-08, Amendment 39-17380 (78 FR 27015, May 9, 2013), currently includes typographical errors in paragraphs (p)(4) and (p)(5) of the AD, which specify FCSCs, instead of flight control primary computers FCPCs.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register.

The effective date of AD 2013-05-08, Amendment 39-17380 (78 FR 27015, May 9, 2013), remains June 13, 2013.
