AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; correction.

SUMMARY:

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain The Boeing Company Model 767-300 and 767-300F airplanes. Certain service information citations in the preamble and regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.

DATES:

This final rule is effective February 21, 2017.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 21, 2017 (82 FR 4778, January 17, 2017).

SUPPLEMENTARY INFORMATION:

Airworthiness Directive 2017-01-09, amendment 39-18776 (82 FR 4778, January 17, 2017), requires modification and installation of components in the main equipment center for certain Model 767-300 and 767-300F series airplanes. For certain airplanes, AD 2017-01-09 also requires modification, replacement, and installation of flight deck air relief system (FDARS) components.

Need for the Correction

As published, certain service information citations in the preamble and regulatory text were incorrect. The incorrectly specified citation in the preamble and regulatory text was Boeing Service Bulletin 767-27-0244, Revision 1, dated March 8, 2010 (“SB 767-27-0244, R1”); the correct citation is Boeing Service Bulletin 767-21-0244, Revision 1, dated March 8, 2010 (“SB 767-21-0244, R1”).

Related Service Information Under 1 CFR Part 51

We reviewed the following service information.

• Boeing Service Bulletin 767-21-0235, dated October 8, 2009; and Revision 1, dated July 29, 2011 (“SB 767-21-0235, R1”). The service information describes procedures for a relay installation and related wiring changes (which change (modify) the 3-way valve control logic for the cooling system for the flight deck display equipment on freighter airplanes).
• Boeing Service Bulletin 767-21-0244, Revision 1, dated March 8, 2010 (“SB 767-21-0244, R1”). The service information describes procedures for changing (modifying) the 3-way valve control logic and installing a cooling system for the flight deck display equipment.
• Boeing Alert Service Bulletin 767-21A0245, Revision 2, dated September 27, 2013 (“ASB 767-21A0245, R2”); and Boeing Alert Service Bulletin 767-21A0247, Revision 1, dated April 9, 2013 (“ASB 767-21A0247, R1”). The service information describes procedures for changing (modifying) the 3-way valve control logic and main cargo air distribution system (MCADS), and installing an FDARS. These documents are distinct since they apply to different airplane models.
• Boeing Alert Service Bulletin 767-21A0253, dated October 12, 2012. The service information describes procedures for replacing the existing duct, installing an FDARS, changing (modifying) the 3-way valve control logic, and installing a new altitude switch and pitot tube.
• Boeing Alert Service Bulletin 767-21A0254, dated June 7, 2013. The service information describes procedures for replacing the duct with a new duct; installing an FDARS (including the installation of mounting brackets, ducts, orifice, outlet valve, and screen); and activating the 3-way valve logic (including modification of the associated wiring and related actions).
• Boeing Service Bulletin 767-31-0073, dated October 12, 1995. The service information describes procedures for installing a maintenance data selection system for the engine indication and crew alerting system.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Correction of Publication

This document corrects errors in the citation of certain service information and correctly adds the AD as an amendment to 14 CFR 39.13. Although no other part of the preamble or regulatory information has been corrected, we are publishing the entire rule in the Federal Register.

The effective date of this AD remains February 21, 2017.

Since this action only corrects errors in the citation of certain service information, it has no adverse economic impact and imposes no additional burden on any person. Therefore, we have determined that notice and public procedures are unnecessary.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
• Aviation safety
• Incorporation by reference
• Safety
