SUPPLEMENTARY INFORMATION:

Comments Invited

The FAA invites you to send any written relevant data, views, or arguments about AD 2024–05–05. Submit comments as instructed in AD 2024–05–05, Amendment 39–22696 (89 FR 18534, March 14, 2024).

Background

AD 2024–05–05 requires accomplishing a functional check of an affected part, replacing an affected part if necessary, and reporting the functional check results, and prohibits the installation of affected parts. That AD applies to all ATR—GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes.

Need for the Correction

As published, the docket number specified in the preamble and regulatory text of AD 2024–05–05 is incorrect. The correct docket number is FAA–2024–0459.

Related Service Information Under 1 CFR Part 51

EASA Emergency AD 2024–0044–E specifies the following procedures:

• Accomplishing a functional check of an affected part.
• Replacing an affected part with a serviceable part, if any discrepancy is detected during the functional check. (A discrepancy is any amount of air that flows through either connector of the right engine extinguishing system when compressed air is passed through either connector of the left engine extinguishing system, and vice versa.)

• Reporting inspection ( i.e., functional check) results to the airplane manufacturer.

• Prohibiting the installation of affected parts.

This material 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 an error in multiple locations in AD 2024–05–05 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, the FAA is publishing the entire rule in the Federal Register .

The effective date of this AD remains March 29, 2023.

Since this action only corrects the docket number for AD 2024–05–05, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has 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

Adoption of the Amendment

Accordingly, pursuant to the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
