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; corrected March 26, 2024 (89 FR 20849)) (AD 2024-05-05).

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 effective, incorporation by reference approval, and comment submittal dates specified in the preamble of the preceding correction to AD 2024-05-05 are incorrect. The correct effective and incorporation by reference approval date is March 29, 2024. The correct date for submitting comments is April 29, 2024.

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 errors in the preceding correction to 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, 2024.

Since this action only corrects the preceding correction 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.
