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 
R[eacute]gional 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.

[[Page 20850]]

    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.

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:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Corrected]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

39-22696; Docket No. FAA-2024-0459; Project Identifier MCAI-2024-

(a) Effective Date

    This airworthiness directive (AD) is effective March 29, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all ATR--GIE Avions de Transport 
R[eacute]gional airplanes specified in paragraphs (c)(1) and (2) of 
this AD, certificated in any category.
    (1) Model ATR42-200, -300, -320, and -500 airplanes.

(e) Unsafe Condition

    This AD was prompted by a report of incorrect marking and 
assembly of the two-way valves for the left- and right-hand engine 
fire extinguishing systems. The FAA is issuing this AD to address 
inoperative two-way valves in both engine fire extinguishing 
systems. This condition, if not addressed, could lead to reduced 
performance of the engine fire extinguishing system, which could 
result in loss of control of the airplane.

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all

0044-E).

(h) Exceptions to EASA AD 2024-0044-E

    (1) Where EASA AD 2024-0044-E refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Paragraph (4) of EASA AD 2024-0044-E specifies to report 
inspection results to ATR--GIE Avions de Transport R[eacute]gional 
within a certain compliance time. For this AD, report inspection 
(i.e., functional check) results at the applicable time specified in 
paragraph (h)(2)(i) or (ii) of this AD.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) If the inspection was done before the effective date of 
this AD: Submit the report within 30 days after the effective date
