Abstract
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2C11 (Regional Jet Series 550) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model C-600-2E25 (Regional Jet Series 1000) airplanes. As published, a portion of the initial compliance time for doing the new ram-air valve task specified in the regulatory text for certain airplanes is incorrect. This document corrects that error. In all other respects, the original document remains the same.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The FAA is correcting an airworthiness directive (AD) that was
published in the Federal Register. That AD applies to all MHI RJ
Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702)
airplanes, Model CL-600-2C11 (Regional Jet Series 550) airplanes, Model
CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24
(Regional Jet Series 900) airplanes, and Model C-600-2E25 (Regional Jet
Series 1000) airplanes. As published, a portion of the initial
compliance time for doing the new ram-air valve task specified in the
regulatory text for certain airplanes is incorrect. This document
corrects that error. In all other respects, the original document
remains the same.
DATES: This correction is effective April 28, 2023. The effective date
of AD 2023-06-06 remains April 28, 2023.

SUPPLEMENTARY INFORMATION:
Background
AD 2023-06-06, Amendment 39-22392 (88 FR 17682, March 24, 2023) (AD
2023-06-06), requires revising the existing maintenance or inspection
program, as applicable, to incorporate two aircraft maintenance manual
(AMM) tasks. That AD applies to all MHI RJ Aviation ULC Model CL-600-
2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2C11
(Regional Jet Series 550) airplanes, Model CL-600-2D15 (Regional Jet
Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900)
airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
Need for the Correction
As published, a portion of the initial compliance time specified in
paragraph (g)(1)(ii) of AD 2023-06-06 is incorrect. The initial
compliance time specified in paragraph (g)(1)(ii) of AD 2023-06-06 is
within 90 days after the effective date of this AD or before
accumulating 3,000 total flight hours, ``whichever occurs later.'' That
compliance time should be within 90 days after the effective date of
this AD or before accumulating 3,000 total flight hours, ``whichever
occurs first.'' This is the compliance time provided in Transport
Canada AD CF-2021-38R1, dated May 25, 2022, which the FAA intended to
match.
Correction of Publication
This document corrects an error 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 April 28, 2023.
Since this action only corrects a certain compliance time, it has
no adverse economic impact and imposes no additional unforeseen burden
on any person. Therefore, the FAA has determined that notice and public
procedures are unnecessary.

Adoption of the Amendment
0
Accordingly, pursuant to the authority delegated to me by the
Administrator,
[[Page 21901]]
the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part
39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2023-06-06 MHI RJ Aviation ULC (Type Certificate Previously Held by
Bombardier, Inc.): Amendment 39-22392; Docket No. FAA-2022-0679;
Project Identifier MCAI-2021-01213-T.
(a) Effective Date
This airworthiness directive (AD) is effective April 28, 2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all MHI RJ Aviation ULC airplanes,
certificated in any category, identified in paragraphs (c)(1)
through (5) of this AD.
(1) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702)
airplanes.
(2) Model CL-600-2C11 (Regional Jet Series 550) airplanes.
(3) Model CL-600-2D15 (Regional Jet Series 705) airplanes.

(5) Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
(d) Subject
Air Transport Association (ATA) of America Code: 21, Air
conditioning.
(e) Reason
This AD was prompted by a determination that the existing
maintenance or inspection program, as applicable, must be revised to
incorporate two aircraft maintenance manual (AMM) tasks. The FAA is
issuing this AD to address in-service reports of emergency ram air
valve part number (P/N) GG670-95019-1 stuck in closed or partially
open positions, which, if not corrected could result in a complete
loss of outside air supply, leading to an increase in flight deck
and cabin temperatures and a possible increased level of
contaminated air (carbon monoxide, carbon dioxide, or ozone).
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Maintenance or Inspection Program Revision
(1) Within 90 days after the effective date of this AD, revise
the existing maintenance or inspection program, as applicable, to
incorporate the information specified in figure 1 to the
introductory text of paragraph (g)(1) of this AD. The initial
compliance time for doing the task is at the applicable time
specified in paragraph (g)(1)(i) or (ii) of this AD.
