ACTION: Final rule; correction.
AGENCY:
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

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.

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
