Inspection Programs for Single-Engine Turbine-Powered Airplanes 
and Unmanned Aircraft; and Miscellaneous Maintenance-Related Updates; 
Correction

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM); correction; extension of 
comment period.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an NPRM published on January 31, 2024. 
In that document, the FAA proposed to amend its regulations to revise 
certain aircraft maintenance inspection rules for small, corporate-
sized, and unmanned aircraft. This document corrects errors in the 
preamble of that document.

DATES: The comment period for the proposed rule published January 31, 
2024, at 89 FR 6056, is extended. The comment period originally 
scheduled to close on April 1, 2024, is extended to close on May 1, 
2024.

SUPPLEMENTARY INFORMATION:

Background

    On January 31, 2024, the FAA published an NPRM titled, ``Inspection 
Programs for Single-Engine Turbine-Powered Airplanes and Unmanned 
Aircraft; and Miscellaneous Maintenance-Related Updates'' (89 FR 6056).
    In that NPRM, the FAA proposed to amend its regulations to revise 
certain

[[Page 19776]]

aircraft maintenance inspection rules for small, corporate-sized, and 
unmanned aircraft. The proposed changes include additional inspection 
program options for owners of single-engine turbine-powered airplanes 
and unmanned aircraft, relaxed mechanical reliability reporting 
requirements for part 91, subpart K aircraft, and several changes to 
clarify and simplify various maintenance-related regulations. These 
proposed amendments would relieve aircraft owners, operators, 
maintenance providers, and the FAA. The proposed amendments would 
provide greater flexibility for aircraft maintenance, standardized 
reporting requirements, and provide clarification of various 
maintenance-related regulations.

Extension of the Comment Period

    When the NPRM published on January 31, 2024, the comment period was 
scheduled to close on April 1, 2024. The FAA recognizes that the NPRM 
had incorrect information for approximately thirty (30) days and that 
the Preliminary Regulatory Impact Analysis that supports the NPRM had 
not been placed on the docket. The FAA has placed the Preliminary 
Regulatory Impact Analysis in the docket (FAA-2024-0025) and it is now 
available for review and comment. Based on this, the FAA has determined 
that it is appropriate to extend the comment period to May 1, 2024.
    After publishing the NPRM, the FAA became aware that certain 
information in the preamble, specifically in the Regulatory Notices and 
Analyses section, was incorrect. This document corrects those errors.

Correction

    In FR Doc. 2024-00763, beginning on page 6067 in the Federal 
Register of January 31, 2024, make the following corrections:
    1. On page 6607, in the sentence in the Summary of Benefits and 
Costs section in the third column correct ``Table 1 below presents a 
summary of estimated costs and cost savings for this proposal's manned 
aircraft maintenance programs over a 10-year time period'' to read 
``Table 3 below presents a summary of estimated costs and cost savings 
for this proposal's manned aircraft maintenance programs over a 10-year 
time period.''
    2. On page 6067, in the second to last column to the right in Table 
3--Summary of Costs and Cost Savings correct ``Annualized net cost 
savings 7%--$7,372,660'' to read ``Annualized net cost savings 7%--
$7,411,916.''
    3. On page 6067, in the last column to the right of Table 3--
Summary of Cost and Cost Savings correct ``Annualized net cost savings 
3%--$7,392,755'' to read ``Annualized net cost savings 3%--
$7,418,122.''
    4. On page 6068, in the sentence in the Costs and Cost Savings 
section in the third column correct ``Table 2 presents undiscounted 
cost savings, costs, net costs, discounted net cost savings, and 
annualized cost savings based on only one manufacturer offering its 
recommended inspection program'' to read ``Table 4 presents 
undiscounted cost savings, costs, net costs, discounted net cost 
savings, and annualized cost savings based on only one manufacturer 
offering its recommended inspection program.''
    5. On page 6068, in the sentences starting at the bottom of the 
second column correct ``For Year 1 in Table 3, using 2022 forecast 
estimates, the annual potential cost savings of the proposed rule would 
be $38,652,509 [$7,974 (estimated cost savings per aircraft) x 4,847 
(estimated single turboprops)]. In the remaining years in the 10-year 
period of analysis in Table 3, annual potential cost savings are 
calculated in the same manner as in Year 1 by multiplying $7,974 cost 
savings per aircraft with the number of forecasted aircrafts'' to read 
``For Year 1 in Table 5, using 2022 forecast estimates, the annual 
potential cost savings of the proposed rule would be $38,652,509 
[$7,974 (estimated cost savings per aircraft) x 4,847 (estimated single 
turboprops)]. In the remaining years in the 10-year period of analysis 
in Table 5, annual potential cost savings are calculated in the same 
manner as in Year 1 by multiplying $7,974 cost savings per aircraft 
with the number of forecasted aircrafts.''
