Integration of Powered-Lift: Pilot Certification and Operations; Miscellaneous Amendments Related to Rotorcraft and Airplanes; Correction

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

ACTION: Final rule; correction.

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

SUMMARY: On November 21, 2024, the Federal Aviation Administration (FAA) published a final rule titled ``Integration of Powered-Lift: Pilot Certification and Operations; Miscellaneous Amendments Related to Rotorcraft and Airplanes'' (RIN 2120-AL72). That final rule inadvertently duplicated two tables in the regulatory text of the Special Federal

[[Page 216]]

Aviation Regulation for powered-lift. This correction removes the duplicates. Additionally, the FAA inadvertently cited an incorrect paragraph in the Training center instructor eligibility requirements section of the Code of Federal Regulations. This correction corrects the paragraph reference.

DATES: This correction is effective January 21, 2025.

SUPPLEMENTARY INFORMATION: On November 21, 2024, the ``Integration of Powered-Lift: Pilot Certification and Operations'' final rule (RIN 2120-AL72) published in the Federal Register at 89 FR 92296. After publication, the FAA discovered that two tables had been inadvertently duplicated in the regulatory text of part 194, specifically table 1 to Sec. 194.302 and table 1 to Sec. 194.306. These two tables detail the provisions under parts 91 and 135 applicable to powered-lift, respectively. The first instance of each table includes revisions made prior to the publication of this rule while the second instance is the outdated and incorrect table. These revisions include adding the phrase ``of this chapter,'' where appropriate, and removing redundant section heading citations. This document corrects those tables by removing the incorrect text from each section. Additionally, the FAA inadvertently incorrectly cited a paragraph in Sec. 142.47(a)(5)(iv). The FAA had intended to cite paragraph (a)(5)(i) but instead cited Sec. 142.47(a)(i). This document corrects that citation.

Corrections

In FR 2024-24886, published in the Federal Register of November 21, 2024, at 89 FR 92296, make the following corrections:

Sec. 142.47 [Corrected]

0 1. On page 92489, in the first column, in Sec. 142.47, in paragraph (a)(5)(iv) introductory text, ``(a)(i)'' is corrected to read ``(a)(5)(i)''.

0 2. Beginning on page 92499, table 1 to Sec. 194.302 is corrected to read as follows:
