SUPPLEMENTARY INFORMATION:

On February 2, 2026, the “25-Hour Cockpit Voice Recorder (CVR) Requirement, New Aircraft Production” final rule (RIN 2120-AL92) was published in the Federal Register at 91 FR 4447. That final rule amended the recording time of cockpit voice recorders (CVRs) from the previously mandated 2 hours to 25 hours for all affected future manufactured aircraft. After publication, FAA discovered §§ 91.609, 125.227 and 135.151 contained the following typographical, grammatical, and formatting errors.

Corrections to 14 CFR 91.609

In § 91.609(i)(2)(i)(B), the text should read “type-certificated with” instead of “type-certificated for.”
In § 91.609(i)(2)(i)(C), the text should read “59,524 pounds or less.” rather than “59,524 pounds or less; or.”

Correction to 14 CFR 125.227

In § 125.227(h)(2)(i)(B), the text should read “more and type-certificated with” instead of “more type-certificated for.”

Corrections to 14 CFR 135.151

In § 135.151(g)(1)(iii)(A), paragraphs (a), (b), and (c) were incorrectly designated and should have been designated as § 135.151(g)(1)(iii)(A)(1), ( 2), and ( 3).
In § 135.151(g)(1)(iii)(A)(b), herein corrected as (2), the text should read “more and type-certificated with” instead of “more or type-certificated for.”
In § 135.151(g)(1)(iii)(A)(c), herein corrected as (3), the text should read “59,524 pounds or less.” instead of “59,524 pounds or less; or.”
Due to the incorrect designations in § 135.151(g)(1)(iii)(A), § 135.151(g)(1)(iii)(B) cross-referenced the incorrectly designated subsections. As such, in § 135.151(g)(1)(iii)(B) the text should read “requirements found in (g)(1)(iii)(A)(1), (g)(1)(iii)(A)( 2), and (g)(1)(iii)(A)( 3).”
In § 135.151(g)(2)(iii)(A), paragraphs (a), (b), and (c) were incorrectly designated and should have been designated as § 135.151(g)(2)(iii)(A)(1), ( 2), and ( 3).
In § 135.151(g)(2)(iii)(A)(b), herein corrected as (2), the text should read “or more and type-certificated with” instead of “or more with.”
Due to the incorrect designations in § 135.151(g)(2)(iii)(A), § 135.151(g)(2)(iii)(B) cross-referenced the incorrectly designated subsections. As such, in § 135.151(g)(2)(iii)(B) the ( printed page 25109) text should read “requirements found in (g)(2)(iii)(A)( 1), (g)(2)(iii)(A)( 2), and (g)(2)(iii)(A)( 3).”

This document corrects these various issues contained in the regulatory text.
