standards adopted by the Environmental Protection Agency (EPA), 
allowing manufacturers to certificate engines to the new nvPM emissions 
standards in the United States and fulfilling the statutory obligations 
of the FAA under the Clean Air Act. This document corrects errors in 
the preamble and regulatory text of that document.

Background

    On April 24, 2024, the FAA published a final rule titled ``Control 
of Non-Volatile Particulate Matter From Aircraft Engines: Emission 
Standards and Test Procedures'' (89 FR 31078). That document adopts 
standards for measuring non-volatile particulate matter nvPM exhaust 
emissions from aircraft engines. With this rulemaking, the FAA 
implements the nvPM emissions standards adopted by the EPA, allowing 
manufacturers to certificate engines to the new nvPM emissions 
standards in the United States and fulfilling the statutory obligations 
of the FAA under the Clean Air Act. After publishing the final rule, 
the FAA became aware that certain information in the preamble and 
regulatory text sections regarding compliance, were inadvertently 
omitted. This document corrects errors in the preamble and regulatory 
text of that document.

Correction

part 34 without interruption to their manufacturing or delivery 
process, manufacturers will have 90 days to comply with this rule after 
the rule becomes effective.'' after the sentence ``This date is 
consistent with the effective date of the EPA final rule that adopted 
these standards.''
