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.

2. On page 31088, in the first column, in amendatory instruction 11 for § 34.25, add paragraph (d) to read as follows:
