Notice of Proposed Rulemaking

NPRM

Section 02: Regulatory Vocabulary

Definition

A formal public notice published by the FAA in the Federal Register that proposes a new regulation or an amendment to an existing regulation. An NPRM describes the proposed rule, its legal basis, the problem it addresses, and its expected impact. The NPRM opens a public comment period (typically 60-90 days) during which any person may submit comments, data, or arguments. The FAA must consider all comments before issuing a final rule. EASA's equivalent is the Notice of Proposed Amendment (NPA).
