FAA Proposes Stage 5 Noise Standards for New Aircraft
The FAA provides a longer compliance timeframe for aircraft weighing less than 121,254 pounds mtow.

The FAA is paving the way for new Stage 5 noise requirements that would align U.S. and international standards. It released a notice of proposed rulemaking (NPRM) late last week that would require companies submitting an application after Dec. 31, 2017, for a new aircraft weighing at least a 121,254 pounds mtow to meet Stage 5 requirements. Applicants for new aircraft weighing less than 121,254 pounds mtow must meet the Stage 5 standard after Dec. 31, 2020.
