De Havilland Canada Dash 8-400 certified by the FAA and EASA to the most stringent noise emission standards

De Havilland Aircraft of Canada issued this statement:

  • The FAA and EASA approvals follow the approval by Transport Canada in 2020 that established the Dash 8-400 turboprop as the first regional aircraft and the only turboprop to meet ICAO Chapter 14 requirements
  • As the aviation industry works to reduce the environmental impact of commercial aircraft, the Transport Canada, FAA and EASA approvals are a testament to the Dash 8-400 aircraft’s advanced design and position it well ahead of other regional jets and turboprops in delivering low community noise during take-off and landing
  • Operators globally will benefit from these approvals by not having to re-fleet or re-engine in order to meet the industry’s most stringent noise reduction requirements

De Havilland Aircraft of Canada Limited has announced that the Federal Aviation Administration (FAA) and the European Aviation Safety Agency (EASA) have issued approvals for the Dash 8-400 turboprop aircraft as having met the most stringent noise emission standards. The aircraft is therefore certified to Stage 5 standards set by the FAA and certified by EASA as having met ICAO Chapter 14 standards. The Dash 8-400 aircraft was the first propeller-driven aircraft, and also the first regional aircraft in the world, to meet ICAO Chapter 14 standards when it was certified by Transport Canada in 2020.

Featuring quiet, swept, six-bladed Dowty propellers on Pratt & Whitney Canada PW150A engines, the Dash 8-400 aircraft has once again proven to be an environmentally advanced design. Not only is it quiet on the outside, it is also quiet inside the cabin. In order to further boost the comfort for passengers, the Dash 8-400 aircraft is engineered with a newly improved, proprietary Active Noise and Vibration Suppression (ANVS) system that effectively reduces the propeller noise level inside the aircraft to maximize cabin comfort. The Dash 8-400 aircraft has been acoustically engineered to mitigate the detrimental effects of aircraft noise on human health – inside and out, on the ground and in the sky.

De Havilland Canada continues to make future-oriented investments to enhance the Company’s competitiveness and ensure that Dash 8 Series aircraft remain at the forefront of the regional aircraft market.
