EASA Approved Noise Levels

Article 6 of the Basic Regulation as amended by Commission Regulation (EU) No 2016/4 defines the "essential requirements for environmental protection" and requires that products, parts and appliances shall comply with the requirements contained in Annex 16 to the Chicago Convention.

Paragraph 21A.41 of the Part 21 Annex to Commission Regulation (EC) No 748/2012 as amended by Commission Regulation (EU) No 2016/5 states that the aircraft type-certificate and restricted type-certificate both include the type-certificate data sheet for noise (TCDSN).

The TCDSN documents an aircraft type's compliance with the applicable requirements for noise certification and records the associated EASA approved noise level(s).  The TCDSNs for aeroplanes and rotorcraft for which EASA has issued a type certificate can be accessed via the relevant hyperlinks to be found on the TCDS EASA website page (TCDS aircraft).

EASA has also determined the EASA approved noise levels for those products defined under Article 3 of Commission Regulation (EU) No 748/2012, the so called “transferred” products.  Databases of EASA approved noise levels for these transferred products, and aircraft modified via acoustically significant STCs, in addition to the noise levels approved for products for which EASA has issued a TC, have been prepared and are accessible from this page.

The EASA approved noise levels are the basis against which national authorities issue individual noise certificates (EASA Form 45 - Commission Regulation (EU) No 748/2012, L 224/64) to aircraft on their national registers according to the procedures of sub-Parts I of the Part 21 Annex to Commission Regulation (EC) No 748/2012.

Questions concerning the content of either the TCDSNs or databases, as well as the notification of any possible errors and omissions, should be addressed to EASA via noise [at] easa [dot] europa [dot] eu. To facilitate communication concerning errors and omissions please use the following forms:
