REACH & Global Chemical Regulations

Pratt & Whitney continues to take a leadership role in the development of environmentally responsible products, services and operations.

Pratt & Whitney introduced the Green Engine Program in the 1990’s to focus our Design for Sustainability efforts, with the goal to minimize the use of Materials of Concern in Pratt & Whitney engine designs. This effort resulted in our latest family of engines being in the forefront of Green Engine technology in the aerospace industry.

Today, the Green Engine Program is part of a cross-functional team effort committed to complying with the European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation (EC 1907/2006) and other global regulations throughout the life cycle of our engines. We are deploying new tools to assist our business, suppliers and customers to comply with the requirements of this regulation and adapting strategies for future regulatory obligations.

In addition, Pratt & Whitney works in close cooperation with such organizations as the International Aerospace Environmental Group (IAEG®) and both US & EU Aerospace Associations (AIA & ASD) when aligning compliance with REACH requirements. Pratt & Whitney is adopting IAEG®’s aerospace and defense industry declarable substances list (AD-DSL) as a tool to identify use of regulated substances.



REACH Regulation Requirements and Guidance

Article 33 in the REACH regulation requires that safe use information be communicated for Substances of Very High Concern (SVHC) when an article contains SVHCs in a concentration above 0.1 percent weight by weight (w/w). Pratt & Whitney has to date identified the following SVHCs at greater than 0.1 percent w/w in articles:

CAS# Substance Name Safe Use Document
7440-43-9 Cadmium
142844-00-6* Aluminosilicate refractory ceramic fibres
7738-94-5 Chromic acid
1333-82-0 Chromium trioxide
13530-68-2 Dichromic acid
24613-89-6 Dichromium tris(chromate)
1317-36-8 Lead monoxide
10588-01-9
7789-12-0
Sodium dichromate
7789-06-2 Strontium chromate
12141-20-7 Trilead dioxide phosphonate

*REACH does not identify specific CAS numbers for Refractory Ceramic Fibres (RCFs). To date, P&W has identified use of at least one CAS number meeting the regulatory definition of an RCF. All actors in the supply chain are responsible for their own assessment for potential others.

REACH requires an Authorisation for continued use of Authorisation List SVHCs (Annex XIV) in the European Economic Area after their assigned sunset dates. Because certain SVHCs do not currently have suitable alternatives for use in all aerospace applications, UTC and Pratt & Whitney have worked with several industry consortia to create Authorisation requests. All actors in the aerospace industry supply chain are responsible for understanding and taking action on their obligations under REACH.
