Global Chemical Regulations And Materials Of Concern

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 (MOC) 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.

MATERIALS OF CONCERN

It is the policy of Pratt & Whitney to eliminate or reduce the use of MOC in the design, manufacture, assembly, disassembly, maintenance, repair, overhaul, operation and disposal of our products. The Pratt & Whitney MOC list identifies materials that are prohibited or restricted from use in Pratt & Whitney products. The list provides substance classifications in accordance with specification PWA 328 for use during the product design approval process. Material or process substance use declarations are also based on the MOC list, as applicable.

To meet customer and regulatory compliance requirements, Pratt & Whitney depends on suppliers to submit and update Material Declarations on request.  Pratt & Whitney requires design-responsible suppliers to meet the requirements of specification PWA 328 for new designs, and to respond to material declaration requests for existing designs using the Material Declaration form below:

Pratt & Whitney’s declaration form is updated periodically to meet business needs, and additional forms may be developed for different types of suppliers. It is Pratt & Whitney’s intent to request the minimum level of information required to meet business needs. Pratt & Whitney is supporting the use of the IPC-1754 Materials Declaration Standard as the basis for future materials declarations, which will enable suppliers to use a common declaration method when responding to Pratt & Whitney and other aerospace and defense customers.

REACH REGULATORY COMPLIANCE

Safe Use Communication

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:

Supplier Assessment

To evaluate business continuity and compliance risk in our supply chain, Pratt & Whitney periodically performs assessments of certain aspects of REACH at select suppliers. The assessment questionnaire is updated periodically to align with supply chain risk.

Authorisation

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.
