AeroPARTS Plus provides original certification (or copies thereof) for all parts and supplies sold. We also provide our certificate of conformance statement (signed) on our invoices.
Supplies such as disposable brushes are not a certified item. They are not affixed to an aircraft in any way, shape or form. Whereas something like Tri-Flow Lubricant is sprayed on an aircraft therefore it does come with certification.
Exception to the rule is aviation oils and greases. We do not provide certification from the manufacturer but we do provide our C of C statement on our invoices. We can request certificates of analysis from the manufacturers if absolutely needed, by request only.
Any vendor questionnaire survey's can be emailed to firstname.lastname@example.org for completion.
