Amendment No. 33-33
Abstract
This amendment clarifies aircraft engine vibration test requirements in the airworthiness standards. The clarification is in response to inquiries from applicants requesting FAA engine type certifications and aftermarket certifications, such as supplemental type certificates, parts manufacturing approvals, and repairs. We are revising the regulations to clarify that "engine surveys" require an engine test. The change is not substantive in nature, and will not impose any additional burden on any person.
