91-86 - Guidance on Carrying Noise Certification Documents On Board Aircraft Operating Outside the United States
- Date Issued

a. The Federal Aviation Administration (FAA) is amending its operating rules to require U.S. operators flying outside the United States to carry aircraft noise certification information on board the aircraft.
b. This Advisory Circular (AC) provides guidance to affected U.S. operators that operate aircraft outside the United States with aircraft that were never required to be noise certified. If you have such an aircraft, this AC outlines the noise certification requirement dates so you can confirm that your aircraft indeed pre-dates the requirements and should be considered acceptable. We use the term “grandfathered” for these aircraft. We strongly recommend operators of such aircraft to use the FAA form in Appendix 1 that includes a grandfather clause.
