FAR 91.903 — Certificate of Waiver
FAR 91.903 explains how the FAA issues certificates of waiver allowing deviation from Part 91 rules when operations can still be conducted safely.
FAR 91.903 spells out how the FAA can let you legally fly outside the normal Part 91 rules through a certificate of waiver. This is the regulatory door that opens for things like airshows, banner tows, aerobatic boxes, and other special operations.
The key points:
- Authority to waive: The Administrator may issue a certificate of waiver allowing an operation to deviate from any rule listed in Subpart J (or those rules as modified by Subpart C of Part 194) — but only if the Administrator finds the proposed operation can be safely conducted under the waiver's terms.
- How to apply: Applications are made on a form and in a manner prescribed by the Administrator, and may be submitted to any FAA office.
- Effective period: Each waiver is effective as specified within the certificate itself — there's no fixed default duration.
Why it matters: as a pilot, you can't just decide to deviate from a rule because it's inconvenient. If your operation needs relief from a regulation, you must apply in advance, get FAA approval, and operate strictly within the waiver's stated terms.
