Section 107.77(c) starts a 30-day clock when the holder of a remote pilot certificate changes a permanent mailing address. After 30 days from that date, the holder may not exercise the privileges of the certificate unless the FAA has been notified. Notice goes by letter to the FAA Airman Certification Branch, P.O. Box 25082, Oklahoma City, OK 73125, or through the FAA website at www.faa.gov. Give the new permanent mailing address. If that address includes a post office box, also give the current residential address.
The practice items tied to this page are not all address items. One is about an expired aircraft registration. One is about who may register a small unmanned aircraft when the owner is 12. One is about a Remote ID letter of authorization. Each rule has its own answer. The address rule is the one in the opening. The others are taught below as themselves.
The certificate notice
The 30 days run from the date of the change in permanent mailing address. The two methods in the section are the letter to the Airman Certification Branch and the FAA website. A post office box is not enough by itself. The holder also provides the current residential address.
A name change is paragraph (a) of the same section, and it is a different process. An application to change the name on the certificate must include the remote pilot certificate and a copy of the marriage license, court order, or other document verifying the name change. Those documents are returned after inspection. Do not treat a name change as a 30-day website note, and do not treat an address change as a request for a new certificate. Currency of the certificate, which is a 24-calendar-month issue under §107.65, is separate again and is covered on the recurrent training page. A temporary certificate has its own life, described on the temporary certificate page.
An expired registration is not a 30-day grace period
A remote pilot registered a mapping drone a little over three years ago and never renewed. A paid survey scheduled for this afternoon is not a legal Part 107 flight of that aircraft. Small unmanned aircraft registration is valid for 3 years and must be renewed before it expires. An expired registration does not satisfy §107.13. A current remote pilot certificate does not keep the aircraft registered. Registration does not last for the life of the airframe. There is no 30-day grace period after the registration expires.
The 30 days in §107.77 are only the certificate-address deadline. Using that number as a registration grace period is the trap. The aircraft registration page states the Part 107 figure already: registration is $5 and is valid for 3 years. This page does not add a different renewal charge. Renew before the three years end, and keep that clock off the address clock.
Who may register the aircraft when the owner is 12
Section 48.25 says a small unmanned aircraft must be registered by its owner, unless the owner is less than 13 years of age. If the owner is less than 13, the aircraft must be registered by a person who is at least 13 years of age. A 12-year-old owner is not the registrant. "Nobody can register it because the owner is under 16" confuses this rule with remote-pilot eligibility. The minimum age to hold a remote pilot certificate is 16. That age does not set the registration age, and it does not block registration of an aircraft owned by someone younger, as long as a person who is at least 13 is the registrant.
A Remote ID letter of authorization is a third permission
The last assigned item asks who would most likely be eligible to request a Remote ID deviation through a letter of authorization. The answer is an organization conducting aeronautical research, or a drone light show operating under a waiver. The explanation for that item says the request goes to RIDAuthorizations@faa.gov. Cost is not a qualifying ground. Weight is not a qualifying ground. Airspace class is not a qualifying ground. A real estate photographer who finds broadcast modules too expensive does not qualify on that complaint. A recreational flyer whose drone weighs under 250 grams does not qualify on weight alone.
FAA Remote ID guidance describes the same kind of authorization for limited purposes such as aeronautical research or showing compliance with the regulations. The purpose is requested and granted. It is not self-declared because the flight would be cheaper without a broadcast module. It is also not the §107.77 address notice, and it is not aircraft registration.
Three clocks, three actions. Notify the FAA of a permanent mailing-address change within 30 days if you will keep flying as remote pilot. Renew aircraft registration before the 3-year term ends. Ask for a Remote ID deviation only when the operation is the kind of case the FAA actually authorizes.
