4. Background.
a. Advisory Circular (AC) 91-70D, Oceanic and Remote Continental Airspace Operations. On April 3, 2025, FS published AC 91-70D, which includes expanded guidance on “proceeding safely” and dead reckoning.
b. B030 Authorization. Revised remote continental authorizations are the product of a navigation policy review generated by the Don Young Alaska Aviation Safety Initiative (DYAASI). The new B030 authorization relies on expanded guidance on “proceeding safely” and dead reckoning published in AC 91-70D.
c. B036 Authorization. The new oceanic B036 authorization, which now incorporates single long-range navigation system (LRNS) authorization (with decommissioning of the B054 authorization), was the product of streamlining recommendations, and also of the DYAASI navigation policy review mentioned above.
d. B039 Authorization. The March 2025 removal of the “Blue Spruce” routes in the North Atlantic (NAT), together with the decommissioning of the B054 authorization announced in this notice, rendered single LRNS authorizations with B054 and Required Navigation Performance (RNP) 10 prerequisites in the current B039 templates out of date. Updated B039 templates authorize such operations in the newly created “Iceland-Greenland Corridor.” e. B050 Authorization. Given the removal of the “Blue Spruce” routes mentioned in subparagraph d above, FS has deactivated all B050 authorized areas that included those routes.
FS has activated replacement areas that instead include the “Iceland-Greenland Corridor.” This action is not considered a template revision, so the B050 revision numbers have not changed.
f. Related Notices. The following notices were issued concurrently with this notice and include relevant content: (1) N 8900.756, Revised 14 CFR Part 91 Letters of Authorization (LOA) B030, B036, and B039, Decommissioned LOA B054. This notice announced revisions to 14 CFR part 91 B030, B036, and B039 LOAs, and the decommissioning of the part 91 B054 LOA. The part 91 B030, B036, and B039 LOAs have slightly different titles and/or purposes from those announced here.
5. Template Revisions for Parts 91K, 121, 121/135, 125 (Including Part 125 LODA Holders), and 135. FS has revised OpSpec/MSpec/part 125 LOA templates, including new titles, as shown in the following table:
12/30/25 N 8900.757 (2) N 8900.758, New B033 Authorization, Revision to A002 Authorization, and Decommissioning of B031, B032, B034, and B035 Authorizations. This notice announced revisions to domestic en route authorizations. The notice published a new “One-Hour Reliable Fix (1HRF) Operations” term and definition in the A002, Definitions and Abbreviations, authorization. The B033 authorization is limited to 1HRF Operations. The notice affects B050 reference paragraphs.
(3) N 8900.759, Adopting the “Gulf of America” Name in B050. This notice announced revisions to B050 areas with the “Gulf of Mexico” name in them.
5. Template Revisions for Parts 91K, 121, 121/135, 125 (Including Part 125 LODA Holders), and 135. FS has revised OpSpec/MSpec/part 125 LOA templates, including new titles, as shown in the following table: OpSpec/ MSpec/ Title Remarks Part 125 LOA B030 IFR Low Remote Continental • Previously, used only for Alaska to Operations and/or IFR Alaska authorize instrument flight rules (IFR) Special Minimum En Route navigation using Area Navigation (RNAV) Altitude (MEA) Operations systems and special MEA routes.
• Now also authorizes low (below flight (Note: Title is changed) level (FL) 180) remote continental operations.
• Part 125 LOA is new.
B036 Oceanic and High Remote • Authorizes oceanic RNP Operations.
Continental Operations • Authorizes High (at or above FL 180) Remote Continental Operations.
(Note: Title is changed) • Incorporates an optional single LRNS authorization previously provided via B054 authorization, with minor changes to the “certain geographic area” defined by coordinates, now aligned with 14 CFR § 91.511(f).
• In addition, the single LRNS authorization replaces the defunct “Blue Spruce Routes” with “Iceland-Greenland Corridor.” B039 Operations in North Atlantic High • Authorizes NAT HLA operations, Level Airspace (NAT HLA) including using a single LRNS.
• Aligns with new airspace name and requirements, replaces the defunct “Blue Spruce Routes” with “Iceland-Greenland Corridor.”
6. Revisions to FAA Order 8900.1. FS has revised inspector guidance in Order 8900.1, Volume 3, Chapter 18, Section 4, Part B Operations Specifications—En Route Authorization and Limitations, affecting the B030, B036, B039, B041, B050, and B054 authori...
8. Action. Inspector actions are as follows:
12/30/25 N 8900.757 8. Action. Inspector actions are as follows: a. Review Related Notices. Inspectors should review the related notices listed in subparagraph 4f above to determine whether their operators are affected. This review may be helpful in planning reissuance activities.
Note: The notices listed in subparagraph 4f were released concurrently to allow inspectors to update the applicable B050 reference paragraphs and authorized areas, and perform one B050 reissuance instead of three. However, due to the large number of revisions, the Safety Assurance System (SAS) Operations Safety System (OPSS) will not have all new templates available until January 16, 2026.
Inspectors are advised to wait until then to begin B050 reissuance actions.
b. Issue New Authorizations. This is a mandatory revision to the B030, B036, and B039 templates (exception: B030 is new for part 125 LODA holders). The B054 templates are being decommissioned. Inspectors should complete reissuances and archiving within 12 months of the effective date of this notice, as applicable. See subparagraph f below for decommissioning steps for B054.
c. Reissue A002, Definitions and Abbreviations, and A004, Summary of Special Authorizations and Limitations (as Required). When issuing the revised B030 or B036, inspectors must ensure that the version of A002 that includes the “1HRF” term is issued. B054 must be archived when issuing the revised B036. The operator’s A004 should also be reissued to deauthorize the B054 and reflect the new authorizing statements associated with the revised B030, B036, and B039 templates.
d. Advise Operators with B039 for Single LRNS Authorizations. Inspectors should advise operators that existing single LRNS authorizations in B039 continue to be valid up to 12 months after the date of this notice, with the “special” routes now pertaining to the “Iceland-Greenland Corridor.” New B039 templates align with the new airspace names and requirements published in International Civil Aviation Organization (ICAO) NAT Doc 007, North Atlantic Operations and Airspace Manual.
e. Update and Reissue B050. FS has updated the B050 authorized areas and reference paragraphs in inspector guidance and in the B050 dropdown menus in SAS OPSS. Inspectors should reissue B050 to remove any B054 reference paragraphs that are no longer needed, and/or add B030 or B036 reference paragraphs, as needed, and to replace any inactive areas (e.g., ones with “Blue Spruce Routes” in the name) with active areas.
f. Archive B054. The B054 templates are being decommissioned, All issued B054 authorizations are to be archived upon issuing the revised B036, or within 12 months of the date of this notice, whichever occurs first. The current B054 templates will be available until 6 months after the effective date of this notice to allow short-term revisions in advance of using the revised B036 template. When issuing the revised B036, inspectors should deauthorize B054 in the operator’s A004, reissue A004, and archive B054 at that time so that the operator does not have overlapping authorizations. Inspectors should archive any remaining issued B054s.
9. Disposition. We are issuing this notice concurrently with corresponding revisions to Order 8900.1. Relevant inspector guidance can thus now be found in Order 8900.1, Volume 3, Chapter 18, Section 4. Direct questions and comments concerning the info...
12/30/25 N 8900.757 g. Advise Operators to Update Manuals. PIs should also advise affected operators to update international operations guidance, procedures, and/or manuals to avoid use of obsolete names/terms and/or designations of OpSpecs/MSpecs/LOAs.
9. Disposition. We are issuing this notice concurrently with corresponding revisions to Order 8900.1. Relevant inspector guidance can thus now be found in Order 8900.1, Volume 3, Chapter 18, Section 4. Direct questions and comments concerning the information in this notice to the Flight Technologies and Procedures Division (AFS-400) at 9-AWA-AVS-AFS-400- Flight-Technologies-Procedures@faa.gov.
