4. Background.

a. B030. Revised remote continental authorizations are the product of a navigation policy review spawned by the Don Young Alaska Aviation Safety Initiative (DYAASI). The new B030 authorization, now also available (but not required) for part 91 operators, relies on guidance on “proceeding safely” and dead reckoning published in April 2025 in Advisory Circular (AC) 91-70D, Oceanic and Remote Continental Airspace Operations.

b. B036. The new oceanic B036 authorization now incorporates a single long-range navigation system (LRNS) authorization, assuming a role the B054 authorization previously fulfilled. The new B036 authorization was the product of streamlining recommendations along with an effort to simplify how a part 91 Responsible Person is designated, as discussed in Notice N 8900.709, Revised Part 91 LOA A001 Template Affecting the “Responsible Person,” issued on August 14, 2024. Also, the 2019 General Aviation (GA) International Authorizations and Tabletop Exercises (GIATE) Working Group (WG) recommended development of the new “Risk Assessment Worksheet” now added to inspector guidance to determine whether to conduct a “tabletop” evaluation for a part 91 B036 application.

c. B039. The March 2025 removal of the “Blue Spruce” routes, with updates to the corresponding navigation capability requirements in the North Atlantic (NAT), rendered single LRNS authorizations in the current B039 templates out of date. Updated B039 templates authorize such operations in the newly created “Iceland-Greenland Corridor.” d. Related Notice. FS issued the following related notice concurrently with this notice: N 8900.757, Revised B030, B036, and B039 Authorizations, Decommissioned B054 Authorization for 14 CFR Parts 91K, 121, 121/135, 125, and 135.

12/30/25 N 8900.756 5. Template Revisions for Part 91. FS has revised part 91 LOA templates, including new titles. The following table presents these titles: Part 91 LOA Title Remarks B030 IFR Remote Continental The new part 91 LOA is not required to conduct Operations and/or IFR such operations but is available to document Alaska Special Minimum FAA recognition of an operator’s remote En Route Altitude (MEA) continental training and procedures.

Operations B036 Oceanic Required • Is a nonmandatory template revision.

Navigation Performance • Table 2 (listing the “Responsible Person”) (RNP) Operations has been removed, as this is now addressed in LOA A001, Issuance and Applicability.

(Note: Title is changed.)

• Required for operators to indicate oceanic RNP on an air traffic control (ATC) flight plan and to operate in airspace where oceanic RNP is required.

• Recommended (though not required) for part 91 oceanic flights. However, without a B036 authorization, operators must not indicate oceanic RNP on the ATC flight plan.

B039 Operations in North Atlantic • Is a nonmandatory template revision, except High Level Airspace for operators authorized NAT HLA (NAT HLA) operations using a single long-range navigation system (LRNS), in which case the new template is mandatory.

• Required for part 91 flights in NAT HLA.

B054 Oceanic RNP 10 Operations • Is decommissioned.

Using a Single Long-Range • A single LRNS option is now available in the Navigation System new LOA B036.

6. Revisions to Guidance Documents.

a. FAA Order 8900.1, Flight Standards Information Management System. 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 LOAs B030, B036, B039, and B054. FS has also added a new Risk Assessment Worksheet to B036 guidance (refer to Order 8900.1, Volume 3, Chapter 18, Section 4, Figure 3-321, Title 14 CFR Part 91 LOA B036 Risk Assessment Worksheet), which helps inspectors determine whether “tabletop” validation tests are required for a given part 91 B036 application.

b. AC 91-70, Oceanic and Remote Continental Airspace Operations. In addition, FS published a revised AC 91-70D in April 2025 to discuss regulatory aspects and provide training topics.

12/30/25 N 8900.756 7. Authorization Templates. Appendices to this notice show the new/revised templates. This notice contains the following: Appendix Authorizing Document Paragraph Applicable to Part A LOA B030 91 B LOA B036 91 C LOA B039 91 8. Action.

a. Issue New Authorizations. Inspectors should issue applicable new authorizations as follows: (1) LOA B030. This is new for part 91, available but not required for part 91 operators to conduct the associated operations.

(2) LOA B036. This is a nonmandatory template revision to the LOA B036 template.

(3) LOA B039. This is a nonmandatory template revision to the LOA B039 template, except for single LRNS authorizations associated with the B054 authorization, in which case the revision is mandatory. Existing single LRNS authorizations in LOA B039 continue to be valid for 12 months after the date of this notice, with the “special” routes now pertaining to the “Iceland-Greenland Corridor.” Single LRNS authorizations within existing LOA B039s expire 12 months after the date of this notice. New single LRNS authorizations must then use the updated LOA B039 template.

b. Archive LOA B054. The LOA B054 template is being decommissioned. All issued LOA B054s are to be archived upon issuing the revised LOA 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 LOA A004, Summary of Authorizations; reissue A004; and archive B054 at that time so that the operator does not have overlapping authorizations. Inspectors should archive any remaining issued B054s.

c. Reissue LOAs A001, Issuance and Applicability, and A004, Summary of Authorizations. The part 91 LOAs B030, B036, and B039 designate the person listed in Table 1 of LOA A001 (revision 02c or later, per N 8900.709) as the Responsible Person. When issuing LOAs B030, B036, and/or B039, the inspector should confirm the operator’s issued LOA A001 has the current Responsible Person information and, as applicable, reissue LOA A001 using the latest template revision. The operator’s A004 should also be reissued to deauthorize the B054 and reflect the new authorizing statement associated with the revised B036 template. See subparagraph 8b above for archiving steps for B054.

12/30/25 N 8900.756 d. 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 designations of 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.

(2) All oceanic flights with aircraft not providing Automatic Dependent Surveillance-Contract (ADS-C) reports.

7. Responsible Person. The Responsible Person for this authorization is listed in Table 1 of LOA A001 (revision 02c or later), Issuance and Applicability.

B-3

12/30/25 N 8900.756 Appendix C Appendix C. Sample LOA B039, Operations in North Atlantic High Level Airspace (NAT HLA): 14 CFR Part 91 1. The operator is authorized to conduct operations in North Atlantic High Level Airspace (NAT HLA) in accordance with the provisions of this Letter of Authorization (LOA) and the guidance contained in International Civil Aviation Organization (ICAO) Doc 7030, Regional Supplementary Procedures, for the NAT region.

2. Airspace Description. NAT HLA is that volume of airspace (as defined in ICAO Doc 7030) between flight level (FL) 285 and FL 420 within the oceanic control areas of Bodo Oceanic, Gander Oceanic, New York Oceanic East north of 27° N, Reykjavik, Santa Maria, and Shanwick, excluding the Shannon and Brest Ocean Transition Areas.

3. Required Flightcrew Training. Prior to operations in NAT HLA, flightcrew members must have completed the operator’s training on the requirements specific to planning and operating flights in the NAT HLA. This training is in addition to that provided by the operator on the general requirements for planning and operating flights in oceanic and remote airspace.

4. The operator must also hold LOA B036, Oceanic Required Navigation Performance (RNP) Operations, indicating authorization for RNP 2 (oceanic/remote), RNP 4, or RNP 10, except if operating in accordance with subparagraph 5 below.

5. In accordance with 14 CFR Part 91, § 91.511, flights in an airplane using only a single long-range navigation system (LRNS) over water more than 30 minutes flying time or 100 nautical miles (NM) from the nearest shore are limited to the geographic area defined in § 91.511(f), if that section is applicable. Operations within NAT HLA using a single LRNS must comply with § 91.511, if applicable. Such operators, as well as operators with more than one LRNS who do not hold LOA B036, are limited to the special “Iceland-Greenland Corridor” described in NAT Doc 007, North Atlantic Operations and Airspace Manual. Table 1 provides the operator status with respect to B036 LOA and the associated NAT HLA restriction.

Table 1 – B036 Restriction, Iceland-Greenland Corridor o Operator is using only a single LRNS and/or is n ot authorized oceanic RNP in LOA B036.

NAT HLA operations are therefore restricted to the Iceland - Greenland Corridor .

o Operator is authorized oceanic RNP in LOA B036 . NAT HLA operations are therefore authorized, including outside the Iceland - Greenland Corridor.

6. Responsible Person. The Responsible Person for this authorization is listed in Table 1 of LOA A001 (revision 02c or later), Issuance and Applicability.
