1. Purpose of This Notice. This notice serves to remind General Aviation Safety Assurance office managers and aviation safety
inspectors (ASI) of an impending deadline affecting Letter of Authorization (LOA) B039, Operations in North Atlantic High Level Airspace (NAT HLA), for Title 14 of
the Code of Federal Regulations (14 CFR) part
notice also requests action to notify operators holding expiring LOAs and of the existence of new contingency procedures for operations in North Atlantic (NAT) airspace.
2. Audience. The primary audience for this notice is General Aviation Safety Assurance office and International Field Office (IFO)
managers and ASIs assigned oversight of part
The secondary audience includes the Safety Standards and Foundational Business offices.
Note: While the requirements highlighted in this notice also apply to 14 CFR parts
of those operators have obtained an amended operations specification (OpSpec)/management specification (MSpec) B039 based on the most recent template revision. However,
as is mentioned in subparagraph 4a, because a significant number (more than 1,000) of part
have not yet obtained an amended LOA B039 based on the current template, the target audience for this notice is part

a. FAA Notice N
B039, Operations in North Atlantic High Level Airspace (NAT HLA), published on June 10, 2016, announced a mandatory revision to all B039 templates (previously titled
“Operations in North Atlantic Minimum Navigation Performance Specifications (NAT/MNPS) Airspace”). Guidance in the notice is now incorporated into inspector
guidance for B039 in FAA Order 8900.1,
Volume 3, Chapter 18, Section 4, Part
B Operations SpecificationsEn Route Authorizations and Limitations. The notice announced not only a change to the LOA title to “Operations in North Atlantic
High Level Airspace (NAT HLA),” but also significant changes to the content of the LOA, among them that LOA B036, Oceanic and Remote Continental Navigation Using
Multiple Long-Range Navigation Systems (M-LRNS) or LOA B054, Oceanic and
Remote Continental Navigation Using a Single Long-Range Navigation System, is now a prerequisite for issuing LOA B039. The notice also announced a deadline of December 31, 2019, to complete the
transition to LOA B039 based on the latest template revision, 030. Effective January 1, 2020, operators holding the old NAT/MNPS LOA B039 may not fly in the NAT HLA.
The notice included, in paragraph 7, a recommendation that Flight Standards offices develop appropriate reissuance schedules in order to avoid excessive workload as the
deadline approaches. As of the date of this notice, a significant number of part
continue to hold previous template revisions of the NAT/MNPS LOA B039.
b. The Technical Programs Branch (AFS-260) in the Air Transportation Division (AFS-200) has created a custom query in the Web-based
Operations Safety System (WebOPSS) for all part
with LOA B039 issued. The query includes the effective date of LOA B039 and the revision and status of the template on which the LOA was issued. For those LOA B039
operators, the effective date and template status of their LOA B036 is also displayed, if issued. The Principal Operations Inspector’s (POI) name and email are
displayed, if available. The query is sorted by default by the former region, office, then by missing or old LOA B036, then by the LOA B039 template revision and
with the latest LOA B036 and B039 revisions will appear at the bottom of the list for each office. The report is available to all ASIs and FAA support personnel with
access to WebOPSS. In WebOPSS, navigate to “Tools”“Reports”“Custom.” On the “WebOPSS HQ Reports” page, select
B - En Route”“91
B039 and B036 Issuance.”
5. Action. General Aviation Safety Assurance office and IFO managers should identify part
with LOAs issued by their office who still hold the NAT/MNPS LOA B039 based on previous revisions of the template.
a. Between Now and January 1, 2020. ASIs should attempt to contact those operators and inform them of the impending deadline for
transition to the current LOA B039 template. ASIs should advise operators not to delay further in requesting an amended LOA B039 for NAT HLA. Order 8900.1,
Volume 3, Chapter 18, Section 4 identifies
the requirements for issuing the current LOA B039. The requirements for operations in NAT HLA differ somewhat from those for operations in the former NAT/MNPS. Now,
operators applying for LOA B039 have to provide ASIs with additional evidence of compliance with NAT HLA requirements, particularly with regard to the navigation
specification (Required Navigation Performance (RNP) 10 is now required) and flightcrew training. ASIs should not assume operators with the NAT/MNPS LOA B039 already
have the aircraft equipage, operating procedures, and training in place for the current NAT HLA LOA B039.
b. Beginning on January 2, 2020. ASIs should follow guidance in Order 8900.1,
Volume 3, Chapter 18, Section 2, Paragraph
3-711B, Mandatory Changes (as this is a mandatory template change), to archive any LOA B039 not issued using the most recent template revision (030).
6. Additional Action Regarding New NAT Contingency Procedures. The International Civil Aviation Organization (ICAO) and the FAA issued
new contingency procedures for use in NAT airspace, changing the lateral offset to 5 nautical miles (NM). Pilots use these contingency procedures when they must deviate
from their assigned route (e.g., because of emergency or weather) before they can obtain a revised clearance from air traffic control (ATC). The FAA issued Information
for Operators (InFO)
North Atlantic (NAT) Contingency Procedures Applicable in New York Oceanic Airspace, on the new procedures on March 21, 2019. The FAA also published a notice on the
procedures in the
Notice to Airmen Publication (NTAP)
(Part 2, International NOTAMs, Section 2, International Oceanic Airspace Notices) beginning with the February 28, 2019, edition. The ICAO NAT Office published
the new contingency procedures in
NAT OPS Bulletin 2018_005 Rev 01, Special
Procedures for In-Flight Contingencies in Oceanic Airspace, effective March 28, 2019. Although InFO
focused on airline operators, the new contingency procedures are in fact applicable to all operators flying throughout the NAT region (all altitudes), to include the
entire New York oceanic control area (OCA) (i.e., NY OCA East and West). These new procedures are critical to operations in the busy NAT HLA. We request that the General
Aviation Safety Assurance office and IFO managers inform part
of the new contingency procedures. Additionally, ASIs should not issue an amended LOA B039 without first confirming the part
has incorporated the new contingency procedures in the applicable operator handbooks, flight manuals, etc. The Flight Operations Group, Section D (AFS-410D) has
specialists situated throughout the country, with whom ASIs should coordinate prior to issuing/re-issuing LOA B039 (refer to Order 8900.1,
Volume 4, Chapter 12, Section 1, Issue
a Letter of Authorization). Until the Operations Approval Portal System (OAPS) accommodates issuance of LOA B039, use the appropriate Special Area of Operation (SAO)
Tracker to facilitate this coordination.
7. Summary. The following summarizes the main points of this notice:
• LOA B039 template revision 030 (or subsequent revision) will be the
only version valid after December 31, 2019.
• LOA B036
or LOA B054 is now a prerequisite to LOA B039 and RNP 10 navigation
specification is now required for LOA B039.
• NAT contingency procedures have been changed, effective March 28, 2019.
• Coordinate with specialists in AFS-410D (via the SAO Tracker) prior
to issuing/re-issuing LOA B039.
8. Disposition. We will not incorporate the information in this notice into Order 8900.1 before this notice expires. Direct questions
concerning the information in this notice to the Flight Technologies and Procedures Division (AFS-400) at 202-267-8790.
