Compliance Procedure
Verify the inclusion of the Radio Altimeter Flight Restrictions page in the R66 Pilot’s Operating Handbook and make appropriate maintenance record entries.
Background
The FAA has issued directives restricting operations of aircraft with radar altimeters not protected from 5G interference, necessitating the addition of a specific page to the flight manual.
Radio Altimeter Flight Restrictions
Certain operations requiring radio altimeter data are prohibited in U.S. airspace due to 5G interference, including specific approaches and autopilot modes.
Time of Compliance
Affected helicopters must comply within the next 100 flight hours or by March 31, 2025.
Approximate Cost
No parts are required, and the labor cost is estimated at 0.2 hours.
FAA Approval
The design engineering aspects of this bulletin have been shown to comply with applicable federal aviation regulations and are FAA approved.
Safety notes
- Prohibited operations include approaches requiring radio altimeter minimums.
- Hover autopilot modes requiring radio altimeter data are not allowed.
- Search and Rescue autopilot modes requiring radio altimeter data are prohibited.
- Takeoffs and landings requiring radio altimeter data are not permitted.

Page 1 of 2 R66 SERVICE BULLETIN SB-43 DATE: 27 January 2025 TO: R66 Owners, Operators, and Maintenance Personnel SUBJECT: Statement to Accompany AD 2023-11-07 ROTORCRAFT AFFECTED: R66 Helicopters equipped with a radar altimeter operating in the US and other countries implementing AD 2023-11-07 or equivalent. TIME OF COMPLIANCE: Within next 100 flight hours or by 31 March 2025. BACKGROUND: The FAA and other aviation authorities have issued airworthiness directives placing restrictions on the operation of aircraft with radar altimeters not protected from 5G C-Band wireless broadband transmission interference. These airworthiness directives require the addition of a page to the limitations section of the flight manual of affected aircraft. All R66 helicopters equipped with radar altimeters are affected and require this page. This service bulletin requires verification that the page has been added to the R66 Pilot’s Operating Handbook on all affected R66’s. See Statement to Accompany AD 2023-11-07 for additional information. COMPLIANCE PROCEDURE: 1. If helicopter is equipped with radar altimeter and operating in the US or other countries implementing an airworthiness directive equivalent to AD 2023-11-07, verify the inclusion of the Radio Altimeter Flight Restrictions page (shown on page 2 of this bulletin) before the table of contents page of the Limitations Section of the R66 Pilot’s Operating Handbook. If not already included, print and insert page provided on page 2 of this bulletin. 2. Make appropriate maintenance record entries. APPROXIMATE COST: Parts: None required (Radio Altimeter Flight Restrictions page included as part of Bulletin). Labor: 0.2 labor-hour. THE DESIGN ENGINEERING ASPECTS OF THIS BULLETIN HAVE BEEN SHOWN TO COMPLY WITH APPLICABLE FEDERAL AVIATION REGULATIONS AND ARE FAA APPROVED. Intentionally Blank R66 SB-43 Page 2 of 2 (Required by AD 2023-11-07) Radio Altimeter Flight Restrictions To be inserted before the table of contents page of the Limitations Section for all Robinson helicopters with radio (radar) altimeters. Due to the presence of 5G C-Band wireless broadband interference, when operating in the contiguous U.S. airspace, the following operations requiring radio altimeter are prohibited: • Performing approaches that require radio altimeter minimums for rotorcraft offshore operations. Barometric minimums must be used for these operations instead. • Engaging hover autopilot modes that require radio altimeter data. • Engaging Search and Rescue (SAR) autopilot modes that require radio altimeter data. • Performing takeoffs and landings in accordance with any procedure (Category A, Category B, or by Performance Class in the Rotorcraft Flight Manual or Operations Specification) that requires the use of radio altimeter data.
