1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2022-04-05 The Boeing Company: Amendment 39-21947; Docket No. FAA-2022-0095; Project Identifier AD-2022-00054-T. (a) Effective Date This airworthiness directive (AD) is effective February 14, 2022. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company airplanes identified in paragraphs (c)(1) and (2) of this AD, certificated in any category. (1) Model 757-200, -200PF, -200CB, and -300 series airplanes. (2) Model 767-200, -300, -300F, -400ER, and -2C series airplanes. (d) Subject Air Transport Association (ATA) of America Code 34, Navigation. (e) Unsafe Condition This AD was prompted by a determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band), and a determination that, during approach, landings, and go-arounds, as a result of this interference, certain airplane systems may not properly function, resulting in increased flightcrew workload while on approach with the flight director, autothrottle, or autopilot engaged. The FAA is issuing this AD to address 5G C-Band interference that could result in increased flightcrew workload and could lead to reduced ability of the flightcrew to maintain safe flight and landing of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Airplane Flight Manual (AFM) Revision (1) Within 2 days after the effective date of this AD: Revise the Limitations Section of the existing AFM to include the information specified in figure 1 to paragraph (g)(1) of this AD. This may be done by inserting a copy of figure 1 to paragraph (g)(1) of this AD into the Limitations Section of the existing AFM. BILLING CODE 4910-13-P ER14FE22.012 (2) Within 2 days after the effective date of this AD: Revise the Operating Procedures Section of the existing AFM to include the information specified in figure 2 to paragraph (g)(2) of this AD. This may be done by inserting a copy of figure 2 to paragraph (g)(2) of this AD into the Operating Procedures Section of the existing AFM. ER14FE22.013 BILLING CODE 4910-13-C Note 1 to paragraph (g)(2): Guidance for accomplishing the actions required by paragraph (g)(2) of this AD can be found in Boeing Multi Operator Message MOM-MOM-22-0022-01B(R2), dated February 1, 2022; Boeing Flight Crew Operations Manual Bulletin TBC-67 R1, "Radio Altimeter Anomalies due to 5G C-Band Wireless Broadband Interference in the United States," dated February 1, 2022; Boeing Flight Crew Operations Manual Bulletin TBCC-72 R1, "Radio Altimeter Anomalies due to 5G C-Band Wireless Broadband Interference in the United States," dated February 1, 2022; Boeing Flight Crew Operations Manual Bulletin TBC-86 R1, "Radio Altimeter Anomalies due to 5G C-Band Wireless Broadband Interference in the United States," dated February 1, 2022; and Boeing Flight Crew Operations Manual Bulletin TBC4-33 R1, "Radio Altimeter Anomalies due to 5G C-Band Wireless Broadband Interference in the United States," dated February 1, 2022.
