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: 2022-06-18 The Boeing Company: Amendment 39-21984; Docket No. FAA-2022-0280; Project Identifier AD-2021-00504-T. (a) Effective Date This airworthiness directive (AD) is effective April 18, 2022. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company Model 767-2C series airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 21, Air conditioning. (e) Unsafe Condition This AD was prompted by a report of multiple nuisance caution "RECIRC SMOKE" engine indication and crew alerting system (EICAS) messages that may occur when water accumulates in the alternative ventilation system (AVS) duct. The FAA is issuing this AD to address water accumulation in the AVS duct, which can block AVS system airflow into the airplane, creating a loss of conditioned inflow and result in cold or hot flight deck temperatures, and potentially affect the flightcrew's ability to maintain continued safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Replacement and Installation Within 36 months after the effective date of this AD: Replace the alternative ventilation duct having part number (P/N) 216T2101-704 with P/N 216T2101-707; and change the insulation blanket to install the drain hose, as applicable; in accordance with a method approved by the Manager, Seattle ACO Branch, FAA. (h) Parts Installation Prohibition As of the effective date of this AD, no person may install an alternative ventilation duct, P/N 216T2101-704, on any airplane. (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, Seattle ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: [email protected]. (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by The Boeing Company Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO Branch, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD.
