Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2021-15-04 The Boeing Company: Amendment 39-21651; Docket No. FAA- 2021-0566; Project Identifier MCAI-2021-00733-T. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) becomes effective July 14, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to The Boeing Company Model 767-300 series airplanes, certificated in any category, that have been modified to a Bedek Division Special Freighter (BDSF), in accordance with FAA Supplemental Type Certificate (STC) ST02040SE (the freighter configuration is designated as 767-300BDSF), and which are listed in paragraph 1.A., ''Effectivity,'' of IAI-Aviation Group Alert Service Bulletin 368-24-098, Revision 1, dated June 2021. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 24, Electrical Power. \n\n(e) Reason \n\n\n\tThis AD was prompted by a report that the electrical diagram for the C9066 circuit breaker connection (wiring) for the ''Main Deck Oxygen Alert Control'' is erroneous and might have resulted in incorrect installation. The FAA is issuing this AD to address potential incorrect installation of the ''Main Deck Oxygen Alert Control'' circuit breaker, which could result in overheating and burning of the wiring, and consequently, could result in smoke triggering an alarm and causing the crew workload to increase; or could result in a short circuit to adjacent wires causing malfunctions in other systems. Furthermore, since this is a potentially unprotected circuit, if any failure occurs along the length of this circuit it could result in a fire and cause collateral damage to adjacent circuits and affect critical systems necessary for continued safe flight and landing. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Inspection, Wiring Connection Change, and Test \n\n\n\tWithin 10 days after the effective date of this AD, perform a detailed inspection of the wiring connection common to the C9066 circuit breaker to make sure 20 AWG wire is connected to terminal 1 and the BUS is connected to terminal 2, in accordance with steps 1. through 3. of the Accomplishment Instructions of IAI-Aviation Group Alert Service Bulletin 368-24-098, Revision 1, dated June 2021. If 20 AWG wire is not connected to terminal 1 or the BUS is not connected to terminal 2, before further flight, make changes to the wiring connection and test the main deck oxygen alert system, in accordance with steps 4. through 13. of the Accomplishment Instructions of IAI-Aviation Group Alert Service Bulletin 368-24- 098, Revision 1, dated June 2021. \n\n(h) No Report \n\n\n\tAlthough IAI-Aviation Group Alert Service Bulletin 368-24-098, Revision 1, dated June 2021, specifies to report inspection findings, this AD does not require any report. \n\n(i) Alternative Methods of Compliance (AMOCs) \n\n\n\t(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 \n\n((Page 37022)) \n\ninformation directly to the manager of the certification office, send it to the attention of the person identified in Related Information. Information may be emailed to: [email protected]. \n\t(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. \n\n(j) Related Information \n\n\n\t(1) Refer to Mandatory Continuing Airworthiness Information (MCAI) Civil Aviation Authority of Israel (CAAI) Israeli AD ISR-I- 24-2021-6-6R1, dated June 27, 2021, for related information.
