SUPPLEMENTARY INFORMATION: SUMMARY: PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 6561 Background The Convention on Cultural Property Implementation Act, Public Law 97– 446, 19 U.S.C. 2601 et seq. (hereinafter, ‘‘the Cultural Property Implementation Act’’), implements the 1970 United Nations Educational, Scientific and Cultural Organization (UNESCO) Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property (823 U.N.T.S. 231 (1972)) (hereinafter, ‘‘the Convention’’). Pursuant to the Cultural Property Implementation Act, the Government of the United States entered into a bilateral agreement with the Government of the Kingdom of Morocco (Morocco) to impose import restrictions on certain archaeological and ethnological material from Morocco on January 14, 2021. This rule announces the imposition of import restrictions on certain archaeological and ethnological material from Morocco. Determinations Under 19 U.S.C. 2602(a)(1), the United States must make certain determinations before entering into an agreement to impose import restrictions under 19 U.S.C. 2602(a)(2). On April 30, 2020, the Assistant Secretary for Educational and Cultural Affairs, United States Department of State, after consultation with and recommendation by the Cultural Property Advisory Committee, made the determinations required under the statute with respect to certain archaeological and ethnological material from Morocco that is described in the Designated List set forth below in this document. These determinations include the following: (1) That Morocco’s cultural heritage is in jeopardy from pillage of certain types of archaeological material representing Morocco’s cultural heritage ranging in date from approximately 1 million B.C. to A.D. 1750 and certain types of ethnological material representing Morocco’s cultural heritage from the Saadian and Alaouite dynasties ranging in date from approximately A.D. 1549 to 1912 (19 U.S.C. 2602(a)(1)(A)); (2) that the Moroccan government has taken measures consistent with the Convention to protect its cultural patrimony (19 U.S.C. 2602(a)(1)(B)); (3) that import restrictions imposed by the United States would be of substantial benefit in deterring a serious situation of pillage and remedies less drastic are not available (19 U.S.C. 2602(a)(1)(C)); and (4) that the application of import restrictions as set forth in this final rule is consistent with the general interests of the international community in the E:\FR\FM\22JAR1.SGM 22JAR1

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to M7 Aerospace LLC Models 
SA26-AT and SA26-T airplanes. The NPRM published in the Federal 
Register on October 14, 2020 (85 FR 64993). The NPRM was prompted by 
reports of the airplane power lever linkage detaching from the TPE331 
engine PPC shaft. In the NPRM, the FAA proposed to require repetitively 
inspecting the PPC for proper torque and making any necessary 
corrections until the replacement of the PPC assembly and the 
installation of a secondary retention feature (safety wire) are done. 
The FAA is issuing this AD to prevent uncommanded change to the engine 
power settings with consequent loss of control.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adopting this AD as proposed. Accordingly, the FAA is issuing 
this AD to address the unsafe condition on these products. This AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Honeywell International Inc. Service Bulletin 
TPE331-72-2190, dated December 21, 2011, which contains procedures for 
replacing or reworking the propeller pitch control assembly, 
incorporating a threaded hole in the splined end of the shouldered 
shaft, and reassembling the propeller pitch control assembly. Honeywell 
International Inc. Service Bulletin TPE331-72-2190, dated December 21, 
2011, was previously approved for IBR on May 5, 2017 (82 FR 15982, 
March 31, 2017). This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in ADDRESSES.

Other Related Service Information

    The FAA also reviewed paragraph j. of M7 Aerospace SA26 Series 
Maintenance Manual Temporary Revision 4-02, dated July 22, 2020, which 
contains information related to the installation of the secondary 
retention feature (safety wire) on the airplane PPC lever and the PPC 
assembly.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-01-02 M7 Aerospace LLC: Amendment 39-21378; Docket No. FAA-
2020-0910; Project Identifier 2018-CE-044-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective February 26, 
2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to M7 Aerospace LLC Model SA26-AT and SA26-T 
airplanes, all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 61, Propellers/
propulsors.

(e) Unsafe Condition

    This AD was prompted by reports of the airplane power lever 
linkage detaching from the TPE331 engine propeller pitch control 
(PPC) shaft. The FAA is issuing this AD to address detachment of the 
power lever linkage to the TPE331 engine PPC shaft, which could 
result in uncommanded change to the engine power settings with 
consequent loss of control.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) PPC Lever Inspection

    (1) Within 100 hours time-in-service (TIS) after the effective 
date of this AD and thereafter at intervals not to exceed 100 hours 
TIS, inspect the security of the PPC lever by pulling the PPC lever 
upward by hand to ensure it does not detach from the PPC input 
shaft. If the PPC lever detaches during any inspection, before 
further flight, comply with paragraphs (h) and (i) of this AD.
    (2) The replacement/re-identification required by paragraph (h) 
of this AD and the installation of the secondary retention feature 
(safety wire) required by paragraph (i) of this AD terminate the 
repetitive inspections of the PPC lever attachment required by 
paragraph (g)(1) of this AD.

(h) Replace and Inspect the PPC Assembly

    Within 600 hours TIS after the effective date of this AD or 
within 12 months after the effective date of this AD, whichever 
occurs first, unless required before further flight by paragraph 
(g)(1) of this AD, do the actions in either paragraph (h)(1) or (2) 
of this AD in accordance with the Accomplishment Instructions in 
Honeywell International Inc. Service Bulletin TPE331-72-2190, dated 
December 21, 2011, except you are not required to report information 
to the manufacturer.
    (1) Replace the PPC assembly with the applicable new design PPC 
assembly.
    (2) Inspect the splined end of the shouldered shaft for the 
presence and condition of a threaded hole and, before further 
flight, repair or replace the cam assembly or rework the PPC 
assembly, as necessary, and re-identify the shouldered shaft.

[[Page 6561]]

(i) Secondary Retention Feature (Safety Wire)

    Before further flight after completing the actions required by 
paragraph (h) of this AD, install the secondary retention feature 
(safety wire) on the airplane PPC lever and the PPC assembly.

    Note 1 to paragraph (i): Paragraph j. of M7 Aerospace SA26 
Series Maintenance Manual Temporary Revision 4-02, dated July 22, 
2020, contains information related to installation of the secondary 
retention feature (safety wire).

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Safety Management Section, Small Airplane 
Standards 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 local Flight Standards District 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 (k)(1) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
