Federal Register / Vol. 86, No. 97 / Friday, May 21, 2021 / Proposed Rules b Affected ADs This AD replaces AD 20202105, Amendment 3921278 85 FR 64963, October 14, 2020 AD 20202105.
c Applicability This AD applies to all Airbus SAS
airplanes, certificated in any category, and identified in paragraphs c1 through 9 of this AD.
1 Model A330223F and 243F airplanes.
2 Model A330201, 202, 203, 223, and 243 airplanes.
3 Model A330301, 302, 303, 321, 322, 323, 341, 342, and 343 airplanes.

7 Model A340311, 312, and 313
airplanes.
8 Model A340541 airplanes.
9 Model A340642 airplanes.
d Subject Air Transport Association ATA of America Code 28, Fuel.
e Reason This AD was prompted by reports of a fuel pump showing cavitation erosion that exposed the fuel pump power supply wires, and by a determination that certain compliance times need to be revised and that additional airplanes are subject to the unsafe condition. The FAA is issuing this AD to address fuel pump erosion caused by cavitation. If this condition is not addressed, a pump running dry could result in a fuel tank explosion and consequent loss of the airplane.
f Compliance Comply with this AD within the compliance times specified, unless already done.

6 Where paragraphs 8, 9, and 10 of EASA AD 20200283 specify to inform all flight crews, and, thereafter, operate the aeroplane accordingly, this AD does not require those actions as those actions are already required by existing FAA operating regulations.
i No Reporting Requirement Although the service information referenced in EASA AD 20200283 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
j Other FAA AD Provisions The following provisions also apply to this AD:
1 Alternative Methods of Compliance AMOCs: The Manager, Large Aircraft Section, International Validation 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 Large Aircraft Section, International Validation Branch, send it to the attention of the person identified in paragraph k2 of this AD.
Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
2 Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, Large Aircraft Section, International Validation Branch, FAA; or EASA; or Airbus SASs EASA Design Organization Approval DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
3 Required for Compliance RC: For any service information referenced in EASA AD
20200283 that contains RC procedures and tests: Except as required by paragraph j2
of this AD, RC procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operators maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.

Restriction of Emissions From Lithographic and Letterpress Printing Operations Environmental Protection Agency EPA.
ACTION: Proposed rule.
AGENCY:

The Environmental Protection Agency EPA is proposing to approve revisions to the Missouri State Implementation Plan SIP received on November 10, 2020. The submission revises a Missouri regulation that restricts volatile organic compound emissions from lithographic and letterpress printing operations in the St.
Louis Metropolitan Area. Specifically, the state has revised this rule in order to clarify rule applicability, update incorporation by reference information, update test method reference, clarify definitions, and remove the unnecessary use of restrictive words to improve clarity. Approval of these revisions will ensure consistency between state and federally-approved rules.
DATES: Comments must be received on or before June 21, 2021.
