Discussion 
The European Aviation Safety Agency 
(EASA), which is the Technical Agent 
for the Member States of the European Community, has issued AD No. 2017– 0208, dated October 13, 2017 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: 
Power loss and engine RPM drop have 
been reported on Rotax 912/914 engines in 
service. It has been determined that, due to 
a quality control deficiency in the manufacturing process of certain valve push- rod assemblies, manufactured between 08 June 2016 and 02 October 2017 inclusive, partial wear on the rocker arm ball socket may occur, which may lead to malfunction of the valve train. 
This condition, if not detected and 
corrected, may lead to rough engine operation and loss of power, possibly resulting in a forced landing, with consequent damage to the aeroplane and injury to occupants. 
To address this potential unsafe condition, 
BRP-Rotax issued Service Bulletin (SB) SB– 912 i-008/SB–912–070/SB–914–052 (single document), providing applicable instructions. 
For the reason described above, this 
[EASA] AD requires a one-time inspection and, depending on findings, replacement of affected parts. This [EASA] AD also prohibits installation of affected parts on an engine. 
You may examine the MCAI on the 
Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA–2017–1078.

FAA’s Determination and Requirements 
of This Proposed AD 
This product has been approved by 
the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. 
Costs of Compliance 
We estimate that this proposed AD 
will affect 63 products of U.S. registry. 
We also estimate that it would take about 1 work-hour per product to comply with the basic inspection requirement of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $70 per product. 
Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $9,765, or $155 per product. 
In addition, we estimate that any 
necessary follow-on actions would take about 2 work-hours to replace all 8 valve push-rod assemblies and 
associated parts on all 4 cylinders and require parts costing $3,093, for a cost of $3,263 per product. We have no way of determining the number of products that may need these actions. 
Authority for This Rulemaking 
Title 49 of the United States Code 
specifies the FAA’s authority to issue 
rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority. 
We are issuing this rulemaking under 
the authority described in ‘‘Subtitle VII, Part A, Subpart III, section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. 
This AD is issued in accordance with 
authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, and domestic business jet transport airplanes to the Director of the Policy and Innovation Division. 
Regulatory Findings 
We determined that this proposed AD 
would not have federalism implications 
under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. 
For the reasons discussed above, I 
certify this proposed regulation: 
(1) Is not a ‘‘significant regulatory 
action’’ under Executive Order 12866, 
(2) Is not a ‘‘significant rule’’ under 
the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), 
(3) Will not affect intrastate aviation 
in Alaska, and 
(4) Will not have a significant 
economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

(e) Reason 
This AD was prompted by mandatory 
continuing airworthiness information (MCAI) 
originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as defective 
valve push-rod assemblies manufactured from June 8, 2016, through October 2, 2017. We are issuing this AD to prevent rough engine operation, which could cause loss of power and result in loss of control. 
(f) Actions and Compliance 
Unless already done, do the following 
actions: 
(1) For aircraft with engines that have 160 
hours time-in-service (TIS) or less since first 
installed: Before exceeding 170 hours TIS on 
the engine since first installed or within the next 3 months after the effective date of this AD, whichever occurs first, visually inspect the valve push-rod ball sockets of each valve push-rod using the Accomplishment Instructions in Rotax Aircraft Engines BRP Service Bulletin SB–912 i–008 R1/SB–912– 070 R1/SB–914–052 R1 (co-published as one document), Revision 1, dated October 12, 2017 (Rotax SB SB–912 i–008 R1/SB–912– 070 R1/SB–914–052 R1). 
(2) For airplanes with engines that have 
160 hours TIS or more since first installed: Within the next 10 hours TIS after the effective date of this AD or within the next 3 months after the effective date of this AD, whichever occurs first, visually inspect the valve push-rod ball sockets of each valve push-rod using the Accomplishment Instructions in Rotax SB SB–912 i-008 R1/ SB–912–070 R1/SB–914–052 R1. 
(3) For all affected airplanes: If a valve 
push-rod with a black surface is found during the inspection required in paragraph (f)(1) or (f)(2) of this AD, before further flight, replace the valve push-rod and its affected parts with airworthy parts using the Accomplishment Instructions in Rotax SB SB–912 i-008 R1/ SB–912–070 R1/SB–914–052 R1. 
(4) For all affected airplanes: As of the 
effective date of this AD, do not install a valve push-rod that was manufactured from June 8, 2016, through October 2, 2017.

Vessel and Aircraft Discharges From 
United States Coast Guard Activities in Greater Farallones and Cordell Bank National Marine Sanctuaries 
AGENCY : Office of National Marine 
Sanctuaries (ONMS), National Ocean Service (NOS), National Oceanic and Atmospheric Administration (NOAA), Department of Commerce (DOC). 
ACTION : Proposed rule. 
SUMMARY : With this proposed rule, the 
National Oceanic and Atmospheric Administration (NOAA) considers allowing the United States Coast Guard (USCG or Coast Guard) to carry out certain otherwise prohibited activities within waters of Greater Farallones National Marine Sanctuary (GFNMS) and Cordell Bank National Marine Sanctuary (CBNMS) approximately 3 nautical miles (nm) from the shore, in the areas of the sanctuaries that were expanded in 2015. The discharges under consideration are: Untreated vessel sewage, vessel graywater as defined by the Federal Water Pollution Control Act, as amended (FWPCA), that does not meet the definition of ‘‘clean’’ as defined by the GFNMS and CBNMS regulations, and ammunition and pyrotechnic (warning projectile, flare, smoke float and marine marker) materials used in USCG training exercises for use of force (live fire or gunnery) and training exercises for search and rescue (SAR) of vessels or persons in distress. No change is proposed to the regulatory prohibitions or exceptions applicable to the pre- expansion boundaries of the two sanctuaries. A draft environmental assessment (DEA) under the National Environmental Policy Act (NEPA) has been prepared for this proposed action. NOAA is soliciting public comment on the proposed rule and DEA. 
DATES : Comments will be considered if 
received by January 16, 2018. Public hearings will be held on December 5 and 13, 2017, from 6 p.m. to 8 p.m.
