Energy Conservation Program: Energy 
Conservation Standards for Commercial Water Heating Equipment; Reopening of Comment Period 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Reopening of public comment 
period. 
SUMMARY : On May 31, 2016, the U.S. 
Department of Energy (DOE) published in the Federal Register a notice of proposed rulemaking (NOPR) that proposed amended energy conservation standards for commercial water heaters. DOE published this NOPR so stakeholders can review and provide input on these proposed revisions. The comment period for the NOPR pertaining to the subject commercial water heating equipment was scheduled to end August 1, 2016. After receiving a number of requests for additional time to comment, DOE has decided to reopen the public comment period until August 30, 2016 for the purposes of submitting comments on the NOPR or any other aspect of the energy conservation standards rulemaking for commercial water heating equipment. 
DATES : The comment period for the 
proposed rule published on May 31, 2016 (81 FR 34440) is reopened. DOE will accept comments, data, and information regarding the notice of proposed rulemaking received no later than August 30, 2016. 
ADDRESSES : Instructions: Any comments 
submitted must identify the NOPR on Energy Conservation Standards for Commercial Water Heating Equipment, and provide docket number EERE– 2014–BT–STD–0042 and/or regulatory information number (RIN) 1904–AD34. Comments may be submitted using any of the following methods:

SUPPLEMENTARY INFORMATION : On May 
31, 2016, DOE published in the Federal Register a notice of proposed 
rulemaking (NOPR) that proposed amended energy conservation standards for commercial water heaters. 81 FR 34440. The NOPR provided opportunity for submitting written comments, data, and information regarding the proposed amendments for the subject equipment by August 1, 2016. However, DOE received a request from the Air- Conditioning, Heating, and Refrigeration Institute (AHRI), dated July 22, 2016, to provide an additional 90 days in which to submit comments pertaining to the 
rulemaking for commercial water heaters. AHRI’s request can be found at: http://www.regulations.gov/document?D=EERE-2014-BT-STD-0042- 0023. AHRI and its members stated that 
they need more time to sufficiently review and digest the information in order to provide substantive comments. A reopening of the comment period would allow additional time for AHRI and its members and other interested parties to examine the data, information, and analysis presented in the Commercial Water Heaters Technical Support Document, to gather any additional data and information to address the proposed standards, and to submit comments to DOE. DOE also received requests from Raypak on July 25, 2016 and Spire on July 28, 2016 asking for additional time to carefully review the information provided by DOE and to provide substantive comments. Raypak’s request can be found at: http://www.regulations.gov/document?D=EERE-2014-BT-STD-0042- 0025. Spire’s request can be found at:

0026. After carefully considering the 
requests for additional time, DOE has 
determined that a reopening of the public comment period is appropriate, based upon the foregoing reasons. DOE believes that reopening the comment period until August 30, 2016 will provide the public with sufficient time to submit comments responding to DOE’s proposed energy conservation standards. Accordingly, DOE is reopening the comment period to midnight of August 30, 2016 and will deem any comments received by that date to be timely submitted. DOE further notes that any submissions of comments or other information submitted between the original comment end date and the reopening of the comment period will be deemed timely filed.

Airworthiness Directives; Airbus 
Airplanes 
AGENCY : Federal Aviation 
Administration (FAA), DOT. 
ACTION : Notice of proposed rulemaking 
(NPRM). 
SUMMARY : We propose to supersede 
Airworthiness Directive (AD) 2003–18– 06, for certain Airbus Model A319–131 and –132 airplanes; Model A320–231, –232, and –233 airplanes; and Model A321–131 and –231 airplanes. AD 2003–18–06 currently requires installing new anti-swivel plates and weights on the engine fan cowl door (FCD) latches and a new cowl door hold-open device. Since we issued AD 2003–18–06, we have received reports of additional engine FCD in-flight losses, and a new FCD front latch and keeper assembly has been developed to address this unsafe condition. This proposed AD would retain the current actions and require modifying the engine FCDs, installing placards, and re-identifying the FCDs with the new part numbers. This proposed AD would also revise the applicability to include all Model A319–131 and –132 airplanes; Model A320–231, –232, and –233 airplanes; and Model A321–131 and –231 airplanes. We are proposing this AD to prevent in-flight loss of an engine FCD and possible consequent damage to the airplane and hazards to persons or property on the ground. 
DATES : We must receive comments on 
this proposed AD by September 19, 2016. 
ADDRESSES : You may send comments by 
any of the following methods:

Discussion 
On August 29, 2003, we issued AD 
2003–18–06, Amendment 39–13297 (68 
FR 53501, September 11, 2003) (‘‘AD 2003–18–06’’). AD 2003–18–06 requires actions intended to address an unsafe condition on certain Airbus Model A319–131 and –132 airplanes; Model A320–231, –232, and –233 airplanes; and Model A321–131 and –231 airplanes. 
Since we issued AD 2003–18–06, we 
have received reports of additional engine FCD in-flight losses, and a new FCD front latch and keeper assembly has been developed to address this unsafe condition. 
The European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016–0053, dated March 14, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A319–131 and –132; A320–231, –232, and –233; and A321–131 and –231 airplanes. The MCAI states: 
Fan Cowl Door (FCD) losses during take-off 
were reported on aeroplanes equipped with 
IAE V2500 engines. Prompted by these occurences, [Direction Ge ´ne´rale de l’Aviation 
Civile] DGAC France issued AD 2000–444– 156(B), mandating FCD latch improvements. This [DGAC] AD was later superseded by AD 2001–381(B) [which corresponds to FAA AD 2003–18–06], requiring installation of additional fan cowl latch improvement by installing a hold open device. 
Since that [DGAC] AD was issued, further 
FCD in flight losses were experienced in service. Investigations confirmed that in all
