B. Issues on Which DOE Seeks Comment

Although DOE welcomes comments on any aspect of this request for information, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues:

1. Information on the effects of utility programs designed to reduce peak energy demand by heating water only during off-peak times and storing the water for use during peak demand periods. In particular, DOE is interested in information on the penetration of residential water heater load shifting programs throughout the U.S. (i.e., what percentage of total water heaters installed are used in these programs), the economic benefits of such programs to consumers, and the energy impacts (if any) or other National benefits that are achieved through the use of such

programs.

2. Information on the effects of the amended energy conservation standards for electric storage water heaters with rated storage volumes above 55 gallons on utility programs designed to reduce peak energy demand by heating water only during off-peak times and storing the water for use during peak demand periods.

3. Information on capacity or other performance-related feature(s) for residential water heaters which other water heaters do not have that are used in demand-response programs and whether such feature(s) justifies a separate standard from that which will apply to other electric water heaters with rated storage volumes above 55 gallons.

4. Information on potential solutions that would resolve the concerns of utilities that administer load shifting programs for residential water heaters that require the use of large-volume electric storage water heaters, including the potential approaches identified in this RFI.

Issued in Washington, DC, on June 6, 2012. Kathleen B. Hogan, Deputy Assistant Secretary for Energy Efficiency, Energy Efficiency and Renewable Energy.

Discussion

We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was published in the Federal Register on August 8, 2011 (76 FR 48045). That earlier NPRM proposed to require actions intended to address the unsafe condition for the products listed above.

Since that NPRM (76 FR 48045, August 8, 2011) was issued, TECNAM found that the replacement part number could cause a deformation of the


### 35305 Federal Register / Vol. 77, No. 114 / Wednesday, June 13, 2012 / Proposed Rules

emergency accumulator, so TECNAM has developed a modification for the landing gear extension emergency accumulator and revised the service information to include instructions for that modification.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2012–0043, dated March 19, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

During a pre-flight inspection of a P2006T aeroplane, the lower skin of the fuselage aft tail cone was found damaged. This damage was caused by the lower lid of the LG emergency accumulator, which had detached from the LG emergency accumulator, violently hitting the lower skin of the fuselage aft tail cone and damaging the accumulator cylinder.

This condition, if not detected and corrected, could impair the aeroplane structural integrity and jeopardize the LG emergency extension in case of system failure in normal mode.

For the reasons described above, EASA issued Emergency AD 2011–0063–E to require a one-time inspection of the LG emergency accumulator cylinder for cracks, deformation or oil leakage and, depending on findings, the accomplishment of the applicable corrective actions.

After that AD was issued, Costruzioni Aeronautiche TECNAM developed a modification (MOD 2006–108) and published Service Bulletin (SB) SB–048–CS Revision 1, dated 06 July 2011, that contained the instructions for that modification. Prompted by this development, EASA issued PAD 11– 070 for consultation until 16 August 2011, proposing to require incorporation of this modification on all affected aeroplanes, and to require certain post-modification repetitive inspections.

During the consultation period of PAD 11– 070, an operator who had applied Costruzioni Aeronautiche TECNAM SB–048– CS on his aeroplane, reported finding abnormal deformation of the emergency accumulator, to such an extent that it would jeopardize the LG emergency extension in case of system failure in normal mode. To address this additional safety concern, Costruzioni Aeronautiche TECNAM issued SB–068–CS which contains instructions to inspect post-modification aeroplanes.

For the reasons described above, EASA AD 2011–0153–E retained the requirements of EASA AD 2011–0063–E, which was superseded, and required modification of the landing gear emergency accumulator by installation of safety rings and repetitive inspections after modification. In addition, prompted by the recent post-modification findings, EASA AD 2011–0153–E reduced the compliance time for the modification as originally proposed and required additional first-flight-of-the-day repetitive inspections for the LG emergency accumulator cylinder and replacement of the LG emergency accumulator if cracks, deformation, or oil leakage is detected. AD Revision 2011–0153R1 was issued in order to allow Pilot-Owners to accomplish the daily pre-flight inspection of the modified LG emergency accumulator.

After that AD Revision, Costruzioni Aeronautiche TECNAM designed a new LG emergency accumulator part number 26–9– 9500–000, identified as modification MOD 2006–121, and published SB–080–CS dated 02 January 2012, which contains instructions for replacement and installation of the newly designed LG emergency accumulator.

This AD, which supersedes EASA AD 2011–0153R1, requires the installation of the new landing gear emergency accumulator part number 26–9–9500–000, as well as to inspect after the installation the LG emergency accumulator and the LG retraction/extension system.
You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Costruzioni Aeronautiche TECNAM has issued Service Bulletin No. SB 80– CS, dated January 2, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the 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.

Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on the proposed AD. Costs of Compliance

We estimate that this proposed AD will affect 7 products of U.S. registry. We also estimate that it would take about 7 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,300 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $13,265, or $1,895 per product. 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. 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. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**RIN 2120–AA64**

**Airworthiness Directives; Bell Helicopter Textron, Inc. Helicopters** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for the Bell Helicopter Textron, Inc. (BHTI) Model 205A, 205A–1, and 205B helicopters with certain starter/generator power cable assemblies (power cable assemblies). This proposed AD is prompted by the determination that the power cable assembly connector (connector) can deteriorate, causing a short in the connector that may lead to a fire. This AD would require replacing the power cable assemblies and their associated parts, and performing continuity readings. We are proposing this AD to prevent a short in the connector that may lead to a fire in the starter/generator, smoke in the cockpit that reduces visibility, and subsequent loss of helicopter control.
