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

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

**SUMMARY :**  We propose to supersede Airworthiness Directive (AD) 2012–19– 11, which applies to certain The Boeing Company Model 737 airplanes. AD 2012–19–11 currently requires incorporating design changes to improve the reliability of the cabin altitude warning system by installing a redundant cabin altitude pressure switch, replacing the aural warning module (AWM) with a new or reworked AWM, and changing certain wire bundles or connecting certain previously capped and stowed wires as necessary. For certain airplanes, AD 2012–19–11 also requires prior or concurrent incorporation of related design changes by modifying the instrument panels, installing light assemblies, modifying the wire bundles, and installing a new circuit breaker, as necessary. Since we issued AD 2012– 19–11, we have determined that certain airplanes were not included in the requirement to incorporate related design changes. This proposed AD would add, for certain airplanes, a requirement to incorporate related design changes. This proposed AD also, for certain airplanes, no longer gives credit for accomplishing certain previous actions. We are proposing this AD to prevent the loss of cabin altitude warning, which could delay flightcrew recognition of a lack of cabin pressurization, and could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.

**DATES :**  We must receive comments on this proposed AD by September 12,

2014.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following

Discussion

On September 19, 2012, we issued AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), for certain The Boeing Company Model 737 airplanes. AD 2012–19–11 requires incorporating design changes to improve the reliability of the cabin altitude warning system by installing a redundant cabin altitude pressure switch, replacing the AWM with a new or reworked AWM, and changing certain wire bundles or connecting certain previously capped and stowed wires as necessary. For certain airplanes, AD 2012–19–11 also requires prior or concurrent incorporation of related design changes by modifying the instrument panels, installing light assemblies, modifying the wire bundles, and installing a new circuit breaker, as necessary. AD 2012–19–11 resulted from a report of a flightcrew not receiving an aural warning during a lack of cabin pressurization event. We issued AD 2012–19–11 to prevent the loss of cabin altitude warning, which could delay flightcrew recognition of a lack of cabin pressurization, and could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.

Other Related Rulemaking

The concurrent actions for AD 2012– 19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), are the primary corrective actions for AD 2011–03–14, Amendment 39–16598 (76 FR 6529, February 7, 2011), and AD 2013–02–05, Amendment 39–17326 (78 FR 6202, January 30, 2013). AD 2011–03–14 and AD 2013–02–05 provide the necessary wiring configuration to perform the
corrective actions for AD 2012–19–11. AD 2011–03–14 (for certain Model 737– 100, –200, –200C, –300, –400, and –500 series airplanes) and AD 2013–02–05 (for certain Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes) were issued to prevent failure of the flightcrew to recognize and react to a valid cabin altitude warning horn, which could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.

Actions Since AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), Was Issued

Since we issued AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), we have reviewed new
service information for the actions required by paragraph (g) of AD 2012– 19–11, which refers to Boeing Special
Attention Service Bulletin 737–21– 1164, Revision 1, dated May 17, 2012, as one of the appropriate sources of service information. Boeing Special
Attention Service Bulletin 737–21– 1164, Revision 2, dated August 23, 2013, provides essentially the same procedure for accomplishing the actions, except for certain airplanes, Boeing Special Attention Service Bulletin 737–21–1164, Revision 2, dated August 23, 2013, specifies to contact the manufacturer for the installation and replacement of certain wire bundles.

We also have reviewed new service
information for the concurrent actions required by paragraph (h) of AD 2012– 19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), which refers to Boeing Alert Service Bulletin 737– 31A1325, dated January 11, 2010; and Boeing Alert Service Bulletin 737– 31A1332, Revision 3, dated March 28, 2012; as the appropriate sources of service information. Boeing Alert Service Bulletin 737–31A1325, Revision 1, dated July 5, 2012; and Boeing Alert Service Bulletin 737–31A1332, Revision 4, dated October 31, 2013; provide essentially the same procedures for accomplishing the concurrent actions, except, for certain airplanes, Boeing Alert Service Bulletin 737–31A1325, Revision 1, dated July 5, 2012, specifies
to contact the manufacturer for modification, installation, and repair instructions. Boeing Alert Service Bulletin 737–31A1332, Revision 4, dated October 31, 2013, also specified that airplanes having line numbers YA091 through YA097 were inadvertently removed from Boeing Alert Service Bulletin 737–31A1332, Revision 3, dated March 28, 2012, and are now included in Group 1 airplanes as identified in Boeing Alert Service Bulletin 737–31A1332, Revision 4, dated October 31, 2013.

In addition, we are also correcting a typographical error in paragraph (i)(1) of AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), which refers to paragraph (h) of that AD; paragraph (i)(1) of AD 2012–19–11 should refer to paragraph (g) of that AD. Operators that accomplished Boeing Special Attention Service Bulletin 737– 21–1165, Revision 1, dated July 16, 2010, get credit for the actions in paragraph (g) of this AD; operators cannot get credit for the concurrent actions required by paragraph (h) of this AD because they cannot accomplish the concurrent actions using Boeing Special
Attention Service Bulletin 737–21– 1165, Revision 1, dated July 16, 2010.

We have revised paragraphs (i)(2) through (i)(4) of AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), to specify certain airplane variable numbers to clearly identify the airplanes that are allowed to receive credit for previous actions using
certain service information and to match the information specified in AD 2013– 02–05, Amendment 39–17326 (78 FR 6202, January 30, 2013). The airplanes identified in paragraphs (j)(2) through (j)(4) of this proposed AD match the airplanes specified in paragraphs (i)(1) through (i)(3) of AD 2013–02–05; these


### 43985 Federal Register / Vol. 79, No. 145 / Tuesday, July 29, 2014 / Proposed Rules

paragraphs give credit for doing actions specified in Boeing Alert Service Bulletin 737–31A1332, Revision 1, dated June 24, 2010; and Boeing Alert Service Bulletin 737–31Al332, Revision 2, dated August 18, 2011.

However, airplanes having variable numbers YA001 through YA008, YA251, YA501 through YA508, and YC321 through YC325, were allowed to take credit for actions as specified in paragraph (i)(2) and (i)(3) of AD 2012– 19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012). Airplanes having variable numbers YA001 through YA008, YA251, YA501 through YA508, and YC321 through YC325 are now excluded from the credit for doing certain actions given in paragraphs (j)(2) and (j)(3) of this proposed AD; therefore, we have provided a new compliance time for those airplanes in paragraph (i)
of this AD.

Relevant Service Information

We reviewed the following service
information:

• Boeing Special Attention Service Bulletin 737–21–1164, Revision 2, dated August 23, 2013. • Boeing Alert Service Bulletin 737– 31A1325, Revision 1, dated July 5, 2012.

• Boeing Alert Service Bulletin 737– 31A1332, Revision 4, dated October 31,

2013.

For information on the procedures and compliance times, see this service
information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014–

0487.

FAA’s Determination

We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would retain all requirements of AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012). This proposed AD would add, for certain airplanes, a requirement to incorporate related design changes. This proposed AD also, for certain airplanes, no longer gives credit for accomplishing certain previous actions.

Differences Between This Proposed AD
and the Service Information

Boeing Special Attention Service Bulletin 737–21–1164, Revision 2, dated August 23, 2013; and Boeing Alert Service Bulletin 737–31A1325, Revision 1, dated July 5, 2012; specify to contact
the manufacturer for instructions on how to repair certain conditions, but this proposed AD would require repairing those conditions in one of the following ways:

• In accordance with a method that

we approve; or

• Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom
we have authorized to make those findings.

Costs of Compliance

We estimate that this proposed AD affects 1,618 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Install a redundant cabin altitude pressure switch, replace the AWM with a new or reworked AWM, change certain wire bundles or connect certain capped and stowed wires [retained actions from AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), for 1,618 airplanes]. Up to 62 work–hours × $85 per hour = up to $5,270. $33,576 Up to $38,846. Up to $62,852,828.

Modify the instrument panels, install light assemblies,

modify the wire bundles, and install a new circuit breaker (concurrent requirements) [retained actions from AD 2012–19–11, Amendment 39–17206 (77 FR 60296, October 3, 2012), for 1,596 airplanes]. Up to 92 work–hours × $85 per hour = up to $7,820. 5,292 Up to $13,112. Up to $20,926,752.

Modify the instrument panels, install light assemblies,

modify the wire bundles, and install a new circuit breaker (concurrent requirements) [new actions for 22 airplanes]. Up to 92 work–hours × $85 per hour = up to $7,820. 5,292 Up to $13,112. Up to $288,464.

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 have 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 that the 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.

**Commission**

**18 CFR Part 40**

**[Docket No. RM14–8–000]**

**Protection System Maintenance Reliability Standard** 

**AGENCY :**  Federal Energy Regulatory Commission, Energy.

**ACTION :**  Notice of proposed rulemaking.

**SUMMARY :**  Pursuant to the section regarding Electric Reliability of the Federal Power Act, the Commission proposes to approve a revised Reliability Standard, PRC–005–3 (Protection System and Automatic Reclosing Maintenance). In addition, the Commission proposes to approve one new definition and six revised definitions referenced in the proposed Reliability Standard, the assigned
violation risk factors and violation severity levels, and NERC’s proposed implementation plan. Consistent with Order No. 758, the proposed Reliability Standard requires applicable entities to test and maintain certain autoreclosing relays as part of a protection system maintenance program. The Commission also proposes to direct NERC to submit a report based on actual performance data, and simulated system conditions from planning assessments, two years after the effective date of the proposed standard, which addresses whether the proposed Reliability Standard applies to an appropriate set of autoreclosing relays that can affect Bulk-Power System reliability. Further, the Commission proposes to direct NERC to modify the proposed Reliability
Standard to include maintenance and testing of supervisory relays, as
discussed below.

**DATES :**  Comments are due September

29, 2014.
