Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2013-26-08, which applies to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 currently requires inspecting the orientation of both sides of the coil cord connector keyways of the number 2 windows on the flight deck; re-clocking the connector keyways, if necessary; and replacing the coil cord assemblies on both number 2 windows on the flight deck. Since we issued AD 2013-26-08, we have determined that additional airplanes are subject to the identified unsafe condition. This proposed AD would add airplanes to the applicability. We are proposing this AD Start Printed Page 3528to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.

DATES:

We must receive comments on this proposed AD by March 9, 2015.

Discussion

On December 20, 2013, we issued AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014), for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 requires inspecting the orientation of both sides of the coil cord connector keyways of the number 2 windows on the flight deck; re-clocking the connector keyways, if necessary; and replacing the coil cord assemblies on both number 2 windows on the flight deck. AD 2013-26-08 resulted from reports of arcing and smoke at the left number 2 window in the flight deck. We issued AD 2013-26-08 to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.

Actions Since AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014) Was Issued

In AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014), a commenter to the SNPRM (77 FR 41931, July 17, 2012) requested that we add additional airplanes to the applicability. We determined that further delay of AD 2013-26-08 was not appropriate in light of the identified unsafe condition that existed on the airplanes specified in the applicability of AD 2013-26-08. We stated that we might consider additional rulemaking in the future. We now have determined that further rulemaking is indeed necessary, and this proposed AD follows from that determination.

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 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014). This proposed AD would add Group 3 airplanes, as identified in Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, to the applicability.

Costs of Compliance

We estimate that this proposed AD affects 718 airplanes of U.S. registry.

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

Estimated Costs

ActionLabor costParts costCost per productNumber of airplanesCost on U.S. operators
Keyway inspection and installation (Group1, Configuration 1 airplanes) [actions retained from AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014)]6 work-hours × $85 per hour = $510$1,608$2,118712$1,508,016.
Adjustment of receptacles (Group 1, Configuration 2, Group 2, and Group 3 airplanes) [actions retained from AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014)]4 work-hours × $85 per hour = $340$0$340410$139,400.
Start Printed Page 3529
Coil cord inspection (Group 1, Configuration 3, and Group 2 airplanes) [actions retained from AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014)]1 work-hour × $85 per hour = $85 per coil cord$0$85 per coil cord404$34,340 per coil cord.

We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these replacements:

On-Condition Costs

ActionLabor costParts costCost per product
Replacement3 work-hours × $85 per hour = $255 per coil cord assembly$1,735 per coil cord assembly$1,990 per coil cord assembly.

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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.

(k) Exceptions to Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, Dated April 24, 2013

(1) This paragraph restates the provisions of paragraph (j)(1) of AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014), with no changes. In the circuit breaker tables of the Work Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, the panel number for circuit breaker C00393 is incorrectly identified as “P6-12.” The correct panel number reference for circuit breaker C00393, “WINDOW HEAT POWER RIGHT SIDE,” is P6-11.

The correct description for Part 3 of the Work Instructions is “PART 3: COIL CORD INSPECTION AND REPLACEMENT IF DAMAGE IS FOUND.”

(3) This paragraph restates the provisions of paragraph (j)(3) of AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014), with no changes. In Figures 13 and 14, in paragraph 3.B. of the Work Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, the note before the step tables misidentifies certain parts and airplane groups. The note should read:

NOTE: Group 1 and Group 2 airplanes have the connector receptacle identified as D10572. Group 3 airplanes have the connector receptacle identified as D10560. Except for Group 1 airplanes, a wire diagram change is not necessary and not shown in this service bulletin.
