2016-07576. Airworthiness Directives; The Boeing Company Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2013-26-08 for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 required 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. This new AD adds airplanes to the applicability. AD 2013-26-08 resulted from reports of arcing and smoke at the left number 2 window in the flight deck. This AD was prompted by a determination that additional airplanes are subject to the same identified unsafe condition. We are issuing this AD to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.

DATES:

This AD is effective May 12, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 10, 2014 (79 FR 545, January 6, 2014).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013-26-08, Amendment 39-17717 (79 FR 545, January 6, 2014) (“AD 2013-26-08”). AD 2013-26-08 applied to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. The NPRM published in the Federal Register on January 23, 2015 (80 FR 3527) (“the NPRM”). AD 2013-26-08 resulted from reports of arcing and smoke at the left number 2 window in the flight deck. The NPRM was prompted by a determination that additional airplanes are subject to the same identified unsafe condition. The NPRM proposed to continue to require 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. The NPRM also proposed to add airplanes to the applicability. We are issuing this AD to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment.

Support for the NPRM

Boeing stated that it supports the NPRM as written.

Effect of Winglets on Accomplishment of the Proposed Actions

Aviation Partners Boeing stated that the installation of winglets per Supplemental Type Certificate (STC) ST00830SE (http://rgl.faa.gov/​Regulatory_​and_​Guidance_​Library/​rgstc.nsf/​0/​184de9a71ec3fa5586257eae00707da6/​$FILE/​ST00830SE.pdf) does not affect the accomplishment of the manufacturer's service instructions.

We agree with the commenter that STC ST00830SE (http://rgl.faa.gov/​Regulatory_​and_​Guidance_​Library/​rgstc.nsf/​0/​184de9a71ec3fa5586257eae00707da6/​$FILE/​ST00830SE.pdf) does not affect the accomplishment of the manufacturer's service instructions. Therefore, the installation of STC ST00830SE does not affect the ability to accomplish the actions required by this AD. We have not changed this AD in this regard.

Comment Regarding Applicability

United Airlines (UAL) stated that it found it curious that the technical compliance mandated in AD 2013-26-08 was per Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, whereas the airplane applicability in AD 2013-26-08 was based on Boeing Special Attention Service Bulletin 737-30-1058, Revision 4, dated November 3, 2011. UAL stated that, consequently, it anticipated further regulatory action that would include the Group 3 airplanes specified in Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, and has acted accordingly. UAL also stated that, since it was already planning accomplishment on the Group 3 airplanes, the only impact to it will be to change the AD number on the compliance documentation. UAL stated that it has no further comments at this time.

We acknowledge UAL's comment. No change to this AD is necessary.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

Costs of Compliance

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

We estimate the following costs to comply with this AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Number of airplanes	Cost on U.S. operators
Keyway inspection and installation (Group 1, Configuration 1 airplanes) [actions retained from AD 2013-26-08]	6 work-hours × $85 per hour = $510	$1,608	$2,118	712	$1,508,016.
Adjustment of receptacles (Group 1, Configuration 2, Group 2, and Group 3 airplanes) [actions retained from AD 2013-26-08]	4 work-hours × $85 per hour = $340	0	340	410	139,400.
Coil cord inspection (Group 1, Configuration 3, and Group 2 airplanes) [actions retained from AD 2013-26-08]	1 work-hour × $85 per hour = $85 per coil cord	0	85 per coil cord	404	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 coil cord inspection. We have no way of determining the number of aircraft that might need these replacements:

On-Condition Costs

Action	Labor cost	Parts cost	Cost per product
Replacement	3 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Is not a “significant rule” under 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.
