Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–100, 

747–100B, 747–100B SUD, 747–200B, 

747–200C, 747–200F, 747–300, 747– 

400, 747–400D, 747–400F, 747SR, and 

747SP series airplanes. This AD was 

prompted by several reports of chafing 

of the wire bundles inside the electrical 

conduit of the forward and aft boost 

pumps of the numbers 1 and 4 main fuel 

tanks due to high vibration. These wire 

bundles can chafe through the wire 

sleeving into the insulation, exposing 

the wire conductors. This AD requires 

replacing the wire bundles inside the 

electrical conduit of the forward and aft 

boost pumps of the numbers 1 and 4 

main fuel tanks with new, improved 

wire bundles inserted into conduit 

liners. This AD also requires adding a 

revision to the maintenance or 

inspection program, as applicable, to 

include critical design configuration 

control limitations (CDCCLs) for the fuel 

boost pump wiring. We are issuing this 

AD to prevent chafing of the wire 

bundles and subsequent arcing between 

the wiring and the electrical conduit 

creating an ignition source in the fuel 

tanks, which could result in a fire and 

consequent fuel tank explosion. 

DATES: This AD is effective October 31, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of October 31, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 by adding an AD 

that would apply to certain The Boeing 

Company Model 747–100, 747–100B, 

747–100B SUD, 747–200B, 747–200C, 

747–200F, 747–300, 747–400, 747– 

400D, 747–400F, 747SR, and 747SP 

series airplanes. The SNPRM published 

in the Federal Register on March 8, 

2016 (81 FR 12041) (‘‘the SNPRM’’). We 

preceded the SNPRM with a notice of 

proposed rulemaking (NPRM) that 

published in the Federal Register on 

May 1, 2015 (80 FR 24850) (‘‘the 

NPRM’’). The NPRM proposed to 

require replacing the wire bundles 

inside the electrical conduit of the 

forward and aft boost pumps of the 

numbers 1 and 4 main fuel tanks with 

new, improved wire bundles inserted 

into conduit liners. The NPRM was 

prompted by several reports of chafing 

of the wire bundles inside the electrical 

conduit of the forward and aft boost 

pumps of the numbers 1 and 4 main fuel 

tanks due to high vibration. These wire 

bundles can chafe through the wire 

sleeving into the insulation, exposing 

the wire conductors. The SNPRM 

proposed to require a revision to the 

maintenance or inspection program, as 

applicable, to include CDCCLs for the 

fuel boost pump wiring. We are issuing 

this AD to prevent chafing of the wire 

bundles and subsequent arcing between 

the wiring and the electrical conduit 

creating an ignition source in the fuel 

tanks, which could result in a fire and 

consequent fuel tank explosion. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

The Air Line Pilots Association 

International, Boeing, and United 

Airlines supported the SNPRM. 

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 SNPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the SNPRM.

1 work-hour × $85 per hour = $85 .... $0 $85 ............................. $14,960. 

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 

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.

Repair Stations; Response to Public 

Comments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; confirmation of 

effective date and response to public 

comments. 

SUMMARY: This action confirms the 

effective date and adopts as final the 

interim final rule published on July 27, 

2016, and responds to the comments 

received on that interim final rule. The 

rule removed the requirement that a 

repair station with an airframe rating 

provide suitable permanent housing to 

enclose the largest type and model 

aircraft listed on its operations 

specifications. The FAA also revised its 

general housing and facilities regulation 

to provide that a repair station’s housing 

for its facilities, equipment, materials, 

and personnel must be consistent not 

only with its ratings, but also with its 

limitations to those ratings. Finally, the 

FAA added an additional general 

purpose limited rating to cover 

maintenance work not covered by the 

existing 12 limited rating categories. 

DATES: Effective September 26, 2016. 

ADDRESSES: For information on where to 

obtain copies of rulemaking documents 

and other information related to this 

action, see ‘‘How To Obtain Additional 

Information’’ in the SUPPLEMENTARY

INFORMATION section of this document.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued an interim final rule 

on July 15, 2016 (81 FR 49158) to revise 

its repair station rules to remove the 

one-size-fits-all requirement of 

§ 145.103(b) and provide an additional 

limited rating category to cover work 

not addressed by the existing 12 

categories. These actions will assist the 

repair station industry by eliminating 

the costly housing requirement that is 

not necessary in many cases. 

Discussion of Comments 

The FAA received two comments 

from the Aeronautical Repair Station 

Association (ARSA) and Airbus. ARSA 

stated that it fully supported the 

agency’s actions as the regulations were 

unclear and needed to be updated. 

ARSA noted that although the changed 

rule still does not distinguish between 

repair stations working on completed 

aircraft and those working on airframe 

components, the removal of specified 

housing for airframe ratings will 

certainly allow for performance-based 

compliance. ARSA also requested the 

FAA consider removing § 145.61(b) in 

its entirety. ARSA asserted that it seems
