Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–8 

series airplanes. This AD requires an 

inspection to determine if all oxygen 

components in the passenger oxygen 

system are installed, installation of new 

o-rings, and corrective actions if 

necessary. This AD was prompted by a 

report that oxygen tube couplings in the 

passenger oxygen system could be 

missing or incorrectly installed. We are 

issuing this AD to detect and correct 

oxygen leaks from oxygen tube 

couplings in the passenger oxygen 

system, which could result in depletion 

of emergency oxygen at a faster rate than 

expected, reduce the passengers’ and 

crews’ protection from hypoxia at 

elevated cabin altitudes, and increase 

the risk of a fire. 

DATES: This AD is effective April 15, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 15, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We have determined that some Model 

747–8 series airplanes could have 

oxygen components missing or 

incorrectly installed at oxygen tube 

couplings attached to the outboard 

stowage bin support assemblies. The 

manufacturer believes that these 

airplanes were delivered with the 

correct configuration of oxygen 

components. However, because of an 

error in an engineering drawing and 

related parts list, which omitted part 

number call-outs for some oxygen 

components, we want to be certain 


jstallworth on DSK7TPTVN1PROD with RULES
Federal Register / Vol. 81, No. 62 / Thursday, March 31, 2016 / Rules and Regulations 18465 

installations are correct and prevent 

incorrect installation during subsequent 

rework of the oxygen tubing 

components. This condition, if not 

corrected, could result in oxygen leaks 

from oxygen tube couplings in the 

passenger oxygen system, which could 

result in depletion of emergency oxygen 

at a faster rate than expected, reduce the 

passengers’ and crews’ protection from 

hypoxia at elevated cabin altitudes, and 

increase the risk of a fire. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Special 

Attention Service Bulletin 747–35– 

2132, dated June 8, 2015. The service 

information describes procedures for 

inspection of passenger oxygen coupler 

assemblies for missing oxygen 

components, installation of o-rings, and 

corrective actions. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section. 

FAA’s Determination 

We are issuing 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. 

AD Requirements 

This AD requires accomplishing the 

actions identified in the service 

information identified previously. 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–2016– 

5033. 

The phrase ‘‘corrective actions’’ is 

used in this AD. ‘‘Corrective actions’’ 

are actions that correct or address any 

condition found. Corrective actions in 

an AD could include, for example, 

repairs. 

This AD also requires sending the 

inspection results to the Manager, 

Seattle Aircraft Certification Office, 

FAA. 

FAA’s Justification and Determination 

of the Effective Date 

There are no products of this type 

currently registered in the United States. 

However, this rule is necessary to 

ensure that the described unsafe 

condition is addressed if any of these 

products are placed on the U.S. Register 

in the future. Therefore, we find that 

notice and opportunity for prior public 

comment are unnecessary and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2016–5033; Directorate Identifier 2015– 

NM–118–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this AD. We will consider all 

comments received by the closing date 

and may amend this AD because of 

those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD affects 0 

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 

Cost on U.S. 

operators 

Inspection ................... 8 work-hours × $85 per hour = $680 .................................................. $0 $680 $0 

Reporting ................... 1 work-hour × $85 per hour = $85 ...................................................... 0 85 0 

We estimate the following costs to do 

any necessary corrective actions that 

will be required based on the results of 

the inspection. We have no way of 

determining the number of aircraft that 

might need these repairs: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Corrective Action .......................................................... 8 work-hours × $85 per hour = $680 ........................... $6,888 $7,568 

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. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591, ATTN: Information 

Collection Clearance Officer, AES–200. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 


jstallworth on DSK7TPTVN1PROD with RULES
18466 Federal Register / Vol. 81, No. 62 / Thursday, March 31, 2016 / Rules and Regulations 

rules on aviation safety. Subtitle I,

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to remove AD 2014–07–04R1, 

Amendment 39–17964 (79 FR 54893, 

September 15, 2014) and add a new AD. 

AD 2014–07–04R1 applied to certain 

serial-numbered Sikorsky S92A 

helicopters and required repetitively 

inspecting the upper deck area for 

incorrectly installed clamps and for 

chafing between the electrical wires and 

hydraulic lines. 

The NPRM published in the Federal 

Register on September 25, 2015 (80 FR 

57751). The NPRM was prompted by an 

alteration developed by Sikorsky that 

separates and re-routes the engine inlet 

feeder lines. The NPRM proposed to 

require this alteration to prevent chafing 

between the electrical lines and 

hydraulic hoses, which could result in 

a fire in an area of the helicopter 

without extinguishing capability and 

subsequent loss of control of the 

helicopter. 

Since the NPRM was issued, the 

mailing address for the Boston Aircraft 

Certification Office has changed. We 

have revised this contact information in 

this final rule to reflect the new mailing
