be limited for ‘‘hazardous/severe-major’’ 

failure conditions and effects due to 

safety considerations. Compliance with 

the requirements for failure conditions 

classified as ‘‘catastrophic’’ may be 

shown by analysis, and appropriate 

testing in combination with simulation 

to validate the analysis. Very limited 

flight tests in combination with 

simulation are used as a part of a 

showing of compliance for 

‘‘catastrophic’’ failure conditions. Flight 

tests are performed only in 

circumstances that use operational 

variations, or extrapolations from other 

flight performance aspects to address 

flight safety. 

These special conditions require that 

the HeliSAS AP/SAS system installed 

on an Airbus Helicopters model 

EC135P1, EC135T1, EC135P2, EC135T2, 

EC135P2+, or EC135T2+ helicopter, 

Type Certificate Number H88EU, meet 

these requirements to adequately 

address the failure effects identified by 

the FHA, and subsequently verified by 

the SSA, within the defined design 

system integrity requirements.

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 707 

airplanes, Model 720 and 720B series 

airplanes, Model 727 airplanes, and 

Model 737–100, –200, and –200C series 

airplanes. This AD was prompted by a 

report of a fire that originated near the 

first officer’s area and caused extensive 

damage to the flight deck on a different 

airplane model. This AD requires 

replacing the low-pressure oxygen hoses 

with non-conductive low-pressure 

oxygen hoses in the flight compartment. 

We are issuing this AD to prevent 

electrical current from inadvertently 

passing through an internal, anticollapse spring of the low-pressure 

oxygen hose, which can cause the lowpressure oxygen hose to melt or burn, 

leading to an oxygen-fed fire and/or 

smoke in the flight deck. 

DATES: This AD is effective September 

23, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 23, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 707 airplanes, Model 720 and 

720B series airplanes, Model 727 

airplanes, and Model 737–100, –200, 

and –200C series airplanes. The NPRM 

published in the Federal Register on 

April 23, 2014 (79 FR 22599). The 

NPRM was prompted by a report of a 

fire that originated near the first officer’s 

area and caused extensive damage to the 

flight deck on a different airplane 

model. The NPRM proposed to require 

replacing the low-pressure oxygen hoses 

with non-conductive low-pressure 

oxygen hoses in the flight compartment. 

We are issuing this AD to prevent 

inadvertent electrical current from 

passing through an internal, anticollapse spring of the low-pressure 

oxygen hose, which can cause the lowpressure oxygen hose to melt or burn, 

leading to an oxygen-fed fire and/or 

smoke in the flight deck. 

Explanation of Changes Made to This 

Final Rule 

We have changed the point-of-contact 

information for the various affected 

airplane models in paragraphs (i)(1) and 

(j) of this final rule. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 22599, April 23, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

22599, April 23, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 22599, 

April 23, 2014). 

Costs of Compliance 

We estimate that this AD affects 530 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:

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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–215–6B11 

(CL–215T Variant), and CL–215–6B11 

(CL–415 Variant) airplanes. This AD 

was prompted by several reports 

indicating that shorter nacelle strut 

bushings were inadvertently installed 

on certain airplanes. This AD requires a 

general visual inspection of the left and 

right nacelle upper strut bushings; 

installation of the bolts and preload 

indicating (PLI) washers, if necessary; 

and replacement of the bushing or 

repair of the bushing installation, if 

necessary. We are issuing this AD to 

detect and correct inadequate nacelle 

strut bushings, which provide 

insufficient engagement in the strut fork 

end, and could deform under the 

bearing load and lead to the failure of 

the joint. 

DATES: This AD becomes effective
