14 CFR Part 39

[Docket No. FAA-2014-0252; Directorate Identifier 2013-NM-213-AD; 
Amendment 39-17933; AD 2014-16-09]
RIN 2120-AA64

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, anti-collapse spring of the low-pressure oxygen hose, which 
can cause the low-pressure 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, anti-
collapse spring of the low-pressure oxygen hose, which can cause the 
low-pressure 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.
