Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-8435; Directorate Identifier 2015-NM-049-AD; 
Amendment 39-18594; AD 2016-15-03]
RIN 2120-AA64


Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD 
was prompted by reports of operator inability to open the main 
passenger door following severe hot soak conditions. This AD requires 
the incorporation of a new configuration to the passenger door external 
handle detent to enhance the performance across the full range of the 
airplane operating temperatures. We are issuing this AD to prevent 
thermal expansion and permanent deformation at severe hot soak 
conditions, creating high friction between the spring pot housing and 
the slider that could result in inability to open the main passenger 
door and impede evacuation in the event of an emergency.

DATES: This AD is effective August 31, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 31, 
2016.

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 Bombardier, Inc. 
Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the 
Federal Register on January 13, 2016 (81 FR 1584) (``the NPRM''). The 
NPRM was prompted by reports of operator inability to open the main 
passenger door following severe hot soak conditions. The NPRM proposed 
to require the incorporation of a new configuration to the passenger 
door external handle detent to enhance the performance across the full 
range of the airplane operating temperatures. We are issuing this AD to 
prevent thermal expansion and permanent deformation at severe hot soak 
conditions, creating high friction between the spring pot housing and 
the slider that could result in inability to open the main passenger 
door and impede evacuation in the event of an emergency.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-03, dated March 13, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model BD-700-1A10 and BD-
700-1A11 airplanes. The MCAI states:

    There have been reports where operators experienced an inability 
to open the main passenger door following severe hot soak 
conditions.
    Investigation determined that the nylon slider in the plunger 
assembly of the door handle is susceptible to thermal expansion

[[Page 49157]]

and permanent deformation at severe hot soak conditions, creating 
high friction between the spring pot housing and the slider.
    This condition, if not corrected, could result in an inability 
to open the main passenger door and could impede evacuation in the 
event of an emergency.
    This [Canadian] AD mandates the incorporation of a new 
configuration to the passenger door external handle detent to 
enhance the performance across the full range of the aeroplanes 
operating temperatures.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
8435.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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 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.

Related Service Information Under 1 CFR Part 51

    Bombardier issued the following service Information:
     Bombardier Service Bulletin 700-1A11-52-021, Revision 01, 
dated February 3, 2015.
     Bombardier Service Bulletin 700-52-044, Revision 01, dated 
February 3, 2015.
     Bombardier Service Bulletin 700-52-5008, Revision 01, 
dated February 3, 2015.
     Bombardier Service Bulletin 700-52-6008, Revision 01, 
dated February 3, 2015.
    The service information describes procedures to incorporate a new 
configuration to the passenger door external handle detent. 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.

Costs of Compliance

    We estimate that this AD affects 60 airplanes of U.S. registry.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $20,400, or $340 per product.

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 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 the 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.
