Airworthiness Directives; Bae Systems (Operations) Limited 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all Bae 
Systems (Operations) Limited Model BAe 146 series airplanes and Model 
Avro 146-RJ series airplanes. This AD was prompted by reports of excess 
solder deposited during overhaul on the frangible plug of a fire 
extinguisher, which prevented the release of the extinguishant. This AD 
requires a one-time inspection of certain engine and auxiliary power 
unit (APU) fire extinguishers to determine if the fire extinguishers 
are affected by excessive solder and corrective actions if necessary. 
We are issuing this AD to prevent the failure of a fire extinguisher to 
discharge, which reduces the ability of the fire protection system to 
extinguish fires in the engine or APU fire zones, possibly resulting in 
damage to the airplane and injury to the passengers.

DATES: This AD becomes effective March 14, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 14, 
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 all Bae Systems 
(Operations) Limited Model BAe 146 series airplanes and Model Avro 146-
RJ series airplanes. The NPRM published in the Federal Register on 
September 25, 2013 (78 FR 58960). The NPRM was prompted by reports of 
excess solder deposited during overhaul on the frangible plug of a fire 
extinguisher, which prevented the release of the extinguishant. The 
NPRM proposed to require a one-time inspection of certain engine and 
auxiliary power unit (APU) fire extinguishers to determine if the fire 
extinguishers are affected by excessive solder and corrective actions 
if necessary. We are issuing this AD to prevent the failure of a fire 
extinguisher to discharge, which reduces the ability of the fire 
protection system to extinguish fires in the engine or APU fire zones, 
possibly resulting in damage to the airplane and injury to the 
passengers.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0126R1, dated September 10, 2012 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    A fire handle on a BAe 146 aeroplane was operated on the ground 
as a precautionary measure after the throttle cable on the affected 
engine failed, due to corrosion. The extinguisher failed to 
discharge.
    Investigation results revealed that excess solder, which had 
been deposited during overhaul on the frangible plug of the 
extinguisher, prevented the release of the extinguishant. Prompted 
by this report, Kidde Graviner, the fire extinguisher manufacturer, 
identified four further extinguishers of similar design that had the 
same issue.
    This condition, if not detected and corrected, could result in 
the failure of a fire bottle to discharge, which reduces the ability 
of the fire protection system to extinguish fires in the engine or 
Auxiliary Power Unit (APU) fire zones, possibly resulting in damage 
to the aeroplane and injury to the occupants.
    For the reasons described above, EASA issued AD 2012-0126 to 
require a one-time inspection of the affected Part Number (P/N) 
57333 engine and APU fire extinguishers. In addition, this [EASA] AD 
prohibited installation of a fire extinguisher, unless it has passed 
the inspection as required by [EASA] AD 2012-0126.
    Revision 1 of this [EASA] AD is issued to clarify that new 
extinguishers P/N 57333 may be fitted with no additional inspection 
required by this [EASA] AD.

    Required actions include installing a new unit or overhauling the 
unit if any solder is found during the inspection.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0793-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 58960, September 
25, 2013) 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 (78 FR 58960, September 25, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 58960, September 25, 2013).

Costs of Compliance

    We estimate that this AD affects 1 airplane of U.S. registry.
    We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD on U.S. operators to be $85, or $85 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.
