Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, issued EASA AD No. 2012–0216, dated October 18, 2012, to correct an unsafe condition for ECD Model MBB– BK 117 C–2 helicopters. EASA advises that the autopilot (AP) of a Model MBB– BK 117 C–2 helicopter failed in flight with ‘‘ACTUATOR’’ and ‘‘BACKUP SAS’’ messages appearing on the caution and advisory display, ‘‘AP’’ illuminated in red on the warning unit, and Y (Yaw actuator) and P (pitch actuator) on the primary flight display. E:\FR\FM\24MYR1.SGM 24MYR1 Federal Register / Vol. 78, No. 101 / Friday, May 24, 2013 / Rules and Regulations With the AP switched off, cautions ‘‘YAW SAS’’ and ‘‘BACKUP SAS’’ appeared on the caution and advisory display. When the AP was switched on again, the ‘‘YAW SAS’’ caution stopped appearing while ‘‘BACKUP SAS’’ still appeared, EASA reports. According to EASA, an investigation indicates that a short circuit on the yaw Smart Electro-Mechanical Actuator (SEMA) ‘‘ACTIV’’ input to ground led to the seizure of all five SEMA units. EASA advises that this condition, if not corrected, ‘‘combined with an inoperative Autotrim in Pitch or Roll, or combined with an inoperative Autotrim in Cyclic and Yaw axis,’’ could significantly reduce the pilot’s reaction time to stabilize the helicopter, resulting in possible loss of helicopter control. EASA reports that this situation could occur when operating under IFR or night VFR. FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. mstockstill on DSK4VPTVN1PROD with RULES Related Service Information Eurocopter has issued Alert Service Bulletin MBB–BK117 C–2–22A–013, dated October 12, 2012 (ASB), which states that the autopilot and caution indication systems failed during flight. Eurocopter’s initial analysis revealed that a short circuit occurred within a SEMA, causing the SEMAs’ adjustment travel to ‘‘freeze.’’ If this failure is combined with a failure of the autotrim system in the pitch, roll, or yaw axis, it could reduce the pilot’s reaction time to stabilize the helicopter ‘‘in an unacceptable way.’’ The ASB requires revision of sections of the master minimum equipment list (MMEL) with respect to inoperative TRIM-function to restrict dispatch conditions. AD Requirements Within 25 hours time-in-service (TIS) or 30 days, whichever comes first, this AD requires you to insert a statement into the operating limitations section of the MBB–BK 117C–2 Rotorcraft Flight Manual under paragraph 2.2, Kinds of Operations, prohibiting operation under IFR or Night VFR with the autotrim inoperative in pitch or roll, or combined VerDate Mar<15>2010 17:44 May 23, 2013 Jkt 229001 inoperative autotrim in cyclic and yaw axis. Differences Between This AD and the EASA AD The EASA AD requires revising the operator’s minimum equipment list (MEL). We make no requirement regarding the MEL. Costs of Compliance We estimate that this AD will affect 109 helicopters of U.S. Registry and that labor costs will average $85 a work hour. Based on these assumptions, we expect the following costs: Placing the AD in the limitations section of the RFM will require a 0.2 work-hour and no parts for a cost of $17 per helicopter, $1,853 for the U.S. fleet. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule, because the required corrective actions must be accomplished within 25 hours TIS or 30 days. As the ECD Model MBB–BK 117 C–2 helicopter is used in such areas as emergency medical service, newsgathering, and law enforcement, this is a short time period. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impractical and contrary to the public interest and that good cause exists for making this amendment effective in less than 30 days. 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 PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 31395 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, 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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUMMARY: Effective date, 0901 UTC, August 22, 2013. The Director of the Federal Register approves this incorporation by reference action under 1 CFR Part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments. FOR FURTHER INFORMATION CONTACT: Richard Roberts, Federal Aviation Administration, Operations Support Group, Western Service Center, 1601 Lind Avenue SW., Renton, WA 98057; telephone (425) 203–4517. SUPPLEMENTARY INFORMATION: DATES: History On December 21, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to amend controlled airspace at Portland-Hillsboro, OR (77 FR 75593). This action was initiated by a biennial review of the airspace. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraphs 5000, 6002 and 6004, respectively, of FAA Order 7400.9W dated August 8, 2012, and effective September 15, 2012, which is PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order. The Rule This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by modifying Class E airspace designated as an extension to Class D surface area. The size of the Class E airspace to the northwest has been reduced, the Class E airspace to the south removed, and additional Class E airspace created south southeast of the PortlandHillsboro Airport. The geographic coordinates of the airport also are updated to coincide with the FAA’s aeronautical database. This action enhances the safety and management of IFR operations. The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (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); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies controlled airspace at PortlandHillsboro Airport, Portland-Hillsboro, OR. Environmental Review The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ E:\FR\FM\24MYR1.SGM 24MYR1

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, issued EASA AD No. 
2012-0216, dated October 18, 2012, to correct an unsafe condition for 
ECD Model MBB-BK 117 C-2 helicopters. EASA advises that the autopilot 
(AP) of a Model MBB-BK 117 C-2 helicopter failed in flight with 
``ACTUATOR'' and ``BACKUP SAS'' messages appearing on the caution and 
advisory display, ``AP'' illuminated in red on the warning unit, and Y 
(Yaw actuator) and P (pitch actuator) on the primary flight display.

[[Page 31395]]

With the AP switched off, cautions ``YAW SAS'' and ``BACKUP SAS'' 
appeared on the caution and advisory display. When the AP was switched 
on again, the ``YAW SAS'' caution stopped appearing while ``BACKUP 
SAS'' still appeared, EASA reports.
    According to EASA, an investigation indicates that a short circuit 
on the yaw Smart Electro-Mechanical Actuator (SEMA) ``ACTIV'' input to 
ground led to the seizure of all five SEMA units. EASA advises that 
this condition, if not corrected, ``combined with an inoperative 
Autotrim in Pitch or Roll, or combined with an inoperative Autotrim in 
Cyclic and Yaw axis,'' could significantly reduce the pilot's reaction 
time to stabilize the helicopter, resulting in possible loss of 
helicopter control. EASA reports that this situation could occur when 
operating under IFR or night VFR.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs.

Related Service Information

    Eurocopter has issued Alert Service Bulletin MBB-BK117 C-2-22A-013, 
dated October 12, 2012 (ASB), which states that the autopilot and 
caution indication systems failed during flight. Eurocopter's initial 
analysis revealed that a short circuit occurred within a SEMA, causing 
the SEMAs' adjustment travel to ``freeze.'' If this failure is combined 
with a failure of the autotrim system in the pitch, roll, or yaw axis, 
it could reduce the pilot's reaction time to stabilize the helicopter 
``in an unacceptable way.'' The ASB requires revision of sections of 
the master minimum equipment list (MMEL) with respect to inoperative 
TRIM-function to restrict dispatch conditions.

AD Requirements

    Within 25 hours time-in-service (TIS) or 30 days, whichever comes 
first, this AD requires you to insert a statement into the operating 
limitations section of the MBB-BK 117C-2 Rotorcraft Flight Manual under 
paragraph 2.2, Kinds of Operations, prohibiting operation under IFR or 
Night VFR with the autotrim inoperative in pitch or roll, or combined 
inoperative autotrim in cyclic and yaw axis.

Differences Between This AD and the EASA AD

    The EASA AD requires revising the operator's minimum equipment list 
(MEL). We make no requirement regarding the MEL.

Costs of Compliance

    We estimate that this AD will affect 109 helicopters of U.S. 
Registry and that labor costs will average $85 a work hour. Based on 
these assumptions, we expect the following costs:
    Placing the AD in the limitations section of the RFM will require a 
0.2 work-hour and no parts for a cost of $17 per helicopter, $1,853 for 
the U.S. fleet.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we find that 
the risk to the flying public justifies waiving notice and comment 
prior to the adoption of this rule, because the required corrective 
actions must be accomplished within 25 hours TIS or 30 days. As the ECD 
Model MBB-BK 117 C-2 helicopter is used in such areas as emergency 
medical service, newsgathering, and law enforcement, this is a short 
time period.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impractical and contrary to 
the public interest and that good cause exists for making this 
amendment effective in less than 30 days.

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, 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 to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
