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.


### 31395 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.

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. List of Subjects in 14 CFR Part 39

**Amendment of Class D and Class E Airspace; Portland-Hillsboro, OR** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This action modifies Class E airspace at Portland-Hillsboro Airport, Portland-Hillsboro, OR, to accommodate aircraft departing and arriving under Instrument Flight Rule (IFR) operations at the airport. Also, the geographic coordinates are updated for the airport. This action, initiated by the biennial review of the Portland-Hillsboro airspace area, improves the safety and management of IFR operations at the airport.

**DATES :**  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 :**  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 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 createdsouth 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 modifiescontrolled 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,’’
