Discussion

On January 23, 2012, we issued AD 2012–02–13, Amendment 39–16936 (77 FR 5994, February 7, 2012), which required repetitively inspecting the right-hand side of the junction frame for a crack, and if there was a crack, replacing the tailboom before further flight.

AD 2012–02–13 was prompted by AD No. 2011–0116, dated July 6, 2011 (AD 2011–0116), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Eurocopter France (now Airbus Helicopters) Model EC130B4 helicopters. EASA advises of several reports of cracks in the junction frame developing in the plane of the rivet head countersink on the right-hand side of the Fenestron and spreading to the web of the frame. EASA further advises that this condition could lead to structural failure resulting in Fenestron detachment and subsequent loss of control of the helicopter. EASA AD 2011–0116 required compliance with Eurocopter’s service information to repetitively inspect the affected area and depending on findings, accomplish corrective actions.

Actions Since AD 2012–02–13 Was Issued

Since we issued AD 2012–02–13, EASA has issued AD No. 2014–0114–E, dated May 8, 2014, which superseded EASA AD 2011–0116, for Airbus Helicopters Model EC130B4 helicopters, except those with Modification (MOD) 073880, those with MOD 074609, or those that have been repaired in accordance with certain Repair Design Approval Sheets. EASA advises that after issuing EASA AD 2011–0116, Airbus Helicopters developed MOD 074609, which limits the risk of cracks appearing on the junction frame, and revised its service information to expand the area of inspection. EASA AD 2014–0114–E requires repetitively inspecting the entire circumference of the junction frame for a crack, and also requires altering the helicopter in accordance with MOD 074609 as a terminating action for the repetitive inspections.

We have also determined that the repetitive inspection interval can be reduced to 40 hours time-in-service (TIS) as specified in the Airbus Helicopters service information.

FAA’s Determination

These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, 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

Airbus Helicopters, Inc. has published Emergency Alert Service Bulletin (EASB) No. 53A019, Revision 1, dated April 15, 2014 (EASB 53A019). EASB 53A019 describes procedures for inspecting the entire circumference of the junction frame from the inside and outside for cracks. If there is a crack, EASB 53A019 requires contacting Airbus Helicopters for approved repair instructions. Finally, if there is not a crack, EASB 53A019 requires altering the helicopter in accordance with MOD 074609 before December 12, 2017.
AD Requirements

This AD requires repetitively inspecting the circumference of the junction frame for a crack by complying with specified portions of the manufacturer’s service bulletin, and replacing the junction frame if there is a crack. This AD also prohibits installing a tailboom without MOD 073880 on any helicopter. Differences Between This AD and the EASA AD

The EASA AD allows for flights for a certain period of time with known cracks, while this AD does not permit operations with known cracks. The EASA AD allows for an initial inspection which does not require stripping the paint, and then stripping the paint prior to inspection within 110 flight hours. This AD mandates stripping the paint as part of the initial inspection. The EASA AD requires altering the helicopter with MOD 074609 before December 31, 2017, and this AD does not. The EASA AD requires contacting Airbus Helicopters for repair instructions if there is a crack, while this AD requires replacing the junction frame. Costs of Compliance

We estimate that this AD affects 160 helicopters of U.S. Registry.

We estimate that operators may incur the following costs in order to comply with this AD. Inspecting the junctionframe for a crack will require 1 workhour at an average labor cost of $85 per hour, for a total cost per inspection cycle $85 per helicopter and $13,600 for the entire fleet. If required, replacing a tailboom will require 50 work-hours and required parts will cost $60,000, for a cost per helicopter of $64,250.
FAA’s Justification and Determination of the Effective Date

Providing an opportunity for public comments before adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the cracks are in a primary structure of the helicopter that may prevent further safe flight and the required corrective actions must be accomplished within 10 hours TIS, a very short time period for the air tour and helicopter emergency medical services operations of these helicopters.

Since an unsafe condition exists that requires the immediate adoption of this AD, we determined notice and opportunity for public comment before issuing this AD are impracticable 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:


### 60336 Federal Register / Vol. 79, No. 194 / Tuesday, October 7, 2014 / Rules and Regulations

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.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to all Pacific Aerospace Limited Model 750XL airplanes. That NPRM was published in the Federal Register on August 1, 2014 (79 FR 44722), and proposed to supersede AD 2014–04–03, Amendment 39–17761 (79 FR 10344, February 25, 2014).

Since we issued AD 2014–04–03, Amendment 39–17761 (79 FR 10344, February 25, 2014), Pacific Aerospace Limited revised the related service information.

The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, has issued AD DCA/ 750XL/15A, dated June 26, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for Pacific Aerospace Limited Model 750XL airplanes. The MCAI states:

DCA/750XL/15A revised to mandate the embodiment of modification PAC/XL/0627 to the control column attachment per the instructions in Pacific Aerospace Limited Service Bulletin (SB) PACSB/XL/070 issue 2, dated 3 June 2014.

The MCAI can be found in the AD docket on the Internet at: http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0516-

0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 44722, August 1, 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 the 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 (79 FR 44722, August 1, 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 44722, August 1, 2014).
Costs of Compliance

We estimate that this AD will affect 17 products of U.S. registry. We alsoestimate that it will take about 6 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $200 per product.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $12,070, or $710 per product.

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

The cost difference between AD 2014–04–03, Amendment 39–17761 (79 FR 10344, February 25, 2014), and this AD is the increase in work-hours from 1.5 to 6 and the increase in cost for parts from $100 to $200, for an overall cost difference on U.S. operators to be $8,202.50, or $482.50 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
