**SUPPLEMENTARY INFORMATION :** 

Discussion

On July 25, 2014, we issued Emergency AD 2014–15–51, which requires inspection and replacement as necessary of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint on Embraer S.A. Model EMB–500 airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This action was prompted the Agencia Nacional De Aviacao Civil (ANAC), which is the aviation authority for Brazil, issuing emergency AD No.: 2014–07–02, dated July 25, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for Embraer S.A. Model EMB–500 airplanes. The MCAI states:

This EAD results from a report of crackingin the barrel nuts at the horizontal stabilizerto-vertical stabilizer attachment joint found during an inspection at the assembly line. This EAD is being issued to detect and correct cracking of the barrel nuts at the horizontal stabilizer-to-vertical stabilizer attachment joint, which could result in reduced structural integrity of the affected part and consequent detachment of the horizontal stabilizer from the airplane.

Since this condition may exist in other airplanes of the same type and affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this EAD in the indicated time limit without prior notice. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–0511.

Relevant Service Information

Embraer S.A. has issued Phenom Alert Service Bulletin No. 500–55– A004, Revision 02, dated July 25, 2014. The actions described in this service bulletin are intended to correct the unsafe condition identified in the MCAI.

FAA’s Determination

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
AD Requirements

This AD requires an inspection and replacement as necessary of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint. This AD also requires sending the inspection results to Embraer.

FAA’s Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of a report of cracking in the barrel nuts at the horizontal stabilizer-to-vertical stabilizer attachment joint found during an inspection at the assembly line. This condition could result in reduced structural integrity of the affected part and consequent detachment of the horizontal stabilizer from the airplane. Since this condition may exist in other airplanes of the same type and affects flight safety, an immediate corrective action is required. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include the docket number FAA–2014–0511 and Directorate Identifier 2014–CE–023–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance

We estimate that this AD will affect 45 products of U.S. registry. We also estimate that it would take about 2.5 work-hours 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 the AD on U.S. operators to be $9,562.50 or $212.50 per product.

In addition, we estimate that any necessary follow-on actions would take about 2 work-hours and require parts costing $150, for a cost of $320 per product. We have no way of determining the number of products that may need these actions.

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. Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES–200. 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

**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 Airbus Model A330–200 Freighter, A330–200, A330–300, and A340–200, A340–300, A340–500, and A340–600 series airplanes. The NPRM published in the Federal Register on May 15, 2014 (79 FR 27814).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0201, dated September 4, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information to correct an unsafe condition on all Airbus Model A330–200 Freighter, A330–200, A330– 300, and A340–200, –300, –500, and –600 series airplanes. The MCAI states:

Investigation results on the Cabin Pressure Control System (CPCS) safety valve demonstrate that this part is subject to repetitive restoration every 50,000 flight hours (FH) or 12 years, but this airworthiness instruction is not yet reflected in the instructions for continuing airworthiness. Moreover, this safety valve, part of the CPCS, is not failure monitored.

In order to maintain the required safety objectives, the CPCS safety valves must be replaced by a serviceable part no later than the above values.

For the reasons describe above, this [EASA] AD requires repetitive replacement of CPCS safety valves.

Exceeding the service life limits of the CPCS safety valve, in the event of a failure, could result in excessive positive or negative differential pressure in the fuselage, and consequent incapacitation or injuries to airplane occupants.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0251-
0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 27814, May 15, 2014) or on the determination of the cost to the public. ‘‘Contacting the Manufacturer’’ Paragraph in This AD

Since late 2006, we have included a standard paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD.

The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair.
