**[Docket No. FAA–2015–1744; Directorate Identifier 2015–CE–016–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; British Aerospace Regional Aircraft Airplanes** 

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

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the in-service special detailed inspection technique required for the Jetstream 3200’s life extension program was delayed; consequently, the in-service special detailed inspection technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

**DATES :**  We must receive comments on this proposed AD by July 10, 2015.

**ADDRESSES :**  You may send comments by any of the following methods:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015– 0063, dated April 22, 2015 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

The Jetstream 3200 Life Extension Programme (LEP) permits the airframe life limit to be extended from 45,000 flight cycles (FC) to 67,000 FC. Entry into the LEP requires operators to accomplish inspections specified in the Jetstream 3200 Supplemental Structural Inspections Document (SSID). SSID task 57–10–227 is the inspection requirement for the wing main spar at Rib 36. The threshold for task 57–10–227 is 48,000 FC, with a repeat interval of 16,800 FC, using a Special Detailed Inspection (SDI). Development of the in-service SDI technique required for SSID task 57–10–227 was delayed by BAE Systems (Operations) Ltd, as a result of which it is not formally part of the LEP and may therefore not be accomplished as intended.

This condition, if not corrected, could lead to cracks in the wing main spar remaining undetected, possibly resulting in failure of the wing and loss of the aeroplane.

To address this potential unsafe condition, BAE Systems (Operations) Ltd issued SB 57– JA140140 to provide SDI instructions for the wing main spar at Rib 36, which includes a reduced repeat inspection interval.

For the reasons described above, this AD requires repetitive inspections of the wing main spar around Rib 36 to detect cracks and, depending on findings, accomplishment of the applicable corrective action(s).

The SSID will be revised in due course to include the SDI.

### 29989 Federal Register / Vol. 80, No. 100 / Tuesday, May 26, 2015 / Proposed Rules

Series 3100 & 3200 Service Bulletin 57– JA140140, Original Issue, dated: June 26, 2014. The British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57–JA140140, Original Issue, dated: June 26, 2014, describes procedures for inspections of the wing main spar around Rib 36 to detect cracks and, depending on findings, accomplishment of the applicable corrective action(s). This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** section of this NPRM. FAA’s Determination and Requirements of the Proposed AD

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 proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance

We estimate that this proposed AD will affect 22 products of U.S. registry. We also estimate that it would take about 96 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $179,520, or $8,160 per product.

We have no way of determining any necessary follow-on actions, costs, or the number of products that may need these actions. 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 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

(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. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new AD:
British Aerospace Regional Aircraft: Docket No. FAA–2015–1744; Directorate Identifier 2015–CE–016–AD.

(a) Comments Due Date

We must receive comments by July 10,
2015.
(b) Affected ADs

None. (c) Applicability

This AD applies to British Aerospace Regional Aircraft Jetstream Model 3201 airplanes, all serial numbers, that are:

(1) Certificated in any category; and (2) Modified in service following BAE Systems (Operations) Ltd Service Bulletin (SB) 05–JM8229.
(d) Subject

Air Transport Association of America (ATA) Code 57: Wings.

(e) Reason

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAIdescribes the unsafe condition as the inservice special detailed inspection technique required for the Jetstream 3200’s life extension program was delayed; consequently, the in-service special detailed inspection (SDI) technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this proposed AD to detect and correct cracking in the wing main spar, which could result in structural failure of the wing with consequent loss of control.
(f) Actions and Compliance

Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD:

(1) Before accumulating a total of 53,950 flight cycles (FC) on the airplane or within the next 50 FC after the effective date of this AD, whichever occurs later, and repetitively thereafter at intervals not to exceed 14,300 FC, accomplish an eddy current (EC) and an x-ray inspection of the wing main spar around rib 36 following the instructions of British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57–JA140140, Original Issue, dated June 26, 2014. For the purposes of this AD, owner/operators who do not track total FC, multiply the total number of airplane hours time-in-service (TIS) by 0.75 to calculate the cycles.


### 29990 Federal Register / Vol. 80, No. 100 / Tuesday, May 26, 2015 / Proposed Rules

**Reliability Standard for Transmission System Planned Performance for**  **Geomagnetic Disturbance Events**

**AGENCY :**  Federal Energy Regulatory Commission, Energy.

**ACTION :**  Notice of proposed rulemaking.

**SUMMARY :**  The Federal Energy Regulatory Commission (Commission) proposes to approve Reliability Standard TPL–007–1 (Transmission System Planned Performance for Geomagnetic Disturbance Events). Proposed Reliability Standard TPL– 007–1 establishes requirements for certain entities to assess the vulnerability of their transmission systems to geomagnetic disturbance events (GMDs), which occur when the sun ejects charged particles that interact and cause changes in the earth’s magnetic fields. Entities that do not meet certain performance requirements, based on the results of their vulnerability assessments, must develop a plan to achieve the requirements. The North American Electric ReliabilityCorporation (NERC), the Commissioncertified Electric Reliability Organization, submitted the proposed Reliability Standard for Commission approval in response to a Commission directive in Order No. 779. In addition, the Commission proposes to direct that NERC develop modifications to the benchmark GMD event definition set forth in Attachment 1 of the proposed Reliability Standard so that the definition is not based solely on spatially-averaged data. The Commission also proposes to direct NERC to submit a work plan, and subsequently one or more informationalfilings, that address specific GMDrelated research areas.
