Discussion

The Federal Office of Civil Aviation (FOCA), which is the aviation authority for Switzerland, has issued AD HB– 2014–001, dated July 25, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for PILATUS Aircraft Ltd. Model PC–7 airplanes and was based on mandatory continuing airworthiness information originated by an aviation authority of another country. The MCAI states:

This Airworthiness Directive (AD) is prompted due to the possibility of cracks in


## 60390 Federal Register / Vol. 79, No. 194 / Tuesday, October 7, 2014 / Proposed Rules

some critical parts. It is possible that stress corrosion cracks may occur on various parts of the aircraft structure initially made of aluminium alloy AA2024–T351 which is susceptible to Stress Corrosion Cracking (SCC). Later in production, the material specification was changed to aluminium alloy AA2124–T851 to decrease the risk of stress corrosion. The Part Number (P/N) of the affected structural parts are not always changed when the new material was introduced.

Such a condition, if left uncorrected, could lead to failure of critical parts on the aircraft structure and will prejudice the structural integrity of the aircraft.

In order to correct and control the situation, this AD requires a one-time check to identify the material specification and inspect the affected areas of the airframe that are made of aluminium alloy AA2024–T351. Any structural parts of the aircraft structure found to be cracked must be reported to Pilatus prior to further flight.



### The MCAI also requires replacement of the elevator center control-rod, P/N 116.35.07.271 or 116.35.07.345; and shackle, P/N 116.35.07.183. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–
0770.

Relevant Service Information

PILATUS Aircraft Ltd. has issued PILATUS PC–7 Service Bulletin No: 51– 001, Revision No. 1, dated August 26, 2014. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. PILATUS PC–7 Service Bulletin No: 51–001 was revised to Revision No. 1 after the issuance of the MCAI. 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 10 products of U.S. registry. We also estimate that it would take about 30 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $4,700 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $72,500, or $7,250 per product.

In addition, we estimate that any necessary follow-on actions would take about 14 work-hours and require parts costing $10,000, for a cost of $11,190 per product. We have no way of determining the number of products that may need these actions.
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:

PILATUS Aircraft Ltd.: Docket No. FAA– 2014–0770; Directorate Identifier 2014– CE–024–AD.
(a) Comments Due Date

We must receive comments by November 21, 2014.
(b) Affected ADs

None. (c) Applicability

This AD applies to PILATUS Aircraft Ltd. Model PC–7 airplanes, manufacturer serial numbers (MSN) 101 through MSN 618, certificated in any category.
(d) Subject

Air Transport Association of America (ATA) Code 51: Standard Practices/ Structures.
(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 MCAI describes the unsafe condition as possible cracking from stress corrosion on various parts of the aircraft structure made of aluminum alloy AA2024–T351. We are issuing this proposed AD to detect and correct stress corrosion cracks that may occur on various parts of the airplane structure initially made of aluminum alloy AA2024– T351, which is susceptible to stress corrosion cracking (SCC). Such a condition, if left uncorrected, could lead to failure of critical parts on the airplane structure and weaken the structural integrity of the aircraft.
(f) Actions and Compliance

Unless already done, within the next 12 months after the effective date of this AD, perform a one-time conductivity test of items 6 through 9 and 11 through 13 as listed in paragraph 1.A.(2) of PILATUS PC–7 Service Bulletin No: 51–001, Revision No. 1, dated August 26, 2014, to check the material of the parts—determine whether they are made of aluminum alloy AA2124–T851 or aluminum alloy AA2024–T351. Do not install any item


## 60391 Federal Register / Vol. 79, No. 194 / Tuesday, October 7, 2014 / Proposed Rules

unless it has been inspected following the applicable paragraph of PILATUS PC–7 Service Bulletin No: 51–001, Revision No. 1, dated August 26, 2014.

**AGENCY**

### : Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), Department of Justice.

**ACTION** 

### : Notice of proposed rulemaking.

**SUMMARY**

### : The Department of Justice proposes to codify the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) procedures and practices in connection with the disapproval of initial applications, denials of renewal, and revocations of explosives licenses or permits. The proposed regulations will be codified in a new part entitled ‘‘Rules and Practice in License and Permit Proceedings.’’ The proposed regulations are based upon the regulations that ATF relied upon prior to its transfer from the Department of the Treasury to the Department of Justice.

Additionally, the Department proposes minor revisions to regulations governing administrative proceedings related to the denial, suspension, or revocation of a license, and the imposition of a civil fine under Federal firearms law to reference regulations under ATF authority. These proposed revisions remove all references to statutes, regulations, positions, and other terms that are applicable only to the Department of the Treasury. These
