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 


asabaliauskas on DSK5VPTVN1PROD with RULES
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.

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

Homeland Security Act of 2002 

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
