Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Proposed Rules 11723 

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 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 a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

(d) Reason 

This AD was prompted by an uncontained 

multiple turbine blade failure on an RR 

RB211 Trent 772B turbofan engine. We are 

issuing this AD to prevent failure of the 

intermediate pressure turbine disc drive arm 

or burst of the high pressure turbine disk, 

which could lead to uncontained engine 

failure and damage to the airplane. 

(e) Actions and Compliance 

After the effective date of this AD, at the 

next engine shop visit or by December 31, 

2018, whichever occurs first, modify the 

engine by removing any electronic engine 

control (EEC) that incorporates EEC software 

standard A14 or earlier and installing an EEC 

eligible for installation. 

(f) Installation Prohibition 

After modification of an engine as required 

by paragraph (e) of this AD, do not install an 

EEC with software standard A14 or earlier 

into that engine. 

(g) Definition 

(1) For the purposes of this AD, an ‘‘engine 

shop visit’’ is the induction of an engine into 

the shop for maintenance involving the 

separation of pairs of major mating engine 

flanges, except that the separation of engine 

flanges solely for the purposes of 

transportation without subsequent engine 

maintenance does not constitute an engine 

shop visit. 

(2) For the purposes of this AD, an EEC 

‘‘eligible for installation’’ in paragraph (e) of 

this AD is any EEC that does not contain 

software standard A14 or earlier. 

(h) Credit for Previous Actions 

If before the effective date of this AD you 

removed from an engine any EEC that had 

EEC software standard A14 or earlier and 

your engine no longer has an EEC with 

software standard A14 or earlier, you have 

met the requirements of this AD.

Discussion 

The Civil Aviation Authority (CAA), 

which is the aviation authority for New 

Zealand, has issued AD DCA/R2000/42, 

dated January 29, 2014 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for Alpha Aviation Concept 

Limited Model R2160 airplanes. The 

MCAI states: 

The AD is prompted by an overseas 

DR300/180R aircraft accident which occurred 

during take-off. Investigation revealed a 

distorted metal screen shield which 

grounded the ignition switch terminals and 

resulted in loss of engine power. 

Robin aircraft manufactured prior to 1985 

were fitted with ignition switches protected 

with a metal screen shield. With subsequent 

radio and electrical system improvements 

ignition switch shielding is no longer 

required, and most aircraft do not have metal 

screen shielded ignition switches. 

This AD requires a one-time inspection of 

the ignition switch to determine if a metal 

screen shield is installed, and depending on 

findings, to modify or replace the ignition 

switch with a serviceable part. The AD 

prohibits the installation of a metal screen 

shield ignition switch on any aircraft. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2014–0130. 

Relevant Service Information 

Alpha Aviation has issued Service 

Bulletin AA–SB–24–002, Revision 0, 

dated January 2014. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in 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 3 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 $2,550, or $255 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 3 work-hours and require parts 

costing $100, for a cost of $355 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 proposed 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for The 

Boeing Company Model airplanes 

equipped with Rolls-Royce Trent 800 

series engines. This proposed AD was 

prompted by reports of in-flight 

separation of the aft plug from the 

forward plug, which are the two parts of 

the turbine exhaust plug assembly. This 

proposed AD would require installation 

of a serviceable turbine exhaust plug 

assembly (for certain airplanes), and a 

general visual inspection (for certain 

airplanes) to determine the diameter of 

the bolt used at the forward and aft plug 

interface, and applicable corrective 

actions. We are proposing this AD to 

prevent separation of the forward plug 

from the aft plug of the turbine exhaust 

plug assembly, which could result in 

parts departing the airplane and hitting 

the empennage or hitting a person on 

the ground, and destabilizing the 

airplane during a critical flight phase; 

parts remaining on a runway could 

cause damage to another airplane. 

DATES: We must receive comments on 

this proposed AD by April 17, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR
