ACTION: Final Rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42 and Model 

ATR72 airplanes. This AD was 

prompted by reports of defective sealing 

between the nacelle lower fairing and 

the underwing box. This AD requires a 

one-time general visual inspection for 

damaged (worn, torn, or abraded) or 

missing seals between the nacelle lower 

fairing and the underwing box of both 

the left-hand and right-hand engine 

nacelles, and replacement of the seal 

and/or shims if necessary. We are 

issuing this AD to prevent the decrease 

of the fire extinguishing agent 

efficiency, which could delay fire 

extinction and allow fire propagation 

out of the nacelle fire protected area, 

resulting in damage to the airplane. 

DATES: This AD becomes effective 

March 26, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 26, 2014.

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 certain ATR—GIE Avions de 

Transport Re ́gional Model ATR42 and 

Model ATR72 airplanes. The NPRM 

published in the Federal Register on 

September 25, 2013 (78 FR 58967). The 

NPRM was prompted by reports of 

defective sealing between the nacelle 

lower fairing and the underwing box. 

The NPRM proposed to require a onetime general visual inspection for 

damaged (worn, torn, or abraded) or 

missing seals between the nacelle lower 

fairing and the underwing box of both 

the left-hand and right-hand engine 

nacelles, and replacement of the seal 

and/or shims if necessary. We are 

issuing this AD to prevent the decrease 

of the fire extinguishing agent 

efficiency, which could delay fire 

extinction and allow fire propagation 

out of the nacelle fire protected area, 

resulting in damage to the airplane. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0160, 

dated August 24, 2012 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Some cases of defective sealing have been 

reported on in-service aeroplanes on LeftHand (LH) and Right-Hand (RH), between the 

nacelle lower fairing and the underwing box. 

Investigation results have shown that this 

issue was due to either damaged or missing 

seal and/or incorrect adjustment of the 

nacelle lower fairing. 

This condition, if not detected and 

corrected, may decrease the extinguishing 

agent efficiency, delay the fire extinction and 

allow fire propagation out of the nacelle fire 

protected area, possibly resulting in damage 

to the aeroplane. 

For the reasons described above, this 

[EASA] AD requires a one-time [general 

visual] inspection of the affected area 

[between the nacelle lower fairing and the 

underbox wing for damaged (worn, torn, or 

abraded) or missing seals] and, depending on 

findings, accomplishment of applicable 

corrective actions to restore the area integrity.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 58967, September 25, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

58967, September 25, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 58967, 

September 25, 2013). 

Costs of Compliance 

We estimate that this AD affects 42 

airplanes of U.S. registry. 

We also estimate that it will take 

about 4 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts will cost 

about $0 per product. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $14,280, or $340 

per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 36-work-hours and require parts 

costing $341, for a cost of $3,401 per 

product. We have no way of 

determining the number of aircraft that 

might need this action. 

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 AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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 that this AD: 

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.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–1A11 

(CL–600), CL–600–2A12 (CL–601), and 

CL–600–2B16 (CL–601–3A, CL–601–3R, 

and CL–604 Variants) airplanes. This 

AD requires repetitive inspections for 

fractured or incorrectly oriented 

fasteners on the inboard flap hinge-box 

forward fittings on both wings, and 

fastener replacement if necessary. This 

AD was prompted by two reports of 

fractured fastener heads found on the 

inboard flap hinge-box forward fitting. 

We are issuing this AD to detect and 

correct incorrectly oriented or fractured 

fasteners, which could result in 

detachment of the flap hinge-box and 

the flap surface, and consequent 

reduced controllability of the airplane. 

DATES: This AD becomes effective 

March 6, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 6, 2014 

We must receive comments on this 

AD by April 7, 2014.
