ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2009–18– 

18 for certain ATR—GIE Avions de 

Transport Re ́gional Model ATR42 and 

ATR72 airplanes. AD 2009–18–18 

required repetitive inspections for 

damage and absence of repair of the 

cockpit forward side windows, and 

replacement if necessary. This new AD 

requires repetitive detailed inspections 

of the cockpit forward side window for 

damage and discrepancies; and 

replacement if necessary. Replacing 

both cockpit forward side windows with 

approved windows terminates the 

repetitive detailed inspections. This 

new AD also expands the applicability 

of AD 2009–18–18. The actions required 

by AD 2009–18–18 are not required by 

this AD. This AD was prompted by 

reports of a cockpit forward right-hand 

side blow out during flight. We are 

issuing this AD to detect and correct air/ 

water leakage of the cockpit forward 

side window, which could lead to rapid 

cabin decompression, resulting in loss 

of control of the airplane. 

DATES: This AD becomes effective May 

8, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 8, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2009–18–18, 

Amendment 39–16014 (74 FR 46336, 

September 9, 2009). AD 2009–18–18 

applied to certain ATR—GIE Avions de 

Transport Re ́gional Model ATR42 and 

ATR72 airplanes. The NPRM published 

in the Federal Register on November 27, 

2013 (78 FR 70892). The NPRM was 

prompted by reports of a cockpit 

forward right-hand side blow out during 

flight. The NPRM proposed to require 

repetitive detailed inspections of the 

cockpit forward side window for 

damage and discrepancies; and 

replacement if necessary. Replacing 

both cockpit forward side windows with 

approved windows would terminate the 

repetitive detailed inspections. The 

NPRM also proposed to expand the 

applicability of AD 2009–18–18. The 

actions required by AD 2009–18–18 are 

not required by the NPRM. We are 

issuing this AD to detect and correct air/ 

water leakage of the cockpit forward 

side window, which could lead to rapid 

cabin decompression, resulting in loss 

of control of 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 2013–0087, 

dated April 9, 2013 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all ATR—GIE Avions de Transport 

Re ́gional Model ATR42–200, –300, 

–320, and –500 airplanes; and Model 

ATR72–101, –201, –102, –202, –211, 

–212, and –212A airplanes; all 

manufacturer serial numbers. The MCAI 

states: 

In 2009, a Left-Hand (LH) forward side 

glass window of an ATR 72–212 aeroplane 

blew out while performing a ground pressure 

test. The investigation results revealed some 

anomalies on the forward side window at the 

level of the z-bar on the windows external 

side and at the level of the inner retainer on 

the windows internal side. Such anomalies 

are considered as precursors of this kind of 

failure. Air or water leakages between the zbar and the outer glass ply, or between the 

inner retainer and inner glass ply indicate the 

presence of deteriorating structural 

components in the window. 

Neither ATR nor PPG Aerospace have 

authorized repairs on the window z-bar or zbar sealant. Any attempted repairs on these 

forward side window z-bars and/or z-bar 

sealants could lead to a similar event as 

described above. 

In-flight loss of a forward side window 

would cause rapid cabin decompression, 

possibly resulting in flight crew 

incapacitation and consequent reduced 

control, or loss of control of the aeroplane, 

and cause the risk of injury to persons on the 

ground. The loss of a forward side window 

while the aeroplane is on the ground, due to 

differential cabin pressure, could result in 

injury to aeroplane occupants or to persons 

outside the aeroplane. 

To address this potential unsafe condition, 

EASA issued AD 2009–0159–E [dated July 

20, 2009] (http://ad.easa.europa.eu/blob/

easa_ad_2009_0159E_superseded.pdf/EAD_

2009-0159-E_1) [which corresponds to FAA 

AD 2009–18–18, Amendment 39–116014 (74 

FR 46336, September 9, 2009)] to require 

repetitive inspections of the affected LH and 

right-hand (RH) cockpit forward side glass 

windows and, in case discrepancies are 

found as defined in PPG Aerospace Service 

Bulletin (SB) NP–158862–001, the 

replacement of the window(s). 

Since that [EASA] AD was issued, a 

cockpit forward RH-side window blew out 

during flight on an ATR72–212 aeroplane. 

Degradation of the window is considered to 

have been the cause for this failure. 

* * * [T]his [EASA] AD * * * requires to 

accomplish the [detailed] inspections in 

accordance with the instructions of Revision 

1 of PPG Aerospace SB NP–158862–001, 

which provides more information on 

examples of [damaged and] discrepant 

conditions. 

This [EASA] AD also requires the removal 

from service of the affected Part Number (P/ 

N) NP158862–1 and P/N NP158862–2 

cockpit forward side windows, which 

constitutes terminating action for the 

repetitive inspections required by this AD.

18620 Federal Register / Vol. 79, No. 64 / Thursday, April 3, 2014 / Rules and Regulations 

The corrective action is replacing 

windows, if damage and discrepancies 

are found. Damage and discrepancies to 

detect during the inspection include zbar existing sealant repair, z-bar 

deformation, separation or gap in the 

sealant bond between the retainer and 

inner glass ply, z-bar deformation and 

retainer gap at same location, or z-bar 

deformation and retainer gap in window 

corner. You may examine the MCAI in 

the AD docket on the Internet at

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 70892, November 27, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available 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 

70892, November 27, 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 70892, 

November 27, 2013). 

Costs of Compliance 

We estimate that this AD affects 43 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Detailed Inspection ................. 1 work-hour × $85 per hour = 

$85 per inspection cycle.

$0 $85 per inspection cycle ........ $3,655 per inspection cycle. 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need this replacement. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 4 work-hours × $85 per hour = $340 ........................... $18,546 $18,886 

Where the service information lists 

required parts costs that are covered 

under warranty, we have assumed that 

there will be no charge for these costs. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2010–23– 

12 for certain Airbus Model A330 and 

Model A340 series airplanes. AD 2010– 

23–12 required inspecting to determine 

the part number for Thales Avionics 

Angle of Attack (AoA) probes, and 

replacing any affected probe with a 

serviceable probe. This new AD adds 

airplanes to the applicability and, for 

certain airplanes, requires that those 

affected probes be replaced. This AD 

was prompted by reports that the AoA 

sensors on certain airplanes were 

modified and re-identified without 

performing the inspection to determine 

the part number; therefore, the affected 

probes were not replaced with 

serviceable probes. We are issuing this 

AD to prevent erroneous AoA 

information and consequent delayed 

activation or non-activation of the AoA 

protection systems, which, in 

combination with flight at a high angle 

of attack, could result in reduced 

controllability of the airplane. 

DATES: This AD becomes effective May 

8, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of May 8, 2014.
