ACTION: Final rule. sroberts on DSK5SPTVN1PROD with RULES AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of certain sliding windows that were difficult to operate after landing. This AD requires a detailed inspection to identify part numbers of sliding windows and sliding window seals, and modification if necessary. This AD also includes an optional replacement. We are issuing this AD to detect and correct incorrect seals, which could lead to the functional loss of the sliding window as an exit, possibly preventing the flightcrew from safely evacuating the airplane during an emergency. DATES: This AD becomes effective February 10, 2014. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 10, 2014.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM published in the Federal Register on July 3, 2013 (78 FR 40057). The NPRM proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0011, dated January 15, 2013 (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: Several occurrences have been reported on A320 family aeroplanes of PPG sliding windows that were difficult to operate after landing. The investigation results revealed that when a seal having Part Number (P/N) 22– 17–7640–1 or P/N 22–17–7640–2 is installed on a sliding window, closure of the window can create a vacuum between the 2 tubes of the pressure seal, leading to the window remaining stuck to the frame on the fuselage side, due to suction effect. This condition, if not detected and corrected, could lead to the functional loss of the sliding window as an exit, possibly preventing the flight crew from safely evacuating the aeroplane during an emergency. For the reasons described above, this [EASA] AD requires a one-time detailed inspection (DI) of the sliding windows and its seal to identify the affected sliding window seals and, depending on findings, accomplishment of the applicable corrective actions [corrective action includes a modification or replacement]. The subject area on certain Airbus Model A318, A319, and A321 series airplanes is almost identical to that on the affected Model A320 series airplanes. Therefore, those Model A318, A319, and A321 series airplanes may be subject to the unsafe condition revealed on the Model A320 series airplanes. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/ PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 543 #!documentDetail;D=FAA-2013-04670002. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Request for Identification Change United Airlines (UAL) requested that the modification be recorded at the part number level, instead of the serial number level. UAL explained that reidentifying the post-modification window at the serial number level only will potentially lead to de-modification of the window, which could result in the unsafe condition identified in the NPRM (78 FR 40057, July 3, 2013). UAL reasoned that re-identifying the window at the part number level would better allow operators to manage the post-AD configuration. UAL provided further substantiation to add the ‘‘M’’ to the part number instead of the serial number during a teleconference with us during the week of September 23, 2013. UAL’s reason for adding the ‘‘M’’ to the part number is related to the convenience/preference of UAL maintenance practices. We disagree with the request to require recording the modification at the part number level. After coordinating with Airbus, we have determined that adding ‘‘M’’ to the serial number will prevent installation of unsafe sliding window part numbers without changing the part number configuration and associated administrative processes to change part numbers. However, we have revised paragraph (h) of this final rule to include phrasing to clarify and to allow for modification to be recorded at the serial number level of the affected part number. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 40057, July 3, 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 40057, July 3, 2013). Costs of Compliance Based on the service information, we estimate that this AD affects about 851 products of U.S. registry. We also estimate that it will take about 3 work- E:\FR\FM\06JAR1.SGM 06JAR1 544 Federal Register / Vol. 79, No. 3 / Monday, January 6, 2014 / Rules and Regulations hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $217,005, or $255 per product. In addition, we estimate that any necessary follow-on actions will take about 1 work-hour and require parts costing $0, for a cost of $85 per product. We have no way of determining the number of products that may need these actions. sroberts on DSK5SPTVN1PROD with RULES 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.

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A318, A319, A320, and A321 series airplanes. This AD was
prompted by reports of certain sliding windows that were difficult to
operate after landing. This AD requires a detailed inspection to
identify part numbers of sliding windows and sliding window seals, and
modification if necessary. This AD also includes an optional
replacement. We are issuing this AD to detect and correct incorrect
seals, which could lead to the functional loss of the sliding window as
an exit, possibly preventing the flightcrew from safely evacuating the
airplane during an emergency.

DATES: This AD becomes effective February 10, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
The NPRM published in the Federal Register on July 3, 2013 (78 FR
40057). The NPRM proposed to correct an unsafe condition for the
specified products.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2013-0011, dated January 15, 2013 (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:

Several occurrences have been reported on A320 family aeroplanes
of PPG sliding windows that were difficult to operate after landing.
The investigation results revealed that when a seal having Part
Number (P/N) 22-17-7640-1 or P/N 22-17-7640-2 is installed on a
sliding window, closure of the window can create a vacuum between
the 2 tubes of the pressure seal, leading to the window remaining
stuck to the frame on the fuselage side, due to suction effect.
This condition, if not detected and corrected, could lead to the
functional loss of the sliding window as an exit, possibly
preventing the flight crew from safely evacuating the aeroplane
during an emergency.
For the reasons described above, this [EASA] AD requires a one-
time detailed inspection (DI) of the sliding windows and its seal to
identify the affected sliding window seals and, depending on
findings, accomplishment of the applicable corrective actions
[corrective action includes a modification or replacement].

The subject area on certain Airbus Model A318, A319, and A321
series airplanes is almost identical to that on the affected Model A320
series airplanes. Therefore, those Model A318, A319, and A321 series
airplanes may be subject to the unsafe condition revealed on the Model
A320 series airplanes. You may examine the MCAI in the AD docket on the
Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-
0467-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We considered the comment received.

Request for Identification Change

United Airlines (UAL) requested that the modification be recorded
at the part number level, instead of the serial number level. UAL
explained that re-identifying the post-modification window at the
serial number level only will potentially lead to de-modification of
the window, which could result in the unsafe condition identified in
the NPRM (78 FR 40057, July 3, 2013). UAL reasoned that re-identifying
the window at the part number level would better allow operators to
manage the post-AD configuration.
UAL provided further substantiation to add the ``M'' to the part
number instead of the serial number during a teleconference with us
during the week of September 23, 2013. UAL's reason for adding the
``M'' to the part number is related to the convenience/preference of
UAL maintenance practices.
We disagree with the request to require recording the modification
at the part number level. After coordinating with Airbus, we have
determined that adding ``M'' to the serial number will prevent
installation of unsafe sliding window part numbers without changing the
part number configuration and associated administrative processes to
change part numbers. However, we have revised paragraph (h) of this
final rule to include phrasing to clarify and to allow for modification
to be recorded at the serial number level of the affected part number.

Conclusion

We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting
this AD with the change described previously and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 40057, July 3, 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 40057, July 3, 2013).

Costs of Compliance

Based on the service information, we estimate that this AD affects
about 851 products of U.S. registry. We also estimate that it will take
about 3 work-

[[Page 544]]

hours per product to comply with the basic requirements of this AD. The
average labor rate is $85 per work-hour. Based on these figures, we
estimate the cost of this AD on U.S. operators to be $217,005, or $255
per product.
In addition, we estimate that any necessary follow-on actions will
take about 1 work-hour and require parts costing $0, for a cost of $85
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 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0
2. The FAA amends Sec. 39.13 by adding the following new AD:

2013-26-07 Airbus: Amendment 39-17716. Docket No. FAA-2013-0467;
Directorate Identifier 2013-NM-023-AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective February 10,
2014.

(b) Affected ADs

None.

This AD applies to Airbus Model A318-111, -112, -121, and -122
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -
133 airplanes; Model A320-111, -211, -212, -214, -231, -232, and -
233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes; certificated in any category; all
manufacturer serial numbers.

(d) Subject

Air Transport Association (ATA) of America Code 56, Windows.

(e) Reason

This AD was prompted by reports of certain sliding windows that
were difficult to operate after landing. We are issuing this AD to
detect and correct incorrect seals, which could lead to the
functional loss of the sliding window as an exit, possibly
preventing the flightcrew from safely evacuating the airplane during
an emergency.

(f) Compliance

You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.

(g) Inspection

Within 750 flight cycles or 750 flight hours or 4 months after
the effective date of this AD, whichever occurs first: Do a detailed
inspection to identify part numbers (P/Ns) of each window and seal
of the left-hand (LH) and right-hand (RH) sliding windows and
sliding window seals, in accordance with the Accomplishment
Instructions of Airbus Service Bulletin A320-56-1016, including
Appendices 01 and 02, dated September 14, 2012. A review of airplane
maintenance records is acceptable in lieu of this inspection if the
part number of the window and seal of the LH and RH sliding windows
and sliding window seals can be conclusively determined from that
review.

(h) Modification

If a sliding window part number identified in table 1 to
paragraph (h) of this AD is found during the inspection required by
paragraph (g) of this AD; and the serial number of the part does not
have the modification amendment letter ``M,'' and does have sliding
window seals having P/N 22-17-7640-1 or P/N 22-17-7640-2 installed:
Within the compliance time specified in paragraph (g) of this AD,
modify the sliding window seal (which includes adding the letter
``M'' to serial number of the affected part), in accordance with the
Accomplishment Instructions of Airbus Service Bulletin A320-56-1015,
dated September 14, 2012.
