The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2014–0012; Directorate Identifier 2012–NM–007–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2004–16– 01, that applies to certain Airbus Model A330–200 and –300, and Model A340– 200 and –300, series airplanes. AD 2004–16–01 currently requires repetitive inspections for cracking of the chromed area of the left and right piston rods for the main landing gear (MLG) retraction actuators, and related investigative and corrective actions if necessary. Since we issued AD 2004– 16–01, we have determined that the presence of water in the internal volume of the piston rod can consequently lead to propagation of longitudinal cracking in the body of the piston rod. We have also determined through sampling that certain retraction actuator piston rods of the MLG need to be replaced. This proposed AD would require repetitive draining of any fluid from the retraction actuator piston rod internal volume and sealing of the vent hole; repetitive ultrasonic inspections of the upper end of the piston rods, and corrective actions if necessary; a one-time ultrasonic inspection (longitudinal and circumferential) of the full-length of the piston rod, and corrective actions if necessary; and a terminating modification of the left-hand and righthand MLG retraction actuators. We are proposing this AD to prevent cracking of the piston rods for the MLG retraction actuators, which could result in rupture of a piston rod, non-damped extension tkelley on DSK3SPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 16:49 Feb 05, 2014 Jkt 232001 of the MLG, high loads on the fully extended MLG, and consequent reduced structural integrity of the MLG.

Discussion On July 23, 2004, we issued AD 2004– 16–01, Amendment 39–13757 (69 FR 46979, August 4, 2004). AD 2004–16–01 requires actions intended to address an unsafe condition on the products listed above. Since we issued AD 2004–16–01, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2011– 0178R1, dated March 6, 2012, corrected March 7, 2012 (for Model A340–200 and –300 series airplanes); and EASA AD 2011–0179R1, dated March 6, 2012 (for Model A330–200 and –300 series airplanes) (both referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’); to correct an unsafe condition for the specified products. EASA AD 2011–0178R1, dated March 6, 2012, corrected March 7, 2012, states: During an approach phase, the flight crew of an A330 aeroplane had to perform a freefall extension of the left-hand (LH) MLG. Rupture of the LH MLG retraction actuator piston rod was found near the rod attachment point. The inspection revealed at the location of the rupture the presence of corrosion resulting from incorrect application of the anticorrosion protection, and circumferential cracks resulting from normal operational loading effects. Since the above rupture, new cases of crack propagation along the length of the piston rod occurred. These ruptures led to a nondamped extension of the landing gear. Fully E:\FR\FM\06FEP1.SGM 06FEP1 tkelley on DSK3SPTVN1PROD with PROPOSALS Federal Register / Vol. 79, No. 25 / Thursday, February 6, 2014 / Proposed Rules extended, the landing gear assembly was submitted to high loads jeopardizing its structural integrity. This condition, if not detected and corrected, could lead to MLG failure during landing or roll-out and consequent damage to the aeroplane and injury to occupants. DGAC France issued AD F–2005–098 (EASA approval 2005–5887) [and AD F– 2005–099 (EASA approval 2005–5888)] to address this unsafe condition [the FAA issued AD 2004–16–01, Amendment 39– 13757 (69 FR 46979, August 4, 2004)]. Since that [DGAC France] AD was issued, the results of extensive investigation determined that the presence of water in the internal volume of the piston rod can lead to the formation of ice which represents a potential source of high magnitude tensile hoop stresses in the material of the rod, leading to propagation of longitudinal crack in the body of the piston rod. Prompted by these findings, EASA issued AD 2006–0301, partially retaining the requirements of DGAC France AD F–2005– 099, which was superseded, and to revise the inspection requirements as follows: a. Extend the repetitive inspections interval for the removal of fluid from the internal volume of the piston rod using flight cycles in lieu of flight hours as this better represents the mechanism for the accumulation of water within the piston rod. b. Remove the preliminary visual inspection from the ultrasonic longitudinal inspection of the upper end of the piston rod. c. Add a new one-time ultrasonic longitudinal and circumferential inspection of the full piston rod length to eliminate any parts that exhibit severe corrosion along the internal length of the piston rod. d. Require installation of new design hollow piston rod Part Number (P/N) 114256328 (Airbus mod. 52980—SB A340– 32–4222 Revision 01) without a vent hole, thus eliminating moisture ingress as the terminating action. EASA AD 2006–0301 was later revised: —at revision 01, to correct a number of typographical errors and to add reference to Airbus SB A340–32–4212 Revision 04, and —at revision 02 to extend the inspections threshold from 3 to 6 years in service usage for retraction actuator piston rod P/N 114256321 issue 06 which was reidentified to P/N 114256326 issue 01 in accordance with the instructions of Airbus SB A340–32–4260. More recently, the sampling of piston rod P/N 114256326 issue 1 and P/N 114256321 issue 06 have confirmed the need to replace all retraction actuator piston rods with a piston rod P/N114256328. For the reasons described above, this [EASA] AD at original issue retained the requirements of EASA AD 2006–0301R2 (https://ad.easa.europa.eu/blob/easa_ad_ 2006_0301_R2_superseded.pdf/AD_20060301R2_1), which is superseded, and required the replacement of all retraction actuator piston rods with a piston rod P/N 114256328, which constitutes terminating action to the repetitive requirements of this AD. This [EASA] AD is revised to clarify that aeroplanes on which Airbus mod. 52980 has VerDate Mar<15>2010 16:49 Feb 05, 2014 Jkt 232001 been embodied in production are not required to accomplish the reidentification of MLG retraction actuator P/N 114256002–055 which is mentioned in the accomplishment instructions of Airbus SB A340–32–4222 Revision 03. This [EASA] AD has been republished to correct a typographical mistake of the applicable Airbus SB number in the Applicability (in the Note) and in the Reason sections of this [EASA] AD. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0012. Relevant Service Information Airbus has issued the following service bulletins. • Airbus Mandatory Service Bulletin A330–32–3173, Revision 05, dated September 26, 2008. • Airbus Mandatory Service Bulletin A330–32–3180, Revision 03, dated January 28, 2011. • Airbus Mandatory Service Bulletin A340–32–4212, Revision 05, dated September 26, 2008. • Airbus Mandatory Service Bulletin A340–32–4222, Revision 03, dated January 28, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information EASA AD 2011–0178R1, dated March 6, 2012, corrected March 7, 2012 (for Model A340–200 and –300 series airplanes); and AD 2011–0179R1, dated March 6, 2012 (for Model A330–200 and –300 series airplanes); require replacement of the retraction actuator within 10 flight cycles if the findings of the ultrasonic inspection of the retraction actuator piston rod end are between 75% and 90% FSH (full screen height) and between 5 and 7 in time base. However, paragraph (n) of this proposed AD would require PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 7099 replacement of the retraction actuator before further flight if the findings of the ultrasonic inspection of the retraction actuator piston rod end are higher than 75% and between 5 and 7 in time base. EASA AD 2011–0178R1, dated March 6, 2012, corrected March 7, 2012 (for Model A340–200 and –300 series airplanes); and AD 2011–0179R1, dated March 6, 2012 (for Model A330–200 and –300 series airplanes); require replacement of the retraction actuator within 10 landings if the findings of the one-time ultrasonic circumferential inspection of the full-length chromed part of the piston rod give an indication between 75% and 90% FSH and between 7 and 9.5 in time base. However, paragraph (p)(2) of this proposed AD would require replacement of the retraction actuator before further flight if inspection findings are higher than 75% FSH and between 7 and 9.5 in time base. We have determined that, because of the safety implications and consequences associated with those findings, the actuator must be replaced before further flight. These differences have been coordinated with EASA. Costs of Compliance We estimate that this proposed AD affects 24 Model A330–200 and –300 series airplanes of U.S. registry. There are no Model A340–200 and –300 series airplanes of U.S. registry. We estimate that it would take about 67 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 $56,000 per product (2 actuators). Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,480,680, or $61,695 per product. In addition, we estimate that any necessary follow-on actions would take about 38 work-hours and require parts costing $56,000 (2 actuators), for a cost of $59,230 per product. We have no way of determining the number of aircraft that might need these actions. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 E:\FR\FM\06FEP1.SGM 06FEP1 7100 Federal Register / Vol. 79, No. 25 / Thursday, February 6, 2014 / Proposed Rules 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 proposed AD is 2120– 0056. The paperwork cost associated with this proposed 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 proposed 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. tkelley on DSK3SPTVN1PROD with PROPOSALS 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. 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, VerDate Mar<15>2010 17:57 Feb 05, 2014 Jkt 232001 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. 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.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This proposed AD was prompted by reports of corroded, migrated, or broken spring pins of the girt bar floor fitting; in one case the broken pins prevented a door escape slide from deploying during a maintenance test. This proposed AD would require replacing the existing spring pins at each passenger entry door at both girt bar floor fittings with new spring pins. We are proposing this AD to prevent broken or migrated spring pins of the girt bar floor fittings, which could result in improper deployment of the escape slide/raft and consequent delay and injury during evacuation of passengers and crew from the cabin in the event of an emergency.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2004-16-
01, that applies to certain Airbus Model A330-200 and -300, and Model 
A340-200 and -300, series airplanes. AD 2004-16-01 currently requires 
repetitive inspections for cracking of the chromed area of the left and 
right piston rods for the main landing gear (MLG) retraction actuators, 
and related investigative and corrective actions if necessary. Since we 
issued AD 2004-16-01, we have determined that the presence of water in 
the internal volume of the piston rod can consequently lead to 
propagation of longitudinal cracking in the body of the piston rod. We 
have also determined through sampling that certain retraction actuator 
piston rods of the MLG need to be replaced. This proposed AD would 
require repetitive draining of any fluid from the retraction actuator 
piston rod internal volume and sealing of the vent hole; repetitive 
ultrasonic inspections of the upper end of the piston rods, and 
corrective actions if necessary; a one-time ultrasonic inspection 
(longitudinal and circumferential) of the full-length of the piston 
rod, and corrective actions if necessary; and a terminating 
modification of the left-hand and right-hand MLG retraction actuators. 
We are proposing this AD to prevent cracking of the piston rods for the 
MLG retraction actuators, which could result in rupture of a piston 
rod, non-damped extension of the MLG, high loads on the fully extended 
MLG, and consequent reduced structural integrity of the MLG.

DATES: We must receive comments on this proposed AD by March 24, 2014.

Discussion

    On July 23, 2004, we issued AD 2004-16-01, Amendment 39-13757 (69 
FR 46979, August 4, 2004). AD 2004-16-01 requires actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2004-16-01, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA AD 2011-0178R1, dated March 6, 
2012, corrected March 7, 2012 (for Model A340-200 and -300 series 
airplanes); and EASA AD 2011-0179R1, dated March 6, 2012 (for Model 
A330-200 and -300 series airplanes) (both referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''); to 
correct an unsafe condition for the specified products. EASA AD 2011-
0178R1, dated March 6, 2012, corrected March 7, 2012, states:

    During an approach phase, the flight crew of an A330 aeroplane 
had to perform a free-fall extension of the left-hand (LH) MLG.
    Rupture of the LH MLG retraction actuator piston rod was found 
near the rod attachment point. The inspection revealed at the 
location of the rupture the presence of corrosion resulting from 
incorrect application of the anticorrosion protection, and 
circumferential cracks resulting from normal operational loading 
effects.
    Since the above rupture, new cases of crack propagation along 
the length of the piston rod occurred. These ruptures led to a non-
damped extension of the landing gear. Fully

[[Page 7099]]

extended, the landing gear assembly was submitted to high loads 
jeopardizing its structural integrity.
    This condition, if not detected and corrected, could lead to MLG 
failure during landing or roll-out and consequent damage to the 
aeroplane and injury to occupants.
    DGAC France issued AD F-2005-098 (EASA approval 2005-5887) [and 
AD F-2005-099 (EASA approval 2005-5888)] to address this unsafe 
condition [the FAA issued AD 2004-16-01, Amendment 39-13757 (69 FR 
46979, August 4, 2004)]. Since that [DGAC France] AD was issued, the 
results of extensive investigation determined that the presence of 
water in the internal volume of the piston rod can lead to the 
formation of ice which represents a potential source of high 
magnitude tensile hoop stresses in the material of the rod, leading 
to propagation of longitudinal crack in the body of the piston rod.
    Prompted by these findings, EASA issued AD 2006-0301, partially 
retaining the requirements of DGAC France AD F-2005-099, which was 
superseded, and to revise the inspection requirements as follows:
    a. Extend the repetitive inspections interval for the removal of 
fluid from the internal volume of the piston rod using flight cycles 
in lieu of flight hours as this better represents the mechanism for 
the accumulation of water within the piston rod.
    b. Remove the preliminary visual inspection from the ultrasonic 
longitudinal inspection of the upper end of the piston rod.
    c. Add a new one-time ultrasonic longitudinal and 
circumferential inspection of the full piston rod length to 
eliminate any parts that exhibit severe corrosion along the internal 
length of the piston rod.
    d. Require installation of new design hollow piston rod Part 
Number (P/N) 114256328 (Airbus mod. 52980--SB A340-32-4222 Revision 
01) without a vent hole, thus eliminating moisture ingress as the 
terminating action.
    EASA AD 2006-0301 was later revised:

--at revision 01, to correct a number of typographical errors and to 
add reference to Airbus SB A340-32-4212 Revision 04, and
--at revision 02 to extend the inspections threshold from 3 to 6 
years in service usage for retraction actuator piston rod P/N 
114256321 issue 06 which was re-identified to P/N 114256326 issue 01 
in accordance with the instructions of Airbus SB A340-32-4260.

    More recently, the sampling of piston rod P/N 114256326 issue 1 
and P/N 114256321 issue 06 have confirmed the need to replace all 
retraction actuator piston rods with a piston rod P/N114256328.
    For the reasons described above, this [EASA] AD at original 
issue retained the requirements of EASA AD 2006-0301R2 (https://ad.easa.europa.eu/blob/easa_ad_2006_0301_R2_superseded.pdf/AD_2006-0301R2_1), which is superseded, and required the replacement 
of all retraction actuator piston rods with a piston rod P/N 
114256328, which constitutes terminating action to the repetitive 
requirements of this AD.
    This [EASA] AD is revised to clarify that aeroplanes on which 
Airbus mod. 52980 has been embodied in production are not required 
to accomplish the reidentification of MLG retraction actuator P/N 
114256002-055 which is mentioned in the accomplishment instructions 
of Airbus SB A340-32-4222 Revision 03.
    This [EASA] AD has been republished to correct a typographical 
mistake of the applicable Airbus SB number in the Applicability (in 
the Note) and in the Reason sections of this [EASA] AD.

Relevant Service Information

    Airbus has issued the following service bulletins.
     Airbus Mandatory Service Bulletin A330-32-3173, Revision 
05, dated September 26, 2008.
     Airbus Mandatory Service Bulletin A330-32-3180, Revision 
03, dated January 28, 2011.
     Airbus Mandatory Service Bulletin A340-32-4212, Revision 
05, dated September 26, 2008.
     Airbus Mandatory Service Bulletin A340-32-4222, Revision 
03, dated January 28, 2011.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    EASA AD 2011-0178R1, dated March 6, 2012, corrected March 7, 2012 
(for Model A340-200 and -300 series airplanes); and AD 2011-0179R1, 
dated March 6, 2012 (for Model A330-200 and -300 series airplanes); 
require replacement of the retraction actuator within 10 flight cycles 
if the findings of the ultrasonic inspection of the retraction actuator 
piston rod end are between 75% and 90% FSH (full screen height) and 
between 5 and 7 in time base. However, paragraph (n) of this proposed 
AD would require replacement of the retraction actuator before further 
flight if the findings of the ultrasonic inspection of the retraction 
actuator piston rod end are higher than 75% and between 5 and 7 in time 
base.
    EASA AD 2011-0178R1, dated March 6, 2012, corrected March 7, 2012 
(for Model A340-200 and -300 series airplanes); and AD 2011-0179R1, 
dated March 6, 2012 (for Model A330-200 and -300 series airplanes); 
require replacement of the retraction actuator within 10 landings if 
the findings of the one-time ultrasonic circumferential inspection of 
the full-length chromed part of the piston rod give an indication 
between 75% and 90% FSH and between 7 and 9.5 in time base. However, 
paragraph (p)(2) of this proposed AD would require replacement of the 
retraction actuator before further flight if inspection findings are 
higher than 75% FSH and between 7 and 9.5 in time base.
    We have determined that, because of the safety implications and 
consequences associated with those findings, the actuator must be 
replaced before further flight. These differences have been coordinated 
with EASA.

Costs of Compliance

    We estimate that this proposed AD affects 24 Model A330-200 and -
300 series airplanes of U.S. registry. There are no Model A340-200 and 
-300 series airplanes of U.S. registry.
    We estimate that it would take about 67 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 
$56,000 per product (2 actuators). Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $1,480,680, or 
$61,695 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 38 work-hours and require parts costing $56,000 (2 
actuators), for a cost of $59,230 per product. We have no way of 
determining the number of aircraft that might need these actions.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

[[Page 7100]]

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 proposed AD 
is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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 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.
    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.

List of Subjects in 14 CFR Part 39

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

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

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 removing airworthiness directive (AD) 
2004-16-01, Amendment 39-13757 (69 FR 46979, August 4, 2004), and 
adding the following new AD:

Airbus: Docket No. FAA-2014-0012; Directorate Identifier 2012-NM-
007-AD.

(a) Comments Due Date

    We must receive comments by March 24, 2014.

(b) Affected ADs

    This AD supersedes AD 2004-16-01, Amendment 39-13757 (69 FR 
46979, August 4, 2004).

(c) Applicability

    This AD applies to Airbus Model A330-201, -202, -203, -223, -
243, -301, -302, -303, -321, -322, -323, -341, -342, and -343

Gear.

(e) Reason

    This AD was prompted by reports of the piston rods for the MLG 
retraction actuators rupturing during flight. We are issuing this AD 
to prevent cracking of the piston rods for the MLG retraction 
actuators, which could result in rupture of a piston rod, non-damped 
extension of the MLG, high loads on the fully extended MLG, and 
consequent reduced structural integrity of the MLG.
