ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes); and Model A310 series airplanes. This proposed AD was prompted by a report of an uncommanded slide back of the co-pilot seat to the end stop position. This proposed AD would require a one-time inspection for a part number, a tensile test of the affected seats, and corrective actions if necessary. We are proposing this AD to detect and prevent unwanted movement of a pilot or co-pilot seat in the horizontal direction, which could lead to inadvertent input on the flight control commands and possibly result in loss of controllability of the airplane.

Discussion The European Aviation Safety Agency (EASA), which is the aviation authority for Member States of the European Community, has issued EASA Airworthiness Directive 2012–0102, dated June 8, 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: During a steep climb manoeuvre that was flown with a high pitch (25°) for training of ground threat avoidance, an Airbus A310 aeroplane experienced an uncommanded slide back of the co-pilot seat to the end stop position. Investigation revealed that on the affected seat, the disc key inside the clutch was broken. SOGERMA Service Bulletin (SB) No 2510112–25–813, which addresses the previous end stop switch issue and which is covered by EASA AD 2010–0070 [which corresponds to FAA AD 2011–06–09, Amendment 39–16634 (76 FR 15805, March 22, 2011)] had been accomplished on this seat, but due to seizure, the key failure was not detected at time. This broken disc key caused a jamming between the gear and the shaft of the clutch. Despite this failure, the torque transmission between the gear and the shaft was sufficient for normal operation, but not to keep the seat in locked position during climbing, due to the high longitudinal loads generated by the high aeroplane incidence. This condition, if not detected and corrected, could cause the pilot to lose contact with the controls, leading to an inadvertent input on the flight control commands during take-off or climb, possibly resulting in loss of control of the aeroplane. For the reasons described above, this [EASA] AD requires a one-time inspection [part number (P/N) inspection of the seats and tensile test] of the affected seats and, depending on findings, accomplishment of applicable corrective action(s) [replacing the seat or modifying the seat by replacing actuator P/N RT19H4FX with a new actuator]. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Alert Operators Transmission A25W001–12, dated June 6, 2012; and EADS SOGERMA has issued Inspection Service Bulletin E:\FR\FM\10DEP1.SGM 10DEP1 73344 Federal Register / Vol. 77, No. 237 / Monday, December 10, 2012 / Proposed Rules 2510112–25–898, dated April 25, 2012. 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. mstockstill on DSK4VPTVN1PROD with Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 161 products of U.S. registry. We also estimate that it would take about 1 work-hour 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 $4,523 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $741,888, or $4,608 per product. 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. VerDate Mar<15>2010 16:22 Dec 07, 2012 Jkt 229001 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and 
Model A300 C4-605R Variant F airplanes (collectively called Model A300-
600 series airplanes); and Model A310 series airplanes. This proposed 
AD was prompted by a report of an uncommanded slide back of the co-
pilot seat to the end stop position. This proposed AD would require a 
one-time inspection for a part number, a tensile test of the affected 
seats, and corrective actions if necessary. We are proposing this AD to 
detect and prevent unwanted movement of a pilot or co-pilot seat in the 
horizontal direction, which could lead to inadvertent input on the 
flight control commands and possibly result in loss of controllability 
of the airplane.

DATES: We must receive comments on this proposed AD by January 24, 
2013.

Discussion

    The European Aviation Safety Agency (EASA), which is the aviation 
authority for Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0102, dated June 8, 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:

    During a steep climb manoeuvre that was flown with a high pitch 
(25[deg]) for training of ground threat avoidance, an Airbus A310 
aeroplane experienced an uncommanded slide back of the co-pilot seat 
to the end stop position.
    Investigation revealed that on the affected seat, the disc key 
inside the clutch was broken. SOGERMA Service Bulletin (SB) No 
2510112-25-813, which addresses the previous end stop switch issue 
and which is covered by EASA AD 2010-0070 [which corresponds to FAA 
AD 2011-06-09, Amendment 39-16634 (76 FR 15805, March 22, 2011)] had 
been accomplished on this seat, but due to seizure, the key failure 
was not detected at time. This broken disc key caused a jamming 
between the gear and the shaft of the clutch. Despite this failure, 
the torque transmission between the gear and the shaft was 
sufficient for normal operation, but not to keep the seat in locked 
position during climbing, due to the high longitudinal loads 
generated by the high aeroplane incidence.
    This condition, if not detected and corrected, could cause the 
pilot to lose contact with the controls, leading to an inadvertent 
input on the flight control commands during take-off or climb, 
possibly resulting in loss of control of the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time inspection [part number (P/N) inspection of the seats and 
tensile test] of the affected seats and, depending on findings, 
accomplishment of applicable corrective action(s) [replacing the 
seat or modifying the seat by replacing actuator P/N RT19H4FX with a 
new actuator].

    You may obtain further information by examining the MCAI in the AD 
docket.

[[Page 73344]]

2510112-25-898, dated April 25, 2012. 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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 161 products of U.S. registry. We also estimate that 
it would take about 1 work-hour 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 $4,523 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
parts. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $741,888, or $4,608 per product.

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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

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

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


Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2012-1224; Directorate Identifier 2012-NM-
112-AD.

 (a) Comments Due Date

    We must receive comments by January 24, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-
622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F 
airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, 
and -325 airplanes; certificated in any category; all manufacturer 
serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/
Furnishings.

(e) Reason

    This AD was prompted by a report of an uncommanded slide back of 
the co-pilot seat to the end stop position. We are issuing this AD 
to detect and prevent unwanted movement of a pilot or co-pilot seat 
in the horizontal direction, which could lead to inadvertent input 
on the flight control commands possibly resulting in loss of 
controllability of the airplane.

(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) Part Number (P/N) Inspection

    Within 6 months after the effective date of this AD, except as 
provided by paragraph (h) of this AD: Do an inspection to determine 
the part number of each SOGERMA pilot and co-pilot seat installed on 
the airplane. As an alternative, a review of the maintenance or 
delivery records may be used to determine the part number of the 
pilot and co-pilot seat if the part number can be positively 
determined.

(h) Seats That Have Been Previously Tested or Modified

    SOGERMA pilot and co-pilot seats having P/N 2510112 series (all 
suffixes) or P/N 2510113 series (all suffixes) that, before the 
effective date of this AD, have already passed the tensile test 
specified in paragraph (i) of this AD, or have been modified in 
accordance with the Accomplishment Instructions of EADS SOGERMA 
Inspection Service Bulletin 2510112-25-898, dated April 25, 2012, 
are not required to be tested, and are considered to be compliant 
with the requirements of this AD.

(i) Tensile Test

    If, during the inspection required by paragraph (g) of this AD, 
the part number of a seat is identified as P/N 2510112 series (all 
suffixes), or P/N 2510113 series (all suffixes): Within 6 months 
after the effective date of this AD, do a tensile test on that seat 
in accordance with Airbus Alert Operators Transmission (AOT) 
A25W001-12, dated June 6, 2012.

(j) Replacement or Modification

    If the tensile test sample does not break off while performing 
the test required by paragraph (i) of this AD, before further 
flight, do one of the actions specified in paragraph (j)(1) or 
(j)(2) of this AD.
    (1) Replace the affected seat with a new or serviceable seat 
that has passed the tensile test specified in paragraph (i) of this 
AD. Do the replacement in accordance with Airbus AOT A25W001-12, 
dated June 6, 2012.
    (2) Modify the seat by replacing actuator P/N RT19H4FX of the 
affected seat, in accordance with the Accomplishment Instructions of 
EADS SOGERMA Inspection Service Bulletin 2510112-25-898, dated April 
25, 2012; or Airbus AOT A25W001-12, dated June 6, 2012.
