The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Airbus Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and Model C4– 605R Variant F airplanes (collectively called A300–600 series airplanes); and Model A310–200 and –300 series airplanes. That supplemental NPRM was published in the Federal Register on May 18, 2006 (71 FR 28821). That supplemental NPRM proposed to require a one-time inspection of the trimmable horizontal stabilizer actuator, corrective actions if necessary, and follow-on repetitive tasks. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been received on the supplemental NPRM or on the determination of the cost to the public. E:\FR\FM\25JYR1.SGM 25JYR1 42022 Federal Register / Vol. 71, No. 142 / Tuesday, July 25, 2006 / Rules and Regulations Explanation of Change to the Supplemental NPRM Paragraph (g) of the supplemental NPRM specifies making repairs using a method approved by either the FAA or ´ ´ the Direction Generale de l’Aviation Civile (DGAC) (or its delegated agent). The European Aviation Safety Agency (EASA) has assumed responsibility for the airplane model[s] subject to this AD. Therefore, we have revised paragraph (g) of this AD to specify making repairs using a method approved by either the FAA or the EASA (or its delegated agent). described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD with the change Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. ESTIMATED COSTS Action Average labor rate per hour Work hours Inspection .......................... Repetitive follow-on tasks .. 3 12 $80 80 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. cprice-sewell on PROD1PC66 with RULES Regulatory Findings We have 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; VerDate Aug<31>2005 15:39 Jul 24, 2006 Jkt 208001 Cost per airplane None required $0 .................... $240 .................................. $960, per inspection cycle (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) 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.

Discussion

The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to all Airbus
Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-
605R Variant F airplanes (collectively called A300-600 series
airplanes); and Model A310-200 and -300 series airplanes. That
supplemental NPRM was published in the Federal Register on May 18, 2006
(71 FR 28821). That supplemental NPRM proposed to require a one-time
inspection of the trimmable horizontal stabilizer actuator, corrective
actions if necessary, and follow-on repetitive tasks.

Comments

We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.

[[Page 42022]]

Explanation of Change to the Supplemental NPRM

Paragraph (g) of the supplemental NPRM specifies making repairs
using a method approved by either the FAA or the Direction
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) (or its delegated
agent). The European Aviation Safety Agency (EASA) has assumed
responsibility for the airplane model[s] subject to this AD. Therefore,
we have revised paragraph (g) of this AD to specify making repairs
using a method approved by either the FAA or the EASA (or its delegated
agent).

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the AD.

Costs of Compliance

The following table provides the estimated costs for U.S. operators
to comply with this AD.

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 have 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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Inspection

(g) At the applicable time specified in paragraph (g)(1) or
(g)(2) of this AD, do a detailed inspection of specified components
of the THSA in accordance with paragraph 1.E.(2)(a) and the
Accomplishment Instructions of the applicable service bulletin.
Repair any discrepancy before further flight in accordance with a
method approved by the Manager, International Branch, ANM-116,
Transport Airplane Directorate, FAA; or the European Aviation Safety
Agency (EASA) (or its delegated agent). TRW Aeronautical Systems/
Lucas Aerospace Component Maintenance Manual 27-44-13, dated
September 14, 2001, is one acceptable method for the repair.
(1) If the flight hours accumulated on the THSA can be
positively determined: Inspect at the earlier of:
(i) Before the accumulation of 47,000 total flight hours on the
THSA, or within 600 flight hours after the effective date of this
AD, whichever occurs later.
(ii) Within 25 years since the THSA was new or within 600 flight
hours after the effective date of this AD, whichever occurs later.
(2) If the flight hours accumulated on the THSA cannot be
positively determined: Inspect before the accumulation of 47,000
total flight hours on the airplane, or within 600 flight hours after
the effective date of this AD, whichever occurs later.

Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''

Follow-on Repetitive Tasks

(h) After the inspection required by paragraph (g) of this AD:
Do the repetitive tasks in accordance with the Accomplishment
Instructions and at the times specified in paragraph 1.E.(2)(b) of
the service bulletin, as applicable, except as provided by paragraph
(i) of this AD. The repetitive tasks are valid only until the THSA
operational life exceeds 65,000 flight hours, 40,000 flight cycles,
or 25 years, whichever occurs first. Before the THSA is operated
beyond these extended life goals, it must be replaced with a new
THSA, except as required by paragraph (i) of this AD.

THSA Replacement

(i) For any THSA, whether discrepant or not, that is replaced
with a new THSA: Within 47,000 flight hours or 25 years, whichever
occurs first, after the THSA is replaced, do the applicable tasks
specified in paragraph 1.E.(2)(a) and the Accomplishment
Instructions of the applicable service bulletin. Thereafter repeat
the tasks within the repetitive intervals specified in paragraph
1.E.(2)(b) of the applicable service bulletin.

Alternative Methods of Compliance (AMOCs)

(j)(1) The Manager, International Branch, ANM-116, has the
authority to approve AMOCs for this AD, if requested in accordance
with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with 14 CFR
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
