ACTION: Notice of proposed rulemaking (NPRM). AGENCY: VerDate Aug<31>2005 13:29 Jan 18, 2006 Jkt 208001 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Aerospatiale Model ATR42 airplanes and Model ATR72 airplanes. This proposed AD would require installing protective ramps on trim panel 110VU; and inspecting the protective guard of the standby pitch trim switch to determine if it is missing, damaged, or ineffective, and doing the corrective action if necessary. This proposed AD results from a finding that the protective guard of the standby pitch trim switch, which is installed on the center pedestal, could be damaged or missing. We are proposing this AD to prevent inadvertent activation of the standby pitch trim, which could result in pitch trim runaway and consequent reduced controllability of the airplane.

Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Aerospatiale Model ATR42 and Model ATR72 airplanes. The DGAC advises that the protective guard of the standby pitch trim switch (18CG), which is installed on the center pedestal, could be damaged or missing. In some cases, a damaged protective guard, even if engaged, may not prevent inadvertent activation of the standby pitch trim. This condition, if not corrected, could result in pitch trim runaway and consequent reduced controllability of the airplane. Relevant Service Information Aerospatiale has issued Avions de Transport Regional Service Bulletin ATR42–92–0010, Revision 1, dated March 11, 2003 (for Model ATR42 airplanes); and Service Bulletin ATR72– 92–1010, Revision 1, dated March 11, 2003 (for Model ATR72 airplanes). The service bulletins describe the following procedures: E:\FR\FM\19JAP1.SGM 19JAP1 3024 Federal Register / Vol. 71, No. 12 / Thursday, January 19, 2006 / Proposed Rules • Installing protective ramps on trim panel 110VU. • Checking the protective guard of the standby pitch trim switch (18CG) to determine if it is missing, damaged, or ineffective. (The protective guard is ineffective if there is trim movement when the protective guard is engaged and the standby pitch trim switch is activated.) • Doing the corrective action if necessary, which includes replacing a damaged or ineffective protective guard with a new part or installing a new part if the protective guard is missing. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive 2003–106(B) R1, dated April 16, 2003, to ensure the continued airworthiness of these airplanes in France. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Clarification of Inspection Terminology.’’ U.S. operators is $36,570, or $530 per airplane. PART 39—AIRWORTHINESS DIRECTIVES Authority for This Rulemaking 1. The authority citation for part 39 continues to read as follows: 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 The ‘‘check’’ of the protective guard specified in the Aerospatiale service bulletins is referred to as a ‘‘general visual inspection’’ in this proposed AD. We have included the definition for a general visual inspection in a note in this proposed AD. We have 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 that the 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); 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 proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. Costs of Compliance List of Subjects in 14 CFR Part 39 This proposed AD would affect about 69 airplanes of U.S. registry. The proposed actions would take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Required parts would cost about $465 per airplane. Based on these figures, the estimated cost of the proposed AD for Air transportation, Aircraft, Aviation safety, Safety. hsrobinson on PROD1PC70 with PROPOSALS Clarification of Inspection Terminology VerDate Aug<31>2005 13:29 Jan 18, 2006 Jkt 208001 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

But you may submit a request for a meeting by writing to the Waterways Management Division at the address under ADDRESSES explaining why one would be beneficial. If we determine that one would aid this rulemaking, we will hold one at a time and place announced by a later notice in the Federal Register. Background and Purpose As part of a waterfront revitalization effort the Village of Haverstraw is encouraging waterfront use by the general public. This proposed rule is in response to a request made by the Village of Haverstraw to ensure the safe navigation of increased vessel traffic expected to arrive along the village waterfront due to this revitalization effort. The Coast Guard is designating the area as a special anchorage area in PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 3025 accordance with 33 U.S.C. 471. In accordance with that statute, vessels will not be required to sound signals or exhibit anchor lights or shapes which are otherwise required by rule 30 and 35 of the Inland Navigation Rules, codified at 33 U.S.C. 2030 and 2035. The proposed special anchorage area will be located on the west side of the Hudson River about 1,800 yards south of Bowline Point, well removed from the channel and located where general navigation will not endanger or be endangered by unlighted vessels. Providing anchorage well removed from the channel and general navigation would greatly increase navigational safety. This special anchorage area is part of a waterfront revitalization project authorized under U.S. Army Corps of Engineers permit number 2004–00596– YR. Discussion of Proposed Rule The proposed rule would create a new special anchorage area located on the Hudson River at the Village of Haverstraw, New York, on Haverstraw Bay. It would include all waters of the Hudson River bound by the following points: 41°11′25.2″ N, 073°57′19.9″ W; thence to 41°11′34.2″ N, 073°57′00.8″ W; thence to 41°11′41.9″ N, 073°57′07.5″ W; thence to 41°11′31.8″ N, 073°57′26.5″ W; thence to 41°11′30.8″ N, 073°57′24.9″ W; thence to the point of origin (NAD 1983). All proposed coordinates are North American Datum 1983 (NAD 83). The special anchorage area would be limited to vessels no greater than 20 meters in length. Vessels not more than 20 meters in length are not required to sound signals as required by rule 35 of the Inland Navigation Rules (33 U.S.C. 2035) nor exhibit anchor lights or shapes required by rule 30 of the Inland Navigation Rules (33 U.S.C 2030) when at anchor in a special anchorage area. Additionally, mariners utilizing the anchorage areas are encouraged to contact local and state authorities, such as the local harbormaster, to ensure compliance with additional applicable state and local laws. Such laws may involve, for example, compliance with direction from the local harbormaster when placing or using moorings within the anchorage. Regulatory Evaluation This proposed rule is not a ‘‘significant regulatory action’’ under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order.

Airworthiness Directives; Aerospatiale Model ATR42 Airplanes and 
Model ATR72 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Aerospatiale Model ATR42 airplanes and Model ATR72 
airplanes. This proposed AD would require installing protective ramps 
on trim panel 110VU; and inspecting the protective guard of the standby 
pitch trim switch to determine if it is missing, damaged, or 
ineffective, and doing the corrective action if necessary. This 
proposed AD results from a finding that the protective guard of the 
standby pitch trim switch, which is installed on the center pedestal, 
could be damaged or missing. We are proposing this AD to prevent 
inadvertent activation of the standby pitch trim, which could result in 
pitch trim runaway and consequent reduced controllability of the 
airplane.

DATES: We must receive comments on this proposed AD by February 21, 
2006.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified us that an 
unsafe condition may exist on certain Aerospatiale Model ATR42 and 
Model ATR72 airplanes. The DGAC advises that the protective guard of 
the standby pitch trim switch (18CG), which is installed on the center 
pedestal, could be damaged or missing. In some cases, a damaged 
protective guard, even if engaged, may not prevent inadvertent 
activation of the standby pitch trim. This condition, if not corrected, 
could result in pitch trim runaway and consequent reduced 
controllability of the airplane.

Relevant Service Information

    Aerospatiale has issued Avions de Transport Regional Service 
Bulletin ATR42-92-0010, Revision 1, dated March 11, 2003 (for Model 
ATR42 airplanes); and Service Bulletin ATR72-92-1010, Revision 1, dated 
March 11, 2003 (for Model ATR72 airplanes). The service bulletins 
describe the following procedures:

[[Page 3024]]

     Installing protective ramps on trim panel 110VU.
     Checking the protective guard of the standby pitch trim 
switch (18CG) to determine if it is missing, damaged, or ineffective. 
(The protective guard is ineffective if there is trim movement when the 
protective guard is engaged and the standby pitch trim switch is 
activated.)
     Doing the corrective action if necessary, which includes 
replacing a damaged or ineffective protective guard with a new part or 
installing a new part if the protective guard is missing.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The DGAC mandated 
the service information and issued French airworthiness directive 2003-
106(B) R1, dated April 16, 2003, to ensure the continued airworthiness 
of these airplanes in France.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for airplanes of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously, except as discussed under ``Clarification of 
Inspection Terminology.''

Clarification of Inspection Terminology

    The ``check'' of the protective guard specified in the Aerospatiale 
service bulletins is referred to as a ``general visual inspection'' in 
this proposed AD. We have included the definition for a general visual 
inspection in a note in this proposed AD.

Costs of Compliance

    This proposed AD would affect about 69 airplanes of U.S. registry. 
The proposed actions would take about 1 work hour per airplane, at an 
average labor rate of $65 per work hour. Required parts would cost 
about $465 per airplane. Based on these figures, the estimated cost of 
the proposed AD for U.S. operators is $36,570, or $530 per airplane.

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 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 that the 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); 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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

    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 Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

Aerospatiale: Docket No. FAA-2006-23635; Directorate Identifier 
2005-NM-245-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by February 
21, 2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Aerospatiale Model ATR42-200, -300, -320, 
and -500 airplanes and Model ATR72-101, -201, -102, -202, -211, -
212, and -212A airplanes, certificated in any category; except those 
on which Airbus Modification 5450 has been incorporated in 
production.

Unsafe Condition

    (d) This AD results from a finding that the protective guard of 
the standby pitch trim switch, which is installed on the center 
pedestal, could be damaged or missing. We are issuing this AD to 
prevent inadvertent activation of the standby pitch trim, which 
could result in pitch trim runaway and consequent reduced 
controllability of the airplane.

Compliance

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

Installation, Inspection, and Corrective Action if Necessary

    (f) Within 4 months after the effective date of this AD: Install 
protective ramps on trim panel 110VU; and do a general visual 
inspection of the protective guard of the standby pitch trim switch 
(18CG) to determine if it is missing, damaged, or ineffective, and 
do the corrective action if applicable; by accomplishing all the 
applicable actions specified in the Accomplishment Instructions of 
Avions de Transport Regional Service Bulletin ATR42-92-0010, 
Revision 1, dated March 11, 2003 (for Model ATR42 airplanes); or 
Avions de Transport Regional Service Bulletin ATR72-92-1010, 
Revision 1, dated March 11, 2003 (for Model ATR72 airplanes), as 
applicable. The corrective action, if required, must be done before 
further flight after the inspection.

    Note 1:  For the purposes of this AD, a general visual 
inspection is: ``A visual examination of an interior or exterior 
area, installation, or assembly to detect obvious damage, failure, 
or irregularity. This level of inspection is made from within 
touching distance unless otherwise specified. A mirror

[[Page 3025]]

may be necessary to ensure visual access to all surfaces in the 
inspection area. This level of inspection is made under normally 
available lighting conditions such as daylight, hangar lighting, 
flashlight, or droplight and may require removal or opening of 
access panels or doors. Stands, ladders, or platforms may be 
required to gain proximity to the area being checked.''

Alternative Methods of Compliance (AMOCs)

    (g)(1) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 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 Sec.  
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.

16, 2003, also addresses the subject of this AD.
