Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2006-23635; Directorate Identifier 2005-NM-245-AD;
Amendment 39-14546; AD 2006-07-19]
RIN 2120-AA64
Airworthiness Directives; Aerospatiale Model ATR42 Airplanes and
Model ATR72 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Aerospatiale Model ATR42 airplanes and Model ATR72 airplanes.
This AD requires 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 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.
DATES: This AD becomes effective May 12, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of May 12, 2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
Room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. 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 notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Aerospatiale
Model ATR42 airplanes and Model ATR72 airplanes. That NPRM was
published in the Federal Register on January 19, 2006 (71 FR 3023).
That NPRM proposed to 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.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the NPRM or on the
determination of the cost to the public.
Explanation of Changes to Applicability
We have corrected the applicability in paragraph (c) of the AD to
reidentify the modification as ``ATR Modification 05450.''
We have revised the applicability in paragraph (f) of the AD to
identify model designations as published in the most recent type
certificate data sheet for the affected models.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
changes described previously. We have determined that these changes
will neither increase the economic burden on any operator nor increase
the scope of the AD.
Costs of Compliance
This AD affects about 69 airplanes of U.S. registry. The required
actions will take about 1 work hour per airplane, at an average labor
rate of $65 per work hour. Required parts will cost about $465 per
airplane. Based on these figures, the estimated cost of the 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 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.

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

Authority: 49 U.S.C. 106(g), 40113, 44701.
[[Page 17701]]
Sec. 39.13 [Amended]

2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2006-07-19 Aerospatiale: Amendment 39-14546. Docket No. FAA-2006-
23635; Directorate Identifier 2005-NM-245-AD.
Effective Date
(a) This AD becomes effective May 12, 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 ATR Modification 05450 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 ATR42-200, -300, -320,
and -500 airplanes); or Avions de Transport Regional Service
Bulletin ATR72-92-1010, Revision 1, dated March 11, 2003 (for Model
ATR72-101, -201, -102, -202, -211, -212, and -212A 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 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.
