AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
Incidents have been reported on Britten-Norman BN-2 aircraft,
where cracks were found in the inner shell of the pitot/static
pressure heads. The investigation concluded that these pitot tubes,
supplied by Thales Optronics, could be operated outside their
voltage specification. On December 15th, 2005, CAA [Civil Aviation
Authority] United Kingdom issued AD G-2005-0034 (EASA approval
number 2005-6447), later superseded by EASA AD 2006-0143, to require
inspections and leak tests on Britten-Norman aircraft. Subsequently,
it has been discovered that the same tubes are supplied to EADS-CASA
for installation on C-212 aircraft, one for the pilot side and one
for the co-pilot side. So far, EADS-CASA has not received any report
of cracked pitot tubes from C-212 operators.
This condition, if not corrected, could result in incorrect
readings on the pressure instrumentation, e.g., altimeters, vertical
speed indicators (rate of climb) and airspeed indicators,
potentially leading to navigational errors.
* * * * *
The unsafe condition could reduce the ability of the flightcrew to
maintain the safe flight and landing of the airplane. We are issuing
this AD to require actions to correct the unsafe condition on these
products.
DATES: This AD becomes effective July 16, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 16,
2009.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on February 23, 2009
(74 FR 8043). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Incidents have been reported on Britten-Norman BN-2 aircraft,
where cracks were found in the inner shell of the pitot/static
pressure heads. The investigation concluded that these pitot tubes,
supplied by Thales Optronics, could be operated outside their
voltage specification. On December 15th, 2005, CAA [Civil Aviation
Authority] United Kingdom issued AD G-2005-0034 (EASA approval
number 2005-6447), later superseded by EASA AD 2006-0143, to require
inspections and leak tests on Britten-Norman aircraft. Subsequently,
it has been discovered that the same tubes are supplied to EADS-CASA
for installation on C-212 aircraft, one for the pilot side and one
for the co-pilot side. So far, EADS-CASA has not received any report
of cracked pitot tubes from C-212 operators.
This condition, if not corrected, could result in incorrect
readings on the pressure instrumentation, e.g., altimeters, vertical
speed indicators (rate of climb) and airspeed indicators,
potentially leading to navigational errors.
For the reasons described above, this EASA AD requires the
inspection of the affected pitot tubes, and, if cracks are found,
replacement of those tubes with the new P/N [part number] 212-A0150-
0001 and 212-A0150-0002 pitot tubes.
The unsafe condition could reduce the ability of the flightcrew to
maintain the safe flight and landing of the airplane. You may obtain
further information by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
[[Page 27703]]
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect 32 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $80 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $2,560, or $80 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 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 this AD:
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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

2. The FAA amends Sec. 39.13 by adding the following new AD:
2009-12-04 Construcciones Aeronauticas, S.A. (CASA): Amendment 39-
15927. Docket No. FAA-2009-0005; Directorate Identifier 2008-NM-164-
AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 16,
2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to CASA Model C-212-CB, C-212-CC, C-212-CD,
C-212-CE, C-212-CF, and C-212-DE airplanes, all serial numbers;
certificated in any category; on which pitot tubes having part
number 212-61105.1 or 212-61105.2 are installed.
Subject
(d) Air Transport Association (ATA) of America Code 34:
Navigation.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``Incidents have been reported on Britten-Norman BN-2 aircraft,
where cracks were found in the inner shell of the pitot/static
pressure heads. The investigation concluded that these pitot tubes,
supplied by Thales Optronics, could be operated outside their
voltage specification. On December 15th, 2005, CAA [Civil Aviation
Authority] United Kingdom issued AD G-2005-0034 (EASA approval
number 2005-6447), later superseded by EASA AD 2006-0143, to require
inspections and leak tests on Britten-Norman aircraft. Subsequently,
it has been discovered that the same tubes are supplied to EADS-CASA
for installation on C-212 aircraft, one for the pilot side and one
for the co-pilot side. So far, EADS-CASA has not received any report
of cracked pitot tubes from C-212 operators.
``This condition, if not corrected, could result in incorrect
readings on the pressure instrumentation, e.g., altimeters, vertical
speed indicators (rate of climb) and airspeed indicators,
potentially leading to navigational errors.
``For the reasons described above, this EASA AD requires the
inspection of the affected pitot tubes, and, if cracks are found,
replacement of those tubes with the new P/N [part number] 212-A0150-
0001 and 212-A0150-0002 pitot tubes.
The unsafe condition could reduce the ability of the flightcrew to
maintain the safe flight and landing of the airplane.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 1 month or 300 flight hours after the effective date
of this AD, whichever occurs first: Perform a detailed inspection of
the affected pitot tubes and static inlets for radial cracking
around the top lip of the dynamic port, in accordance with the
instructions of Chapter 5 of the CASA C-212 Series 100/200
Maintenance Manual, Revision 2, dated June 11, 2002. Repeat the
inspection thereafter at intervals not to exceed 300 flight hours.
(2) If any crack is found during any inspection required by
paragraph (f)(1) of this AD, before further flight, replace the
pitot tube with a new pitot tube having P/N 212-A0150-0001 or 212-
A0150-0002 in accordance with the instructions of CASA Service
Bulletin SB-212-34-11, Revision 1, dated February 27, 2008.
Replacement of both pitot tubes having part number 212-61105.1 and
212-61105.2 with new tubes terminates the repetitive inspections
required by paragraph (f)(1) of this AD.
FAA AD Differences
