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number 2005-6447), later superseded by EASA AD 2006-0143, to require 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.

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

    Note:  This AD differs from the MCAI and/or service information 
as follows: No differences.
