AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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number 2005-6447), later superseded by EASA AD 2006-0143, to require 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. The proposed AD 
would require actions that are intended to address the unsafe condition 
described in the MCAI.

DATES: We must receive comments on this proposed AD by March 25, 2009.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2008-0155, dated August 11, 2008 (referred to 
after this as ``the MCAI''), 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.

Relevant Service Information

    CASA has issued Chapter 5 of the C-212 Series 100/200 Maintenance 
Manual, Revision 2, dated June 11, 2002; and Service Bulletin SB-212-
34-11, Revision 1, dated February 27, 2008. The actions described in 
this service

[[Page 8044]]

information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 32 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on 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 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 this 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.

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    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 FAA amends Sec.  39.13 by adding the following new AD:

Construcciones Aeronauticas, S.A. (CASA): Docket No. FAA-2009-0005; 
Directorate Identifier 2008-NM-164-AD.

Comments Due Date

    (a) We must receive comments by March 25, 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.
