14 CFR Part 39

[Docket No. FAA-2012-0720; Directorate Identifier 2012-NM-059-AD; 
Amendment 39-17360; AD 2013-04-03]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cessna Aircraft Company Model 750 airplanes. This AD was prompted by 
reports of loss of displayed airspeed. This AD requires inspecting 
certain logic modules to determine if certain cabin altitude/pitot 
static heater module assemblies are installed and replacing those 
assemblies with a new assembly; and revising the Non-Normal Procedures 
Section of the airplane flight manual (AFM) to include procedures for 
resetting the pitot switch in the event of pitot heater failure and for 
total loss of airspeed indication. We are issuing this AD to prevent 
the loss of all displayed airspeed, which could result in reduced 
ability to control the airplane.

DATES: This AD is effective April 11, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publication listed in the AD as of April 11, 2013.

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 published in the Federal Register on July 17, 2012 (77 FR 
41937). That NPRM proposed to require inspecting certain logic modules 
to determine if certain cabin altitude/pitot static heater module 
assemblies are installed and replacing those assemblies with a new 
assembly; and revising the Non-Normal Procedures Section of the AFM to 
include procedures for resetting the pitot switch in the event of pitot 
heater failure and for total loss of airspeed indication.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 41937, July 17, 2012) and the FAA's response to each comment.

Request To Change Compliance Time

    Cessna Aircraft Company (Cessna) requested that the NPRM (77 FR 
41937, July 17, 2012) use the compliance time described in Cessna 
Service Letter SL750-30-08, Revision 1, dated July 11, 2011, of within 
two years or 1,200 flight hours after July 11, 2011 (The issue date of 
Cessna Service Letter SL750-30-08, Revision 1), whichever occurs first. 
Cessna noted that the proposed NPRM compliance time is within 600 
flight hours or one year after the effective date of the AD, whichever 
occurs first. Cessna stated that the NPRM compliance time will extend 
the compliance time beyond what is suggested by Cessna Service Letter 
SL750-30-08, Revision 1, dated July 11, 2011.
    We disagree with the request to change the compliance time. We 
coordinated with Cessna regarding the compliance time difference prior 
to issuing the NPRM (77 FR 41937, July 17, 2012). We have determined 
that a compliance time of within 600 flight hours or one year after the 
effective date of the AD (whichever occurs first) is an appropriate 
compliance time to adequately address the identified unsafe condition. 
If additional data are presented to justify a shorter compliance time, 
we might consider further rulemaking. We have not changed the AD in 
this regard.

Request To Change Logic Module Designators

    Cessna requested that we change the reference designators to the 
logic modules in paragraph (g) of the NPRM (77 FR 41937, July 17, 
2012). Cessna stated that NC006 and NC007 are the correct reference 
designators for the logic modules.
    We agree to change the references because we have determined that 
the commenter's stated references are

[[Page 14641]]

correct. We have changed paragraph (g) of this AD to refer to the logic 
modules as NC006 and NC007.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 41937, July 17, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 41937, July 17, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 210 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection.........................  2 work-hours x $85 per hour              $0            $170         $35,700
                                      = $170.
Revision...........................  1 work-hour x $85 per hour                0              85          17,850
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                   Action                                 Labor cost                Parts cost        product
----------------------------------------------------------------------------------------------------------------
Replacement................................  1 work-hour x $85 per hour = $85...          $4,058          $4,143
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

    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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
