[Docket No. FAA-2011-0913; Directorate Identifier 2011-NM-031-AD;
Amendment 39-17010; AD 2012-07-04]

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 680 airplanes. This AD was prompted by a
false cross-feed command to the right-hand fuel control card, due to
the cross-feed inputs on the left- and right-hand fuel control cards
being connected together and causing an imbalance of fuel between the
left and right wing tanks. This AD requires adding diodes to the fuel
cross-feed wiring, and revising the airplane flight manual to include
procedures to use when the left or right generator is selected OFF. We
are issuing this AD to prevent lateral imbalance of the airplane,
resulting from uncontrolled fuel cross-feed, which can be corrected by
deflecting the aileron trim; deflecting the aileron trim increases the
pilot's workload and could exceed the airplane's limitation in a short
period of time, resulting in reduced controllability of the airplane.

DATES: This AD is effective May 15, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of May 15, 2012.

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 August 31, 2011 (76
FR 54141), and proposed to require adding diodes to the fuel cross-feed
wiring, and revising the airplane flight manual to include procedures
to use when the left or right generator is selected OFF.

Comments

We gave the public the opportunity to participate in developing
this AD. The following presents the comments received from Cessna
Aircraft Company (Cessna), the manufacturer, on the NPRM (76 FR 54141,
August 31, 2011), and the FAA's response to each comment.

Requests To Correct References to Airplane Flight Manual (AFM)
Revisions and Temporary Changes (TCs) in Paragraph (h) of This AD

Cessna commented that the NPRM (76 FR 54141, August 31, 2011) has
incorrect references to certain AFM TCs, does not refer to certain
applicable AFM TCs, and incorrectly addresses the procedure change in
the recently FAA-approved Revision 10, dated June 30, 2011, of the
Cessna 680 Citation Sovereign AFM. We infer that Cessna requested that
we correct references to the AFM revisions and TCs in paragraph (h) of
the NPRM.
Cessna also commented that the text for AFM revision 68FM-10, dated
June 30, 2011, of the Cessna 680 Citation Sovereign AFM, does not
include the instruction to pull the fuel pump circuit breakers, which
was part of the TC, and is not necessary once the modification
specified in Cessna Service Bulletin 680-24-11, dated December 16,
2010, is done.
Cessna further commented that the wording of the NPRM (76 FR 54141,
August 31, 2011) is incorrect in its reference to Cessna TC TC-R09-13,
dated October 15, 2010, to the Cessna 680 Citation Sovereign AFM,
Revision 9, dated May 24, 2010, and that the TC is applicable until
Revision 10, dated June 30, 2011, of the Cessna 680 Citation Sovereign
AFM, is incorporated into the AFM. Further, the commenter stated that
the remaining TCs for Revision 9, dated May 24, 2010, of the Cessna 680
Citation Sovereign AFM are to be removed when Revision 10 is
incorporated, and there are 3 new TCs for Cessna 680 Citation Sovereign
AFM, Revision 10, dated June 30, 2011, that are the same as the
previous TCs for Cessna 680 Citation Sovereign AFM, Revision 9, dated
May 24, 2010.
We agree with Cessna's requests for the reasons given. We have
changed paragraph (h) of this AD to include the updated AFM revisions
and current TCs. However, some operators still use Cessna 680 Citation
Sovereign AFM, Revision 9, dated May 24, 2010, and therefore the TCs
referenced in Cessna 680 Citation Sovereign AFM, Revision 9, dated May
24, 2010, still apply for some affected airplanes. Therefore,

[[Page 21421]]

paragraph (h) of this AD clarifies the changes to the AFM as they apply
to airplanes using Cessna 680 Citation Sovereign AFM, Revision 9, dated
May 24, 2010, and to airplanes using Cessna 680 Citation Sovereign AFM,
Revision 10, dated June 30, 2011. These changes will not result in an
additional burden to the operator.
We have also reviewed Cessna Service Bulletin SB680-24-11, Revision
1, dated November 15, 2011. This service bulletin includes procedures
to address both Cessna 680 Citation Sovereign AFM, Revision 9, dated
May 24, 2010; and Cessna 680 Citation Sovereign AFM, Revision 10, dated
June 30, 2011; and their corresponding AFM actions. We have also
changed paragraph (g) of this AD to reference Cessna Service Bulletin
SB680-24-11, Revision 1, dated November 15, 2011. We also added
paragraph (i) to the AD to give credit for actions accomplished before
the effective date of the AD using Cessna Service Bulletin SB680-24-11,
dated December 16, 2010, and re-identified subsequent paragraphs
accordingly.

Conclusion

We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD with the changes described previously, and minor editorial changes.
We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 54141, August 31, 2011) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 54141, August 31, 2011).

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 198 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

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.
