Airworthiness Directives; Cessna Model 560 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Cessna Model 560 airplanes. This AD requires installing new 
minimum airspeed placards to notify the flightcrew of the proper 
airspeeds for operating in both normal and icing conditions. This AD 
also requires revising the airplane flight manual to provide 
limitations and procedures for operating in icing conditions, for 
operating with anti-ice systems selected ``on'' independent of icing 
conditions, and for recognizing and recovering from inadvertent stall. 
This AD also provides an optional terminating action for the placard 
installation. This AD results from an evaluation of in-service 
airplanes following an accident. The evaluation indicated that some 
airplanes may have an improperly adjusted stall warning system. We are 
issuing this AD to prevent an inadvertent stall due to the inadequate 
stall warning margin provided by an improperly adjusted stall warning 
system, which could result in loss of controllability of the airplane.

DATES: This AD becomes effective November 30, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 30, 
2007.
    We must receive comments on this AD by January 14, 2008.

SUPPLEMENTARY INFORMATION: 

Discussion

    We have evaluated five in-service airplanes to examine the settings 
for the angle-of-attack (AOA)/stall warning system, following an 
accident that occurred on a Cessna Model 560 (Citation V) airplane 
during an instrument landing approach in icing conditions. The 
evaluation indicated that some airplanes may have an improperly 
adjusted stall warning system. All five of the airplanes exhibited an 
out-of-tolerance condition with respect to the margin between the stall 
warning and pre-stall roll-off. On two of the airplanes, the stall 
warning system provided an inadequate airspeed margin between the stall 
warning and stall. An inadvertent stall due to the inadequate stall 
warning margin provided by an improperly adjusted stall warning system, 
if not corrected, could result in loss of controllability of the 
airplane.

    TCs 56FMA TC-R11-16, 56FMA TC-R11-20, 560FM TC-R13-08, and 560FM 
TC-R13-09 provide procedures for exterior inspection of the wings. TCs 
56FMA TC-R11-17 and 560FM TC-R13-10 provide procedures for the surface 
deice system. TCs 56FMA TC-R11-19 and 560FM TC-R13-12 provide emergency 
procedures for an inadvertent stall (buffet/roll-off). TCs 56FMA TC-
R11-21 and 560FM TC-R13-13 provide procedures for safe flight under 
icing conditions. TCs 56FMA TC-R11-23, 56FMA TC-R11-24, 56FMA TC-R11-
25, 56FMA TC-R11-26, 560FM TC-R13-14, 560FM TC-R13-15, 560FM TC-R13-16, 
and 560FM TC-R13-17 provide procedures for determining approach and 
landing data. TCs 56FMA TC-R11-27 and 560FM TC-R13-18 provide 
operational limitations for minimum airspeeds in normal and icing 
conditions. TCs 56FMA TC-R11-28, 56FMA TC-R11-29, 56FMA TC-R11-30, 
560FM TC-R13-19, and 560FM TC-R13-20 provide procedures for determining 
landing speed and distance factors with residual ice or anti-ice 
systems selected ``on'' independent of icing conditions.
    We have reviewed Cessna Service Bulletin SB560-34-143, dated 
September 7, 2007, including Attachment and Service Bulletin 
Supplemental Data. The service bulletin describes procedures for 
installing new minimum airspeed placards to notify the flightcrew of 
the proper airspeeds for operating in normal and icing conditions. The 
service bulletin also describes procedures for incorporating certain 
TCs into the AFM and sending a maintenance transaction report to the 
manufacturer.
    We have also reviewed Cessna Alert Service Letters ASL560-34-34 
(for airplanes equipped with a single AOA system) and ASL560-34-35 (for 
airplanes equipped with a dual AOA system), both Revision 1, both dated 
October 2, 2007, both including Attachments. The service letters 
describe procedures for doing a functional test of the AOA system, 
which involves determining whether the calibration of the AOA system is 
correct and adjusting the calibration settings if necessary. The 
service letters also describe procedures for removing the temporary 
airspeed placard installed in accordance with Cessna Service Bulletin 
SB560-34-143 and submitting the AOA system test data sheet and a 
maintenance transaction report to the manufacturer.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other airplanes of the same type design. For this reason, we 
are issuing this AD to prevent an inadvertent stall due to the 
inadequate stall warning margin provided by an improperly adjusted 
stall warning system, which could result in loss of controllability of 
the airplane. This AD requires accomplishing the actions specified in 
the service information described previously, except as discussed under 
``Difference between the AD and Service Information.''

Difference Between the AD and Service Information

    Although the Accomplishment Instructions of Cessna Service Bulletin 
SB560-34-143 and Cessna Alert Service Letters ASL560-34-34 and ASL560-
34-35 describe procedures for submitting a maintenance transaction 
report to the manufacturer, this AD does not require that action. 
However, if operators accomplish the functional test as specified in 
Cessna Alert Service Letters ASL560-34-34 and ASL560-34-35, this AD 
requires submitting the AOA system test data sheet to the manufacturer.

Interim Action

    We consider this AD interim action. We are currently considering 
requiring a functional test of the AOA system to adjust the calibration 
settings of the AOA system, which, in addition to the AFM revisions, 
would constitute terminating action for the placard installation 
required by this AD. However, the planned compliance time for the 
functional test would allow enough time to provide notice and 
opportunity for prior public comment on the merits of the functional 
test.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and

[[Page 64137]]

that good cause exists to make this AD effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2007-0190; Directorate Identifier 2007-NM-234-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
