ACTION: Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD), VerDate Aug<31>2005 19:28 Dec 23, 2008 Jkt 217001 which applies to certain Cessna Model 560 airplanes. That AD currently requires installing new minimum airspeed placards to notify the flightcrew of the proper airspeeds for operating in both normal and icing conditions. That 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. That AD also provides an optional terminating action for the placard installation. This new AD requires the previously optional terminating action. This AD results from an evaluation of in-service airplanes following an accident. The evaluation indicated that some airplanes might 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 January 28, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of January 28, 2009. On November 30, 2007 (72 FR 64135, November 15, 2007), the Director of the Federal Register approved the incorporation by reference of certain other publications.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2007–23–13, amendment 39–15259 (72 FR 64135, November 15, 2007). The existing AD (AD 2007–23– 13) applies to certain Cessna Model 560 airplanes. That NPRM was published in the Federal Register on August 21, 2008 (73 FR 49359). That NPRM proposed to continue to require installing new minimum airspeed placards to notify the flightcrew of the proper airspeeds for operating in both normal and icing conditions. That NPRM also proposed to continue to require 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. That NPRM also proposed to require an optional terminating action for the placard installation and after accomplishing the terminating action, removing an AFM warning. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been received on the NPRM. Additional Concern Regarding Safety of Flight in Icing Conditions The National Safety Review Board (NTSB) states that based on its review of the NPRM, it is pleased that the FAA has performed a fleet survey and has identified a potential source of inaccuracy in the angle-of-attack (AOA) system. Further, the NTSB states it is pleased that the FAA has proposed requirements for correcting the calibration of the AOA system and providing data regarding the calibration adjustment to the manufacturer. The NTSB concludes that these actions would ensure that the stall warning system provides an accurate stall warning based on original and secondary/icing certification flight testing. However, the NTSB notes that the actions described in this NPRM and in AD 2007–23–13 do not address certain safety recommendations. The NTSB states it is concerned that a reduction in stall warning margin produced by thin, E:\FR\FM\24DER1.SGM 24DER1 78952 Federal Register / Vol. 73, No. 248 / Wednesday, December 24, 2008 / Rules and Regulations rough ice accretions generated by supercooled large droplet icing conditions or icing conditions near the edge of the icing envelope can eliminate or seriously alter stall margin and the alert provided to the flightcrew, even for a properly calibrated AOA system. The NTSB states that utilization of the super-cooled large droplet icing envelope being developed in response to NTSB Safety Recommendation A–96– 54 to evaluate the stall warning margin of the Cessna Model 560 airplanes with thin, rough ice accretions on or aft of the protected surfaces, as recommended by NTSB Safety Recommendation A–07– 17, would provide the best level of safety in all icing condition, and in icing conditions similar to those encountered by the Cessna Model 560 airplane involved in an accident at Pueblo, Colorado. We acknowledge the NTSB’s concerns. The unsafe condition identified in this action is an inadvertent stall due to the inadequate stall warning margin provided by an improperly adjusted stall warning system. This AD addresses that potential unsafe condition. As noted in the NTSB comment, Safety Recommendation A–07–17 addresses the NTSB’s concern with the effect of thin, rough ice accretions on the Cessna Model 560 stall warning system. We have provided to the NTSB the FAA actions responsive to the recommendation. With respect to the application of a large super-cooled large droplet icing envelope to existing airplanes, we have identified, in response to the NTSB Safety Recommendation A–07–16, actions that we have taken and plan to take to ensure the safe operation of existing airplanes equipped with pneumatic deicing boots, such as Cessna Model 560 airplanes. Updates to the NTSB are provided through established procedures. Conclusion We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 538 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this AD. There are about 400 U.S. registered airplanes. ESTIMATED COSTS Action AFM Revision (required by AD 2007–23–13) ................................................................. Placard Installation (required by AD 2007–23–13) ......................................................... Functional Test (new action) ........................................................................................... pwalker on PROD1PC71 with RULES 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. VerDate Aug<31>2005 19:28 Dec 23, 2008 Jkt 217001 Average labor rate per hour Work hours 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); 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.

Airworthiness Directives; Cessna Model 560 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Cessna Model 560 airplanes. That AD 
currently requires installing new minimum airspeed placards to notify 
the flightcrew of the proper airspeeds for operating in both normal and 
icing conditions. That 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. That AD also provides an optional terminating 
action for the placard installation. This new AD requires the 
previously optional terminating action. This AD results from an 
evaluation of in-service airplanes following an accident. The 
evaluation indicated that some airplanes might 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 January 28, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 28, 
2009.
    On November 30, 2007 (72 FR 64135, November 15, 2007), the Director 
of the Federal Register approved the incorporation by reference of 
certain other publications.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2007-23-13, amendment 
39-15259 (72 FR 64135, November 15, 2007). The existing AD (AD 2007-23-
13) applies to certain Cessna Model 560 airplanes. That NPRM was 
published in the Federal Register on August 21, 2008 (73 FR 49359). 
That NPRM proposed to continue to require installing new minimum 
airspeed placards to notify the flightcrew of the proper airspeeds for 
operating in both normal and icing conditions. That NPRM also proposed 
to continue to require 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. 
That NPRM also proposed to require an optional terminating action for 
the placard installation and after accomplishing the terminating 
action, removing an AFM warning.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
received on the NPRM.

Additional Concern Regarding Safety of Flight in Icing Conditions

    The National Safety Review Board (NTSB) states that based on its 
review of the NPRM, it is pleased that the FAA has performed a fleet 
survey and has identified a potential source of inaccuracy in the 
angle-of-attack (AOA) system. Further, the NTSB states it is pleased 
that the FAA has proposed requirements for correcting the calibration 
of the AOA system and providing data regarding the calibration 
adjustment to the manufacturer. The NTSB concludes that these actions 
would ensure that the stall warning system provides an accurate stall 
warning based on original and secondary/icing certification flight 
testing.
    However, the NTSB notes that the actions described in this NPRM and 
in AD 2007-23-13 do not address certain safety recommendations. The 
NTSB states it is concerned that a reduction in stall warning margin 
produced by thin,

[[Page 78952]]

rough ice accretions generated by supercooled large droplet icing 
conditions or icing conditions near the edge of the icing envelope can 
eliminate or seriously alter stall margin and the alert provided to the 
flightcrew, even for a properly calibrated AOA system.
    The NTSB states that utilization of the super-cooled large droplet 
icing envelope being developed in response to NTSB Safety 
Recommendation A-96-54 to evaluate the stall warning margin of the 
Cessna Model 560 airplanes with thin, rough ice accretions on or aft of 
the protected surfaces, as recommended by NTSB Safety Recommendation A-
07-17, would provide the best level of safety in all icing condition, 
and in icing conditions similar to those encountered by the Cessna 
Model 560 airplane involved in an accident at Pueblo, Colorado.
    We acknowledge the NTSB's concerns. The unsafe condition identified 
in this action is an inadvertent stall due to the inadequate stall 
warning margin provided by an improperly adjusted stall warning system. 
This AD addresses that potential unsafe condition.
    As noted in the NTSB comment, Safety Recommendation A-07-17 
addresses the NTSB's concern with the effect of thin, rough ice 
accretions on the Cessna Model 560 stall warning system. We have 
provided to the NTSB the FAA actions responsive to the recommendation. 
With respect to the application of a large super-cooled large droplet 
icing envelope to existing airplanes, we have identified, in response 
to the NTSB Safety Recommendation A-07-16, actions that we have taken 
and plan to take to ensure the safe operation of existing airplanes 
equipped with pneumatic deicing boots, such as Cessna Model 560 
airplanes. Updates to the NTSB are provided through established 
procedures.

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been submitted, and determined that air safety and the 
public interest require adopting the AD as proposed.

Costs of Compliance

    There are about 538 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD. There are about 400 U.S. 
registered airplanes.

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 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); 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.

New Requirements of This AD

Terminating Action

    (i) Within 6 months after the effective date of this AD, do a 
functional test of the angle-of-attack (AOA) system, and adjust the

Cessna Alert Service Letter ASL560-34-34 or ASL560-34-35, both 
Revision 3, both dated March 6, 2008, both including Attachments, as 
applicable. As of the effective date of this AD, only Revision 3 may 
be used. Doing the functional test of the AOA system, adjusting the 
calibration settings of the AOA system as applicable, and submitting 
the AOA system test data as specified in paragraph (j) of this AD, 
terminates the placard installation required by paragraph (g) of 
this AD.

    Note 2: Maintenance Manual Revision 24 of Cessna 560 Maintenance

include the AOA test data, the airplane serial number and 
registration number, and the number of landings and flight hours on 
the airplane. Under the provisions of the Paperwork Reduction Act 
(44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) 
has approved the information collection requirements contained in 
this AD and has assigned OMB Control Number 2120-0056.
    (1) If the functional test was done after November 30, 2007: 
Submit the report within 30 days after doing the functional test.
    (2) If the inspection was accomplished prior to November 30, 
2007: Submit the report within 30 days after November 30, 2007.

Removal of Warning From the Limitations Section of the AFM

    (k) For airplanes on which the actions required by paragraph (i) 
of this AD have been done: Within 30 days after doing the actions 
required by paragraph (i) of this AD or within 30 days after the 
effective date of this AD, whichever occurs later, revise the 
Limitations Section of the AFM by removing the following Warning 
statement:

``Warning: Stick Shaker May Not Activate Prior to Buffet/Roll-Off If 
Airspeed Is Reduced Below the Appropriate Minimum Speed.''

No Maintenance Transaction Report Required for Cessna Service Letters

    (l) Cessna Alert Service Letters ASL560-34-34 and ASL560-34-35, 
both Revision 1, both dated October 2, 2007, both including 
Attachments; and Cessna Alert Service Letters ASL560-34-34 and 
ASL560-34-35, both Revision 3, both dated March 6, 2008, both

accordance with Cessna Alert Service Letter ASL560-34-34 or ASL560-
34-35, both Revision 2, both dated January 11, 2008, both including 
Attachments, are considered acceptable for compliance with the 
corresponding action specified in paragraph (i) of this AD.
