Start Preamble

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, Start Printed Page 78952rough 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.
