ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require you to install a placard that prohibits flight into known icing conditions and install a placard that increases published speed on approach 17 mph (15 knots) in case of an inadvertent encounter with icing. This proposed AD was prompted by an investigation of recent and historical icing-related accidents and incidents for the products listed above. We are proposing this AD to prohibit flight into known icing conditions as well as increase the approach speed in case of an inadvertent encounter with icing. This condition, if not corrected, could result in unusual flight characteristics that could lead to loss of control after flight into known icing conditions or an inadvertent encounter with icing conditions. Based on the data, an example of the unusual flight characteristics seen in many of the accidents is high sink speeds that resulted in a hard landing. DATES: We must receive comments on this proposed AD by July 18, 2011. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2011–0562; Directorate Identifier 2011– CE–015–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We are proposing this AD as a result of an investigation of 51 recent and historical icing-related accidents and incidents over the last 30 years that resulted in 36 fatalities for aircraft listed in Cessna Aircraft Company (Cessna) Service Bulletin MEB97–4. The nonfatal events usually resulted in injuries and substantial aircraft damage. The National Transportation Safety Board dockets showed for two non-fatal landing events airplane stall with no activation of the stall warning system. PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 32103 Our investigation concluded that these aircraft, even if equipped with pneumatic deicing boots, are not approved for flight into known icing and will accrete critical amounts of ice on the protected and unprotected areas. Additionally, data suggest potentially large increases in stall speeds with no stall warning. The differences in the icing protection systems for the aircraft identified in this proposed AD differ greatly from later models that were approved for icing conditions. Some of these differences could include electric windshield (instead of alcohol), de-ice propeller (some might have had boots without the de-ice propeller), de-ice boots on entire span of wing as well as a different style de-ice boots, different pitot probe and static ports, and some models also added a de-ice boot to the vertical tail. These airplanes’ certification basis did not include Amendment 7 of CAR 3 Dated May 15, 1956, which required an applicant to provide to the pilot the types of operations and meteorological conditions (e.g. icing conditions) to which the operation of the airplane is limited by the equipment installed (CAR 3 § 3.772). Therefore, the pilot may not realize that, even with de-ice boots or other similar equipment installed, the airplane is not certificated for flight into known icing conditions. To address this condition and based on the accident history, there is a need to add a limitation to prohibit flight into known icing conditions due to the limitations of the installed equipment. This condition, if not corrected, could result in unusual flight characteristics that could lead to loss of control after flight into known icing conditions or an inadvertent encounter with icing conditions. Based on the data, an example of the unusual flight characteristics seen in many of the accidents is high sink speeds that resulted in a hard landing. Relevant Service Information We reviewed Cessna Service Bulletin MEB97–4, dated March 24, 1997. The service information describes procedures for providing a placard to inform the pilot that flight in known icing conditions is prohibited with the aircraft identified in the service information. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. E:\FR\FM\03JNP1.SGM 03JNP1 32104 Federal Register / Vol. 76, No. 107 / Friday, June 3, 2011 / Proposed Rules Proposed AD Requirements This proposed AD would require you to install a placard that prohibits flight into known icing conditions and install a placard that increases published speed on approach 17 mph (15 knots) in case of an inadvertent encounter with icing. Differences Between the Proposed AD and the Service Information The service information provides instructions on obtaining a placard from Cessna that prohibits flight into known icing conditions and that the airplane owner or a service facility may install the placard. This proposed AD requires fabrication and installation of an additional placard that increases the published speed on approach 17 mph (15 knots). This proposed AD also requires that a properly certificated aircraft mechanic must fabricate the additional placard and install both of these placards. The airplane owner or pilot is not allowed to fabricate and install the placards unless they are also a properly certificated aircraft mechanic. Costs of Compliance We estimate that this proposed AD affects 6,883 airplanes of U.S registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Fabricate and install placards ................... 1 work-hour × $85 per hour = $85 ........... $1 $86 $591,938 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. wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1 Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD would require you to install a 
placard that prohibits flight into known icing conditions and install a 
placard that increases published speed on approach 17 mph (15 knots) in 
case of an inadvertent encounter with icing. This proposed AD was 
prompted by an investigation of recent and historical icing-related 
accidents and incidents for the products listed above. We are proposing 
this AD to prohibit flight into known icing conditions as well as 
increase the approach speed in case of an inadvertent encounter with 
icing. This condition, if not corrected, could result in unusual flight 
characteristics that could lead to loss of control after flight into 
known icing conditions or an inadvertent encounter with icing 
conditions. Based on the data, an example of the unusual flight 
characteristics seen in many of the accidents is high sink speeds that 
resulted in a hard landing.

DATES: We must receive comments on this proposed AD by July 18, 2011.

Discussion

    We are proposing this AD as a result of an investigation of 51 
recent and historical icing-related accidents and incidents over the 
last 30 years that resulted in 36 fatalities for aircraft listed in 
Cessna Aircraft Company (Cessna) Service Bulletin MEB97-4. The non-
fatal events usually resulted in injuries and substantial aircraft 
damage. The National Transportation Safety Board dockets showed for two 
non-fatal landing events airplane stall with no activation of the stall 
warning system.
    Our investigation concluded that these aircraft, even if equipped 
with pneumatic deicing boots, are not approved for flight into known 
icing and will accrete critical amounts of ice on the protected and 
unprotected areas. Additionally, data suggest potentially large 
increases in stall speeds with no stall warning.
    The differences in the icing protection systems for the aircraft 
identified in this proposed AD differ greatly from later models that 
were approved for icing conditions. Some of these differences could 
include electric windshield (instead of alcohol), de-ice propeller 
(some might have had boots without the de-ice propeller), de-ice boots 
on entire span of wing as well as a different style de-ice boots, 
different pitot probe and static ports, and some models also added a 
de-ice boot to the vertical tail.
    These airplanes' certification basis did not include Amendment 7 of 
CAR 3 Dated May 15, 1956, which required an applicant to provide to the 
pilot the types of operations and meteorological conditions (e.g. icing 
conditions) to which the operation of the airplane is limited by the 
equipment installed (CAR 3 Sec.  3.772). Therefore, the pilot may not 
realize that, even with de-ice boots or other similar equipment 
installed, the airplane is not certificated for flight into known icing 
conditions. To address this condition and based on the accident 
history, there is a need to add a limitation to prohibit flight into 
known icing conditions due to the limitations of the installed 
equipment.
    This condition, if not corrected, could result in unusual flight 
characteristics that could lead to loss of control after flight into 
known icing conditions or an inadvertent encounter with icing 
conditions. Based on the data, an example of the unusual flight 
characteristics seen in many of the accidents is high sink speeds that 
resulted in a hard landing.

Relevant Service Information

    We reviewed Cessna Service Bulletin MEB97-4, dated March 24, 1997. 
The service information describes procedures for providing a placard to 
inform the pilot that flight in known icing conditions is prohibited 
with the aircraft identified in the service information.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

[[Page 32104]]

Proposed AD Requirements

    This proposed AD would require you to install a placard that 
prohibits flight into known icing conditions and install a placard that 
increases published speed on approach 17 mph (15 knots) in case of an 
inadvertent encounter with icing.

Differences Between the Proposed AD and the Service Information

    The service information provides instructions on obtaining a 
placard from Cessna that prohibits flight into known icing conditions 
and that the airplane owner or a service facility may install the 
placard. This proposed AD requires fabrication and installation of an 
additional placard that increases the published speed on approach 17 
mph (15 knots). This proposed AD also requires that a properly 
certificated aircraft mechanic must fabricate the additional placard 
and install both of these placards. The airplane owner or pilot is not 
allowed to fabricate and install the placards unless they are also a 
properly certificated aircraft mechanic.

Costs of Compliance

    We estimate that this proposed AD affects 6,883 airplanes of U.S 
registry.
    We estimate the following costs to comply with this proposed AD:

                                    per hour = $85.
----------------------------------------------------------------------------------------------------------------

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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
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),
    (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.

401, 402, 411, 414, and 421 airplanes identified in Cessna Aircraft 
Company Service Bulletin MEB97-4, dated March 24, 1997, certificated 
in any category.

Subject

    (d) Joint Aircraft System Component (JASC)/Air Transport 
Association (ATA) of America Code: 11, Placards and Markings.

Unsafe Condition

    (e) This AD was prompted by an investigation of recent and 
historical icing-related accidents and incidents for the products 
listed above. We are issuing this AD to prohibit flight into known 
icing conditions as well as increase the approach speed in case of 
an inadvertent encounter with icing. This condition, if not 
corrected, could result in unusual flight characteristics that could 
lead to loss of control after flight into known icing conditions or 
an inadvertent encounter with icing conditions. Based on the data, 
an example of the unusual flight characteristics seen in many of the 
accidents is high sink speeds that resulted in a hard landing.

Compliance

    (f) Comply with this AD within the compliance times specified, 
unless already done.
