14 CFR Part 39

[Docket No. FAA-2011-1161; Directorate Identifier 2011-CE-036-AD; 
Amendment 39-16850; AD 2011-21-51]

Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cessna Aircraft Company (Cessna) Model 525C airplanes. This emergency 
AD was sent previously to all known U.S. owners and operators of these 
airplanes. This AD requires replacing certain lithium-ion batteries 
installed as the main aircraft battery with either a Ni-Cad or a lead 
acid battery. This AD was prompted by a report of a battery fire that 
resulted after an energized ground power unit was connected to one of 
the affected airplanes equipped with a lithium-ion battery as the main 
aircraft battery. We are issuing this AD to correct the unsafe 
condition on these products.

DATES: This AD is effective November 1, 2011 to all persons except 
those persons to whom it was made immediately effective by Emergency AD 
2011-21-51, issued on October 6, 2011, which contained the requirements 
of this amendment.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication identified in the AD as of November 
1, 2011.
    We must receive comments on this AD by December 16, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    On October 6, 2011, we issued Emergency AD 2011-21-51, which 
requires replacing the lithium-ion main aircraft battery, Cessna part 
number (P/N) 9914788-1, with a Ni-Cad or a lead acid battery. This 
emergency AD was sent previously to all known U.S. owners and operators 
of these airplanes. This action was prompted by a report of a battery 
fire that resulted after an energized ground power unit was connected 
to a Cessna Model 525C airplane equipped with a lithium-ion battery, 
Cessna P/N 9914788-1, as the main aircraft battery. This condition, if 
not corrected, could result in an aircraft fire.

Relevant Service Information

    We reviewed Cessna Citation Service Bulletin SB525C-24-05, dated 
September 29, 2011. The service information describes procedures for 
replacing lithium-ion main aircraft batteries, Cessna P/N 9914788-1, 
with Ni-Cad or lead acid batteries.

FAA's Determination

    We are issuing 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 the same type design.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of a 
battery fire that resulted after an energized ground power unit was 
connected to one of the affected airplanes equipped with a certain 
lithium-ion battery as the main aircraft battery. If not corrected, 
this condition could lead to an aircraft fire. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. 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 the docket number FAA-2011-1161 and 
Directorate Identifier 2011-CE-036-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.

Costs of Compliance

    We estimate that this AD affects 43 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                   Labor cost          Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Replace the lithium-ion main      2.5 work-hours x    From $4,314 to      From $4,526.50 to   From $194,639.50
 aircraft battery with a Ni-Cad    $85 per hour =      $7,076.             $7,288.50.          to $313,405.50.
 or a lead acid battery.           $212.50.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
