SUPPLEMENTARY INFORMATION:

Discussion

    We received reports of cracks found on the engine mount beams of 
certain Cessna Aircraft Company (Cessna) Model 402C airplanes. The 
cracks found run across the beam and extend beyond the doubler located 
under the aft engine mount and aft of the forward engine mount. 
Investigation revealed that the cause of the cracks is fatigue.
    The engine beam mounts of the Cessna Model 402C airplanes are the 
same type design as that of the Cessna Model 414A airplanes.
    This condition, if not detected and corrected, could result in 
failure of an engine mount beam and could lead to engine separation 
with consequent loss of power and loss of control. We are issuing this 
AD to correct the unsafe condition on these products.

Relevant Service Information Under 1 CFR Part 51

    We reviewed Cessna Aircraft Company Multi-engine Service Letter No. 
MEL-54-01, dated March 20, 2015, including the undated Attachment, 
``Inspection Results Form.'' The Cessna Aircraft Company Multi-engine 
Service Letter describes procedures for inspecting the engine mount 
beams for cracks and reporting the inspection results to Cessna. This 
information is reasonably available at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2015-0839, or you may see 
ADDRESSES for other ways to access this service information.

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 repetitively inspecting the engine mount beams for 
cracks and contacting Cessna for an FAA-approved corrective action if 
cracks are found. This AD also requires sending the inspection results 
to the FAA and to Cessna.

Differences Between This AD and the Service Information

    Cessna Aircraft Company Multi-engine Service Letter No. MEL-54-01, 
dated March 20, 2015, including the undated Attachment, ``Inspection 
Results Form,'' specifies reporting the inspection results to Cessna. 
In this AD, we also require that the inspection results be reported to 
the FAA.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this

[[Page 19018]]

AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
cracks in the engine mount beam could cause the engine mount beam to 
fail and lead to engine separation with consequent loss of power and 
loss of control. 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-2015-0839 and 
Directorate Identifier 2015-CE-006-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 555 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

 beams per airplane).             inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We have no way of knowing the extent of cracks that may be found 
during the required inspections. Therefore, we have no way of 
determining the cost of the corrective action.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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.
