**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 Multiengine 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


### 19018 Federal Register / Vol. 80, No. 68 / Thursday, April 9, 2015 / Rules and Regulations

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:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Prepare airplane for inspections ........... 3 work-hours × $85 per hour = $255 per inspection cycle. Not applicable ....... $255 per inspection cycle. $141,525 per inspection cycle X-ray inspection of the engine mount

beams (4 engine mount beams per airplane). 8 work-hours × $85 per hour = $680 per inspection cycle. $180 ...................... $860 per inspection cycle. $477,300 per inspection cycle

Eddy current inspection of the engine

mount beams (4 engine mount beams per airplane). 1 work-hour × $85 per hour = $85 per inspection cycle. Not applicable ....... $85 per inspection cycle. $47,175 per inspection cycle

Visual inspection of the engine mount

beams (4 engine mount beams per airplane). 1 work-hour × $85 per hour = $85 per inspection cycle. Not applicable ....... $85 per inspection cycle. $47,175 per 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. List of Subjects in 14 CFR Part 39
