Airworthiness Directivesj Continental Motors, Inc. Reciprocating Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice ofproposedrulernaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Continental Motors, Inc. (CMI) TSI0-550-K, TSIOF-550-K, TSI0-550-C, TSIOF-550-D, and 

### TSI0-550-N reciprocating engines. This proposedAD was prompted by a report ofan llllcommanded in-flight shutdown (IFSD) resulting in injuries and significant airplane damage. This proposed AD would require replacing the oil cooler

cross fitting assembly. We are proposingthis AD to prevent failure ofthe oil cooler cross fitting and engine, IFSD and loss ofthe airplane. 

### DATES: We must receive comments onthis proposed AD by [INSERT DATE 60 DAYS AFTERDATE OF PUBLICATION IN THE Federal Register]. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any ofthe following methods:

SUPPLEMENTARY INFORMATION: 

### Comments Invited We invite you to send any written relevant data, views, or arguments about this NPRM. Sendyour comments to an address listed under the ADDRESSES section. Include "DocketNo. FAA-2016-0069; Directorate Identifier 2016-NE-01-AD" atthe beginning ofyour comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects ofthis NPRM. We will consider all

We will post all comments we receive, without change, to http://www.regulations.gov, including anypersonal informationyouprovide. We will also posta report summarizing each substantive verbal contactwe receive about this NPRM. 

### Discussion A Cirrus SR-22T crashed on November 3, 2015 due to an uncommanded IFSD. The crashcaused four minorpersonal injuries and substantial airplane damage. The root

cause ofthe engine IFSD wasthe loss ofengine oil throughthe fatigue-induced fracture ofan oil cooler cross fitting nipple. This condition, ifnot corrected, could result in failure ofthe oil cooler cross fitting and engine, IFSD, and loss ofthe airplane. 

### Relevant Service Information under 1 CFRPart 51 We reviewed CMI Critical Service Bulletin (CSB) No. CSB15-2C, dated November 9, 2015 and CMI CSB No. CSB15-7A, datedNovember 10,2015. The CSBs describe detailedprocedures for replacing oil cooler cross fittings, nipples, andbushings with a redesigned oil cooler cross fitting. This service information is reasonably available because the interestedparties have access to it through their normal course ofbusiness· or bythe means identified inthe ADDRESSES section ofthis docmnent. 

### FAA's Determination We are proposing this NPRM because we evaluated all the relevant information and detenninedtheunsafe condition described previously is likely to exist or develop in otherproducts ofthe same type design.

### Proposed AD Requirements This NPRM wouldrequire accomplishing the actions specified inthe service information described previously, except as discussed under "Differences Betweenthis Proposed AD and the Service Information." 

### Differences Between this Proposed AD and the Service Information CMI CSB No. CSB15-7A, datedNovember 10, 2015 requires replacing the oil cooler cross fitting, nipple, and bushing prior to further flight. CMI CSB No. CSB15-2C, dated November 9, 2015 requires replacing the oil cooler cross fitting, nipple, and bushing within25 hours ofengine operation or at the next scheduled inspection or engine service, whichever occurs first. This proposed AD requires replacing the fitting atthe next engine maintenance eventnot to exceed 12 months or I00 flight hours after the effective date ofthis AD, whichever occurs first. 

### Costs ofCompliance We estimatethatthis proposed AD affects 1,307 engines installed on airplanes of U.S. registry. We also estimate that it will take about 1 hour per engine to comply with this proposed AD. The average laborrate is $85 perhour. Parts would cost about $0 per engine. Based on these figures, we estimate the total cost ofthis proposed AD to U.S. operators to be $111,095. Our cost estimate is exclusive ofpossible warranty coverage. 

### Authority for this Rulemaking Title 49 ofthe United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority ofthe FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the .scope ofthe Agency's authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section44701: "General requirements." Underthat section, Congress charges the FAA with promoting safe flight ofcivil aircraft in air commerce by 4

### prescribing regulations for practices, methods, andproceduresthe Administrator finds necessary for safety in air commerce. This regulation is within the scope ofthat 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 thatthis proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would nothave a substantial direct effect onthe States, onthe relationship betweenthe national Government and the States,

or onthe distribution ofpower and responsibilities among the various levels of government. Forthe reasons discussed above, I certifythis proposedregulation: (1) 

### Is not a "significantregulatory action" underExecutive Order 12866, (2) Is not a "significantrule" under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and ( 4) Will nothave a significant economic impact, positive or negative, on a substantial number ofsmall entities under the criteria ofthe Regulatory Flexibility Act. List ofSubjects in 14 CFRPart 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFRpart 39 as follows: PART 39 

### -AIRWORTHINESS DIRECTIVES I. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113,44701.
