Airworthiness Directives; Continental

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Continental Motors, Inc. (CMI) models 

TSIO–520, TSIO–550–K, TSIOF–550K, 

and IO–550–N series reciprocating 

engines. This emergency AD was sent 

previously to all known U.S. owners 

and operators of these engines. This AD 

requires replacing affected CMI starter 

adapters with starter adapters eligible 

for installation. This AD was prompted 

by 5 reports received of fractures in 

starter adapter shaft gears in certain part 

number (P/N) CMI starter adapters. We 

are issuing this AD to prevent failure of 

the starter adapter gear shaft, leading to 

an inoperable oil scavenge pump and 

engine in-flight shutdown. 

DATES: This AD is effective December 

28, 2011 to all persons except those 

persons to whom it was made 

immediately effective by Emergency AD 

2011–25–51, issued on November 29, 

2011, which contained the requirements 

of this amendment. 

We must receive comments on this 

AD by January 27, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

On November 29, 2011, we issued 

Emergency AD 2011–25–51, which 

requires replacing affected CMI starter 

adapters with starter adapters eligible 

for installation. This action was 

prompted by 5 reports received of 

fractures in starter adapter shaft gears in 

certain P/N CMI starter adapters. This 

condition, if not corrected, could result 

in failure of the starter adapter gear 

shaft, leading to an inoperable oil 

scavenge pump and engine in-flight 

shutdown. 

Relevant Service Information 

We reviewed CMI Mandatory Service 

Bulletin (MSB) No. MSB11–4, dated 

November 23, 2011. The MSB describes 

the affected starter adapters, and 

describes what starter adapters are 

eligible for installation. 

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 replacing affected 

CMI starter adapters with starter 

adapters eligible for installation. 

Differences Between the AD and the 

Service Information 

The CMI MSB No. MSB11–4, dated 

November 23, 2011 requires reporting. 

This emergency AD does not. 

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 the short compliance 

time required to remove the affected 

parts from service. 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–2011–1341 and Directorate 

Identifier 2011–NE–41–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.

Federal Register / Vol. 76, No. 239 / Tuesday, December 13, 2011 / Rules and Regulations 77383 

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 will affect 

195 engines installed on airplanes of 

U.S. registry. We also estimate that it 

will take about 4 work-hours per engine 

to perform the actions required by this 

AD, and that the average labor rate is 

$85 per work-hour. Required parts will 

cost about $500 per engine. Based on 

these figures, we estimate the total cost 

of the AD to U.S. operators to be 

$163,800. 

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.
