Airworthiness Directives; Cessna

Type Certificate (STC) SA01303WI 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD would require installing a full 

authority digital engine control (FADEC) 

backup battery, replacing the 

supplement pilot’s operating handbook 

and FAA approved airplane flight 

manual, and replacing the FADEC 

backup battery every 12 calendar 

months. This proposed AD was 

prompted by an incident where an 

airplane experienced an in-flight engine 

shutdown caused by a momentary loss 

of electrical power to the FADEC. We 

are proposing this AD to prevent 

interruption of electrical power to the 

FADEC, which could result in an 

uncommanded engine shutdown. This 

failure could lead to a loss of engine 

power. 

DATES: We must receive comments on 

this proposed AD by January 31, 2011. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251.

Transportation, Docket Operations, M–

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2010–1243; Directorate Identifier 2010– 

CE–058–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

In 2007, a Diamond DA42 airplane 

experienced a dual in-flight engine 

shutdown. Our review of the incident 

determined the root cause was an unsafe 

design feature that allowed momentary 

interruption of electrical power to both 

engine FADECs. The interruption 

caused the FADECs to reset, shutting 

down both engines with a consequent 

loss of engine power. Cessna Model 172 

airplanes modified by STC No. 

SA01303WI have a similar unsafe 

design feature that can allow the FADEC 

to shut down or reset if the main battery 

is depleted and the electrical charging 

system malfunctions. 

This condition, if not corrected, could 

result in an uncommanded engine 

shutdown. This failure could lead to a 

loss of engine power. 

Relevant Service Information 

We reviewed Thielert Aircraft Engines 

GmbH Service Bulletins TM TAE 601– 

0007, Revision 8, dated October 14, 

2010, and TM TAE 601–1001 P1, 

Revision 8, dated October 14, 2010. The 

service information describes 

procedures for installation of a FADEC 

backup battery. 

FAA’s Determination 

We are proposing 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. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 14 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD:

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 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under the 

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.
