AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

PIAGGIO AERO INDUSTRIES S.p.A. 

Model P–180 airplanes. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as jamming of the external 

bearing of the screwjack drive gear, 

which resulted in failure of the main 

wing outboard flap external actuator. 

We are issuing this proposed AD to 

require actions to address the unsafe 

condition on these products. 

DATES: We must receive comments on 

this proposed AD by July 30, 2012. 

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.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No.: 

2012–0066, dated April 24, 2012 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

Failures of the Main Wing Outboard Flap 

external actuator have been reported by P.180 

operators. 

The investigation revealed that due to 

jamming of the external bearing, the 

screwjack drive gear disengaged from its seat 

and the external actuator stopped, while the 

inner one continued its run. 

This condition, if not corrected, could lead 

to an asymmetrical flap actuators operation 

and cause an interference between the flap 

and adjacent aileron, possibly resulting in 

reduced control of the aeroplane. 

For the reasons described above, this AD 

requires the installation of a covering cage on 

the screwjack, as a temporary corrective 

action, which does not allow the 

disengagement of the affected gear. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

PIAGGIO AERO INDUSTRIES S.p.A. 

has issued Service Bulletin No. 80– 

0318, dated October 24, 2011; Service 

Bulletin No. 80–0318, revision 1, dated 

February 3, 2012; and Service Bulletin 

No. 80–0318, revision 2, dated March 

28, 2012. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design.

Federal Register / Vol. 77, No. 116 / Friday, June 15, 2012 / Proposed Rules 35889 

Costs of Compliance 

We estimate that this proposed AD 

will affect 110 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $2,770 per 

product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $360,800, or $3,280 per 

product. 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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.

ACTION: Notice of proposed rulemaking

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Diamond Aircraft Industries GmbH 

Models DA 42, DA 42 NG, and DA 42 

M–NG airplanes. This proposed AD 

results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as excessive voids in the 

adhesive joint between the center wing 

spars and the upper center wing skins. 

This condition could cause the wing to 

fail, which could result in loss of 

control of the airplane. We are issuing 

this proposed AD to require actions to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by July 30, 2012.
