ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

Due to a manufacturing error, some rivets, 

required by drawings, were not installed in 

the joints between two ceiling beams and the 

rear pressurized bulkhead. 

If left uncorrected, long term fatigue stress 

could locally weaken the structure, 

compromising the fuselage structural 

integrity. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

November 18, 2010. 

On November 18, 2010, the Director 

of the Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on July 23, 2010 (75 FR 43105). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Due to a manufacturing error, some rivets, 

required by drawings, were not installed in 

the joints between two ceiling beams and the 

rear pressurized bulkhead. 

If left uncorrected, long term fatigue stress 

could locally weaken the structure, 

compromising the fuselage structural 

integrity. 

This AD requires the accomplishment of 

Piaggio Aero Industries (PAI) Service 

Bulletin (SB) 80–0268 original issue, which 

contains instructions to rework the affected 

area, thus restoring the fuselage design 

strength as well as the fatigue specifications 

of the structure. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 


emcdonald on DSK2BSOYB1PROD with RULES
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations 63059 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 6 

products of U.S. registry. We also 

estimate that it will take about 30 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $100 per 

product. 

Based on these figures, we estimate 

the cost of this AD to the U.S. operators 

to be $15,900 or $2,650 per product. 

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 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 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); and 

(3) 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

Some cases of failure of engine oil 

dipsticks, installed on Pratt & Whitney

engines, were detected on P.180 aeroplanes; 

such failures, due to moisture penetration 

into the dipstick and subsequent corrosion, 

can cause incorrect reading of the engine oil

If left uncorrected, this situation 

could lead to in-flight engine failure(s). 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on July 23, 2010 (75 FR 43095). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Some cases of failure of engine oil

Canada (P&WC) PT6A66 and PT6A66B 

engines, were detected on P.180 aeroplanes; 

such failures, due to moisture penetration 

into the dipstick and subsequent corrosion, 

can cause incorrect reading of the engine oil 

low level on the Refuel/Ground Test Panel. 

If left uncorrected, this situation 

could lead to in-flight engine failure(s). 

This AD requires: 

(1) Repetitive visual checks of the 

engine oil levels to prevent an 

undetected low level condition; 

(2) Repetitive inspections of the oil 

dipsticks to detect faulty units; 

(3) Replacement of faulty oil dipsticks 

or visual checks of the oil level at 

reduced not to exceed intervals, until 

replacement of faulty units. 

The engine TC Holder is currently 

developing a modification that will 

address the unsafe condition identified 

in this AD; once such modification is 

developed, approved and available, 

further mandatory actions might be 

considered. 

This Correction is issued to amend 

the AD number heading: It was PAD, it 

is AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

99 products of U.S. registry. We also 

estimate that it will take about 2.5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD to the U.S. operators 

to be $21,038 or $212.50 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $9,000, for a cost of $9,085 per 

product. We have no way of 

determining the number of products 

that may need these actions.
