Airworthiness Directives; Piaggio Aero 

Industries S.p.A. Model P 180 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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 pressurization loads, the fuselage 

frame of the emergency exit door could suffer 

from fatigue and develop cracks in its 

corners. The superseded Italian 

Airworthiness Directive (AD) 1995–059 was 

issued to require modification of the 

emergency door frame in accordance with 

Piaggio (at the time I.A.M. Rinaldo Piaggio 

S.p.A.) Service Bulletin 80–0057 original 

issue. Parts necessary to carry out the 

modification were a new door pan assembly 

and a doubler; Since these parts are no longer 

available, Piaggio Aero Industries S.p.A. 

(PAI) designed new suitable part numbers 

introduced by Revision 1 of Service Bulletin 

80–0057. The present AD mandates 

modification of the fuselage emergency door 

frame in accordance with Revision 1 of 

Service Bulletin 80–0057 from PAI. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

March 11, 2008.

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 December 14, 2007 (72 FR 

71089). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Due to pressurization loads, the fuselage 

frame of the emergency exit door could suffer 

from fatigue and develop cracks in its 

corners. The superseded Italian 

Airworthiness Directive (AD) 1995–059 was 

issued to require modification of the 

emergency door frame in accordance with 

Piaggio (at the time I.A.M. Rinaldo Piaggio 

S.p.A.) Service Bulletin 80–0057 original 

issue. Parts necessary to carry out the 

modification were a new door pan assembly 

and a doubler; Since these parts are no longer 

available, Piaggio Aero Industries S.p.A. 

(PAI) designed new suitable part numbers 

introduced by Revision 1 of Service Bulletin 

80–0057. The present AD mandates 

modification of the fuselage emergency door 

frame in accordance with Revision 1 of 

Service Bulletin 80–0057 from PAI. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

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 

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 

31 products of U.S. registry. We also 

estimate that it will take about 70 workhours per product to comply with basic 

requirements of this AD. The average 

labor rate is $80 per work-hour. 

Required parts will cost about $14,105 

per product. 

Based on these figures, we estimate 

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

to be $610,855 or $19,705 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 


rmajette on PROD1PC64 with RULES
6602 Federal Register / Vol. 73, No. 24 / Tuesday, February 5, 2008 / Rules and Regulations 

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.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2008–03–14 Piaggio Aero Industries S.p.A.: 

Amendment 39–15365; Docket No. 

FAA–2007–0294; Directorate Identifier 

2007–CE–087–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 11, 2008. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to PIAGGIO P–180 

airplanes, manufacturer serial numbers 

(MSN) 1001, 1002, 1004, and MSN 1006 

through 1033, that: 

(1) are certificated in any category; and 

(2) have not been modified in accordance 

with Piaggio Aero Industries Service Bulletin 

No. 80–0057, dated February 7, 1995. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 53: Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Due to pressurization loads, the fuselage 

frame of the emergency exit door could suffer 

from fatigue and develop cracks in its 

corners. The superseded Italian 

Airworthiness Directive (AD) 1995–059 was 

issued to require modification of the 

emergency door frame in accordance with 

Piaggio (at the time I.A.M. Rinaldo Piaggio 

S.p.A.) Service Bulletin 80–0057 original 

issue. Parts necessary to carry out the 

modification were a new door pan assembly 

and a doubler; Since these parts are no longer 

available, Piaggio Aero Industries S.p.A. 

(PAI) designed new suitable part numbers 

introduced by Revision 1 of Service Bulletin 

80–0057. The present AD mandates 

modification of the fuselage emergency door 

frame in accordance with Revision 1 of 

Service Bulletin 80–0057 from PAI. 

The MCAI requires the modification of the 

fuselage frame of the emergency door, using 

the newly designed door pan assembly and 

doubler, following Piaggio Aero Industries 

S.p.A. SB 80–0057, Revision 1, dated May 31, 

2007. 

Actions and Compliance 

(f) Unless already done, replace the 

emergency exit door pan assembly part 

number (P/N) 80–111152–401 with a new 

door pan assembly P/N 80–111152–405, and 

a new doubler reinforcement P/N 80–

111604–001, following Piaggio Aero 

Industries S.p.A. Mandatory Service Bulletin 

N.: 80–0057, Revision 1, dated May 31, 2007, 

at whichever of the following occurs later: 

(1) When the airplane reaches 4,500 hours 

total time-in-service (TIS); or 

(2) Within 6 months after March 11, 2008 

(the effective date of this AD) or 500 hours 

TIS after March 11, 2008 (the effective date 

of this AD), whichever of these occurs first. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: No 

differences.
