AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Piper Aircraft, Inc. Models PA–46–350P 

and PA–46R–350T airplanes. This AD 

requires you to inspect the 35-amp and 

250-amp current limiters to verify they 

are installed in the proper locations and 

correct the installation if the current 

limiters are not installed in the proper 

locations. This AD also limits operation 

to ‘‘only under day visual flight rules 

(VFR)’’ until the current limiter 

installation is inspected and corrected. 

This AD results from three reports of 

incorrectly installed current limiters. 

We are issuing this AD to detect and 

correct incorrect installation of 35-amp 

and 250-amp current limiters, which 

could result in failure of the 35-amp 

current limiter if installed in the 250- 

amp location. This failure could lead to 

a total loss of electrical power. 

DATES: This AD becomes effective on 

May 5, 2009. 

On May 5, 2009, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

On January 7, 2009, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to 

certain Piper Aircraft, Inc. Models PA– 

46–350P and PA–46R–350T airplanes. 

This proposal was published in the 

Federal Register as a notice of proposed 

rulemaking (NPRM) on January 15, 2009 

(74 FR 2425). The NPRM proposed to 

require an inspection to verify the 35- 

amp and 250-amp current limiters are 

installed in the proper locations and 

correct the installation if the current 

limiters are not installed in the proper 

locations. The NPRM also proposed to 

limit operation to only under day VFR 

until the current limiter installation is 

inspected and corrected.

14462 Federal Register / Vol. 74, No. 60 / Tuesday, March 31, 2009 / Rules and Regulations 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. We received no comments on 

the proposal or on the determination of 

the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed except for 

minor editorial corrections. We have 

determined that these minor 

corrections: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD affects 118 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the inspection: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on 

U.S. operators 

1 work-hour × $80 per hour = $80 ............................... Not Applicable .............................................................. $80 $9,440 

We estimate the following costs to do 

any necessary repairs that would be 

required based on the results of the 

proposed inspection. We have no way of 

determining the number of airplanes 

that may need this repair: 

Labor cost Parts cost Total cost per 

airplane 

1 work-hour × $80 per hour = $80 ............................................. Not Applicable ............................................................................ $80 

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 AD. 

Regulatory Findings 

We have 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 that this AD: 

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); 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 summary of the costs 

to comply with this AD (and other 

information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2009–0007; 

Directorate Identifier 2008–CE–072– 

AD’’ in your request.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

McDonnell Douglas Model 717–200 

airplanes. This AD requires modifying 

the wire installation of the auxiliary 

hydraulic pump in the right wheel well 

of the main landing gear (MLG). This 

AD results from fuel system reviews 

conducted by the manufacturer. We are 

issuing this AD to prevent a tire burst 

when the MLG is in the retracted 

position from causing damage to the 

wire assembly of the auxiliary hydraulic 

pump and subsequent electrical arcing, 

creating the potential of an ignition 

source to the center wing tank, which, 

in combination with flammable fuel 

vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 

DATES: This AD is effective May 5, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 5, 2009.
