Airworthiness Directives; Hawker 

Beechcraft Corporation Model G58 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation Model 

G58 airplanes. This AD requires 

inspecting the installation of stand-off 

hardware between the heater fuel line 

and the heater over-temperature sensor 

wires and also brake reservoir tubing 

and the heater fuel pump wiring for 

minimum clearance and installing 

acceptable stand-off hardware if standoff hardware is missing or inadequate. 

This AD results from reports received of 

a power wire shorting out on the brake 

reservoir tube. We are issuing this AD 

to detect and correct inadequate 

clearance of the brake reservoir tubing 

and the heater fuel pump wiring, which 

could result in chafing and shorting out 

of the electrical wiring and chafing of 

the tubing carrying flammable fluids. 

This condition could lead to a fire in the 

nose wheel well. 

DATES: This AD becomes effective on 

April 15, 2010. 

On April 15, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

On December 8, 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 Hawker Beechcraft Corporation 

Model G58 airplanes. This proposal was 

published in the Federal Register as a 

notice of proposed rulemaking (NPRM) 

on December 17, 2009 (74 FR 66930). 

The NPRM proposed to require 

inspecting the installation of stand-off 

hardware between the heater fuel line 

and the heater over-temperature sensor 

wires and also brake reservoir tubing 

and the heater fuel pump wiring for 

minimum clearance and installing 

acceptable stand-off hardware if standoff hardware is missing or inadequate. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. The following presents the 

comments received on the proposal and 

FAA’s response to each comment: 

Comment Issue No. 1: Effective Date 

Mr. Busby states we should make the 

effective date of the AD immediate. 

The FAA disagrees. We carefully 

reviewed the data for this safety concern 

to assess the risk level of this particular 

event. After reviewing the data, we 

compared this safety concern with 

similar safety concerns in the past. 

Then, we assigned a level of risk for this 

particular event equivalent to the level 

of risk assigned to the similar past safety 

concerns we used for comparison. With 

the information we have at this time, we 

set the time frame to comply with the 

actions for this AD similar to the time 

frame that was set for similar safety 

concerns that had equivalent risk levels. 

Without additional information to 

increase the risk level of this safety 

concern we have determined that the 

time frame set for complying with this 

safety concern is in line with past 

precedent. 

We are not changing the final rule AD 

action based on this comment. 

Comment Issue No. 2: Work-Hours 

Mr. Busby states that the work-hours 

allotted to do the proposed inspection 

are not enough. We infer the commenter 

wants us to increase the work-hours to 

do the proposed inspection to relieve 

the pressure on mechanics. 

The FAA disagrees. For this AD, we 

derived the work-hours from the 

Hawker Beechcraft Corporation service 

information. Those work-hours were 

used to calculate the estimated cost 

impact on the owners/operators of the 

affected airplanes. The FAA uses that 

cost estimate in the economic analysis 

to determine if the AD will have a 

substantial impact on small entities. In 

general, the direct cost to an operator is 

the most significant economic 

consideration of an AD. Since the workhours in the AD are estimates for 

determining cost impact to the operator, 

maintenance personnel may take more 

or less time to do the inspection and/or 

maintenance as is necessary for that 

particular aircraft or task. Moderately 

increasing the estimated work-hours for 

the initial inspection does not 

significantly increase the cost impact on 

the operator. 

We are not changing the final rule AD 

action based on this comment. 

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 71 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the inspection of the heater fuel line, the 

heater over-temperature sensor wires, 

the brake reservoir line, and the fuel 

heater power wire:

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–2009–1176; 

Directorate Identifier 2009–CE–062–AD’’ 

in your request.

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) 

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: 

One A300–600 aeroplane operator reported 

that, during a routine inspection, the Right 

Hand frame 40 forward fitting between 

stringer 32 and stringer 33 was found 

cracked. The subject aeroplane had 

previously been modified in accordance with 

Airbus SB A300–57–6053 (Airbus 

Modification 10453). 

This condition, if not corrected, could 

result in a deterioration of the structural 

integrity of the frame. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective April 

15, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 15, 2010.
