400T Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 400A, and 400T airplanes. This 

proposed AD would require a detailed 

inspection for proper sealant of the left 

and right pylon firewall structures, and 

corrective actions if necessary. This 

proposed AD results from reports of 

missing sealant on the left and right 

pylon firewall structures. We are 

proposing this AD to detect and correct 

missing sealant on the left and right 

pylon firewall structures, which, in the 

event of an engine fire, could result in 

flames penetrating the seams in the 

firewall between the engine and the aft 

fuselage, and a subsequent uncontrolled 

fire in the aft fuselage. 

DATES: We must receive comments on 

this proposed AD by November 15, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2010–0954; Directorate Identifier 

2010–NM–078–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received reports of missing 

sealant on the left and right pylon 

firewall structures. The sealant may not 

have been applied on the firewall at the 

seams in production. Pylon firewall 

structures that do not have this sealant 

do not meet the applicable design 

intent. In the event of an engine fire, 

flames could penetrate the seams in the 

firewall between the engine and the aft 

fuselage. Missing or inadequate sealant, 

if not corrected, combined with the 

event of an engine fire could result in 

an uncontrolled fire in the aft fuselage. 

Relevant Service Information 

We have reviewed Hawker Beechcraft 

Mandatory Service Bulletin SB 54–3946, 

Revision 2, dated February 2010. This 

service bulletin describes procedures for 

doing an inspection of the left and right 

pylon for coverage of firewall sealant on 

the seams, and corrective actions. While 

Hawker Beechcraft Mandatory Service 

Bulletin SB 54–3946, Revision 1, dated 

May 2009, provides the procedures for 

doing the inspection of the left and right 

pylon for coverage of firewall sealant on 

the seams and applying sealant, it does 

not specify the dimensions of the 

sealant. Corrective actions include 

cleaning, sealing, or recoating affected 

areas; and recoating sealant. Figure 4 of 

Hawker Beechcraft Mandatory Service 

Bulletin SB 54–3946, Revision 2, dated 

February 2010, contains the 

specifications of the sealant depth. 

FAA’s Determination and Requirements 

of This Proposed AD 

We are proposing this AD because we 

evaluated all relevant information and 

determined the unsafe condition 

described previously is likely to exist or 

develop in other products of these same 

type designs. This proposed AD would 

require accomplishing the actions 

specified in the service information 

described previously, except as 

discussed under ‘‘Differences Between 

the Proposed AD and Service 

Information.’’ 

Differences Between the Proposed AD 

and Service Information 

Hawker Beechcraft Mandatory Service 

Bulletin SB 54–3946, Revision 2, dated 

February 2010, specifies a compliance 

time of the next scheduled inspection, 

but no later than 12 months after the 

date of the service bulletin revision. 

This proposed AD would require a 

compliance time of within 200 flight 

hours or within 12 months after the 

effective date of this AD, whichever 

occurs first. The service bulletin also 

does not specify what type of inspection 

to perform. This AD requires that a 

detailed inspection be performed. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 165 airplanes of U.S. 

registry. We also estimate that it would 

take about 1 work-hour per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this proposed AD to the U.S. 

operators to be $14,025, or $85 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 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), 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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.
