14 CFR Part 39

[Docket No. FAA-2010-0954; Directorate Identifier 2010-NM-078-AD; 
Amendment 39-16596; AD 2011-03-12]
RIN 2120-AA64


Airworthiness Directives; Hawker Beechcraft Corporation (Type 
Certificate Previously Held by Raytheon Aircraft Company; Beech 
Aircraft Corporation) Model 400A and 400T Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires a detailed inspection for 
proper sealant of the left and right pylon firewall structures, and 
corrective actions if necessary. This AD results from reports of 
missing sealant on the left and right pylon firewall structures. We are 
issuing 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: This AD is effective March 14, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 14, 
2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM was published in the Federal Register 
on October 1, 2010 (75 FR 60669). That NPRM proposed to require a 
detailed inspection for proper sealant of the left and right pylon 
firewall structures, and corrective actions if necessary.

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 relevant data and determined that air safety and 
the public interest require adopting the AD as proposed--except for 
minor editorial changes. We have determined that these minor changes:
     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 165 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

    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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

Inspection and Corrective Action

    (g) Within 200 flight hours or 12 months after the effective 
date of this AD, whichever occurs first: Do a detailed inspection 
for appropriate coverage of firewall sealant of the left and right 
pylon firewall structure, as specified in the figures of Hawker 
Beechcraft Mandatory Service Bulletin SB 54-3946, Revision 2, dated 
February 2010, and all applicable corrective actions; in accordance 
with the Accomplishment Instructions of Hawker Beechcraft Mandatory 
Service Bulletin SB 54-3946, Revision 2, dated February 2010. Do all 
applicable corrective actions before further flight.

    Note 1:  For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. Send information to
