Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2013-0753; Directorate Identifier 2013-CE-025-AD]
RIN 2120-AA64

Airworthiness Directives; Beechcraft Corporation 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 Beechcraft Corporation (type certificate previously held by 
Hawker Beechcraft Corporation) Models 1900, 1900C, and 1900D airplanes. 
This proposed AD was prompted by reports of cracking in the front spar 
cap angles and hat section structure of the vertical stabilizer. This 
proposed AD would require inspections of the vertical stabilizer spar 
angles and hat section for cracks with corrective actions as necessary. 
We are proposing this AD to correct the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by October 11, 
2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2013-0753; 
Directorate Identifier 2013-CE-025-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 were notified by Beechcraft Corporation of cracks found in the 
vertical stabilizer structure of Models 1900, 1900C, and 1900D 
airplanes. Out of 140 airplanes inspected, 56 cracks have been found. 
This condition, if not corrected, could lead to structural failure of 
the vertical stabilizer and result in loss of control.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 55-
4114, dated August 2012; Hawker Beechcraft Corporation Model 1900/1900C 
Airliner Structural Inspection Manual, Part Number 98-30937G2, dated 
May 1, 2013; and Beechcraft Corporation Model 1900D Airliner Structural 
Inspection Manual, Part Number 129-590000-65E5, dated May 1, 2013. The 
service information describes procedures for visually inspecting the 
vertical stabilizer spar angles and hat section.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require doing visual inspections of the 
vertical stabilizer spar angles and hat section for cracks and taking 
corrective actions as necessary.

Costs of Compliance

    We estimate that this proposed AD affects 400 airplanes.
    We estimate the following costs to comply with this proposed AD:

 section.

    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 aircraft that might need these 
repairs:

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),
    (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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

depending on the cracking found. You must contact Beechcraft 
Corporation and provide them with crack detail information for them 
to determine residual strength of the airplane before applying to 
the FAA for a special flight permit. You can find contact 
information for Beechcraft Corporation in paragraph (k)(1) of this 
AD.

 (j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita ACO, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as
