14 CFR Part 39

[Docket No. FAA-2014-0187; Directorate Identifier 2012-NM-087-AD; 
Amendment 39-17917; AD 2014-15-15]
RIN 2120-AA64


Airworthiness Directives; Beechcraft Corporation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Beechcraft Corporation (Type Certificate Previously Held by Hawker 
Beechcraft Corporation; Raytheon Aircraft Company; Mitsubishi Heavy 
Industries, Inc. Ltd.) Model MU-300 airplanes, and Beechcraft 
Corporation (Type Certificate Previously Held by Hawker Beechcraft 
Corporation; Raytheon Aircraft Company; Beech Aircraft Corporation) 
Model 400, 400A, and 400T airplanes. This AD was prompted by multiple 
reports of fatigue cracking in the horizontal stabilizer ribs. This AD 
requires repetitive inspections of the horizontal stabilizer rib 
assemblies for cracking, and replacement if necessary. We are issuing 
this AD to detect and correct such cracking, which could result in the 
failure of the horizontal stabilizer and loss of pitch control of the 
airplane.

DATES: This AD is effective September 5, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Beechcraft 
Corporation (Type Certificate Previously Held by Hawker Beechcraft 
Corporation; Raytheon Aircraft Company; Mitsubishi Heavy Industries, 
Inc. Ltd.) Model MU-300 airplanes Type Certificate previously held by 
Mitsubishi; Raytheon Aircraft Company) Model MU-300 airplanes, and 
Hawker Beechcraft Corporation (Type Certificate Previously Held by 
Hawker Beechcraft Corporation; Raytheon Aircraft Company; Beech 
Aircraft Corporation) Model 400, 400A, and 400T airplanes. The NPRM 
published in the Federal Register on April 4, 2014 (79 FR 18848). The 
NPRM was prompted by multiple reports of fatigue cracking in the 
horizontal stabilizer ribs. The NPRM proposed to require repetitive 
inspections of the horizontal stabilizer rib assemblies for cracking, 
and replacement if necessary. We are issuing this AD to detect and 
correct such cracking, which could result in the failure of the 
horizontal stabilizer and loss of pitch control of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 18848, April 4, 
2014) 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 this 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 (79 FR 18848, April 4, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 18848, April 4, 2014).

Costs of Compliance

    We estimate that this AD affects 735 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.

 (d) Subject

    Air Transport Association (ATA) of America Code 55, Stabilizers.

(e) Unsafe Condition

    This AD was prompted by multiple reports of fatigue cracking in 
the horizontal stabilizer ribs. We are issuing this AD to detect and 
correct such cracking, which could result in the failure of the 
horizontal stabilizer and loss of pitch control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

 (g) Repetitive Inspections

    Before the accumulation of 7,400 total flight hours or within 6 
months after the effective date of this AD, whichever occurs later, 
perform a radiographic (x-ray) inspection or a borescope inspection 
for cracking of the horizontal stabilizer rib assemblies, in 
accordance with a method approved by the Manager, Wichita Aircraft 
Certification Office (ACO), FAA. Repeat the inspection thereafter at 
intervals not to exceed 2,400 flight hours. For an inspection

[[Page 44679]]

method to be approved by the Manager, Wichita ACO, as required by 
this paragraph, the Manager's approval letter must specifically 
refer to this AD.

(h) Replacement

    If any cracking is found during any inspection required by 
paragraph (g) of this AD: Before further flight, replace the 
horizontal rib assemblies with new horizontal rib assemblies, in 
accordance with a method approved by the Manager, Wichita ACO. For a 
replacement method to be approved by the Manager, Wichita ACO, as 
required by this paragraph, the Manager's approval letter must 
specifically refer to this AD. This replacement does not terminate 
the repetitive inspection requirements of paragraph (g) of this AD.

(i) Special Flight Permit

    Special flight permits may be issued in accordance with sections 
21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 
and 21.199) to operate the airplane to a location where the airplane

send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the ACO, send it to the attention of the 
person identified in paragraph (k) of this AD.
