14 CFR Part 39

[Docket No. FAA-2014-0701; Directorate Identifier 2014-CE-025-AD; 
Amendment 39-18034; AD 2014-24-01]

Airworthiness Directives; Various de Havilland Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Harry E. Williams de Havilland Model DH 82A airplanes, all Cliff 
Robertson de Havilland Model DH 82A airplanes, and all de Havilland 
Model DH 83 airplanes. This AD was prompted by reports of structural 
failure of the attachment of the wing to the fuselage that resulted 
from failed lateral fuselage tie rods. This AD requires inspecting the 
aircraft maintenance records to determine the date of installation or 
the date of last replacement of the lateral fuselage tie rods. This AD 
also requires repetitively replacing all lateral fuselage tie rods and 
attaching nuts at a specified life limit interval. We are issuing this 
AD to correct the unsafe condition on these products.

DATES: This AD is effective January 6, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 6, 
2015.

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 all Harry E. Williams de 
Havilland Model DH 82A airplanes, all Cliff Robertson de Havilland 
Model DH 82A airplanes, and all de Havilland

[[Page 71303]]

Model DH 83 airplanes. The NPRM published in the Federal Register on 
September 15, 2014 (79 FR 54919). The NPRM was prompted by reports of 
structural failure of the attachment of the wing to the fuselage that 
resulted from failed lateral fuselage tie rods. The NPRM proposed to 
require inspecting the aircraft maintenance records to determine the 
date of installation or the date of last replacement of the lateral 
fuselage tie rods. The NPRM also proposed to require repetitively 
replacing all lateral fuselage tie rods and attaching nuts at a 
specified life limit interval. We are issuing this AD to correct the 
unsafe condition on these products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 54919, September 
15, 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 54919, September 15, 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 54919, September 15, 2014).

Costs of Compliance

    We estimate that this AD will affect 69 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.
