14 CFR Part 39

[Docket No. FAA-2014-0617; Directorate Identifier 2014-CE-019-AD; 
Amendment 39-17962; AD 2014-17-09

Airworthiness Directives; Various de Havilland Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

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 requires inspecting the aircraft 
maintenance records and/or the installed lateral fuselage tie rods and

[[Page 52178]]

attaching nuts to determine the origin of manufacture. This AD also 
requires immediately replacing lateral fuselage tie rods and attaching 
nuts produced by a specific manufacturer. 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. We are 
issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective September 18, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
18, 2014.
    We must receive comments on this AD by October 20, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received a report from the Australia Transportation Safety Board 
(ASTB) of accident investigation results on a de Havilland Model DH 82A 
airplane, which had a wing failure in flight. Investigation revealed 
that both of the accident airplane's fuselage lateral tie rods, which 
join the lower wings to the fuselage, were found fractured in three of 
the four threaded sections near the join with the left wing. The failed 
lateral fuselage tie rods, part number JRA-776-1, were under an 
Australian parts manufacturing approval (PMA) and were found to have 
different characteristics than the OEM parts.
    Although the defective PMA parts were manufactured in Australia, 
some airplanes of U.S. registry may have the PMA parts installed.
    De Havilland Model DH 82A airplanes (commonly referred to as Tiger 
Moths) are type certificated under two type certificates. TCDS A5PC, 
currently held by Harry E. Williams, is for airplanes built in 
Australia, and TCDS A8EU, currently held by Cliff Robertson, c/o 
Gadbois Business Management, is for airplanes built in the United 
Kingdom. This type certification approval was not by validation, but by 
an acceptance process; as such, the U.S. type certificate holders are 
not the manufacturers of the airplanes and the original manufacturers 
(de Havilland and its licensees) are not type certificate holders.
    De Havilland Support Ltd (DHSL) holds the type certificate 
responsibility for de Havilland Model DH 82A airplanes (the type design 
for TCDS A8EU) in the United Kingdom.
    DHSL is custodian of the airframe design data, manufacturing 
drawings, and repair schemes still in existence for de Havilland Model 
DH 82A Tiger Moth series airplanes only. In 2012, DHSL entered into a 
CAA Type Responsibility Agreement (TRA) so that the airplane remains 
eligible, if required, for an ICAO-compliant Certificate of 
Airworthiness to facilitate training and pleasure flying.
    Similarly, Air Stratus Ltd holds the type certificate 
responsibility for de Havilland Model DH 83 airplanes (the type design 
for TCDS 2-439) in the United Kingdom.
    The process for making mandatory continuing airworthiness 
information (MCAI) issued by an aviation authority of another country 
mandatory for airplanes of U.S. registry is through rulemaking.
    This condition, if not corrected, could result in structural 
failure of the attachment of the wing to the fuselage. We are issuing 
this AD to correct the unsafe condition on these products.

Relevant Service Information

    We reviewed British Aerospace Military Aircraft and Aerostructures 
BAe Aircraft Bulletin for de Havilland Moth Aircraft, Document Type and 
Ref No Technical News Sheet CT (Moth) No 29, Issue 3, dated March 1, 
1999, which was approved by the Civil Aviation Authority (CAA) for the 
United Kingdom to ensure the continued airworthiness of these airplanes 
in the United Kingdom. The service information describes procedures for 
replacing the lateral tie rods and attaching nuts.

FAA's Determination

    We are issuing 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.

[[Page 52179]]

AD Requirements

    This AD requires inspecting the aircraft maintenance records and/or 
the installed lateral fuselage tie rods and attaching nuts to determine 
if they were produced by J & R Aerospace Pty Ltd. This AD also requires 
replacing all lateral fuselage tie rods and attaching nuts produced by 
J & R Aerospace Pty Ltd with airworthy parts.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
structural failure of the attachment of the wing to the fuselage could 
result in loss of control. Therefore, we find that notice and 
opportunity for prior public comment are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2014-0617 and 
Directorate Identifier 2014-CE-019-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
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 AD.

Costs of Compliance

    We estimate that this AD affects 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.
