14 CFR Part 39
[Docket No. FAA-2005-21092; Directorate Identifier 2005-CE-20-AD;
Amendment 39-14118; AD 2005-12-02]
RIN 2120-AA64
Airworthiness Directives; Revo, Incorporated Models Colonial C-2,
Lake LA-4, Lake LA-4A, Lake LA-4P, and Lake LA-4-200 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) to
supersede Airworthiness Directive (AD) 98-10-12, which applies to all
Revo, Incorporated (REVO) (Type Certificate 1A13 formerly held by
Colonial Aircraft Company, Lake Aircraft Corporation, Consolidated
Aeronautics, Inc., and Global Amphibians LLC) Models Colonial C-2, Lake
LA-4, Lake LA-4A, Lake LA-4P, and Lake LA-4-200 airplanes. AD 98-10-12
currently requires you to ensure adequate clearance between the
attachment fitting and the horizontal stabilizer rear beam and between
the attachment fitting and the stabilizer skin with inspections,
possible replacement, and adjustments as necessary. This new AD is the
result of several reports of fatigue cracks found in the horizontal
stabilizer attachment fitting (part number 2-2200-21) of Model LA-4-200
airplanes that were in compliance with AD 98-10-12. This includes an
airplane accident with a fatality attributed to a fatigue crack in the
horizontal stabilizer attachment fitting. Consequently, this AD
requires either a dye penetrant inspection of the horizontal stabilizer
attachment fitting for any evidence of fretting, cracking, or corrosion
(with necessary replacement and modification) or replacement of the
fittings depending on the number of operational hours on the fitting.
The AD also requires you to repetitively replace the fitting every 850
hours time-in-service (TIS), repetitively inspect (visually) the
fittings between replacement times, and report to FAA the results of
the initial inspection and any cracks found on repetitive inspections.
We are issuing this AD to detect, correct, and prevent future cracks in
the horizontal stabilizer attachment fitting, which could result in
failure of the horizontal stabilizer attachment fitting. This failure
could result in loss of control of the airplane.
DATES: This AD becomes effective on July 8, 2005.
As of July 8, 2005, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.
We must receive any comments on this AD by August 8, 2005.

SUPPLEMENTARY INFORMATION:
Has FAA taken any action to this point? A report of loss of control
on a Revo, Incorporated (REVO) Lake LA-4 series airplane during flight
caused us to issue AD 98-10-12, Amendment 39-10524 (63 FR 26964, May
15, 1998). AD 98-10-12 currently requires the following on all REVO
(Type Certificate 1A13 formerly held by Colonial Aircraft Company, Lake
Aircraft Corporation, Consolidated Aeronautics, Inc., and Global
Amphibians LLC) Models Colonial C-2, Lake LA-4, Lake LA-4A, Lake LA-4P,
and Lake LA-4-200 airplanes:
Measuring for a clearance of \5/32\ of an inch between the
attachment fitting and the horizontal stabilizer rear beam.
If this minimum measurement is not met, removing the
affected horizontal tail half from the airplane and inspecting the
attachment fitting for any evidence of fretting, cracking, or
corrosion.
If cracks, fretting, or corrosion are/is present,
replacing the attachment fitting with a new fitting, ensuring a
clearance of \1/16\ of an inch exists between the attachment fitting,
and, if needed, trimming the stabilizer skin to provide a positive
clearance for the fitting.
What has happened since AD 98-10-12 to initiate this AD action? The
FAA has received more reports of fatigue cracks found in the horizontal
stabilizer attachment fitting (part number (P/N) 2-2200-21) of REVO
Model LA-4-200 airplanes. These airplanes were in compliance with AD
98-10-12. This includes one report of a REVO Model LA-4-200 airplane
accident with a fatality attributed to a fatigue crack in the
horizontal stabilizer attachment fitting.
The cracks occurred with as little as 942 hours time-in-service
(TIS) on the horizontal stabilizer attachment fitting.
What is the potential impact if FAA took no action? Failure of the
horizontal stabilizer attachment fitting (P/N 2-2200-21) could result
in loss of control of the airplane.
Is there service information that applies to this subject? REVO has
issued Service Bulletin B-78, dated April 3, 1998.
What are the provisions of this service information? The service
bulletin includes procedures for:
--Removing the fitting and inspecting (both visual and dye penetrant)
for cracks, fretting, or corrosion;
--Replacing the attachment fitting with a new fitting;
--Measuring the gap between the attachment fitting and the horizontal
[[Page 33821]]
stabilizer skin for proper clearance; and
--Trimming the stabilizer skin to provide proper clearance.
FAA's Determination and Requirements of the AD
What has FAA decided? We have evaluated all pertinent information
and identified an unsafe condition that is likely to exist or develop
on other products of this same type design.
Since the unsafe condition described previously is likely to exist
or develop on other REVO (Type Certificate 1A13 formerly held by
Colonial Aircraft Company, Lake Aircraft Corporation, Consolidated
Aeronautics, Inc., and Global Amphibians LLC) Models Colonial C-2, Lake
LA-4, Lake LA-4A, Lake LA-4P, and Lake LA-4-200 airplanes of the same
type design, we are issuing this AD to detect, correct, and prevent
future cracks in the horizontal stabilizer attachment fitting (P/N 2-
2200-21), which could result in failure of the horizontal stabilizer
attachment fitting. This failure could result in loss of control of the
airplane.
What does this AD require? This AD supersedes AD 98-10-12 by
requiring the following:
Dye penetrant inspection of the horizontal stabilizer
attachment fitting for any evidence of fretting, cracking, or corrosion
(with necessary replacement and modification) for those airplanes with
less than 825 hours TIS on the fitting;
Replacement of the fittings for those airplanes with 825
or more hours TIS on the fittings;
Repetitive replacement of the fitting every 850 hours
time-in-service (TIS);
Repetitive visual inspections of the fitting every 50
hours TIS (or at the next annual inspection) between the fitting
replacements; and
Submittal of a report to FAA on the findings of the
initial inspection and report of any cracks found for the repetitive
inspections.
In preparing this rule, we contacted type clubs and aircraft
operators to get technical information and information on operational
and economic impacts. As a result of this contact, we received a report
of an additional airplane with a crack in the fitting. This airplane
had 942 hours total TIS. Consequently, we adjusted the compliance times
in the AD based on this information.
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, we published a new version of 14 CFR part 39 (67 FR 47997, July
22, 2002), which governs FAA's AD system. This regulation now includes
material that relates to altered products, special flight permits, and
alternative methods of compliance. This material previously was
included in each individual AD. Since this material is included in 14
CFR part 39, we will not include it in future AD actions.
Comments Invited
Will I have the opportunity to comment before you issue the rule?
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 submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``Docket No. FAA-2005-21092;
Directorate Identifier 2005-CE-20-AD'' in the subject line of your
comments. If you want us to acknowledge receipt of your mailed
comments, send us a self-addressed, stamped postcard with the docket
number written on it; we will date-stamp your postcard and mail it back
to you. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it. If a person contacts us through a
nonwritten communication, and that contact relates to a substantive
part of this AD, we will summarize the contact and place the summary in
the docket. We will consider all comments received by the closing date
and may amend the AD in light of those comments.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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 AD.
Regulatory Findings
Will this AD impact various entities? We have determined that 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.
Will this AD involve a significant rule or regulatory action? 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 the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. 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.
We prepared a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``AD
Docket FAA-2005-21092; Directorate Identifier 2005-CE-20-AD'' in your
request.
