Airworthiness Directives; Revo, Incorporated Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Revo, Incorporated Models COLONIAL C-1, COLONIAL C-2, LAKE 
LA-4, LAKE LA-4A, LAKE LA-4P, and LAKE LA-4-200 airplanes. That AD 
currently requires a one-time, dye-penetrant inspection of the 
horizontal stabilizer attachment fitting and repetitive visual 
inspections of the fitting for any evidence of fretting, cracking, or 
corrosion (with necessary replacement and modification); replacement of 
the fitting upon reaching the 850-hours time-in-service (TIS) safe 
life; and reporting to the FAA the results of the initial inspection 
and any cracks found on repetitive inspections. This new AD requires 
the same actions of AD 2005-12-02 except using revised service 
documents and procedures, adds Model COLONIAL C-1 airplanes to the 
Applicability, and adds an optional terminating action for the 
requirements. This AD was prompted by a report from Revo, Incorporated 
that, while the drawing numbers are different, the attachment fittings 
on the Model COLONIAL C-1 airplanes are identical in every other 
respect to those installed on the airplanes referenced in AD 2005-12-
02. We are issuing this AD to correct the unsafe condition on these 
products.

DATES: This AD is effective June 13, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of June 13, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in the AD as of July 8, 
2005 (70 FR 33820, June 10, 2005).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2005-12-02, amendment 39-14118 (70 FR 33820, 
June 10, 2005). That AD applies to the specified products. The NPRM 
published in the Federal Register on August 16, 2012 (77 FR 49389). 
That NPRM proposed to require the same actions of AD 2005-12-02, add 
Model COLONIAL C-1 airplanes to the Applicability, and add an optional 
terminating action for the requirements.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 49389, August 16, 
2012) or on the determination of the cost to the public.
    We did notice that the date for XLS Company's instructions for 
continued airworthiness was incorrect. We also identified the need to 
clarify giving credit for work done following previous service 
documents and procedures so the actions would not be unnecessarily 
duplicated.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for a 
typographical error in the date for XLS Company's instructions for 
continued airworthiness, clarification of credit allowed for work done 
following previous service documents and procedures, and minor 
editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (August 16, 2012, 77 FR 49389) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already

[[Page 27006]]

proposed in the NPRM (August 16, 2012, 77 FR 49389).

Costs of Compliance

    We estimate that this AD affects 253 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

    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.
    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.

Paperwork Reduction Act Burden Statement

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to be 
approximately 5 minutes per response, including the time for reviewing 
instructions, completing and reviewing the collection of information. 
All responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing the 
burden should be directed to the FAA at: 800 Independence Ave. SW., 
Washington, DC 20591, Attn: Information Collection Clearance Officer, 
AES-200.

(h) Dye Penetrant Inspection on the Horizontal Stabilizer Attachment 
Fitting

    (1) For airplanes with less than 825 hours time-in-service (TIS) 
on any horizontal stabilizer attachment fitting: Remove the 
horizontal stabilizer attachment (P/N 1-2200-14, 2200-14, or 2-2200-
21) from the airplane and do a one-time dye-penetrant inspection for 
cracks, fretting, or corrosion using the applicable compliance times 
and service information stated below.
    (i) For COLONIAL C-2, LAKE LA-4, LAKE LA-4A, LAKE LA-4P, and 
LAKE LA-4-200 airplanes: Within the next 25 hours TIS after July 8, 
2005 (the effective date of AD 2005-12-02 (70 FR 33820, June 10, 
2005)). Follow Revo Inc. Service Bulletin B-78 R3, Revision 3, dated 
January 10, 2012; Revo Inc. Service Bulletin B-78 R2, Revision 2, 
dated October 26, 2011; Revo Inc. Service Bulletin B-78 R1, Revision

and is retained in this AD).
    (ii) For COLONIAL C-1 airplanes: Within the next 25 hours TIS 
after June 13, 2013 (the effective date of this AD). Follow Revo 
Inc. Service Bulletin B-78 R3, Revision 3, dated January 10, 2012.
    (2) If cracks, fretting, or corrosion is found during the 
inspection required in paragraph (h)(1) of this AD, before further 
flight, replace the horizontal stabilizer attachment with an 
airworthy P/N 2-2200-21, P/N 1-2200-14, or 2200-14 following Revo 
Inc. Service Bulletin B-78 R3, Revision 3, dated January 10, 2012. 
After replacement with an airworthy part, the repetitive inspections 
specified in paragraph (i) of this AD and the repetitive 
replacements specified in paragraph (j) of this AD are still 
required.
    (3) For the purposes of this AD, an airworthy part is defined as 
a new part or a used part that has less than 850 hours TIS and has 
been inspected following paragraph (h)(1) of this AD and found free 
of cracks, fretting, or corrosion before installation.

(i) Repetitive Inspections of the Horizontal Stabilizer Attachment 
Fitting

    (1) Within 50 hours TIS or 12 months, whichever occurs first, 
after the dye-penetrant inspection required in paragraph (h)(1) of 
this AD or after replacement of the fitting required in paragraphs 
(h)(2), (i)(2), or (j) of this AD and repetitively thereafter at 
intervals not to exceed 50 hours TIS or 12 months, whichever occurs 
first, visually inspect the horizontal stabilizer attachment fitting 
using the following procedures:
    (i) Move the elevator as required to see the fitting, ensuring 
that the aft face of the fitting is visible.
    (ii) Clean the fitting. Pay special attention to the radius 
edges of the fitting just outboard of the fitting ear.
    (iii) Visually inspect the fitting for cracks using a flashlight 
(a small magnifying glass or borescope is recommended). Pay special 
attention again to the radius edges just outboard of the fitting 
ear. Also, inspect as far forward on the edge that is possible 
because some cracks progress along the forward face of the fitting 
that is mostly hidden by the horizontal stabilizer rear beam.
    (iv) Reference the sketch on page 1 of Revo Inc. Service 
Bulletin B-78 R3, Revision 3, dated January 10, 2012, to see where 
the crack is likely to begin.
    (2) If any cracks are found during any of the inspections 
required in paragraph (i) of this AD, before further flight, replace 
the fitting with an airworthy part following Revo Inc. Service 
Bulletin B-78 R3, Revision 3, dated January 10, 2012.
    (3) For the purposes of this AD, an airworthy part is defined as 
a new part or a used part that has less than 850 hours TIS and has 
been inspected following paragraph (h)(1) of this AD and found free 
of cracks, fretting, or corrosion before installation.

(j) Replace the Horizontal Stabilizer Attachment Fitting

    (1) For COLONIAL C-2, LAKE LA-4, LAKE LA-4A, LAKE LA-4P, and 
LAKE LA-4-200 airplanes: Before or when the horizontal stabilizer 
attachment fitting accumulates 850 hours TIS or within 25 hours TIS 
after July 8, 2005 (the effective date of AD 2005-12-02 (70 FR 
33820, June 10, 2005)), whichever occurs later, and repetitively 
thereafter at intervals not to exceed 850 hours TIS replace the 
horizontal stabilizer attachment fitting P/N 1-2200-14, 2200-14, or 
2-2200-21 with an airworthy part. Follow Revo Inc. Service Bulletin 
B-78 R3, Revision 3, dated January 10, 2012; Revo Inc. Service 
Bulletin B-78 R2, Revision 2, dated October 26, 2011; Revo Inc. 
Service Bulletin B-78 R1, Revision 1, dated July 26, 2005; or Revo 
Inc. Service Bulletin B-78, dated April 3, 1998 (which was 
incorporated by reference in AD 2005-12-02 and is retained in this
