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-
-
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:
Are consistent with the intent that was proposed in the NPRM (August 16, 2012, 77 FR 49389) for correcting the unsafe condition; and
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:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspect the horizontal 24 work-hours x Not Applicable.............. $2,040 $516,120

----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacement that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements:
On-Condition Costs

----------------------------------------------------------------------------------------------------------------
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.

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. However; the horizontal stabilizer attachment fitting must have been removed from the airplane during the inspection.
(2) This AD provides credit for the actions in paragraphs (h)(2) and (j)(1) of this AD, if the horizontal stabilizer attachment fitting has been replaced before the effective date of this AD, following 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.
(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 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 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 AD).
(2) For COLONIAL C-1 airplanes: Before or when the horizontal stabilizer attachment fitting accumulates 850 hours TIS or within 25 hours TIS after June 13, 2013 (the effective date of this AD), 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 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.
