ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to 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. The existing 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. Since we issued AD 2005–12–02, Revo, Incorporated informed the FAA 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. This proposed AD would retain the actions required by AD 2005–12–02, add the Model COLONIAL C–1 airplanes to the Applicability, and add an optional terminating action for the requirements. We are proposing this AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by October 1, 2012. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

VerDate Mar<15>2010 15:26 Aug 15, 2012 Jkt 226001 regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On June 2, 2005, we issued AD 2005– 12–02, amendment 39–14118 (70 FR 33820, June 10, 2005), for all Revo, Incorporated (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. That AD requires a onetime 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 TIS safe life; and reporting to the FAA the results of the initial inspection and any cracks found on repetitive inspections. That AD resulted from several reports of fatigue cracks found in the horizontal stabilizer attachment fitting (part number (P/N) 2– 2200–21) of Model LA–4–200 airplanes that were in compliance with AD 98– 10–12 (63 FR 26964, May 15, 1998). We issued that 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. Actions Since Existing AD Was Issued Since we issued AD 2005–12–02 (70 FR 33820, June 10, 2005), Revo, Incorporated on January 10, 2012, informed the FAA 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. Also, since we issued AD 2005–12–02 (70 FR 33820, June 10, 2005), we determined that installation of Supplemental Type Certificate (STC) SA02153NY (part number (P/N) LC– 2200–21) or STC SA03217AT (P/N XLS–2–2200–221L/R) terminates the requirements of this AD. The actions required in the instructions for continued airworthiness for the STCs would still apply to airplanes with those STCs installed. We propose to include PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 installation of STC SA02153NY or STC SA03217AT as options to this AD. Relevant Service Information We reviewed Revo, Inc. Service Bulletin B–78 R3, dated January 10, 2012; Revo, Inc. Service Bulletin B–78 R2, dated October 26, 2011; and Revo, Inc. Service Bulletin B–78, dated April 3, 1998. The service information describes 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 stabilizer skin for proper clearance; and • Trimming the stabilizer skin to provide proper clearance. We reviewed Lake Central Aircraft Services Lake Amphibian Stabilizer Fitting LC–2200–21 Installation Instructions, Rev B, dated August 26, 2005, and Lake Central Air Services Stabilizer Fitting LC–2200–21 Maintenance Manual Supplement Document MS–LC–2200–21, Rev B, dated August 26, 2005. The service information describes procedures for installation of the Lake Central Aircraft Services Lake Amphibian stabilizer fitting (STC SA02153NY). We reviewed XLS Company, LLC Report XLS–2–2200–500, Installation Instructions and Instructions for Continued Airworthiness, Revision B, November 18, 2005. The service information describes procedures for installation of the XLS Co., LLC horizontal stabilizer support fitting system (STC SA03217AT). FAA’s Determination We are proposing 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. Proposed AD Requirements This proposed AD would retain all requirements of AD 2005–12–02 (70 FR 33820, June 10, 2005), add airplanes to the Applicability section, and add an optional terminating action for the requirements of this AD. Costs of Compliance We estimate that this proposed AD affects 253 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\16AUP1.SGM 16AUP1 49391 Federal Register / Vol. 77, No. 159 / Thursday, August 16, 2012 / Proposed Rules ESTIMATED COSTS Cost per product Cost on U.S. operators Action Labor cost Parts cost Inspect the horizontal stabilizer attachment fitting ...................... 24 work-hours × $85 per hour = $2,040. 1 work-hour × $85 per hour = $85. Not Applicable $2,040 $516,120 Not Applicable 85 21,505 Measure the gap between the horizontal skin and the horizontal stabilizer attachment fitting; trim the skin to provide gap. We estimate the following costs to do any necessary replacement that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these replacements: ON-CONDITION COSTS Action Labor cost Replace the horizontal stabilizer attachment fitting .......... 24 work-hours × $85 per hour = $2,040 .......................... wreier-aviles on DSK7SPTVN1PROD with PROPOSALS 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: (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), (3) Will not affect intrastate aviation in Alaska, and VerDate Mar<15>2010 15:26 Aug 15, 2012 Jkt 226001 (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2005–12–02, Amendment 39–10524 (70 FR 33820, June 10, 2005), and adding the following new AD: Revo, Incorporated: Docket No. FAA–2012– 0845; Directorate Identifier 2012–CE– 013–AD. (a) Comments Due Date The FAA must receive comments on this AD action by October 1, 2012. (b) Affected ADs This AD supersedes AD 2005–12–02, Amendment 39–10524 (70 FR 33820, June 10, 2005). (c) Applicability This AD applies to the following Revo, Incorporated Models COLONIAL C–1, COLONIAL C–2, LAKE LA–4, LAKE LA–4A, LAKE LA–4P, and LAKE LA–4–200 PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 Parts cost $761 Cost per product $2,801 airplanes, all serial numbers, that are certificated in any category, and have installed horizontal stabilizer attachment fittings part number (P/N) 1–2200–14, 2200– 14, or 2–2200–21. (d) Subject Joint Aircraft System Component (JASC)/ Air Transport Association (ATA) of America Code 55: Stabilizers. (e) Unsafe Condition This AD was prompted by information 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 (70 FR 33820, June 10, 2005). We are issuing this AD to retain the actions required by AD 2005–12– 02, add the Model COLONIAL C–1 airplanes to the Applicability, and add an optional terminating action for the requirements. We are adopting this AD to correct the unsafe condition on these products. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) 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 inspect for cracks (using dye penetrant), fretting, or corrosion using the applicable compliance times stated below. To take ‘‘already done’’ credit for this inspection, you must have removed the horizontal stabilizer attachment from the airplane when the inspection was done. (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)).

PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2012–03, dated January 11, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: There has been one (1) reported in-service incident where the propeller de-icing system became unavailable due to burnt/chafed wires within the Alternating Current Contactor Box (ACCB). There has also been a number of additional minor events of wires found chafed within ACCBs. An investigation revealed that inadequate clearance between the wires and metallic structure within the ACCB could cause chafed wires. Damaged, chafed or loose wiring within an ACCB could affect the operation of the windshield heater, ice detector, angle of attack (AOA) vane heater, pitot probe heater, engine intake heater or propeller de-icing system. Loss of one of these systems could adversely affect the aeroplane’s flight characteristics in icing conditions. This [TCCA] Airworthiness Directive (AD) mandates the [visual] inspection [for damaged, chafed, and loose wiring within an ACCB and replace if necessary] and rectification [rework] of the wiring installation within each ACCB. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier, Inc. has issued the following service bulletins: • Bombardier Service Bulletin 84–24– 47, Revision A, dated September 14, 2011. • Bombardier Service Bulletin 84–24– 48, Revision A, dated September 14, 2011. • Bombardier Service Bulletin 84–24– 49, Revision A, dated September 14, 2011. • Bombardier Service Bulletin 84–24– 50, Revision A, dated September 14, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above.

Airworthiness Directives; Revo, Incorporated Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to 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. The existing 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. Since we issued AD 2005-12-02, Revo, Incorporated informed 
the FAA 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. This proposed AD would retain the actions required by AD 
2005-12-02, add the Model COLONIAL C-1 airplanes to the Applicability, 
and add an optional terminating action for the requirements. We are 
proposing this AD to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by October 1, 2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    On June 2, 2005, we issued AD 2005-12-02, amendment 39-14118 (70 FR 
33820, June 10, 2005), for all Revo, Incorporated (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. That AD 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 TIS safe life; and reporting to 
the FAA the results of the initial inspection and any cracks found on 
repetitive inspections. That AD resulted from several reports of 
fatigue cracks found in the horizontal stabilizer attachment fitting 
(part number (P/N) 2-2200-21) of Model LA-4-200 airplanes that were in 
compliance with AD 98-10-12 (63 FR 26964, May 15, 1998). We issued that 
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.

Actions Since Existing AD Was Issued

    Since we issued AD 2005-12-02 (70 FR 33820, June 10, 2005), Revo, 
Incorporated on January 10, 2012, informed the FAA 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.
    Also, since we issued AD 2005-12-02 (70 FR 33820, June 10, 2005), 
we determined that installation of Supplemental Type Certificate (STC) 
SA02153NY (part number (P/N) LC-2200-21) or STC SA03217AT (P/N XLS-2-
2200-221L/R) terminates the requirements of this AD. The actions 
required in the instructions for continued airworthiness for the STCs 
would still apply to airplanes with those STCs installed. We propose to 
include installation of STC SA02153NY or STC SA03217AT as options to 
this AD.

 Relevant Service Information

    We reviewed Revo, Inc. Service Bulletin B-78 R3, dated January 10, 
2012; Revo, Inc. Service Bulletin B-78 R2, dated October 26, 2011; and 
Revo, Inc. Service Bulletin B-78, dated April 3, 1998. The service 
information describes 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 stabilizer skin for proper clearance; and
     Trimming the stabilizer skin to provide proper clearance.
    We reviewed Lake Central Aircraft Services Lake Amphibian 
Stabilizer Fitting LC-2200-21 Installation Instructions, Rev B, dated 
August 26, 2005, and Lake Central Air Services Stabilizer Fitting LC-
2200-21 Maintenance Manual Supplement Document MS-LC-2200-21, Rev B, 
dated August 26, 2005. The service information describes procedures for 
installation of the Lake Central Aircraft Services Lake Amphibian 
stabilizer fitting (STC SA02153NY).
    We reviewed XLS Company, LLC Report XLS-2-2200-500, Installation 
Instructions and Instructions for Continued Airworthiness, Revision B, 
November 18, 2005. The service information describes procedures for 
installation of the XLS Co., LLC horizontal stabilizer support fitting 
system (STC SA03217AT).

FAA's Determination

    We are proposing 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.

Proposed AD Requirements

    This proposed AD would retain all requirements of AD 2005-12-02 (70 
FR 33820, June 10, 2005), add airplanes to the Applicability section, 
and add an optional terminating action for the requirements of this AD.

Costs of Compliance

    We estimate that this proposed AD affects 253 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (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),
    (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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 55: Stabilizers.

(e) Unsafe Condition

    This AD was prompted by information 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 (70 FR 33820, June 10, 2005). We are issuing this AD to retain 
the actions required by AD 2005-12-02, add the Model COLONIAL C-1 
airplanes to the Applicability, and add an optional terminating 
action for the requirements. We are adopting this AD to correct the 
unsafe condition on these products.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) 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 inspect for cracks (using dye penetrant), 
fretting, or corrosion using the applicable compliance times stated 
below. To take ``already done'' credit for this inspection, you must 
have removed the horizontal stabilizer attachment from the airplane 
when the inspection was done.
    (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

[[Page 49392]]

Revo Inc. Service Bulletin B-78 R3, dated January 10, 2012; or Revo 
Inc. Service Bulletin B-78 R2, dated April 3, 1998.
    (ii) For COLONIAL C-1 airplanes: Within the next 25 hours TIS 
after the effective date of this AD. Follow Revo Inc. Service 
Bulletin B-78 R3, dated January 10, 2012.
    (2) If cracks, fretting, or corrosion is found during the 
inspection required in either paragraph (g)(1)(i) or (g)(1)(ii) of 
this AD, before further flight, replace with P/N 2-2200-21. P/N 2-
2200-21 is an approved replacement for P/N 1-2200-14 or 2200-14. 
Follow Revo Inc. Service Bulletin B-78 R3, dated January 10, 2012.

(h) Repetitive Inspections of the Horizontal Stabilizer Attachment 
Fitting

    (1) For all airplanes: After the dye-penetrant inspection 
required in paragraph (g) of this AD or after replacement of the 
fitting, at intervals not to exceed 50 hours TIS or 12 months, 
whichever occurs first, repetitively inspect (visual) 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, dated January 10, 2012, to see where the crack is
