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, dyepenetrant 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

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 


tkelley on DSK3SPTVN1PROD with RULES
27006 Federal Register / Vol. 78, No. 90 / Thursday, May 9, 2013 / Rules and Regulations 

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

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspect the horizontal stabilizer attachment fitting.24 work-hours × $85 per hour = $2,040 .. Not Applicable ........... $2,040 $516,120 

Measure the gap between the horizontal 

skin and the horizontal stabilizer attachment fitting; trim the skin to provide gap.

1 work-hour × $85 per hour = $85 ........... Not Applicable ........... 85 21,505 

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

Action Labor cost Parts cost Cost per 

product 

Replace the horizontal stabilizer attachment fitting ..... 24 work-hours × $85 per hour = $2,040 ...................... $761 $2,801 

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 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 dyepenetrant 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

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding two 

existing airworthiness directives (AD) 

that apply to certain The Boeing 

Company Model 737–100, –200, –200C, 

–300, –400, and –500 series airplanes. 

Those ADs, for certain airplanes, 

currently require repetitive inspections 

of the flap track of the wing outboard 

flap, and corrective actions if necessary; 

and eventual rework of the flap track 

assembly and rear spar attachments. For 

certain airplanes, this new AD adds 

repetitive inspections, scheduled 

overhauls, correct alignment during 

installation, and repetitive maintenance 

of the flap track, and corrective actions 

if necessary. This new AD also adds 

airplanes to the applicability. This AD 

was prompted by reports that the work 

sequence and procedures used during 

installation of replacement tracks could 

cause loose or cracked tracks. We are 

issuing this AD to detect and correct 

cracking and damage in the flap track, 

which could cause loss of the outboard 

trailing edge flap and consequent 

reduced controllability of the airplane. 

DATES: This AD is effective June 13, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication 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 

this AD as of April 22, 2002 (67 FR 

11891, March 18, 2002). 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of January 2, 2001 (65 FR 

78913, December 18, 2000).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2000–25–07, 

Amendment 39–12041 (65 FR 78913, 

December 18, 2000); and AD 2002–05– 

07, Amendment 39–12675 (67 FR 

11891, March 18, 2002). Those ADs 

apply to the specified products, and 

require repetitive inspections of the flap 

track of the wing outboard flap, and 

corrective actions if necessary; and 

eventual rework of the flap track 

assembly and rear spar attachments. The 

NPRM published in the Federal 

Register on October 10, 2012 (77 FR 

61542). The NPRM proposed to retain 

all requirements of AD 2000–25–07 and 

AD 2002–05–07. For certain airplanes, 

the NPRM proposed to add repetitive 

inspections, scheduled overhauls, 

correct alignment during installation, 

and repetitive maintenance of the flap 

track, and corrective actions if 

necessary. This new AD also adds 

airplanes to the applicability. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 61542, 

October 10, 2012) and the FAA’s 

response to each comment. 

Concurrence 

Boeing and United concurred with the 

content of the NPRM (77 FR 61542, 

October 10, 2012). 

Request To Change Text of Paragraph 

(p)(3) of the NPRM (77 FR 61542, 

October 10, 2012) 

Alaska Airlines requested that we 

change the text of paragraph (p)(3) of the 

NPRM (77 FR 61542, October 10, 2012) 

to revise the descriptions of the 

inspection locations to be similar to the 

instructions included in Boeing 737 

Non Destructive Test (NDT) Manual Part 

6, 57–50–06. The commenter suggested 

that the existing wording in paragraph 

(p)(3) of the NPRM contradicts the 

instructions specified in Boeing 737 

NDT Manual Part 6, 57–50–06. 

We disagree with the request to 

change the text of paragraph (p)(3) of 

this AD. The inspections specified in 

paragraph (p)(3) of this AD must be 

done in accordance with paragraph 

3.B.3., ‘‘Inspection—Track Webs and 

Flanges,’’ of the Accomplishment 

Instructions of Boeing Service Bulletin 

737–57A1271, Revision 3, dated 

February 13, 2012. The instructions for 

accomplishing the eddy current 

inspection required by paragraph (p)(3) 

of this AD are detailed in Boeing 737 

NDT Manual Part 6, 57–50–06, which is 

an additional source of guidance. There 

is no contradiction in the instructions. 

No change has been made to the AD in 

this regard. 

Request for Revised Service 

Information 

Southwest Airlines requested that 

Boeing Service Bulletin 737–57A1271, 

Revision 3, dated February 13, 2012, be 

revised to add missing necessary data to 

support the rework requirements of 

paragraphs (s) and (t) of the NPRM (77 

FR 61542, October 10, 2012) for flap 

track part number (P/N) 65C34809–3. 

The commenter stated that paragraphs 

(s) and (t) of the NPRM require doing 

the corrective actions in accordance 

with Boeing Service Bulletin 737– 

57A1271, Revision 3, dated February 13, 

2012. The commenter also stated that 

Boeing Service Bulletin 737–57A1271, 

Revision 3, dated February 13, 2012, 

provides repair data, but the commenter 

noted that not all repair data are 

provided for flap track P/N 65C34809– 

3. The commenter added that Boeing
