(d) Subject 

Air Transport Association of America 

(ATA) Code 76: Engine Controls. 

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as damage of 

the cable sliding end assembly and 

installation of the incorrect end fitting on 

engine control cable assemblies. We are 

issuing this AD to detect and correct damage 

of the cable sliding end assembly (cracking, 

distortion, corrosion) and incorrect end 

fittings on the engine control assemblies, 

which could lead to reduced engine control 

with consequent loss of control. 

(f) Actions and Compliance 

Unless already done, do the following 

actions in paragraphs (f)(1) through (f)(4) of 

this AD: 

(1) Within the next 6 months after April 1, 

2014 (the effective date of this AD), do a onetime inspection of the engine control cable 

assemblies, part number (P/N) 137835, P/N 

172449–1, P/N 17250, and P/N 172451, and 

surrounding areas for damage (cracking, 

distortion, corrosion) and correct cable endfitting and to assure the wire locking is intact 

following Britten-Norman Aircraft Limited 

Service Bulletin No. SB 334, Issue 1, dated 

August 30, 2013. 

(2) If no discrepancies are found during the 

inspection required in paragraph (f)(1) of this 

AD, inspect the control linkages for proper 

adjustment and, before further flight, make 

any necessary changes following BrittenNorman Aircraft Limited Service Bulletin No. 

SB 334, Issue 1, dated August 30, 2013. 

(3) If any discrepancies are found during 

the inspection required in paragraph (f)(1) of 

this AD and/or the control linkages cannot be 

properly adjusted as specified in paragraph 

(f)(2) of this AD, before further flight, replace 

the engine control cable assembly with a 

serviceable unit following Britten-Norman 

Aircraft Limited Service Bulletin No. SB 334, 

Issue 1, dated August 30, 2013. 

(4) After April 1, 2014 (the effective date 

of this AD), do not install on any airplane 

engine control cable assemblies, part number 

(P/N) 137835, P/N 172449–1, P/N 17250, and 

P/N 172451, unless they are new or have 

been inspected as required in paragraphs 

(f)(1) and (f)(2) of this AD and found free of 

any discrepancies and have proper 

adjustment.

SUPPLEMENTARY INFORMATION: 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations 10343 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to all Slingsby Aviation Ltd. 

Model T67M260 airplanes. That NPRM 

was published in the Federal Register 

on November 21, 2013 (78 FR 69785). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products and was based on mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country. The MCAI 

states: 

Several cases have been reported of 

cracked horizontal stabiliser attachment 

brackets on Slingsby T67 aeroplanes. 

This condition, if not detected and 

corrected, could lead to separation of the 

horizontal stabiliser and consequent loss of 

control of the aeroplane. 

Prompted by these reports, Slingsby issued 

Service Bulletin (SB) 179 to provide 

instructions for repetitive inspections. The 

CAA UK, the State of Design authority at the 

time, issued AD 001–12–2002,which was 

later superseded by AD G–2005–0004 (EASA 

approval 2005–564) to require repetitive 

inspections and, depending on findings, 

replacement of the affected brackets. 

Since that AD was issued, Slingsby 

published SB 179 issue 4, which removed the 

Model T67M260–T3A from the Applicability 

(all aeroplanes of this Model are confirmed 

to have been scrapped) and clarified that 

replacement of the affected aluminum 

brackets with titanium brackets (Slingsby 

Modification M988A or B) constitutes 

terminating action for the repetitive 

inspections. 

For the reasons described above, this AD 

retains the requirements of CAA UK AD G– 

2005–0004, which is superseded, removes 

the Model T67M260–T3A from the 

Applicability and confirms that installing 

titanium brackets constitutes terminating 

action for the repetitive inspection 

requirements of this AD. 

The MCAI can be found in the AD 

docket on the Internet at http://

www.regulations.gov/

#!documentDetail;D=FAA-2013-0997- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 69785, November 21, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

69785, November 21, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 69785, 

November 21, 2013). 

Costs of Compliance 

We estimate that this AD will affect 

11 products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with the 

basic inspection of the aluminum 

horizontal stabilizer attachment brackets 

requirement of this AD. The average 

labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $1,870, or $170 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 8 work-hours and require parts 

costing $7,250 (for all four titanium 

horizontal stabilizer attachment 

brackets), for a cost of $7,930 per 

product, or parts costing $9,557 (for all 

four aluminum horizontal stabilizer 

attachment brackets), for a cost of 

$10,237. We have no way of 

determining the number of products 

that may need these actions. 

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 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 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), 

(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.

in loss of control. 

(f) Actions and Compliance 

Unless already done, do the actions 

specified in paragraphs (f)(1) through (f)(4) of 

this AD: 

(1) Within the next 150 hours time-inservice (TIS) after April 1, 2014 (the effective 

date of this AD) or at the next annual 

inspection after April 1, 2014 (the effective 

date of this AD), whichever occurs later, and 

repetitively thereafter at intervals not to 

exceed 150 hours TIS, inspect the aluminum 

horizontal stabilizer attachment brackets for 

cracks. Do the inspections following the 

ACTION instructions in Slingsby Advanced 

Composites Ltd. Service Bulletin S.B. No: 

179, Issue 4, dated March 15, 2007. 

(2) If any cracks are found during any 

inspection required in paragraph (f)(1) of this 

AD, before further flight, replace the cracked 

bracket with a serviceable part. Do the 

replacement following the ACTION 

instructions in Slingsby Advanced 

Composites Ltd. Service Bulletin S.B. No: 

179, Issue 4, dated March 15, 2007. If a 

serviceable aluminum horizontal stabilizer 

attachment bracket is used as a replacement 

part, repetitively inspect as specified in 

paragraph (f)(1) of this AD. 

(3) To terminate the repetitive inspections 

required in paragraph (f)(1) of this AD, all 

four aluminum horizontal stabilizer 

attachment brackets must be replaced with 

titanium horizontal stabilizer attachment 

brackets. 

(4) After installing titanium horizontal 

stabilizer attachment brackets, installing 

aluminum horizontal stabilizer attachment 

brackets is prohibited.
