7382 Federal Register / Vol. 79, No. 26 / Friday, February 7, 2014 / Rules and Regulations 

the FAA amends 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 adding 

the following new AD: 

2014–01–04 Bae Systems (Operations) 

Limited: Amendment 39–17727. Docket 

No. FAA–2013–0793; Directorate 

Identifier 2012–NM–138–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective March 14, 2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bae Systems 

(Operations) Limited Model BAe 146–100A, 

–200A, and –300A airplanes; and Model 

Avro 146–RJ70A, 146–RJ85A, and 146– 

RJ100A airplanes; certificated in any 

category; all models, all serial numbers. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 26, Fire protection. 

(e) Reason 

This AD was prompted by reports of excess 

solder deposited during overhaul on the 

frangible plug of the extinguisher, which 

prevented the release of the extinguishant. 

We are issuing this AD to prevent the failure 

of a fire extinguisher to discharge, which 

reduces the ability of the fire protection 

system to extinguish fires in the engine or 

auxiliary power unit (APU) fire zones, 

possibly resulting in damage to the airplane 

and injury to the passengers. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Inspection and Corrective Action 

For airplanes equipped with fire 

extinguishers manufactured by Kidde 

Graviner Limited having part number (P/N) 

57333 (all dash numbers): Within 12 months 

after the effective date of this AD, do an 

x-ray inspection to determine if there is 

solder between the operating head and 

container of the fire extinguishers in the 

engine and APU, in accordance with the 

Accomplishment Instructions of Bae Systems 

(Operations) Limited Inspection Service 

Bulletin ISB. 26–078, dated September 21, 

2011; or Kidde Graviner Service Bulletin 26– 

080, Revision 1, dated July 27, 2011; as 

applicable. 

(1) If any solder is found, before further 

flight, do the action specified in paragraph 

(g)(1)(i) or (g)(1)(ii) of this AD, in accordance 

with the Accomplishment Instructions of 

Kidde Graviner Service Bulletin 26–080, 

Revision 1, dated July 27, 2011. 

(i) Overhaul the fire extinguisher and 

install. An overhaul includes the 

replacement of the operating head. 

Replacement of the pressure relief plug 

assembly only is not considered an overhaul. 

(ii) Install a new fire extinguisher. 

(2) If no solder is found, no further action 

is required by this paragraph. 

(h) Parts Installation Limitation 

As of the effective date of this AD, no 

person may install a Kidde Graviner Limited 

fire extinguisher having P/N 57333 (any dash 

number), on any airplane, unless the fire 

extinguisher is new, or it has been 

determined that there is no solder between 

the operating head and container of the fire 

extinguishers as required by paragraph (g) of 

this AD, or has been overhauled in 

accordance with the Accomplishment 

Instructions of Kidde Graviner Service 

Bulletin 26–080, Revision 1, dated July 27, 

2011.

2D15 (Regional Jet Series 705) airplanes, 

and Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. AD 2011–03–13 

required repetitive inspections of the 

rudder travel limiter (RTL) return 

springs and primary actuator, and 

corrective actions if necessary. This new 

AD requires replacing certain RTL 

return springs, including doing related 

investigative and corrective actions, if 

necessary; which is terminating action 

for the repetitive inspections. This new 

AD also revises the applicability. This 

AD was prompted by reports of failure 

of the RTL return spring. We are issuing 

this AD to prevent failure of the RTL, 

which would permit an increase of 

rudder authority beyond normal 

structural limits and consequently affect 

the controllability of the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2011–03–13, 

Amendment 39–16597 (76 FR 6539, 

February 7, 2011). AD 2011–03–13 

applied to certain Bombardier, Inc. 

Model CL–600–2C10 (Regional Jet 

Series 700, 701, & 702) airplanes, Model 

CL–600–2D15 (Regional Jet Series 705) 

airplanes, and Model CL–600–2D24 

(Regional Jet Series 900) airplanes. The 

NPRM published in the Federal 

Register on September 24, 2012 (77 FR 

58787). The NPRM was prompted by 

reports of failure of the RTL return 

spring. The NPRM proposed to continue 

to require repetitive inspections of the 

rudder travel limiter (RTL) return 

springs and primary actuator, and 

corrective actions if necessary. The 

NPRM also proposed to require 

replacing certain RTL return springs, 

including doing related investigative 

and corrective actions, if necessary. The 

NPRM also proposed to revise the 

applicability. We are issuing this AD to 

prevent failure of the RTL, which would 

permit an increase of rudder authority 

beyond normal structural limits and 

consequently affect the controllability of 

the airplane. 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, has issued 

Canadian Airworthiness Directive CF– 

2010–18R1, dated March 19, 2012 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Rudder Travel Limiter (RTL) return spring, 

part number (P/N) E0650–069–2750S, failed 

prior to completion of the required 

endurance test. In addition, the replacement 

RTL return spring, P/N 670–93465–1 (see 

Note) was found to be susceptible to chafing 

on the primary actuator, which could also 

result in eventual dormant spring failure. 

There are two return springs in the RTL and 

if both springs failed, a subsequent 

mechanical disconnect of the RTL 

components would result in an 

unannunciated failure of the RTL. This, in 

turn, would permit an increase of rudder 

authority beyond normal structural limits 

and, in the event of a strong rudder input, the 

controllability of the aeroplane could be 

affected. 

Note: RTL return springs, P/N 670–93465– 

1, were installed in production aeroplanes 

serial number 10266 (CL–600–2C10) and 

15182 (CL–600–2D24) respectively and were 

introduced in-service by [Bombardier] 

Service Bulletin (SB) 670BA–27–047. 

[Bombardier] SB 670BA–27–047 has since 

been superseded by [Bombardier] SB 670BA– 

27–055. 

This [TCCA] AD mandates repetitive 

[detailed] visual inspection of the RTL [for 

broken] return springs and [damage through 

the casing or chafing of the casing of the] 

primary actuator, [and] replacement of parts 

as necessary. 

This revision mandates the installation of 

the RTL return spring, P/N BA670–93468–1, 

as a terminating action to this [TCCA] AD. 

This AD expands the applicability by 

adding Model CL–600–2C10 (Regional 

Jet Series 700, 701, & 702) airplane, 

serial number 10002. This AD also 

reduces the applicability by removing 

Model CL–600–2C10 (Regional Jet 

Series 700, 701, & 702) airplanes serial 

numbers 10334 and subsequent; and 

also removes Model CL–600–2D15, 

serial numbers 15289 and subsequent. 

The installation consists of replacing 

certain RTL return springs with new 

springs and doing related investigative 

and corrective actions, if necessary. The 

related investigative action is a detailed 

inspection of the casing of the primary 

actuator for signs of chafing or missing 

paint. Corrective actions include 

replacing any broken return spring with 

a new spring, repairing any chafing of 

the primary actuator on its casing, and 

replacing any primary actuator that has 

damage through its casing with a new 

actuator. You may examine the MCAI in 

the AD docket on the Internet at 

http://www.regulations.gov/

0003. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Correct Service Information 

Mesa Air Lines Inc. (Mesa) requested 

that we correct a step sequence in 

Bombardier Service Bulletin 670BA–27– 

059, Revision A, dated March 8, 2012. 

Mesa stated that step (6) of the job setup section, in Bombardier Service 

Bulletin 670BA–27–059, Revision A, 

dated March 8, 2012, specifies installing 

the rig pin. Mesa stated that it is not 

until step (10) that Bombardier Service 

Bulletin 670BA–27–059, Revision A, 

dated March 8, 2012, specifies removing 

panels 325DL and 325EL, and that 

removing these panels is necessary to 

install the rig pin. 

We agree with the commenter’s 

request regarding the incorrect step 

sequence. The manufacturer has issued 

Revision B to Bombardier Service 

Bulletin 670BA–27–059, dated 

September 26, 2013, which corrects the 

step sequence. We have revised 

paragraph (j) of this final rule to 

reference Bombardier Service Bulletin 

670BA–27–059, Revision B, dated 

September 26, 2013; and added 

Bombardier Service Bulletin 670BA–27– 

mstockstill on DSK4VPTVN1PROD with RULES

7384 Federal Register / Vol. 79, No. 26 / Friday, February 7, 2014 / Rules and Regulations 

059, Revision A, dated March 8, 2012, 

to paragraph (k)(2) in this final rule to 

provide credit for the actions required 

by paragraph (j) of this AD, if those 

actions were performed before the 

effective date of this AD. 

Request To Clarify Part Information 

Mesa observed that Bombardier 

Service Bulletin 670BA–27–059, 

Revision A, dated March 8, 2012, does 

not mention, reference, or address part 

number (P/N) BA670–93470–5 (rudder 

travel limiter). Mesa asked whether 

Bombardier Service Bulletin 670BA–27– 

059, Revision A, dated March 8, 2012, 

or the proposed AD (77 FR 58787, 

September 24, 2012) applies to its 

airplanes, since the service information 

does not reference P/N BA670–93470–5. 

We agree that clarification is 

necessary. Only paragraph (j) of this 

final rule refers to Bombardier Service 

Bulletin 670BA–27–059, Revision B, 

dated September 26, 2013. Paragraph (j) 

of this final rule affects airplanes having 

parts identified in paragraphs (j)(1) and 

(j)(2) of this final rule, and P/N BA670– 

93470–5 is not identified. Therefore, 

operators are not required to do the 

actions specified in paragraph (j) of this 

final rule on airplanes having P/N 

BA670–93470–5. 

However, airplanes having P/N 

BA670–93470–5 are still affected by this 

final rule. This AD applies to airplanes 

having serial numbers identified in 

paragraph (c) of this final rule; 

paragraph (c) of this final rule does not 

exclude airplanes having specific parts. 

All operators of the airplanes identified 

in applicability of this final rule must 

show compliance with the provisions of 

this final rule, including a 

determination that specific paragraphs 

do not apply. We have not changed this 

final rule in this regard. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

58787, September 24, 2012) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 58787, 

September 24, 2012). 

Costs of Compliance 

We estimate that this AD affects 366 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

= $680.

1,291 $1,971 .................................... $721,386. 

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 that 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.

This paragraph restates the requirements of 

paragraph (g) of AD 2011–03–13, 

Amendment 39–16597 (76 FR 6539, February 

7, 2011). Except for Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) airplane, 

serial number 10002, for airplanes that have 

accumulated 4,000 or less total flight hours 

as of March 14, 2011 (the effective date of AD 

2011–03–13): Before the accumulation of 

6,000 total flight hours, do a detailed 

inspection of the RTL for broken return 

springs and damage through the casing, or 

chafing of the casing of the primary actuator, 

in accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

670BA–27–055, Revision A, dated August 6, 

2010. Before further flight, replace any

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Eurocopter Model EC225LP and 

AS332L1 helicopters with emergency 

floatation gear. The AD requires, before 

the next overwater flight, inspecting the 

strap installation on the hinged rods of 

the emergency flotation gear on both 

rear cradles for correct installation. If a 

strap is installed under the hinged rod 

median plate rather than over it, 

reinstalling the strap is required. The 

AD is prompted by incorrect routing of 

the straps on the hinged rods of the 

emergency flotation gear rear cradles. 

The actions are intended to detect 

incorrect strap installation and prevent 

failure of the rods or straps upon 

deployment of the emergency flotation 

gear, incorrect float position, and 

subsequent capsizing of the helicopter. 

DATES: This AD becomes effective 

February 24, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain documents listed in this AD 

as of February 24, 2014.
