## 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.

**SUMMARY** 

### : We are superseding Airworthiness Directive (AD) 2011–03–


## 7383 Federal Register / Vol. 79, No. 26 / Friday, February 7, 2014 / Rules and Regulations

13 for 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. 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.

. 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–


## 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:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection [actions retained

from AD 2011–03–13, Amendment 39–16597 (76 FR 6539, February 7, 2011)]. 2 work-hours × $85 per hour = $170 per inspection cycle. $0 $170 per inspection cycle ...... $62,220 per inspection cycle.

Replacement [new action] ...... 8 work-hours × $85 per hour = $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.

**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.
