**Airworthiness Directives; BAE Systems (Operations) Limited**  **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 all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The existing AD currently requires revising the maintenance program by incorporating certain airworthiness limitations that require new life limits on certain main landing gear (MLG) components. Since we issued that AD, we have determined that reduced safe life limits on certain nose landing gear (NLG) fittings are necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which might reduce the life limits of these fittings. This proposed AD would require revising the maintenance program to


### 44470 Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Proposed Rules

incorporate certain limitations. We are proposing this AD to prevent fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane.

**DATES :**  We must receive comments on this proposed AD by September 9, 2013.

**ADDRESSES :**  You may send comments by any of the following methods:

Discussion

On November 8, 2011, we issued AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), which superseded AD 2010–10–22, Amendment 39–16301 (75 FR 28463, May 21, 2010). AD 2011–24–06 required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), we have determined that reduced safe life limits on certain NLG fittings are necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which might reduce the life limits of these fittings. In addition, the aircraft maintenance manual has been revised to redefine the operating time of the aileron and elevator dampers. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0004, dated January 12, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

* * * Compliance with [certain chapters of the BAe 146/AVRO 146–RJ Aircraft Maintenance Manual (AMM)] has been identified as a mandatory action for continued airworthiness and EASA AD 2011–0048 was issued to require operators to comply with those instructions.

* * * * * Failure to comply with these instructions could result in an unsafe condition.

For the reasons described above, this EASA AD retains the requirements of EASA AD 2011–0048 [which corresponds to FAA AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011)], which is superseded, and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in * * * [certain] sub-chapters of Chapter 05 of the AMM at
Revision 105 * * *. The unsafe condition is fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

BAE Systems (Operations) Limited has issued the following service information. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

• Subject 05–10–15, ‘‘Aircraft Equipment Airworthiness Limitations,’’ of Chapter 05, ‘‘Time Limits/ Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011.

• Subject 05–20–02, ‘‘Airframe Scheduled Maintenance—Landing/ Calendar Life Extended,’’ of Chapter 05, ‘‘Time Limits/Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011.

• Subject 05–20–05, ‘‘Airframe Scheduled Maintenance—Life Extension Programme Landings Life Extended,’’ of Chapter 05, ‘‘Time Limits/Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011.
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. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and/or Critical Design Configuration


### 44471 Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Proposed Rules

Control Limitations (CDCCLs). Compliance with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) according to paragraph (n) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.
Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 2 products of U.S. registry.

The actions that are required by AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), and retained in this proposed AD take about 2 work-hours per product, at an average labor rate of $85 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the currently required actions is $170 per product.

We estimate that it would take about 1 work-hour per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be up to $170, or $85 per product.
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 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 this 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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

**14 CFR Part 39**

**[Docket No. FAA–2013–0626; Directorate Identifier 2012–NM–180–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; Dassault Aviation Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all DASSAULT AVIATION Model FAN JET FALCON; Model MYSTERE–FALCON 200 airplanes; and Model MYSTERE– FALCON 20–C5, 20–D5, 20–E5, and 20– F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher bottle cartridges. This proposed AD would require checking manufacturing references of pyrotechnical cartridges for batch number and date, repetitive checking of cartridges for electrical continuity, and replacing defective pyrotechnical cartridges if necessary. We are proposing this AD to detect and correct defective fire bottle cartridges, which could affect the capability to extinguish a fire in an engine, auxiliary power unit, or rear compartment, which could result in damage to the airplane and injury to the occupants.
