SUPPLEMENTARY INFORMATION: DATES: Federal Aviation Administration Discussion 14 CFR Part 39 We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new AD for all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The NPRM published in the Federal Register on July 24, 2013 (78 FR 44469). The NPRM would have superseded AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011). The NPRM would have continued to require existing limitations and would have required revising the maintenance program to incorporate the following limitations: • 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 [Docket No. FAA–2013–0627; Directorate Identifier 2012–NM–021–AD] RIN 2120–AA64 Airworthiness Directives; BAE Systems (Operations) Limited Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Proposed rule; withdrawal. AGENCY: The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), which would have applied to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The NPRM would have superseded AD 2011–24–06 and required revising the maintenance program to incorporate new airworthiness limitations for reduced safe life limits on certain nose landing gear fittings.

The NPRM was prompted by a determination that reduced safe life limits on certain nose landing gear NLG fittings were necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which could reduce the life limits of these fittings. The proposed actions were intended to prevent fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane. Actions Since NPRM (78 FR 44469, July 24, 2013) Was Issued Since we issued the NPRM (78 FR 44469, July 24, 2014), BAE Systems (Operations) Limited has revised Chapter 05, ‘‘Time Limits/Maintenance Checks,’’ of the BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual (AMM). Therefore, the NPRM proposal to incorporate new airworthiness limitations with reduced safe life limits on certain nose landing gear fittings contained in a previous issue of the AMM are no longer relevant. FAA’s Conclusions Upon further consideration, we have determined that the changes to the AMM proposed in the NPRM (78 FR 44469, July 24, 2013) are no longer relevant and there is no benefit to proceeding with the publication of a final rule. Accordingly, the NPRM is withdrawn. The FAA is considering issuing a different rulemaking action to require implementation of the current revision of BAE Systems (Operations) Limited Chapter 05, ‘‘Time Limits/ Maintenance Checks,’’ of the BAe 146 Series/AVRO 146–RJ Series AMM. Withdrawal of the NPRM (78 FR 44469, July 24, 2013) does not preclude the FAA from issuing another related action or commit the FAA to any course of action in the future. Regulatory Impact Since this action only withdraws an NPRM (78 FR 44469, July 24, 2013), it is neither a proposed nor a final rule and therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to certain AEC replacement PMA cylinder assemblies marketed by ECi. These assemblies are used on Continental Motors, Inc. (CMI) model 520 and 550 reciprocating engines, and all other CMI engine models approved for the use of models 520 and 550 cylinder assemblies such as the CMI model 470 when modified by STC. The NPRM published in the Federal Register on August 12, 2013 (78 FR 48828). The NPRM proposed to require initial and repetitive inspections, immediate replacement of cracked cylinder assemblies, and replacement of cylinder assemblies at reduced times-inservice (TIS) since new. The NPRM also proposed to prohibit the installation of affected cylinder assemblies into any engine. We subsequently issued an SNPRM which published in the Federal Register on January 8, 2015 (80 FR 1008). The SNPRM proposed a modified schedule for removal of the affected cylinder assemblies, added that overhauled affected cylinder assemblies be removed within 80 hours, eliminated a reporting requirement, and removed the requirement for initial and repetitive inspections. Actions Since Previous SNPRM Was Issued Since we issued the SNPRM (80 FR 1008, January 8, 2015), we received numerous additional comments on the proposed rule. After reviewing the comments, we decided to reopen the docket so that we could provide additional information to explain the rationale for this AD action. We also wanted to provide commenters with the opportunity to comment on this additional information. We added the following information to Docket No. FAA–2012–0002: (1) The risk analysis conducted by the FAA’s Chief Scientific and Technical Adviser, Aircraft Safety Analysis; (2) a risk analysis using the Small Airplane Risk Analysis methods; (3) a June 2011, presentation by Airmotive Engineering to the FAA E:\FR\FM\28AUP1.SGM 28AUP1

SUPPLEMENTARY INFORMATION: 

Discussion

    We proposed to amend part 39 of the Federal Aviation Regulations 
(14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new 
AD for all BAE Systems (Operations) Limited Model BAe 146 series 
airplanes and Model Avro 146-RJ series airplanes. The NPRM published in 
the Federal Register on July 24, 2013 (78 FR 44469). The NPRM would 
have superseded AD 2011-24-06, Amendment 39-16870 (76 FR 73477, 
November 29, 2011). The NPRM would have continued to require existing 
limitations and would have required revising the maintenance program to 
incorporate the following limitations:
     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.
    The NPRM was prompted by a determination that reduced safe life 
limits on certain nose landing gear NLG fittings were necessary. 
Analysis of these fittings showed the presence of forging indications 
in the flash line, which could reduce the life limits of these 
fittings. The proposed actions were intended to prevent fatigue 
cracking of certain structural elements, which could adversely affect 
the structural integrity of the airplane.

Actions Since NPRM (78 FR 44469, July 24, 2013) Was Issued

    Since we issued the NPRM (78 FR 44469, July 24, 2014), BAE Systems 
(Operations) Limited has revised Chapter 05, ``Time Limits/Maintenance 
Checks,'' of the BAe 146 Series/AVRO 146-RJ Series Aircraft Maintenance 
Manual (AMM). Therefore, the NPRM proposal to incorporate new 
airworthiness limitations with reduced safe life limits on certain nose 
landing gear fittings contained in a previous issue of the AMM are no 
longer relevant.

FAA's Conclusions

    Upon further consideration, we have determined that the changes to 
the AMM proposed in the NPRM (78 FR 44469, July 24, 2013) are no longer 
relevant and there is no benefit to proceeding with the publication of 
a final rule. Accordingly, the NPRM is withdrawn. The FAA is 
considering issuing a different rulemaking action to require 
implementation of the current revision of BAE Systems (Operations) 
Limited Chapter 05, ``Time Limits/Maintenance Checks,'' of the BAe 146 
Series/AVRO 146-RJ Series AMM.
    Withdrawal of the NPRM (78 FR 44469, July 24, 2013) does not 
preclude the FAA from issuing another related action or commit the FAA 
to any course of action in the future.

Regulatory Impact

    Since this action only withdraws an NPRM (78 FR 44469, July 24, 
2013), it is neither a proposed nor a final rule and therefore is not 
covered under Executive Order 12866, the Regulatory Flexibility Act, or 
DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 
1979).
