document also announced a public 

meeting to receive comment about the 

proposed standards and associated 

analyses and results. 80 FR 39486. The 

document provided for the submission 

of written comments by September 8, 

2015, and oral comments were also 

accepted at a public meeting held on 

July 28, 2015. 

The Plumbing Manufacturers 

International requested, by letter dated 

August 13, 2015, an extension of the 

public comment period for the proposed 

rulemaking, in view of the scope of the 

proposed rulemaking, technical nature, 

and amount of data requested. 

DOE has determined that an extension 

of the public comment period for the 

notice of proposed rulemaking is 

appropriate to allow interested parties 

additional time to submit comments for 

DOE’s consideration. Thus, DOE is 

extending the comment period by 15 

days. DOE will consider any comments 

received prior to September 23, 2015, to 

be timely submitted.

ACTION: Proposed rule; withdrawal. 

SUMMARY: 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The NPRM would have superseded AD 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. Since the NPRM 

was issued, we have received new data 

indicating that the airworthiness 

limitations contained in section 5 of the 

aircraft maintenance manual has been 

revised to include additional tasks and 

limitations. Accordingly, the NPRM is 

withdrawn. 

DATES: As of August 28, 2015, the 

proposed rule, which was published in 

the Federal Register on July 24, 2013 

(78 FR 44469), is withdrawn. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

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The NPRM would have superseded AD 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).

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Airmotive Engineering Corp. 

(AEC) replacement parts manufacturer 

approval (PMA) cylinder assemblies 

marketed by Engine Components 

International Division (ECi). We 

subsequently issued an initial 

supplemental NPRM (SNPRM) that 

proposed to modify the 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 a 

requirement for initial and repetitive 

inspections. This second SNPRM 

reopens the comment period to allow 

the public the chance to comment on 

additional information added to the 

docket of this proposed rule. We are 

proposing this SNPRM to prevent 

failure of the cylinder assemblies, which 

could lead to failure of the engine, inflight shutdown, and loss of control of 

the airplane. 

DATES: We must receive comments on 

this SNPRM by September 28, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

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
