AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all BAE 

Systems (Operations) Limited Model 

BAe 146 and Avro 146–RJ series 

airplanes. This proposed AD was 

prompted by a report that certain 

ceramic terminal blocks, through which 

the wiring for the engine fire 

extinguishers, fire detection circuits, 

and engine and intake anti-ice system 

are routed, have been found to have 

moisture ingress which can degrade the 

insulation resistance of the ceramic 

terminal blocks. This proposed AD 

would require a one-time insulation 

resistance test of ceramic terminal 

blocks, and if necessary, replacement of 

the blocks. We are proposing this AD to 

prevent latent failure of the number 2 

fire bottle, which, in the event of an 

engine fire, could result in failure of the 

fire bottle to discharge when activated 

and possibly preventing the flightcrew 

from extinguishing an engine fire. 

DATES: We must receive comments on 

this proposed AD by December 20, 

2012. 

ADDRESSES: You may send comments by 

any of the following methods:

66416 Federal Register / Vol. 77, No. 214 / Monday, November 5, 2012 / Proposed Rules 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0040, 

dated March 13, 2012 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Moisture ingress has been discovered on 

certain ceramic terminal blocks, mounted on 

the engine cowlings, through which the 

wiring for the engine fire extinguishers, fire 

detection circuits and engine and intake anti 

ice system are routed. The affected terminal 

blocks were introduced through BAE 

Systems SB 71–077–01693A (modification 

HCM01693A) during the period 2002–2004, 

as this modification was mandated by CAA 

UK AD 005–10–2001 [which corresponds 

with FAA AD 2003–03–10, Amendment 39– 

13034 (68 FR 4902, January 31, 2003)]. 

Moisture ingress has a detrimental effect on 

the insulation resistance of the ceramic 

terminal block with the resultant possibility 

of interconnections between all terminals. 

Most of the possible failure conditions in the 

terminal block should result in an evident 

warning or other indication. However, the 

functional loss of the number 2 fire bottle 

would be a dormant failure. 

This condition, if not corrected, could 

result in the failure of a fire bottle to 

discharge when activated, possibly 

preventing the flight crew in extinguishing 

an engine fire. 

For the reasons described above, this AD 

requires a one-time inspection of the ceramic 

terminal blocks to determine the insulation 

resistance and, depending on findings, 

replacement of terminal blocks, and the 

reporting of the results to the BAE Systems. 

These will be used to establish a suitable 

repetitive inspection interval, which is 

expected to be introduced through the 

Maintenance Review Board (MRB) process. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

BAE Systems (Operations) Limited 

has issued Inspection Service Bulletin 

24–143, Revision 1, dated October 2, 

2012. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

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. 

Reporting Requirement 

Although the MCAI or service 

information tells you to submit 

information to BAE Systems 

(Operations) Limited, paragraph (i) of 

this AD specifies that such submittal is 

not required. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 2 products of U.S. registry. 

We also estimate that it would take 

about 10 work-hours per product to 

comply with the 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 

$1,700, or $850 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $949, for a cost of $1,034 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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:

WREIER-AVILES on DSK5TPTVN1PROD with PROPOSALS

Federal Register / Vol. 77, No. 214 / Monday, November 5, 2012 / Proposed Rules 66417 

which can degrade the insulation resistance 

of the ceramic terminal blocks. We are 

issuing this AD to prevent latent failure of 

the number 2 fire bottle, which, in the event 

of an engine fire, could result in failure of the 

fire bottle to discharge when activated and 

possibly preventing the flightcrew from 

extinguishing an engine fire. 

(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 

Within 4,000 flight cycles or 18 months, 

whichever occurs first after the effective date 

of this AD, do an insulation resistance test on 

each terminal block, in accordance with 

paragraphs 2.C., 2.D., 2.E., and 2.F. of the 

Accomplishment Instructions of BAE

October 2, 2012. 

(h) Replacement 

If, during the test required by paragraph (g) 

of this AD, any terminal block is found to 

have a value of less than 50 megohms, before 

next flight, replace it with a new or 

serviceable terminal block, in accordance 

with paragraph 2.G. of the Accomplishment 

Instructions of BAE Systems (Operations) 

Limited Inspection Service Bulletin 24–143, 

Revision 1, dated October 2, 2012. 

(i) Inspection Report Difference 

Where BAE Systems (Operations) Limited 

Inspection Service Bulletin 24–143, Revision 

1, dated October 2, 2012, specifies to 

complete the test result sheets in Appendices 

1, 2, 3, and 4 and the inspection report in 

Appendix 6, and send the information to 

BAE Systems (Operations) Limited, this AD 

does not require that action. 

(j) Credit for Previous Actions 

This paragraph provides credit for actions 

required by paragraphs (g) and (h) of this AD, 

if those actions were performed before the 

effective date of this AD using BAE Systems 

(Operations) Limited Inspection Service 

Bulletin 24–143, dated September 26, 2011,
