AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all BAE 

SYSTEMS (OPERATIONS) LIMITED 

Model BAe 146 and Avro 146–RJ series 

airplanes. This 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 AD 

requires a one-time insulation resistance 

test of ceramic terminal blocks, and if 

necessary, replacement of the 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. 

DATES: This AD becomes effective April 

11, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 11, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on November 5, 2012 (77 FR 

66415). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (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 

[European Aviation Safety Agency (EASA)] 

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. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 66415, November 5, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

66415, November 5, 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 66415, 

November 5, 2012). 

Costs of Compliance 

We estimate that this AD will affect 2 

products of U.S. registry. We also 

estimate that it will take about 10 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the 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 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM (77 FR 66415, 

November 5, 2012), the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

–700, –800, and –900ER series 

airplanes. This AD was prompted by 

incorrect wire support clamps installed 

within the left environmental control 

systems (ECS) bay, which could allow 

wiring to come in contact with the 

exposed metal of the improper clamp. 

This AD requires inspections to identify 

the part number of the wire support 

clamp, related investigative actions, and 

corrective actions if necessary. We are 

issuing this AD to prevent electrical 

arcing and a potential ignition source 

within the ECS bay, which in 

combination with flammable fuel 

vapors, could result in a center wing 

fuel tank explosion, and consequent loss 

of the airplane. 

DATES: This AD is effective April 11, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 11, 2013.
