Airworthiness Directives; BAE 

Systems (Operations) Limited 

Airplanes 

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 airplanes. 

This AD was prompted by reports of 

baggage bay fire bottles that can be 

misassembled such that two squib 

electrical connectors can be crossconnected. This AD requires a general 

visual inspection of certain baggage bay 

fire bottles for correct connection and 

for the length of the wiring loom, 

modification of the wiring loom to 

certain squib connectors, and corrective 

actions if necessary. We are issuing this 

AD to detect and correct excessive 

wiring loom length and improper 

connection of the squib connecters, 

which in conjunction with a fire in one 

of the baggage bays, could result in the 

fire extinguishing agent being 

discharged into a wrong compartment 

and consequent damage to the airplane. 

DATES: This AD becomes effective July 

30, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 30, 2012.

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 February 8, 2012 (77 FR 

6520). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

The baggage bay fire bottles of certain BAe 

146 and AVRO 146–RJ aeroplanes can be 

misassembled such that two squib electrical 

connectors can be cross-connected. This has 

been caused by an error in the baggage bay 

fire bottle Component Manufacturer Manual 

(CMM) and by excessive wiring loom length. 

This condition, if not corrected and in 

conjunction with a fire in one of the baggage 

bays, could result in the fire extinguishant to 

be discharged into a wrong compartment and 

consequent potential damage to the aircraft 

* * *. 

In addition to the CMM revision, to 

address this unsafe condition, BAE Systems 

developed modifications to reroute the 

baggage bay fire bottle wiring looms and 

prevent crossed electrical connections. 

For the reasons described above, this 

[EASA] AD requires the implementation of 

modifications HCM36250A and HCM36250B 

to affected aeroplanes. 

Required actions include general visual 

inspections of certain baggage bay fire 

bottles for correct connection and for 

the length of the wiring loom, 

modification of the wiring loom to 

certain squib connectors, and corrective 

actions if necessary. Corrective actions 

include reconnecting the squib 

connectors and modifying the loom to 

proper length. 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 6520, February 8, 2012) or on the 

determination of the cost to the public. 

Revised Heading and Wording for 

Credit Paragraph 

We have revised the heading and 

wording for paragraph (h) of this AD. 

This change does not affect the intent of 

that paragraph. 

Conclusion 

We reviewed the available, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously— 

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 6520, 

February 8, 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 6520, 

February 8, 2012). 

Costs of Compliance 

We estimate that this AD will affect 1 

product of U.S. registry. We also 

estimate that it will take about 6 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $170 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operator to be $680 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 3 work-hours and require parts 

costing $170, for a cost of $425 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; 


erowe on DSK2VPTVN1PROD with RULES
37776 Federal Register / Vol. 77, No. 122 / Monday, June 25, 2012 / Rules and Regulations 

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 6520, 

February 8, 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

section. Comments will be available in 

the AD docket shortly after receipt.

14 CFR Part 39

RIN 2120–AA64 

Airworthiness Directives; Eurocopter 

Deutschland GmbH Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

all Eurocopter Deutschland GmbH 

(ECD) Model MBB–BK 117 C–2 

helicopters. That AD currently requires 

revising the ‘‘Emergency and 

Malfunction Procedures’’ and 

‘‘Performance Data’’ sections of the 

Rotorcraft Flight Manual (RFM) by 

inserting three temporary pages into the 

RFM to alert pilots to monitor the power 

display when a generator is deactivated 

and provides procedures to prevent 

failure of the remaining generator. 

Before we issued that AD, the 

manufacturer developed a procedure to 

modify the two ‘‘After Junction Boxes’’ 

by removing a diode from each box, 

which provides terminating action for 

our AD requirements. These actions are 

intended to require implementing this 

terminating action to prevent an 

electrical power system failure and 

subsequent loss of control of the 

helicopter and revising the RFM 

accordingly, by removing the temporary 

pages inserted to comply with the 

superseded AD. 

DATES: This AD becomes effective July 

10, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain documents listed in this AD 

as of July 10, 2012. 

We must receive comments on this 

AD by August 24, 2012.
