SUMMARY: We are adopting a new 

airworthiness directive (AD) for all Bae 

Systems (Operations) Limited Model 

BAe 146 series airplanes and Model 

Avro 146–RJ series airplanes. This AD 

was prompted by reports of excess 

solder deposited during overhaul on the 

frangible plug of a fire extinguisher, 

which prevented the release of the 

extinguishant. This AD requires a onetime inspection of certain engine and 

auxiliary power unit (APU) fire 

extinguishers to determine if the fire 

extinguishers are affected by excessive 

solder and corrective actions if 

necessary. We are issuing this AD to 

prevent the failure of a fire extinguisher 

to discharge, which reduces the ability 

of the fire protection system to 

extinguish fires in the engine or APU 

fire zones, possibly resulting in damage 

to the airplane and injury to the 

passengers. 

DATES: This AD becomes effective 

March 14, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to 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 September 25, 2013 (78 FR 

58960). The NPRM was prompted by 

reports of excess solder deposited 

during overhaul on the frangible plug of 

a fire extinguisher, which prevented the 

release of the extinguishant. The NPRM 

proposed to require a one-time 

inspection of certain engine and 

auxiliary power unit (APU) fire 

extinguishers to determine if the fire 

extinguishers are affected by excessive 

solder and corrective actions if 

necessary. We are issuing this AD to 

prevent the failure of a fire extinguisher 

to discharge, which reduces the ability 

of the fire protection system to 

extinguish fires in the engine or APU 

fire zones, possibly resulting in damage 

to the airplane and injury to the 

passengers. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0126R1, 

dated September 10, 2012 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

A fire handle on a BAe 146 aeroplane was 

operated on the ground as a precautionary 

measure after the throttle cable on the 

affected engine failed, due to corrosion. The 

extinguisher failed to discharge. 

Investigation results revealed that excess 

solder, which had been deposited during 

overhaul on the frangible plug of the 

extinguisher, prevented the release of the 

extinguishant. Prompted by this report, 

Kidde Graviner, the fire extinguisher 

manufacturer, identified four further 

extinguishers of similar design that had the 

same issue. 

This condition, if not detected and 

corrected, could result in the failure of a fire 

bottle to discharge, which reduces the ability 

of the fire protection system to extinguish 

fires in the engine or Auxiliary Power Unit 

(APU) fire zones, possibly resulting in 

damage to the aeroplane and injury to the 

occupants. 

For the reasons described above, EASA 

issued AD 2012–0126 to require a one-time 

inspection of the affected Part Number (P/N) 

57333 engine and APU fire extinguishers. In 

addition, this [EASA] AD prohibited 

installation of a fire extinguisher, unless it 

has passed the inspection as required by 

[EASA] AD 2012–0126. 

Revision 1 of this [EASA] AD is issued to 

clarify that new extinguishers P/N 57333 may 

be fitted with no additional inspection 

required by this [EASA] AD. 

Required actions include installing a 

new unit or overhauling the unit if any 

solder is found during the inspection. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov/#!documentDetail;

D=FAA-2013-0793-0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 58960, September 25, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this 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 (78 FR 

58960, September 25, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 58960, 

September 25, 2013). 

Costs of Compliance 

We estimate that this AD affects 1 

airplane of U.S. registry. 

We also estimate that it will take 

about 1 work-hour 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 on U.S. 

operators to be $85, or $85 per product. 

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.
