Airworthiness Directives; B/E 

Aerospace Protective Breathing 

Equipment Part Number 119003–11 

Installed on Various Transport 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for various 

transport airplanes equipped with 

certain B/E Aerospace protective 

breathing equipment (PBE) units. This 

proposed AD would require removing 

affected PBE units. This proposed AD 

results from reports of potentially 

defective potassium superoxide 

canisters used in PBE units, which 

could result in an exothermic reaction 

and ignition. We are proposing this AD 

to prevent PBE units from igniting, 

which could result in a fire and possible 

injury to the flightcrew or other persons. 

DATES: We must receive comments on 

this proposed AD by October 4, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

about this proposed AD. 

Discussion 

We have been notified that potassium 

superoxide canisters used in 119003–11 

protective breathing equipment ignited 

on a vendor’s test stand during quality 

assurance testing. Subsequent 

investigation revealed that potassium 

superoxide contained a high percentage 

of small particles that ignited. B/E 

Aerospace manufactured units with this 

chemical lot between February 15, 2010 

and March 6, 2010. B/E Aerospace 

shipped 600 canisters with this lot of 

chemicals to part distributers, airplane 

manufacturers (including Airbus, ATR, 

Boeing, Bombardier, Embraer, Fokker, 

and Hawker Beechcraft), and airlines 

(including Emirates, Korean Airlines, 

and Shenzhen Airlines). This condition, 

if not corrected, could result in 

potentially defective canisters being 

used in on-board PBE units. 

Relevant Service Information 

We have reviewed B/E Aerospace 

Service Bulletin 119003–35–5, dated 

April 19, 2010. This service bulletin 

describes procedures for doing an 

inspection to determine the serial 

number of the protective breathing 

equipment having part number 119003– 

11, and returning affected parts to B/E 

Aerospace. 

FAA’s Determination and Requirements 

of This Proposed AD 

We are proposing this AD because we 

evaluated all relevant information and 

determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. This proposed AD would 

require accomplishing the actions 

specified in the service information 

described previously, except as 

discussed under ‘‘Differences Between 

the Proposed AD and Service 

Information.’’ 

Differences Between the Proposed AD 

and Service Information 

B/E Aerospace Service Bulletin 

119003–35–5, dated April 19, 2010, 

specifies a compliance time of within 30 

days for PBE units in stock or stored as 

spares, and within the next maintenance 

check for in-service PBE units. This 

proposed AD would require compliance 

within 120 days after the effective date 

of this AD. B/E Aerospace Service 

Bulletin 119003–35–5, dated April 19, 

2010, specifies to return any faulty PBE 

units to B/E Aerospace; this proposed 

AD would not include that requirement. 

Costs of Compliance 

We estimate that this proposed AD 

would affect up to 600 aircraft of U.S. 

registry. We also estimate that it would 


erowe on DSK5CLS3C1PROD with PROPOSALS
50942 Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Proposed Rules 

take about 1 work-hour per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $0 per 

product. Based on these figures, we 

estimate the cost of this proposed AD to 

the U.S. operators to be up to $51,000, 

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 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), and 

3. 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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.
