Airworthiness Directives; The Boeing 

Company Model 757 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Model 757 airplanes. This AD requires 

inspecting to verify the part number of 

the low-pressure flex-hoses of the 

flightcrew and supernumerary oxygen 

system installed under the oxygen mask 

stowage box at a flightcrew and 

supernumerary oxygen mask location, 

and replacing with a new nonconductive low-pressure flex-hose of the 

oxygen system if necessary. This AD 

results from reports of a low-pressure 

flex-hose of a flightcrew oxygen system 

that burned through due to inadvertent 

electrical current from a short circuit in 

an adjacent audio select panel. We are 

issuing this AD to prevent inadvertent 

electrical current, which can cause the 

low-pressure flex-hose of a flightcrew or 

supernumerary oxygen system to melt 

or burn, resulting in oxygen system 

leakage and smoke or fire. 

DATES: This AD is effective May 3, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of May 3, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Model 757 airplanes. That 

NPRM was published in the Federal 

Register on September 29, 2009 (74 FR 

49827). That NPRM proposed to require 

inspecting to verify the part number of 

the low-pressure flex-hoses of the 

flightcrew and supernumerary oxygen 

system installed under the oxygen mask 

stowage box at a flightcrew and 

supernumerary oxygen mask location, 

and replacing with a new nonconductive low-pressure flex-hose of the 

oxygen system if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received from 

the six commenters. 

Support for the NPRM 

Boeing, Air Line Pilots Association, 

International (ALPA), and the National 

Transportation Safety Board (NTSB) 

support the NPRM. 

Request To Withdraw NPRM 

American Airlines states that the 

NPRM is unnecessary and should be 

retracted. The commenter states that, 

given the Boeing compliance 

recommendation of ‘‘earliest 

opportunity when manpower, material 

and facilities are available,’’ risk analysis 

for the unsafe condition was found to be 

below the extremely improbable 

threshold. The commenter states that 

the NPRM would affect 102 of its 

airplanes, all of which have been 

modified to preclude the unsafe 

condition. The commenter also states 

that, of the 485 airplanes affected by the 

NPRM, it has mitigated the risk on 25 

percent of the U.S. fleet. The commenter 

states that the three other large U.S. 

operators have also incorporated Boeing 

Service Bulletin 757–35A0015, Revision 

2, dated June 15, 2000. The commenter 

states that this combined effort has 

substantially addressed the U.S. fleet 

and reduced the risk probabilities even 

further. The commenter also states that 

it has put procedures in place to 

preclude reintroducing the unsafe 

condition. The commenter also states 

that, since Boeing Service Bulletin 757– 

35A0015, dated September 2, 1999, was 

issued 10 years ago, the FAA appears to 

agree that at least 13 years is an 

appropriate interval of time in which 

the affected airplanes could continue to 

operate without compromising safety. 

The commenter states that the 

compliance period appears arbitrary and 

is not based on accepted risk assessment 

practices. 

We do not agree to withdraw the 

NPRM. Sufficient information exists to 

demonstrate that our risk analysis for 

the unsafe condition is adequate in 

determining the compliance times 

required in this AD. We acknowledge 

that American Airlines has been 

proactive in compliance with the 

requirements of this AD; however, not 

every operator has been quite as 

proactive. According to various bilateral 

airworthiness agreements with countries 

around the world, we are obligated to 

advise other civil airworthiness 

authorities of unsafe conditions 

identified in products manufactured in 

the United States. The issuance of ADs 

is the means by which we satisfy this 

obligation. Even if the current U.S.- 

registered fleet is in compliance with 

the requirements of the AD, the issuance 

of the rule is still necessary to ensure 

that any affected airplane imported and 

placed on the U.S. register in the future 

will be required to be in compliance as 

well. The manufacturer has advised us 

that not all of the affected airplanes 

worldwide have been modified. 

Issuance of this AD will ensure that the 

airplanes are modified before they are 

permitted to operate in the U.S. We 

have not changed the AD in this regard. 

Request To Allow a One-time Ferry 

Flight 

FedEx requests that a one-time ferry 

flight to a maintenance base be allowed 

for airplanes in a non-compliant 

configuration due to being in storage. 

FedEx states that a ferry flight would be 

required after the 36-month compliance 

date. 

We partially agree with the request for 

a one-time ferry flight. We agree with 

allowing special flight permits for the 

purpose of flying the airplane to a repair 

facility to do the work required by this 

AD. However, we disagree with revising 

this AD to specifically state that special 

flight permits are approved for this 

purpose. Special flight permits are 

currently allowed under section 39.23 of 

the Federal Aviation Regulations (14 

CFR 39.23). No change has been made 

to the AD in this regard. 

Request That Visual Inspections for the 

Part Number Not Be Required if 

Previously Done 

Northwest Airlines requests that 

visual inspections for part numbers of 

the low-pressure oxygen flex hose not 

be required if the airline has previously 

complied with Boeing Service Bulletin 

757–35A0015, Revision 2, dated June 

15, 2000. The commenter provided no 

further justification for this request. 

We agree that the visual inspection of 

the hose is not necessary if the operator 

has previously accomplished the actions 

specified in Boeing Service Bulletin 

757–35A0015, Revision 2, dated June 

15, 2000. Paragraph (f) of this AD states 

that the required actions must be done 

within the specified compliance times, 

‘‘* * * unless the actions have already 

been done.’’ This AD does not require 

that the actions be redone if they were 

done before the effective date of the AD. 

No change to the AD is necessary in this 

regard. 

Request To Reduce Proposed 

Compliance Time 

ALPA requests a shorter compliance 

time. ALPA states that the 36-month 

inspection and replacement interval is 

too long due to a high degree of risk 

imposed on passengers and crew. 

We do not agree. In developing an 

appropriate compliance time, we 

considered the safety implications, parts 

availability, and normal maintenance 

schedules for timely accomplishment of 

inspecting the low-pressure flex-hoses 

of the flightcrew and supernumerary 

oxygen system. Further, we arrived at 

the proposed compliance time with 

operator and manufacturer concurrence. 

In consideration of all of these factors, 

we determined that the compliance 

time, as proposed, represents an 

appropriate interval in which the 

inspection and replacement can be 

accomplished in a timely manner 

within the fleet, while still maintaining 

an adequate level of safety. Operators 

are always permitted to accomplish the 

requirements of an AD at a time earlier 

than the specified compliance time; 

therefore, an operator may choose to 

replace the oxygen hose before 36 

months after the effective date of this 

AD in order to accomplish the 

requirements of this AD. If additional 

data are presented that would justify a 

shorter compliance time, we might 

consider further rulemaking on this 

issue. We have not changed the AD in 

this regard. 


PWALKER on DSK8KYBLC1PROD with RULES
15330 Federal Register / Vol. 75, No. 59 / Monday, March 29, 2010 / Rules and Regulations 

Request To Revise Applicability To 

Include Manufacturers of Other 

Airplanes With Similar Low-Pressure 

Oxygen Hoses 

Although the NTSB fully supports the 

NPRM, the NTSB states that because the 

risk of fire from electrically conductive 

hoses is not restricted to Boeing models, 

the FAA should widen the inspection 

and replacement of oxygen hoses 

beyond the airplanes cited in the NPRM. 

The NTSB notes that the NPRM and the 

future rules mentioned in the NPRM 

would apply only to Boeing airplanes. 

The NTSB states that suppliers provide 

other airplane manufacturers with lowpressure oxygen hoses that are nearly 

identical to those that the NPRM seeks 

to identify and replace. 

From these statements, we infer the 

NTSB is requesting that we revise the 

NPRM to add other airplane models to 

the applicability of the NPRM. We agree 

that suspect low-pressure oxygen hoses 

or similar hoses might be installed on 

airplane models produced by 

manufacturers other than Boeing. 

Determining whether an unsafe 

condition exists on these other airplanes 

is outside the scope of this AD. We will 

continue to evaluate the safety 

implications of these oxygen hoses as 

they apply to other manufacturers and 

initiate additional rulemaking to 

address the unsafe condition on those 

airplanes if necessary. We have not 

changed the AD in this regard. 

Request To Remove Requirement for 

Recording Part Numbers 

Northwest Airlines requests that we 

remove the proposed requirement to 

record the part number of the flex hose 

that is intended for replacement. 

Northwest Airlines states that once an 

oxygen hose has been identified as 

affected by the visual inspection 

confirming the part number, the affected 

hose will be replaced. Northwest 

Airlines states that there is no further 

instruction on where to record this 

information or what to do with it. 

Northwest Airlines states that requiring 

the recording of the part number of the 

affected oxygen hose does not provide 

any benefit or enhance safety. 

We agree that recording the part 

number of the affected hose does not 

serve any safety interest. Recording the 

part number of the affected hose 

identified for replacement as specified 

in Boeing Service Bulletin 757– 

35A0015, Revision 2, dated June 15, 

2000, is not necessary for compliance 

with this AD. We have revised 

paragraph (g)(1) of this AD to clarify that 

recording the part number of the 

affected oxygen hose is not necessary. 

Explanation of Changes Made to This 

AD 

We have revised this AD to identify 

the legal name of the manufacturer as 

published in the most recent type 

certificate data sheet for the affected 

airplane models. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

the AD. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the NPRM, we have 

increased the labor rate used in the 

Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of 

Compliance information, below, reflects 

this increase in the specified hourly 

labor rate. 

Costs of Compliance 

We estimate that this AD would affect 

485 airplanes of U.S. registry. We also 

estimate that it would take 1 work-hour 

per product to comply with this AD. 

The average labor rate is $85 per workhour. Based on these figures, we 

estimate the cost of this proposed AD to 

the U.S. operators to be $41,225, 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 

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 

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.

Unsafe Condition 

(e) This AD results from reports of a lowpressure flex-hose of a flightcrew oxygen 

system that burned through due to 

inadvertent electrical current from a short 

circuit in an adjacent audio select panel. We 

are issuing this AD to prevent inadvertent 

electrical current which can cause the lowpressure flex-hoses used in the flightcrew 

and supernumerary oxygen system to melt or 

burn, resulting in oxygen system leakage and 

smoke or fire. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Inspection 

(g) Within 36 months after the effective 

date of this AD, inspect to determine whether 

any low-pressure flex-hose of the flightcrew 

and supernumerary oxygen systems installed 

under the oxygen mask stowage location has 

a part number identified in Table 2 of this 

AD. A review of airplane maintenance 

records is acceptable in lieu of this 

inspection if the part number of the lowpressure flex-hoses of the flightcrew and 

supernumerary oxygen system can be 

conclusively determined from that review. 

(1) For any low-pressure flex-hose having 

a part number identified in Table 2 of this 

AD, before further flight, replace the hose 

with a new or serviceable part, in accordance 

with the Accomplishment Instructions of the
