Subject 

(d) Air Transport Association (ATA) of 

America Code 35: Oxygen. 

Unsafe Condition 

(e) This AD results from a report of a lowpressure flex-hose of the 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 systems 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, do an inspection to 

determine whether any low-pressure flexhose of the flightcrew and supernumerary 

oxygen systems installed under the oxygen 

mask stowage location has a part number 

identified in Table 1 of this AD. A review of 

airplane maintenance records is acceptable in 

lieu of this inspection if the part number of 

the low-pressure flex-hoses of the flightcrew 

and supernumerary oxygen systems can be 

conclusively determined from that review. 

(1) For any hose having a part number 

identified in Table 1 of this AD, before 

further flight, replace the hose with a new or 

serviceable part, in accordance with the 

Accomplishment Instructions of Boeing 

Service Bulletin 767–35A0034, Revision 1, 

dated June 22, 2000. 

(2) For any hose not having a part number 

identified in Table 1 of this AD, no further 

action is required by this paragraph.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During an annual inspection, a water 

ballast hose connector was found 

disconnected from the fuselage wall of an 

Astir CS. 

The investigation has shown that the hosefuselage connection bonding has been 

degraded over years of service. 

This condition, if not corrected, could lead 

to the following consequences:

—The water contained in the wing tanks 

could run down into the fuselage and 

fuselage tail which could cause a 

displacement of the sailplane centre of 

gravity and consequently may lead to the 

loss of the sailplane controllability, or/and 

—The loosened hose may jam the flight 

controls (push rods) and consequently may 

lead to the loss of the sailplane 

controllability. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

September 9, 2010. 

On September 9, 2010, 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 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on May 3, 2010 (75 FR 23194). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

During an annual inspection, a water 

ballast hose connector was found 

disconnected from the fuselage wall of an 

Astir CS. 

The investigation has shown that the hosefuselage connection bonding has been 

degraded over years of service. 

This condition, if not corrected, could lead 

to the following consequences: 

—The water contained in the wing tanks 

could run down into the fuselage and 

fuselage tail which could cause a 

displacement of the sailplane centre of 

gravity and consequently may lead to the 

loss of the sailplane controllability, or/and 

—The loosened hose may jam the flight 

controls (push rods) and consequently may 

lead to the loss of the sailplane 

controllability. 

For the reason stated above, the original 

issue of this AD required the inspection of 

the waterballast system hose-fuselage 

connections and the accomplishment of the 

relevant corrective actions (repair) as 

necessary. 

This AD is revised to clarify the purpose 

of the insertion of the repetitive inspection in 

the Aircraft Maintenance Programme and to 

refer to a more appropriate scheduled 

maintenance review for the insertion of the 

repetitive inspection in the Aircraft 

Maintenance Programme. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM 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. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

113 products of U.S. registry. We also 

estimate that it will take about 1 workhour 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 $9,605 or $85 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $5, for a cost of $90 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 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. 

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 Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During an annual inspection, a water 

ballast hose connector was found 

disconnected from the fuselage wall of an 

Astir CS. 

The investigation has shown that the hosefuselage connection bonding has been 

degraded over years of service. 

This condition, if not corrected, could lead 

to the following consequences: 

—The water contained in the wing tanks 

could run down into the fuselage and 

fuselage tail which could cause a 

displacement of the sailplane centre of 

gravity and consequently may lead to the 

loss of the sailplane controllability, or/and 

—The loosened hose may jam the flight 

controls (push rods) and consequently may 

lead to the loss of the sailplane 

controllability. 

For the reason stated above, the original 

issue of this AD required the inspection of 

the waterballast system hose-fuselage 

connections and the accomplishment of the 

relevant corrective actions (repair) as 

necessary. 

This AD is revised to clarify the purpose 

of the insertion of the repetitive inspection in 

the Aircraft Maintenance Programme and to 

refer to a more appropriate scheduled 

maintenance review for the insertion of the 

repetitive inspection in the Aircraft 

Maintenance Programme.
