FAA AD Differences 

(f) This AD differs from the Mandatory 

Continuing Airworthiness Information 

(MCAI) and/or service information as 

follows: 

(1) We reduced the initial compliance time 

for TAE 125–02–99 reciprocating engines 

from within 110 flight hours to within 100 

flight hours, and for TAE 125–01 

reciprocating engines from within the next 3 

months to within 100 flight hours. 

(2) We require a repetitive replacement 

compliance time for the rail pressure control 

valve of within every 600 flight hours. The 

MCAIs instruct the operators to follow 

Thielert Maintenance Manual, Chapter 5, 

Airworthiness Limitations, for the repetitive 

compliance time. 

(3) We exclude the repetitive inspections of 

the alternator on TAE 125–01 engines, as we 

consider these inspections as maintenance 

actions. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 3, 2009.

address MCAI originated by aviation 

authorities of other countries to provide 

adequate time for interested parties to 

submit comments. The comment period 

for these proposed ADs is now typically 

45 days, which is consistent with the 

comment period for domestic transport

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2009–0077, 

dated April 6, 2009 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

For the reasons described above, this AD 

requires the modification of the hat rack 

connectors on stow, and the rerouting of the 

associated wire harness in case of monument 

installed in door 2 area. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletins A330–92–3070, Revision 01, 

dated January 12, 2009; and A340–92– 

4073, Revision 01, dated January 13, 

2009. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 proposed 

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 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 43 products of U.S. registry. 

We also estimate that it would take 

about 3 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. Required 

parts costs are negligible. Where the 

service information lists required parts 

costs that are uncovered under 

warranty, we have assumed that there 

will be no charge for these costs. 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 

the proposed AD on U.S. operators to be 

$10,320, or $240 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

serial numbers on which Airbus modification 

48825 has been embodied in production, 

except those on which Airbus modification 

57409 has been embodied in production. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 92. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

For the reasons described above, this AD 

requires the modification of the hat rack 

connectors on stow, and the rerouting of the 

associated wire harness in case of monument 

installed in door 2 area. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 24 months after the effective

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Boeing Model 737–600, –700, –700C, 

–800, and –900 series airplanes. This 

proposed AD would require inspections 

for scribe lines in the fuselage skin at 

lap joints, the splice strap at certain butt 

joints, the skin or doubler at certain 

approved repair doublers, and the skin 

at decal locations; and related 

investigative and corrective actions if 

necessary. This proposed AD results 

from reports of scribe line damage found 

adjacent to the skin lap joints, decals, 

and wing-to-body fairings. We are 

proposing this AD to detect and correct 

scribe lines, which can develop into 

fatigue cracks in the skin. Undetected 

fatigue cracks can grow and cause 

sudden decompression of the airplane. 

DATES: We must receive comments on 

this proposed AD by December 3, 2009.
