Airworthiness Directives; Airbus Model 

A330–200 and A330–300 Series 

Airplanes 

AGENCY: Federal Aviation 

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: An A330 experienced an 

uncommanded engine #1 in flight spool 

down, which occurred while applying 

fuel gravity feed procedure, in response 

to low pressure indications from all fuel 

boost pumps, in both left and right 

wings. The investigations revealed that 

the wing tank pressure switches P/N 

(part number) HTE69000–1 had frozen 

due to water accumulated in their 

external part, causing spurious low 

pressure indications. As per procedure, 

the main pumps are then switched off, 

increasing the level of unavailable fuel. 

This, in combination with very low fuel 

quantities or another independent 

trapped fuel failure scenarios, can lead 

to fuel starvation on the affected 

engine(s). 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 August 27, 2010.

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 2010–0018, 

dated February 4, 2010 (referred to after 

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

condition for the specified products. 

The MCAI states: 

An A330 experienced an uncommanded 

engine #1 in flight spool down, which 

occurred while applying fuel gravity feed 

procedure, in response to low pressure 

indications from all fuel boost pumps, in 

both left and right wings. 

The investigations revealed that the wing 

tank pressure switches P/N (part number) 

HTE69000–1 had frozen due to water 

accumulated in their external part, causing 

spurious low pressure indications. 

As per procedure, the main pumps are then 

switched off, increasing the level of 

unavailable fuel. This, in combination with 

very low fuel quantities or another 

independent trapped fuel failure scenarios, 

can lead to fuel starvation on the affected 

engine(s). This condition, if not corrected, 

could lead to a potential unsafe condition. 

This AD requires the replacement of all 

four wing tank fuel pressure switches 

associated to main pumps by new ones with 

a more robust design preventing water 

accumulation and freezing. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus issued Mandatory Service 

Bulletin A330–28–3111, Revision 02, 

dated March 24, 2010. 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 


jlentini on DSKJ8SOYB1PROD with PROPOSALS
39870 Federal Register / Vol. 75, No. 133 / Tuesday, July 13, 2010 / Proposed Rules 

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 48 products of U.S. registry. 

We also estimate that it would take 

about 7 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Where the service information lists 

required parts costs that are covered 

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 $28,560, or $595 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

Airbus: Docket No. FAA–2010–0697; 

Directorate Identifier 2010–NM–102–AD. 

Comments Due Date 

(a) We must receive comments by August 

27, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A330– 

201, –202, –203, –223, –243, –301, –302, 

–303, –321, –322, –323, –341, –342, and –343 

airplanes, certificated in any category, all 

manufacturer serial numbers, equipped with 

part number (P/N) HTE69000–1 wing tank 

pressure switches installed at Functional 

Item Number (FIN) locations 74QA1, 74QA2, 

75QA1 or 75QA2. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

An A330 experienced an uncommanded 

engine #1 in flight spool down, which 

occurred while applying fuel gravity feed 

procedure, in response to low pressure 

indications from all fuel boost pumps, in 

both left and right wings. 

The investigations revealed that the wing 

tank pressure switches P/N HTE69000–1 had 

frozen due to water accumulated in their 

external part, causing spurious low pressure 

indications. 

As per procedure, the main pumps are then 

switched off, increasing the level of 

unavailable fuel. This, in combination with 

very low fuel quantities or another 

independent trapped fuel failure scenarios, 

can lead to fuel starvation on the affected 

engine(s).

(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. 

Actions 

(g) Within 5 years after the effective date 

of this AD, replace the wing tank main pump 

pressure switches having P/N HTE69000–1 

in accordance with the Accomplishment 

Instructions of Airbus Mandatory Service 

Bulletin A330–28–3111, Revision 02, dated 

March 24, 2010. 

(h) Actions accomplished before the 

effective date of this AD according to Airbus 

Mandatory Service Bulletin A330–28–3111, 

dated August 12, 2009; or Revision 01, dated 

December 4, 2009; are considered acceptable 

for compliance with the corresponding 

actions specified in this AD.

SUPPLEMENTARY INFORMATION: 

I. Background 

The National Manufactured Housing 

Construction and Safety Standards Act 

of 1974 (42 U.S.C. 5401–5426) (the Act) 

authorizes HUD to establish and amend 

the Federal Manufactured Home 

Construction and Safety Standards (the 

Construction and Safety Standards, or 

Standards) codified in 24 CFR part 

3280. The Act was amended in 2000 by 

the Manufactured Housing 

Improvement Act of 2000 (Pub. L. 106– 

569), by expanding its purposes and 

creating the Manufactured Housing 

Consensus Committee (MHCC). 

As amended, the purposes of the Act 

(enumerated at 42 U.S.C. 5401) are: ‘‘(1) 

to protect the quality, durability, safety, 

and affordability of manufactured 

homes; (2) to facilitate the availability of 

affordable manufactured homes and to 

increase homeownership for all 

Americans; (3) to provide for the 

establishment of practical, uniform, and, 

to the extent possible, performancebased Federal construction standards for 

manufactured homes; (4) to encourage 

innovative and cost-effective 

construction techniques for 

manufactured homes; (5) to protect 

residents of manufactured homes with 

respect to personal injuries and the 

amount of insurance costs and property 

damages in manufactured housing 

consistent with the other purposes of 

this section; (6) to establish a balanced 

consensus process for the development, 

revision, and interpretation of Federal 

construction and safety standards for 

manufactured homes and related 

regulations for the enforcement of such 

standards; (7) to ensure uniform and 

effective enforcement of Federal 

construction and safety standards for 

manufactured homes; and (8) to ensure 

that the public interest in, and need for, 

affordable manufactured housing is duly 

considered in all determinations 

relating to the Federal standards and 

their enforcement.’’ 

In addition, the amended Act 

generally requires HUD to establish 

Construction and Safety Standards that 

are reasonable and practical, meet high 

standards of protection, are 

performance-based, and are objectively 

stated. Congress specifically established 

the MHCC to develop proposed 

revisions to the Construction and Safety 

Standards. The Act provides specific 

procedures (42 U.S.C. 5403) for the 

MHCC process.
