ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200 and A340-300 series airplanes. This proposed AD was prompted by reports of an elevator blocked in the down position due to two independent failures; first, the inability of a servo control to switch to active mode because it was not detected by a flight control computer, and second, an internal hydraulic leak due to the deterioration of an O-ring seal on a solenoid. This proposed AD would require, depending on airplane configuration, modifying three flight control primary computers (FCPCs); modifying two flight control secondary computers (FCSCs); revising the airplane flight manual (AFM) to include certain information; replacing certain O-rings; and checking part number, and replacing certain O-ring seals if needed. We are proposing this AD to detect and correct O-rings with incorrect part number whose deterioration could lead to improper sealing of solenoid valves, and to correct FCPC and FCSC software to allow better control of elevator positioning; both conditions, if not corrected, could lead to the loss of elevator control on takeoff, and potentially reduce the controllability of the airplane.

DATES:

We must receive comments on this proposed AD by September 28, 2012.

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 2010-0081, dated April 27, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

This [EASA] AD deals with the two following points:

  • Case of an elevator blocked in down position due to two independent failures one of which is hidden:

Each elevator is controlled by two servo controls. In normal operation:

—One servo control in active mode controlled by PRIM 1 (Green servo control),

—One servo control in damping mode (Yellow or Blue servo control) monitored by PRIM 2.

Change from active mode to damped mode is obtained by means of a mode selector which is controlled by two identical solenoid valves housed on the servo control. The sealing of each solenoid valve is ensured by four O-ring seals.

During pre-flight control checks, the flight crew of an A330-200 aeroplane observed that one of the elevators was blocked in down position, the ECAM screen displaying “F/CTL PRIM 1 PITCH FAULT”.

This condition was due to two independent failures, one of which was dormant, which occurred on one of the elevators.

Investigations revealed that the origin of the elevator malfunction was due to the inability of the Yellow servo control to switch to active mode.

This inability:

—Was caused by an internal hydraulic leak due to the deterioration of an O-ring seal on a solenoid valve,

—Was not detected by the PRIM 2 computer nor announced to the flight crew.

  • Incorrect Part Number (P/N) for solenoid valve O-ring seals in IPC [illustrated parts catalog]:

An incorrect O-ring seal P/N in IPC 27-34-51-1 could have led to the installation of O-ring seals incompatible with the hydraulic fluid, causing them to deteriorate.

These conditions if not detected could lead to the loss of elevator [control] on takeoff and, potentially reduce the controllability of the aeroplane.

The aim of EASA AD 2007-0009 was to:

—Take over the requirements of AD F-2004-158, and

—Require the terminating action for § (1), (2) and (4) of this AD by introducing new capped seals on solenoid valves for A330-200 only.

This new [EASA] AD * * * requires the embodiment of the latest software standard on the three Flight Control Primary Computers (FCPC) and on the two Flight Control Secondary Computers (FCSC) [by modifying the FCPCs and FCSCs] * * *.

The modification is accomplished either by replacing the FCPCs and FCSCs with new FCPCs and FCSCs, or by replacing or reprogramming the on-board replaceable modules in the FCPCs and FCSCs. Required actions also include, depending on airplane configuration, the following actions: revising the airplane flight manual (AFM) to include certain information; replacing certain O-rings; and checking part number, and replacing certain O-ring seals if needed. You may obtain further information by examining the MCAI in the AD docket.

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

EASA AD 2010-0081, dated April 27, 2010, contains additional requirements to modify the four elevator servo controls installed on Model A330-200 series airplanes, as specified in Airbus Service Bulletin A330-27-3134. This AD does not contain those requirements because those actions are already mandated by FAA AD 2008-06-07, Amendment 39-15419 (73 FR 13103, March 12, 2008; as corrected on April 15, 2008 (73 FR 20367), and must be accomplished within 17 months after April 16, 2008 (the effective date of AD 2008-06-07, Amendment 39-15419). EASA AD 2010-0081, dated April 27, 2010, also contains additional requirements to amend the airplane flight manual to include the operational procedure specified in paragraph (n) of this proposed AD. This proposed AD does not include that requirement, because that information is already contained in the U.S. operators' AFMs.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 41 products of U.S. registry. We also estimate that it would take about 5 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 $17,425, or $425 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 that 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);

3. Will not affect intrastate aviation in Alaska; and

4. 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.

List of Subjects in 14 CFR Part 39

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
