2016-19486. Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2003-25-07 for certain Airbus Model A319 and A320 series airplanes, and AD 2005-13-39 for certain Airbus Model A321 series airplanes. AD 2003-25-07 required a revision to the airplane flight manual (AFM) and replacement of both elevator aileron computers (ELACs) having L80 standards with new ELACs having L81 standards. AD 2005-13-39 required a revision to the AFM, replacement of existing ELACs with ELACs having L83 or L91 standards, as applicable; and a concurrent action. Since we issued AD 2003-25-07 and AD 2005-13-39, we have determined that new ELAC standards must be incorporated. The ELAC standards have been upgraded to version L97+, which implements enhanced angle-of-attack (AOA) monitoring to better detect AOA blockage, including multiple AOA blockages. This AD requires replacing existing ELACs with new ELACs having L97+ standards or revising the software in an existing ELAC to the L97+ standards, as applicable, which terminates the requirements of AD 2003-25-07 and AD 2005-13-39. This AD also expands the applicability to include all Airbus Model A318, A319, A320, and A321 series airplanes. We are issuing this AD to prevent inadvertent activation of the AOA protections. Inadvertent activation of the AOA protections could result in a continuous nose-down pitch rate that could result in reduced controllability of the airplane.

DATES:

This AD is effective September 23, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 23, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 9, 2005 (70 FR 38580, July 5, 2005).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2003-25-07, Amendment 39-13390 (68 FR 70431, December 18, 2003) (“AD 2003-25-07”); and AD 2005-13-39, Amendment 39-14176 (70 FR 38580, July 5, 2005) (“AD 2005-13-39”).

AD 2003-25-07 applied to certain Airbus Model A319 and A320 series airplanes, and AD 2005-13-39 applied to certain Airbus Model A321 series airplanes. The NPRM published in the Federal Register on March 17, 2016 (81 FR 14404). The NPRM was prompted by a determination that new ELAC standards must be incorporated. The ELAC standards have been upgraded to version L97+, which implements enhanced AOA monitoring to better detect AOA blockage, including multiple AOA blockages.

The NPRM proposed to require replacing existing ELACs with new ELACs having L97+ standards or revising the software in an existing ELAC to the L97+ standards, as applicable, which would terminate the requirements of AD 2003-25-07 and AD 2005-13-39. We are issuing this AD to prevent inadvertent activation of the AOA protections. Inadvertent activation of the AOA protections could result in a continuous nose-down pitch rate that could result in reduced controllability of the airplane.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0088R1, including Appendix 01, dated June 2, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus Model A318, A319, A320, and A321 series airplanes. The MCAI states:

The latest elevator aileron computer (ELAC) standard, L97+, implements enhanced Angle of Attack (AOA) monitoring in order to better detect cases of AOA blockage, including multiple AOA blockage.

Two ELAC L97+ versions are currently available, Part Number (P/N) 3945129109 with data loading capability, and P/N 3945128215 without the data loading capability. Three existing [EASA] ADs requiring installation of earlier ELAC (software) have been identified and taken into account for cancellation by this new [EASA] AD.

For the reasons described above, EASA issued AD 2015-0088, cancelling DGAC [Direction Générale de l'Aviation Civile] France AD 95-203-072 (no requirements retained) [which corresponds to FAA AD 98-09-18, Amendment 39-10499 (63 FR 23374, April 29, 1998)], and partially retaining the requirements of DGAC France AD 2001-508 [which corresponds to FAA AD 2003-25-07], and [DGAC France] AD F-2004-147 (EASA approval ref. 2004-8601) [which corresponds to FAA AD 2005-13-39], which were superseded, and to require replacement of all ELAC with ELAC L97+ standard.

Since that [EASA] AD was issued, some errors were detected in Appendix 1 of the [EASA] AD, and one P/N ELAC was inadvertently omitted. This [EASA] AD revises EASA AD 2015-0088 to correct these errors and to add clarification to paragraph (7) [of the EASA AD].

The required actions include either replacing existing ELACs with new ELACs having L97+ standards uploaded, or revising the software in the existing ELACs to L97+ standards. This AD also expands the applicability to include all Airbus Model A318, A319, A320, and A321 series airplanes. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-4226.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comment received. The commenter supported the NPRM.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A320-27-1243, including Appendix 01, dated March 17, 2015. This service information describes procedures for replacing the existing ELACs with new ELACs having L97+ standards, and modifying existing ELACs into units with L97+ standards.

Airbus has also issued Service Bulletin A320-27-1244, dated March 5, 2015. This service information describes procedures for modification of an airplane by replacing any existing ELAC unit with an ELAC 97+ unit having P/N 3945128215.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

We estimate that this AD affects 940 airplanes of U.S. registry.

The actions required by AD 2003-25-07 and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2003-25-07 is $85 per product.

The actions required by AD 2005-13-39 and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2005-13-39 is $85 per product.

We also estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $7,230 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $7,035,900, or $7,485 per product.

According to the parts manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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 that this AD:

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.
