AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2015-23-13, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-23-13 currently requires modification of the pin programming of the flight warning computer (FWC) to activate the stop rudder input warning (SRIW) logic; and an inspection to determine the part numbers of the FWC and the flight augmentation computer (FAC), and replacement of the FWC and FAC if necessary. Since we issued AD 2015-23-13, we have determined that, for certain airplanes, additional modification instructions must be accomplished to allow installation of the minimum FWC and FAC configuration compatible with SRIW activation. This proposed AD would, for certain airplanes, also require accomplishment of additional modification instructions to install the minimum FWC and FAC configuration compatible with SRIW activation. We are proposing this AD to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by April 3, 2017.

Discussion

On November 9, 2015, we issued AD 2015-23-13, Amendment 39-18330 (80 FR 73099, November 24, 2015) (“AD 2015-23-13”), for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-23-13 was prompted by a determination that, in specific flight conditions, the allowable load limits on the vertical tail plane could be reached and possibly exceeded. Exceeding allowable load limits could result in detachment of the vertical tail plane. AD 2015-23-13 requires modification of the pin programming of the FWC to activate the SRIW logic; an inspection to determine the part numbers of the FWC and the FAC, and replacement of the FWC and FAC if necessary. We issued AD 2015-23-13 to prevent detachment of the vertical tail plane and consequent loss of control of the airplane.

Since we issued AD 2015-23-13, we have determined that, for certain airplanes, additional modification instructions must be accomplished to allow installation of the minimum FWC and FAC configuration compatible with SRIW activation.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0132, dated July 5, 2016; corrected July 20, 2016 (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:

During design reviews that were conducted following safety recommendations related to in-service incidents and one accident on another aircraft type, it has been determined that, in specific flight conditions, the allowable load limits on the vertical tail Start Printed Page 10722plane could be reached and possibly exceeded.

This condition, if not corrected, could lead to in-flight detachment of the vertical tail plane, possibly resulting in loss of control of the aeroplane.

To address this unsafe condition, Airbus developed modifications within the flight augmentation computer (FAC) to reduce the vertical tail plane stress and to activate a conditional aural warning within the flight warning computer (FWC) to further protect against pilot induced rudder doublets.

Consequently, EASA issued AD 2014-0217 (later revised) [which corresponds to FAA AD 2015-23-13] to require installation and activation of the stop rudder input warning (SRIW) logic. In addition, that [EASA] AD required upgrades of the FAC and FWC, to introduce the SRIW logic and SRIW aural capability, respectively. After modification, the [EASA] AD prohibited (re)installation of certain Part Number (P/N) FWC and FAC.

Since EASA AD 2014-0217R1 was issued, Airbus made available additional modification instructions that, for certain aeroplanes, must be accomplished to allow installation of the minimum FWC and FAC configuration compatible with SRIW activation.

For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2014-0217R1, which is superseded, and includes reference to modification instructions, which must be accomplished on certain aeroplanes.

This [EASA] AD is republished to remove a typographical error in Appendix 1 [of the EASA AD].

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-2016-9573.

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 these same type designs.

Costs of Compliance

We estimate that this proposed AD affects 1,032 airplanes of U.S. registry.

The actions required by AD 2015-23-13, and retained in this proposed AD take about 3 work-hours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2015-23-13 is $255 per product.

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 $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $263,160, or $255 per product.

In addition, we estimate that any necessary follow-on actions will take about 6 work-hours (3 work-hours for an FWC and 3 work-hours for an FAC), and require parts costing $88,000 (FAC), for a cost of $88,510 per product. We have no way of determining the number of aircraft that might 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 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);

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.
