2016-07572. Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes  

  • Start Preamble

    AGENCY:

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

    ACTION:

    Final rule.

    SUMMARY:

    We are adopting a new airworthiness directive (AD) for certain Airbus Defense and Space S.A. Model CN-235-200 and CN-235-300 airplanes. This AD was prompted by reports of false engine fire warning events, which consequently led to engine in-flight shutdowns. This AD requires modification of the location and routing of the engine fire detection system. We are issuing this AD to prevent unnecessary engine in-flight shutdown, which could result in reduced controllability of the airplane.

    DATES:

    This AD becomes effective May 16, 2016.

    The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 16, 2016.

    SUPPLEMENTARY INFORMATION:

    Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Defense and Space S.A. Model CN-235-200 and CN-235-300 airplanes. The NPRM published in the Federal Register on November 12, 2015 (80 FR 69898) (“the NPRM”). The NPRM was prompted by reports of false engine fire warning events, which consequently led to engine in-flight shutdowns. The NPRM proposed to require modification of the location and routing of the engine fire detection system. We are issuing this AD to prevent unnecessary engine in-flight shutdown, which 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 2015-0011, dated January 20, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Defense and Space S.A. Model CN-235-200 and CN-235-300 airplanes. The MCAI states:

    Several cases of false engine fire warning events were reported, which consequently led to engine in-flight shut down (IFSD) executed by the flightcrew using the appropriate emergency procedures. Subsequent investigation determined that these false engine fire warnings were the result of insufficient insulation capability of the engine fire detection system. This allowed penetration of moisture into the fire detector connectors, reducing the insulation resistance between the inner electrode and connector housing below the required values.

    This condition, if not corrected, could lead to further cases of unnecessary engine IFSD, possibly resulting in reduced control of the aeroplane.

    To address this potential unsafe condition, EADS-CASA issued Service Bulletin (SB) SB235-26-0006 providing modification instructions.

    For the reasons described above, this [EASA] AD requires modification of the location and routing of the engine fire detection system.

    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-2015-4809.

    Comments

    We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

    Conclusion

    We reviewed the relevant data 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

    EADS CASA has issued Service Bulletin SB-235-26-0006, dated July 8, 2014. The service information describes procedures for modifying the engine fire detection system. This service Start Printed Page 21241information 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 24 airplanes of U.S. registry.

    We also estimate that it will take about 75 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 $1,577 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $190,848, or $7,952 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 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.
