Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2008-19-08, for all Dassault Aviation Model Falcon 10 airplanes. AD 2008-19-08 required repetitive replacement of the flexible hoses installed in the wing (slat) anti-icing system with new hoses. This new AD requires reducing the life limit of these flexible hoses, which reduces the repetitive replacement intervals. This AD was prompted by additional reports of collapse of the flexible hoses installed in the slat anti-icing systems on airplanes equipped with new, improved hoses. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.

DATES:

This AD is effective October 21, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 11, 2007 (72 FR 51161, September 6, 2007).

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008-19-08, Amendment 39-15675 (73 FR 54492, September 22, 2008) (“AD 2008-19-08”). AD 2008-19-08 applied to all Dassault Aviation Model Falcon 10 airplanes. The NPRM published in the Federal Register on May 3, 2016 (81 FR 26495) (“the NPRM”). The NPRM was prompted by additional reports of collapse of the flexible hoses installed in the slat anti-icing systems on airplanes equipped with new, improved hoses. The NPRM proposed to continue to require repetitive replacement of the flexible hoses installed in the wing (slat) anti-icing system with new hoses. The NPRM also proposed to require reducing the life limit of these flexible hoses, which would reduce the repetitive replacement intervals. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, 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 2014-0104, dated May 7, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition on all Dassault Aviation Model Falcon 10 airplanes. The MCAI states:

Occurrences were reported involving an in-service Falcon 10 aeroplane, where wing anti-ice hoses collapsed. The subsequent investigation revealed that the flexible hose, Part Number (P/N) FAL1005, collapsed because of an internal ply separation.

This condition, if not corrected, could lead to failure of the ice-protection system to remove ice accretion on the wing, possibly resulting in reduced control of the aeroplane.

To address this potential unsafe condition, EASA issued AD 2005-0020 and AD 2006-0114 [which correspond to AD 2008-19-08], respectively, imposing flight limitations and requiring replacement of the flexible hosesP/N FAL1005 with improved hoses P/N FAL1007.

Since those [EASA] ADs were issued, further occurrences were reported concerning aeroplanes with improved hoses, which led to the conclusion that the life limit of the flexible hose P/N FAL1007 must be reduced.

For the reasons above, this [EASA] AD retains the requirements of EASA AD 2006-0114, which is superseded; supersedes EASA AD 2005-0020; requires replacement of flexible hoses having P/N FAL 1000, P/N 1001, P/N FAL1005, or P/N FAL1005D, and reduces the life limit of the flexible hosesP/N 1007 [which would reduce the repetitive replacement intervals].

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-2016-6146.

Comments

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

Clarification to This AD

We have changed the “Definition of Serviceable Flexible Hose” specified in paragraph (j) of this AD from “350 flight hours or less” to “less than 350 flight hours” to clarify the intent of the flight hours for the life-limit of the flexible hose specified in paragraph (i) of this AD.

We have also revised paragraph (g) of this AD to clarify that accomplishing the replacement required by paragraph (i) of this AD terminates the replacements required by paragraph (g) of this AD.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously, and 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.

Costs of Compliance

We estimate that this AD affects 124 airplanes of U.S. registry.

The actions that are required by AD 2008-19-08, and retained in this AD, take about 8 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $880. Based on these figures, the estimated cost of the actions that are required by AD 2008-19-08 is up to $1,560 per product, per replacement cycle.

We also estimate that it takes about 4 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $936 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $158,224, or $1,276 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, Start Printed Page 63690or 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.
