Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes. This AD was prompted by a reported inability to extend the external handle of the emergency door from its recess due to a jammed spring mechanism. This AD requires a one-time functional check of each emergency door handle, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective June 29, 2017.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 29, 2017.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes. The NPRM published in the Federal Register on February 28, 2017 (82 FR 12074) (“the NPRM”). The NPRM was prompted by a reported inability to extend the external handle of the emergency door from its recess due to a jammed spring mechanism. The NPRM proposed to require a one-time functional check of each emergency door handle, and corrective actions if necessary. We are issuing this AD to detect and correct jamming of the door spring mechanism, which could lead to the inability to push out the emergency door external handle from its position normally aligned with the door skin. This condition could result in the inability to open the emergency door from outside during an emergency.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0051, dated March 11, 2016 (referred to after this as the Mandatory Continuing Start Printed Page 24011Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes. The MCAI states:

Failure to extend the external handle of emergency door from its recess was reported. As a consequence, it was impossible to open the rear emergency door from outside. Subsequent investigation determined that jamming of the door spring mechanism led to failure pushing out the emergency door external handle from its position normally aligned with the door skin.

This condition, if not detected and corrected, could lead to failure to open the emergency door from outside in an emergency.

To address this potential unsafe condition, Airbus Defence&Space (D&S) issued Alert Operators Transmission (AOT) AOT-CN235-52-0001 and AOT-C295-52-0001 to provide inspection instructions [and corrective actions if necessary].

For the reasons described above, this [EASA] AD requires a one-time functional check of [each of] the affected emergency door external handle[s] and, depending on findings, [detailed visual inspection for damage or unexpected material and] corrective action [repair]. This [EASA] AD also requires reporting the check result.

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-2017-0123.

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

We reviewed the following Airbus Defense and Space service information.

  • Airbus Defense and Space Alert Operators Transmission AOT-CN235-52-0001, dated September 4, 2014.
  • Airbus Defense and Space Alert Operators Transmission AOT-C295-52-0001, dated September 4, 2014.

The service information describes procedures for a one-time functional check of each emergency door handle and corrective actions if necessary. These documents are distinct since they apply to different airplane models. 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 27 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Functional Check:1 work-hour × $85 per hour = $85$0$85$2,295
Reporting1 work-hour × $85 per hour = $850852,295

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.

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.
