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 Bombardier, Inc. Model BD-700-1A11 airplanes. This AD was prompted by a report that certain lanyards for the passenger oxygen masks are longer than the specified length, possibly leading to inactive oxygen masks in an emergency. This AD requires replacement of certain oxygen mask lanyards. We are issuing this AD to detect and correct lanyards of incorrect length, which might not activate the flow of oxygen in an emergency, resulting in injury to passengers.

DATES:

This AD becomes effective December 2, 2014.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 2, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model BD-700-1A11 airplanes. The SNPRM published in the Federal Register on July 23, 2014 (79 FR 42708). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on July 18, 2013 (78 FR 42893).

Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF-2012-31R1, dated September 17, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Bombardier, Inc. Model BD-700-1A11 airplanes. The MCAI states:

The aeroplane manufacturer has determined that the Oxygen Dispensing Unit (ODU) lanyards, in several locations throughout the aeroplane cabin, are excessively long. In an emergency situation where oxygen is required, it is possible that certain occupants may put their oxygen mask on without automatically activating the oxygen flow which could result in a fatal injury.

The original issue of this [Canadian] AD mandated the replacement of the existing ODU lanyards with lanyards of the correct length.

After the issuance of the original [Canadian] AD, the aeroplane manufacturer discovered that operators had not replaced all of the affected ODU lanyards due to misinterpretation of the accomplishment instructions of the Basic Issue of SB 700-1A11-35-009. Revision 1 of this [Canadian] AD is issued to mandate the incorporation of the revised SB with clarified accomplishment instructions.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/​#!documentDetail;​D=​FAA-2013-0548-0004.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (79 FR 42708, July 23, 2014) 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 SNPRM (79 FR 42708, July 23, 2014) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the SNPRM (79 FR 42708, July 23, 2014).

Costs of Compliance

We estimate that this AD affects 22 airplanes of U.S. registry.

We also estimate that it will take about 16 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 $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $29,920, or $1,360 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.
