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 Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This AD was prompted by reports of failures of the emergency slide on the forward passenger door, which prevented the door from opening. This AD requires repetitive re-packing of certain forward door escape slides. We are issuing this AD to prevent failure of the emergency slide, which can prevent the forward passenger door from opening, and which could result in impeded emergency evacuation and possible subsequent injury to passengers and flightcrew.

DATES:

This AD becomes effective February 10, 2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 10, 2014.

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 the specified products. The NPRM was published in the Federal Register on October 25, 2012 (77 FR 65144). The NPRM proposed to correct an unsafe condition for the specified products. The Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directives 2011-12-01 and 2011-12-02, both effective December 27, 2011 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for the specified products. MCAI Brazilian Airworthiness Directive 2011-12-01 states:

During operational checks of escape slide P/N [part number] 4A4030-5, some operators have reported failure in the escape slide preventing the forward passenger door opening. This [Brazilian] AD is being issued to prevent failure of this system which could impede an emergency evacuation and increase the chance of injury to passengers and flight crew.

* * * * *

MCAI Brazilian Airworthiness Directive 2011-12-02 states:

During scheduled deployment tests of escape slide P/N 104003-2, some operators have reported failure in the escape slide preventing the forward passenger door opening. This [Brazilian] AD is being issued to prevent failure of this system which could impede an emergency evacuation and increase the chance of injury to passengers and flight crew.

* * * * *

The required action is repetitive re-packing of certain forward door escape slides. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/​#!documentDetail;​D=​FAA-2012-1108-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comments received.

Request to Reference Newer Revisions of Service Information

Embraer requested that paragraphs (h), (j)(1)(i), and (j)(1)(ii) of the NPRM (77 FR 65144, October 25, 2012) reference newer revisions of the maintenance review board reports. These new revisions are EMBRAER 170/175 Maintenance Review Board Report, MRB-1621, Revision 8, dated August 20, 2012; and EMBRAER 190/195 Maintenance Review Board Report, MRB-1928, Revision 6, dated August 20, 2012.

We agree to revise paragraph (h) of this final rule to also reference the newer revisions. However, paragraphs (j)(1)(i) and (j)(1)(ii), along with paragraphs (j)(1)(iii), (j)(1)(iv), and (j)(2) of the NPRM (77 FR 65144, October 25, 2012), were removed from this final rule and are identified in the Incorporation by Reference section (paragraph (k) of this final rule).

Request To Add Alternative Maintenance Instructions for Model ERJ 190-100 ECJ Airplanes

Embraer requested that the NPRM (77 FR 65144, October 25, 2012) reference Task 25-65-01-001, Emergency Evacuation Slide Assembly, in EMBRAER Lineage 1000 Maintenance Planning Guide, MPG-2928, Revision 3, dated September 28, 2012 (for Model ERJ 190-100 ECJ airplanes), instead of Section 1, “System and Powerplant Maintenance Requirements,” of EMBRAER 190 Maintenance Review Board Report, MRB-1928, Revision 5, dated November 11, 2010. Task 25-65-01-001 of the EMBRAER 190/195 Maintenance Review Board Report, MRB-1928, Revision 6, dated August 20, 2012; and Task 25-65-01-001 of Section 1, “System and Powerplant Maintenance Requirements,” of EMBRAER 190 Maintenance Review Board Report, MRB-1928, Revision 5, dated November 11, 2010; are not applicable to the ERJ 190-100 ECJ model.

We agree. Since operators of Model ERJ 190-100 ECJ airplanes are not able to comply with the requirements of this final rule using EMBRAER 190/195 Maintenance Review Board Reports, we have added paragraph (h)(2) to this final Start Printed Page 541rule to allow those operators to use the EMBRAER Lineage 1000 (ERJ 190-100 ECJ) Maintenance Planning Guide instead. This change does not expand the scope of the NPRM (77 FR 65144, October 25, 2012).

Request To Extend Repetitive Re-packing Interval

US Airways requested that the repetitive re-packing interval in its current slide maintenance program be left at 36 months instead changing it to the 18 months proposed in the NPRM (77 FR 65144, October 25, 2012). US Airways suggested a one-time re-pack interval of 18 months and a repetitive re-pack interval of 36 months; otherwise, the reduced interval would add extensive work-hours and cost to change to and maintain an 18-month repetitive re-pack interval.

We disagree with the requested change. To allow a 36-month repetitive re-pack interval instead of an 18-month re-pack interval would defeat/counteract the intent of this AD. Over time, the slide can develop a “set” position, which prevents the slide from properly deploying in an emergency. Re-packing at the reduced interval of 18 months is intended to prevent the “set” and improves reliability of the slide in an emergency. We have not changed this final rule in this regard.

Request To Allow Credit for Previously Re-packed Slides

US Airways requested a time allowance for slides that have been previously re-packed using the Goodrich service information. US Airways stated that regardless if its slides have been re-packed, the 18-month requirement is enforced. US Airways requested that those slides that have been previously re-packed using the applicable Goodrich service information be exempt from the 18-month re-packing requirement and be allowed to enter the repetitive maintenance schedule at the 36-month overhaul interval.

We disagree. As explained in the comment response to “Request to Extend Repetitive Re-packing Interval,” the intent of this AD is to prevent “set” by re-packing the slide at 18-month intervals instead of only at the 36-month maintenance overhaul. Paragraphs (g) and (h) of this AD specify that re-packing must be done at least every 18 months, but accomplishing an overhaul instead is also acceptable since the overhaul process includes re-packing the slide. An operator could choose to re-pack the slide at 18 months, overhaul the slide at 36 months, re-pack at 54 months, overhaul at 72 months, and so on. However, operators should note that once the slide is 15 years old, the task specified in paragraph (h) of this final rule currently requires that the slides be overhauled at intervals not to exceed 12 months. We have not changed this final rule in this regard.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes:

  • Are consistent with the intent that was proposed in the NPRM (77 FR 65144, October 25, 2012) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 65144, October 25, 2012).

Costs of Compliance

We estimate that this AD affects 235 products of U.S. registry. We also estimate that it will take about 2 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 between $435 and $542 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to U.S. operators to be between $153,065 and $180,136, or $605 and $712 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.
