AD 2008-23-17

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

[E]scape slide system installation [was found with] * * * tie- down straps which are used for escape slide packing [having not been removed]. The non-removal of the tie-down straps does not allow the aircraft door to reach the fully open position and the consequent deployment of the escape slide system in a * * * emergency evacuation, affecting the occupying safety.

The unsafe condition is failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation. We are issuing this AD to require actions to correct the unsafe condition on these products.

Final rule.

2008-23-17 Empresa Brasileira de Aeronautica S.A. (EMBRAER): Amendment 39-15738. Docket No. FAA-2008-0889; Directorate Identifier 2008-NM-092-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective December 30, 2008.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD.
(1) EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU, -200 LR, -200 STD, and -200 SU airplanes, serial numbers 17000002, 17000004 thru 17000013, and 17000015 thru 17000196, certificated in any category.
(2) EMBRAER Model ERJ 190-100 STD, -100 LR, -100 IGW, -100 ECJ, -200 STD, -200 LR, and -200 IGW airplanes, serial numbers 19000002, 19000004 thru 19000132, and 19000135, certificated in any category.

Subject

(d) Air Transport Association (ATA) of America Code 25: Equipment/Furnishings.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

[E]scape slide system installation [was found with] * * * tie- down straps which are used for escape slide packing [having not been removed]. The non-removal of the tie-down straps does not allow the aircraft door to reach the fully open position and the consequent deployment of the escape slide system in a * * * emergency evacuation, affecting the occupying safety.

The unsafe condition is failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation. The corrective action involves inspection of the forward and rearward doors' emergency evacuation slide packs for the presence of tie-down straps, and, if applicable, removal of the tie-down straps.

Actions and Compliance

(f) Unless already done: Within 600 flight hours after the effective date of this AD, carry out a general visual inspection (GVI) of the emergency evacuation slide packs installed on the forward and rearward doors, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 170-25-0088, dated December 21, 2007; or 190-25-0062, dated December 21, 2007; as applicable. If tie-down straps are found, they must be cut and removed from the slide pack before further flight.

Note 1: For the purposes of this AD, a general visual inspection (GVI) is: "A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.''

FAA AD DifferencesNote 2: This AD differs from the MCAI and/or service information as follows: No differences.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 21, 2008 (73 FR 49362). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

[E]scape slide system installation [was found with] * * * tie- down straps which are used for escape slide packing [having not been removed]. The non-removal of the tie-down straps does not allow the aircraft door to reach the fully open position and the consequent deployment of the escape slide system in a * * * emergency evacuation, affecting the occupying safety.

The unsafe condition is failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation. The corrective action involves inspection of the forward and rearward doors' emergency evacuation slide packs for the presence of tie-down straps, and, if applicable, removal of the tie-down straps. You may obtain further information by examining the MCAI in the AD docket.

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 available data and determined that air safety and the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might alsohave required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD.

Costs of Compliance

We estimate that this AD will affect about 144 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 $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $23,040, or $160 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 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); and
3. 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
