Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

It has been found that some adhesive tapes used in the interior furnishings do not comply with the applicable flammability requirements. In case of some nearby ignition source, fire may propagate to the aircraft.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

DATES:

We must receive comments on this proposed AD by December 3, 2007.

ADDRESSES:

You may send comments by any of the following methods:

  • Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

The Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2007-03-04, effective April 10, 2007 (referred to after this as “the MCAI”), to correct an unsafe Start Printed Page 61823condition for the specified products. The MCAI states:

It has been found that some adhesive tapes used in the interior furnishings do not comply with the applicable flammability requirements. In case of some nearby ignition source, fire may propagate to the aircraft.

The corrective actions include an inspection to determine the presence of cotton adhesive tape, and replacement of the tape with new tape if necessary. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

EMBRAER has issued Service Bulletin 145LEG-25-0080, dated October 10, 2006. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

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 also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 41 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $6,560, 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation:

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 proposed AD and placed it in the AD docket.

The corrective actions include an inspection to determine the presence of cotton adhesive tape, and replacement of the tape with new tape if necessary.

Actions and Compliance

(f) Within 48 months or 5,000 flight hours after the effective date of this AD, whichever occurs first, unless already done: Carry out a general visual inspection (GVI) for presence of cotton adhesive tape, part number (P/N) FMM 1121-5, in the interior of center-passenger cabin furnishings, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-25-0080, dated October 10, 2006. If any cotton tape, P/N FMM 1121-5, is found, before further flight, replace it with new PVF adhesive tape bearing P/N KB42/75, as specified in paragraphs (f)(1) and (f)(2) of this AD.

(2) Replace cotton adhesive tapes, P/N FMM 1121-5, applied to electrical cables in the bottom of the forward galley assembly, to electrical cables and inside the left-hand (LH) and right-hand (RH) forward and LH aft side ledges, and to electrical cables, flexible hose of the video monitor, soundproofing blanket, Start Printed Page 61824and in the LH and RH forward and RH aft pocket door covers and partitions, with new PVF adhesive tapes bearing P/N KB42/75 with heat-shrinkable sleeve, P/N RNF-100-1-0, in accordance with the Accomplishment Instructions of the service bulletin.

Note 1:

For the purpose of this AD, a general visual inspection (GVI) is: “A visual examination of the interior or exterior area of an 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 enhance 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 drop-light, 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 Differences

Note 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.
