Start Preamble

AGENCY:

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

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain Goodrich evacuation systems approved under TSO-C69, TSO-C69a, TSO-C69b, and TSO-69c, installed on certain Boeing, McDonnell Douglas, and Airbus transport category airplanes. For certain systems, this proposed AD would require replacing the evacuation systems shear-pin restraints with new ones. For certain other systems, this proposed AD would require an inspection for manufacturing lot numbers; and a general visual inspection of the shear-pin restraint for discrepancies, and corrective actions if necessary. This proposed AD is prompted by several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are proposing this AD to prevent failure of the evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation.

DATES:

We must receive comments on this proposed AD by July 23, 2007.

Comments will be available in the AD docket shortly after the DMS receives them.

Discussion

We have received several reports indicating that Goodrich evacuation systems installed on certain Boeing Model 747 airplanes and Model 767 airplanes have not deployed properly due to corroded shear-pin restraints. The corrosion problem arose concurrently with a 1998 change in the anodize specification for restraint bodies. Corrosion of the shear-pin restraints, if not corrected, can lead to higher than designed release values, and in severe cases, can cause the two halves of the restraints to freeze up, which can lead to improper deployment and/or loss of use of the evacuation system. That loss could impede emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation.

Other Relevant Rulemaking

The reports involved certain Boeing Model 747 airplanes and Model 767 airplanes that are equipped with the affected Goodrich evacuation system as part of a type certificate (TC); however, certain Goodrich evacuation systems installed as a technical standard order (TSO) appliance on certain Airbus, Boeing and McDonnell Douglas transport category airplanes use the same restraints as those used by the affected type certificated Goodrich units. Therefore evacuation systems approved by either TSO or TC are subject to the identified unsafe condition. We are planning to issue similar rulemaking (Directorate Identifier 2005-NM-139-AD) for certain Boeing Model 747 airplanes and Model 767 airplanes that are equipped with certain type certificated Goodrich evacuation systems.

Relevant Service Information

We have reviewed Goodrich Service Bulletins 25-343, Revision 3, dated January 12, 2007; and 25-344, Revision 2, dated October 11, 2006. Goodrich Service Bulletin 25-343 affects evacuation systems installed on certain Boeing and McDonnell Douglas transport category airplanes. Goodrich Service Bulletin 25-344 affects evacuation systems installed on certain Airbus transport category airplanes. For certain systems, the service bulletins describe procedures for replacing the shear-pin restraints with new, improved restraints. For certain other systems, the service bulletins describe procedures for an inspection to verify the manufacturing lot number of the restraints; and a general visual inspection of the restraints for discrepancies (i.e., corrosion, security of pin retainer/label, overall condition, and lack of play), and corrective action if necessary. The corrective action is replacing the shear-pin restraints with new shear-pin restraints. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. Therefore, we are proposing this AD, which would require you to use the service information described previously to perform these actions, except as discussed under “Difference Between this Proposed AD and the Service Bulletins.”

Difference Between This Proposed AD and the Service Bulletins

Although the service bulletins recommend accomplishing the replacement or inspection “at the next shop visit,” we have determined that this imprecise compliance time would not address the identified unsafe condition soon enough to ensure an adequate level of safety for the affected fleet. In developing an appropriate compliance time for this AD, we considered the manufacturer's recommendation, the degree of urgency associated with the subject unsafe condition, and the average utilization of the affected fleet. In light of all of these factors, we find that a compliance time of 18 months for Goodrich evacuation systems installed on Boeing Model 767 off-wing ramp/slide units and 36 months for all other evacuation systems represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. We have coordinated this difference with the manufacturer.

Costs of Compliance

This proposed AD would affect certain Goodrich evacuation systems installed on about 2,844 airplanes worldwide. This proposed AD would affect about 1,240 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this proposed AD. Start Printed Page 31763

InspectionBetween 2 and 9$80NoneBetween $160 and $720Between 2 and 12.Between $396,800 and $10,713,600.

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 have 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 that the 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

Unsafe Condition

(d) This AD is prompted by several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are issuing this AD to prevent failure of the evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation.

Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Service Bulletin Reference

(f) The term “service bulletin,” as used in this AD, means the following service bulletins, as applicable:

(1) For Goodrich evacuation systems identified in Table 3 of this AD: Goodrich Service Bulletin 25-344, Revision 2, dated October 11, 2006; and

(2) For Goodrich evacuation systems identified in Tables 1 and 2 of this AD: Goodrich Service Bulletin 25-343, Revision 3, dated January 12, 2007.

Compliance Times

(g) Perform the actions specified in paragraph (h) of this AD at the applicable compliance time specified in paragraph (g)(1) or (g)(2) of this AD.

(1) For Goodrich evacuation systems installed on Boeing Model 767 airplanes as off-wing ramp/slide units and identified in Table 1 of this AD: Do the actions within 18 months after the effective date of this AD.

(2) For Goodrich evacuation systems other than those identified in paragraph (g)(1) of this AD: Do the actions within 36 months after the effective date of this AD.

Replacement, or Inspections and Corrective Action

(h) Do the actions specified in paragraph (h)(1) or (h)(2) of this AD in accordance with the Accomplishment Instructions of the applicable service bulletin.

(1) For Goodrich evacuation systems identified in paragraphs (c)(1)(i) through (c)(1)(xxxi) inclusive in Table 1 of this AD, (c)(2)(i) through (c)(2)(iii) inclusive in Table 2 of this AD, and (c)(3)(i) through (c)(3)(xviii) inclusive in Table 3 of this AD: Replace the shear-pin restraints with new restraints.

(2) For Goodrich evacuation systems identified in paragraphs (c)(1)(xxxii) through (c)(1)(lxii) inclusive in Table 1 of this AD, (c)(2)(iv) through (c)(2)(ix) inclusive in Table 2 of this AD, and (c)(3)(xix) through (c)(3)(xxx) inclusive in Table 3 of this AD: Do an inspection to verify the manufacturing lot number of the shear-pin restraint. A review of airplane maintenance records is acceptable in lieu of this inspection if the manufacturing lot number of the shear-pin restraint can be conclusively determined from that review.

(i) If a manufacturing lot number from 3375 through 5551 inclusive is found, before further flight, replace the shear-pin restraint with a new restraint.

(ii) If a manufacturing lot number from 3375 through 5551 inclusive is not found, do a general visual inspection of the shear-pin restraints for discrepancies (i.e., corrosion, security of pin retainer/label, overall condition, and lack of play). If any discrepancy is found, before further flight, replace the shear-pin restraint with a new restraint.

Note 1: For the purposes of this AD, a general visual inspection 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 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.”

Parts Installation

(i) As of the effective date of this AD, no Goodrich evacuation system identified in paragraph (h)(1) of this AD may be installed on any airplane, unless the shear-pin restraints have been replaced with new restraints in accordance with paragraph (h)(1) of this AD.

(j) As of the effective date of this AD, no Goodrich evacuation system identified in paragraph (h)(2) of this AD may be installed on any airplane, unless the shear-pin restraints have been inspected and found acceptable in accordance with paragraph (h)(2) of this AD.

Credit for Actions Done Using Previous Service Information

(k) Replacements and inspections done before the effective date of this AD in accordance with the applicable service bulletins identified in Table 4 of this AD, are acceptable for compliance with the requirements of paragraph (h) of this AD.
