**SUMMARY :**  We propose to supersede airworthiness directive (AD) 89–12–10, which applies to certain The Boeing Company Model 747 series airplanes.


### 58963 Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules

AD 89–12–10 currently requires replacement of certain underwing fueltank access doors with stronger, fireresistant doors. Since we issued AD 89– 12–10, we have received reports indicating that a standard access door was located where an impact-resistant access door was required, and stencilswere missing from some impactresistant access doors. Stencils are required to indicate that the door is impact-resistant and to indicate the correct location for installation of the impact-resistant door. This proposed AD would require an inspection of the left- and right-hand wing fuel tank access doors to determine whether impact-resistant access doors are installed in the correct locations, and replacement of any door with an impact-resistant access door if necessary. This proposed AD would also require an inspection for the presence of stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. This proposed AD would also require revising the maintenance program to incorporate changes to the airworthiness limitations section. This proposed AD would also add airplanes to the applicability. We are proposing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire.

**DATES :**  We must receive comments on this proposed AD by November 12,
2013.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

On May 22, 1989, we issued AD 89– 12–10, Amendment 39–6230 (54 FR 23643, June 2, 1989) (‘‘AD 89–12–10’’), for certain The Boeing Company Model 747–100, 747–200, 747–300, and 747– SP series airplanes. AD 89–12–10 requires replacement of certain underwing fuel tank access doors with stronger, fire-resistant doors. AD 89–12– 10 resulted from several incidents of door penetration by tire and engine debris, which resulted in spillage of significant quantities of fuel. We issued AD 89–12–10 to prevent a fire in the wing fuel tank.

Actions Since AD 89–12–10 Was Issued

Since we issued AD 89–12–10, additional access doors, that may be installed on additional airplanes that were not identified in AD 89–12–10, have been identified that may be subject to the unsafe condition. Certain doors are addressed in other service bulletins. Additionally, due to repainting of the lower wing skin, stencils that identify the access door may no longer be in place to provide a visual confirmation that the correct door is installed.

Relevant Service Information

We reviewed the following service information. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2013–0790.

• Boeing Service Bulletin 747–28– 2315, dated January 11, 2012.

• CDCCL Task 57–AWL–01, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Sub-section B, Airworthiness Limitations (AWLs)—Fuel Systems, of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs) of Boeing 747– 400 Maintenance Planning Data (MPD) Document D621U400, Revision August
2012.

• CDCCL Task 57–AWL–01, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Sub-section C, Airworthiness Limitations—Fuel Systems, of the Boeing 747–100/200/300/SP Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs) Document D6–13747–CMR, Revision August 2012.

FAA’s Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition identified previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements

This proposed AD would retain none of the requirements of AD 89–12–10. Since that AD was issued, the FAA issued section 121.316 of the Federal Aviation Regulations (14 CFR 121.316) requiring that each turbine-powered transport category airplane meet the requirements of section 25.963(e) of the Federal Aviation Regulations (14 CFR 25.963(e)). Section 25.963(e) outlines the certification requirements for fuel tank access covers on turbine powered transport category airplanes.


### 58964 Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules

This proposed AD would require accomplishing the actions specified in the service information described previously. This proposed AD would add Models 747–400, 747–400D, 747– 400F, and 747SR series airplanes to the applicability, and clarify the applicability of AD 89–12–10, Amendment 39–6230 (54 FR 23643, June 2, 1989) to identify models listed in the current type certification data sheets (TCDS).

This proposed AD would also require inspecting fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations and replacing any door with an impact-resistant access door if necessary; inspecting application ofstencils and index markers of impactresistant access doors and application of new stencils or index markers if necessary; and revising the maintenance
program.

This proposed AD requires revisions to certain operator maintenance documents to include a new CDCCL. Compliance with CDCCLs is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator might not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to the procedures specified in paragraph (j) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure.

After accomplishment of the revision required by paragraph (h) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j) of this AD. Costs of Compliance

We estimate that this proposed AD affects 189 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection .................................................. Up to 13 work-hours × $85 per hour = $1,105. $0 Up to $1,105 ........... Up to $208,845.

Maintenance program revision .................. 1 work-hour × $85 per hour = $85. 0 85 ............................ 16,065.

We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these replacements:



### O N



### -CONDITION 

### COSTS

Action Labor cost Parts cost Cost per product

Replacement per door ........................................................................ 3 work-hours × $85 per hour = $255 ..... $8,000 $8,255 Stencil and index marker (14 doors) .................................................. 17 work-hours × $85 per hour = $1,445 0 1,445

According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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), (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.
List of Subjects in 14 CFR Part 39

**Airworthiness Directives; Bombardier, Inc. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD–100–1A10 (Challenger 300) airplanes. This proposed AD was prompted by multiple reports of erratic electrical status indications on the push button annunciators and the engine instrument and crew alerting system. Certain of those reported incidents resulted in the airplane experiencing a momentary loss of electrical power and loss of flight displays. This proposed AD would require modification of the direct current power centers. We are proposing this AD to prevent loss of electrical power, which could result in the loss of flight displays and reduced controllability of the airplane.

**DATES :**  We must receive comments on this proposed AD by November 12,
2013.
