**Airworthiness Directives; The Boeing Company Airplanes** 

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

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

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. This proposed AD was prompted by a determination that a repetitive test is needed to inspect the components on airplanes equipped with a certain air distribution system configuration. This proposed AD would require doing repetitive testing for correct operation of the equipment cooling system and low pressure environmental control system, and corrective actions if necessary. We are proposing this AD to detect and correct latent failures of the equipment cooling system and low pressure environmental control system, which could result in smoke in the flight deck and possible loss of aircraft control.

Discussion

We received a report indicating that a repetitive test is needed for inspection of the components on airplanes equipped with an air distribution system that was reconfigured using Boeing Special Attention Service Bulletin 737–26–1122, Revision 1, dated August 13, 2009. Boeing Special Attention Service Bulletin 737–26– 1122, Revision 1, dated August 13, 2009, provided procedures for installing relays and diodes to the J24 junction box assembly and making wiring changes to the environmental control system. Without the repetitive test, failures of components could possibly be latent for extended periods. A cargo fire event, in conjunction with a latent failure of the air distribution system, can possibly result in smoke penetration into occupied areas. This condition, if not corrected, could result in smoke in the flight deck and possible loss of aircraft control.

Related Service Information Under 1 CFR Part 51

We reviewed Boeing Alert Service Bulletin 737–26A1137, dated May 22, 2014. The service information describes procedures for repetitive testing for correct operation of the reconfigured equipment cooling system and low pressure environmental control system. Refer to this service information for information on the procedures and compliance times.

Boeing Alert Service Bulletin 737– 26A1137, dated May 22, 2014, specifies, for certain airplanes, prior or concurrent accomplishment of Boeing Special Attention 737–26–1122, Revision 1, dated August 13, 2009. Boeing Special Attention 737–26–1122, Revision 1, dated August 13, 2009, describes procedures for installing relays and diodes to the J24 junction box assembly and making wiring changes to the environmental control system.

This service information is reasonably available; see **ADDRESSES** for ways to access this service information.

FAA’s Determination

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

This proposed AD would require accomplishing the actions specified in the service information described previously.

The phrase ‘‘corrective actions’’ is used in this proposed AD. ‘‘Corrective actions’’ are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs.
Explanation of Required for Compliance (RC) Steps in Service Information

The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/operator’s understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The steps identified as RC (required for compliance) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition.

Steps that are identified as RC in any service information must be done to comply with the proposed AD. However, steps that are not identified as RC are recommended. Those steps that are not identified as RC may be deviated from using accepted methods in accordance with the operator’s maintenance or inspection program without obtaining approval of an alternative method of compliance (AMOC), provided the steps identified as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps identified as RC will require approval of an AMOC.


### 17370 Federal Register / Vol. 80, No. 62 / Wednesday, April 1, 2015 / Proposed Rules

Costs of Compliance

We estimate that this proposed AD affects 1,372 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

Operational Test ...................... 4 work-hours × $85 per hour = $340 per operation test cycle. $0 $340 per operation test cycle $466,480 per operation test cycle.

We estimate the following costs to do any necessary isolation and 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

Perform system fault isolation and replace faulty component. 10 work-hours × $85 per hour = $850 ............................. $0 $850

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),

(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

Section 119 of title 23, U.S.C., requires the Secretary to establish a process that States DOTs would use to develop a State asset management plan. On February 20, 2015, FHWA published in the Federal Register an NPRM proposing to establish a process for the development of a State asset management plan to improve or preserve the condition of the assets and the performance of the National Highway System as they relate to physical assets. State asset management plans must include strategies leading to a program of projects that would: (1) Make progress toward achievement of the State targets for asset condition and performance of the NHS in accordance with 23 U.S.C. 150(d), and (2) support progress toward the achievement of the national goals identified in 23 U.S.C. 150(b). 23 U.S.C. 119(e)(2). The development and implementation of an asset management plan is an important
