Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. The NPRM published in the Federal Register on August 23, 2013 (78 FR 52465). The NPRM was prompted by three reports of cracking in the rear pressure bulkhead (RPBH) web. The NPRM proposed to require inspecting the RPBH web for cracking, and repairing if necessary. We are issuing this AD to detect and correct cracking ofthe RPBH web, which could result in inflight decompression of the airplane and possible injury to the occupants.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0219, dated October 19, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI
states:

Three reports have been received of a crack in the rear pressure bulkhead (RPBH) web, just below the horizontal beam XI between buttock lines BL425L and BL425R, in the centre web bay below the pressure relief valves.

This condition, if not detected and corrected, could result in an exponential crack growth rate, possibly leading to failureof the affected RPBH web, resulting in inflight decompression of the aeroplane and possible injury to occupants.

A repetitive inspection requirement has been published in issue 10 of Fokker Services [Airworthiness Limitations Section] ALS Report SE–623 under task number 534106– 00–05. The threshold to start this ALS-task is 30,000 [total] flight cycles (FC). However, it is known that many aeroplanes have already exceeded this threshold.


## 10336 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations

For the reasons described above, this [EASA] AD requires a one-time inspection [detailed visual or high frequency eddy current inspection] of the affected RPBH web for cracks and, depending on findings, accomplishment of a repair. The repair can also be applied at any time as a modification, thereby exempting the aeroplane from (further) repetitive ALS task 534106–00–05 inspections. 

### You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2013-0699-
0002

. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 52465, August 23, 2013) 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 this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 52465, August 23, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 52465, August 23, 2013). Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

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

Inspection ........................................................ 5 work-hours X $85 per hour = $425 ............ $0 $425 $1,700



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



### O N 

### -C ONDITION 

### C OSTS

Action Labor cost Parts cost Cost per product

On-condition inspection and repair .............................. 16 work-hours × $85 per hour = $1,360 ...................... $0 $1,360



### 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 that 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);

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. Examining the AD Docket

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!docketDetail;D=FAA-2013-0699; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

### Airworthiness Directives; the Boeing **Company Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737–600, –700, –800, –900, and –900ER series airplanes modified by particular supplemental type certificates (STCs). This AD was prompted by reports of cracks found during inspections of the in-flight entertainment system radome assembly. This AD requires repetitive detailed inspections for cracks in the radome assembly, and replacement of the radome if necessary. We are issuing this AD to detect and correct cracks in the in-flight entertainment system radome assembly, which could result in the radome (or pieces) separating from the airplane and striking the tail, and consequently reducing the controllability of the airplane.
