RIN 2120-AA64


Airworthiness Directives; Liberty Aerospace Incorporated Model XL-2 Airplanes


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


ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are correcting the address, telephone, and fax information for the reporting


requirement in Airworthiness Directive (AD) 2009-08-05, which applies to certain Liberty Aerospace


Incorporated Model XL-2 airplanes. AD 2009-08-05 currently requires repetitively inspecting the


exhaust muffler for cracks, replacing the exhaust muffler when cracks are found, and reporting the


results of the inspections to the FAA. Since AD 2009-08-05 became effective, the FAA's Atlanta


Aircraft Certification Office (ACO) moved, which has caused the office personnel problems in


receiving fax and mailed copies of the inspection result reports. This document corrects the mailing


address, telephone number, and fax information of the Atlanta ACO.


DATES:
 
This final rule is effective April 19, 2010. The compliance date of this AD is April 20,


2009, which is the same as the effective date of AD 2009-08-05.


As of April 20, 2009 (74 FR 16117, April 9, 2009), the Director of the Federal Register approved


the incorporation by reference of Liberty Aerospace, Inc. Service Document Critical Service Bulletin


(CSB) CSB-09-001, Revision Level B, Revised on March 18, 2009.

SUPPLEMENTARY INFORMATION:


Discussion


On April 3, 2009, we issued AD 2009-08-05, Amendment 39-15878 (74 FR 16117, April 9,


2009), to require repetitively inspecting the exhaust muffler for cracks, replacing the exhaust muffler


when cracks are found, and reporting the results of the inspections to the FAA.


Since AD 2009-08-05 became effective, the FAA's Atlanta Aircraft Certification Office (ACO)


moved, which has caused the office personnel problems in receiving fax and mailed copies of the


inspection result reports.


Consequently, the FAA sees a need to correct the mailing address, telephone number, and fax


information of the Atlanta ACO in AD 2009-08-05 to assure that the inspection results are received


and reviewed to help assure the continued operational safety of the affected airplanes. Thus, the FAA


is revising the AD to incorporate the language discussed above and to add the amendment to section


39.13 of the Federal Aviation Regulations (14 CFR 39.13).


Since this action only corrects the address, telephone number, and fax information for the


reporting requirement and does not require any additional actions over that originally required by AD


2009-08-05, it has no adverse economic impact and imposes no additional burden on any person than


was already required. Therefore, the FAA has determined that prior notice and opportunity for public


comment are unnecessary.
