AD NUMBER: 2009-01-05
MANUFACTURER: Empresa
SUBJECT: Airworthiness Directive 2009-01-05
SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Embraer has issued the Service Bulletin (SB) No. 145-00-0032 to provide instructions to modify the EMB-145 ( ) aircraft and allow operation with an increased Maximum Takeoff Weight (MTOW). Reassessment of the Damage Tolerance Analysis during development of the SB resulted in changes to the Airworthiness Limitation Items (ALI) for those modified aircraft to include new tasks and to revise some existing ones and its respective intervals. Failure to inspect some structural components, according to the new tasks and intervals for those modified aircraft, could prevent a timely detection of fatigue cracking. Undetected fatigue cracking in these components could adversely affect the structural integrity of these airplanes. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
