Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2009-10-04, which applies to certain Diamond Aircraft Industries GmbH (type certificate now held by Diamond Aircraft Industries Inc.) Model DA 40 and DA 40 F airplanes. AD 2009-10-04 requires repetitively inspecting the nose landing gear (NLG) leg for cracks and replacing the NLG leg if cracks are found. Since the FAA issued AD 2009-10-04, Transport Canada updated mandatory continuing airworthiness information (MCAI) to correct this unsafe condition on these products. This proposed AD results from changes made to the part replacement options and the repetitive inspections. This proposed AD would require doing repetitive detailed inspections of the NLG leg pivot axle for cracking and if cracking is found replacing that part with a serviceable part. This proposed AD would also require eventually replacing all NLG legs having certain part numbers with serviceable parts, if not already done, and prohibit installing affected parts. Replacing affected parts with serviceable parts would be terminating action for the repetitive inspections specified in this proposed AD. The FAA is proposing this AD to address the unsafe condition on these products.
