Diamond DA42 VI — Airworthiness Directives

This document is a proposed Airworthiness Directive (AD) issued by the FAA for Diamond Aircraft Industries GmbH airplanes, specifically targeting the DA 42, DA 42 NG, and DA 42 M-NG models. The directive is prompted by safety concerns regarding the nose landing gear (NLG) actuator attachment lever, which has been reported to fail and detach from the NLG leg, potentially leading to reduced control of the aircraft. The AD mandates repetitive inspections of the NLG actuator attachment lever for cracks and damage, along with corrective actions if necessary. The FAA aims to ensure the safety and airworthiness of these aircraft by addressing this identified unsafe condition through this proposed rulemaking.

• The AD applies to Diamond DA 42, DA 42 NG, and DA 42 M-NG models.
• Inspect the NLG actuator attachment lever for cracks and damage at specified intervals.
• For assemblies with less than 1,800 hours TIS, inspect within 200 hours after reaching 1,800 hours TIS or within 12 months.
• For assemblies with 1,800 or more hours TIS, inspect within 210 hours after the AD's effective date or within 12 months.
• Estimated cost for inspection is $85 per airplane, totaling approximately $3,400 for all affected aircraft.
