Summary
We propose to adopt a new airworthiness directive (AD) for all Quest Aircraft Design, LLC Model KODIAK 100 airplanes. This proposed AD was prompted by reports of cracks found in certain nose landing gear forks. This proposed AD would require a one-time inspection to determine if the affected nose landing gear fork is installed, repetitive inspections of the affected nose landing gear fork for cracks, repetitive inspections of the shimmy damper bracket for looseness if the affected nose landing gear fork is installed, and rework/replacement of parts as necessary. We are proposing this AD to address the unsafe condition on these products.
