Oh dear…

FAA proposed airworthiness directive (AD) July 2019

Final Rule Dec 2019

This AD was prompted by reports that the nose landing gear (NLG) retracted on the ground, with weight on the airplane's wheels, due to the incorrect installation of a NLG downlock pin in the apex pin inner bore of the NLG lock link assembly. The FAA is issuing this AD to address the NLG downlock pin being incorrectly installed in the apex pin inner bore of the NLG lock link assembly, which could result in the NLG retracting on the ground, possibly causing serious injuries to personnel and passengers and substantial damage to the airplane.
