Requires replacing the nose landing gear (NLG) drag link bolt with one that has been manufactured with the proper heat treatment.
Full official abstract
This amendment adopts a new airworthiness directive (AD) that applies to Twin Commander Aircraft Corporation (Twin Commander) 500, 680, and 690 series airplanes that do not have a nose landing gear drag link bolt with the manufacturer's serial number, manufacture date, and the last three digits of the drawing number, 055, on the bolt head. This action requires replacing the nose landing gear (NLG) drag link bolt with one that has been manufactured with the proper heat treatment. This action was prompted by the failure of an improperly heat treated NLG drag link bolt causing collapse of the nose landing gear on a certain Twin Commander Model 690B airplane while taxiing. The actions specified by this AD are intended to prevent the NLG from collapsing, which if not corrected, could result in loss of the airplane.
