Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Model 1900D airplanes. This proposed AD would require you to accomplish a one-time inspection for missing rivets on certain areas of the airplane and, if necessary, install rivets. This proposed AD is the result of Raytheon identifying several instances of missing rivets on these airplanes. The actions specified by this proposed AD are intended to detect and correct an understrength condition in the fuselage, which could result in the failure of the fuselage. Such failure could lead to loss of control of the airplane in flight.
