Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain British Aerospace Jetstream Model 3101 airplanes. This AD requires installing additional stringers at the lower fuselage skin panels between the main and rear spar frames. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified in this AD are intended to correct a strength deficiency in the area of the lower fuselage skin panels between the main rear spar frames, which, if not corrected, could result in reduced or loss of control of the airplane during maximum speed limit operations.
