AD 96-14-03 61 FR 34368

This amendment supersedes an existing airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-301,--311, and-- 315 series airplanes, that currently requires modification of the airspeed limitations placard and revision of the Airplane Flight Manual to specify operating at lower airspeeds when the airplane is operating at full flaps. That action also provides for the optional termination of the requirements of the AD for certain airplanes. That action was prompted by a report that incorrect rivets were installed on the outboard flaps assemblies of these airplanes. The actions specified by that AD are intended to prevent structural failure of the outboard flaps of the wings due to the installation of incorrect rivets in the flap assemblies, which could result in reduced controllability of the airplane. This new amendment requires the installation of the previously optional terminating modification on certain airplanes. DATES: Effective August 6, 1996.
