Aircraft Effect
AD 2007-10-15 Cessna Caravan C208/C208B Requirement is the installation of a functional low airspeed awareness system to operate the airplane in known icing conditions. AD is to assure that the pilot has enough information and the necessary equipment to prevent loss of control of the airplane while in-flight during icing conditions. Supersedes AD 2006-06-06 Final rule eff 21 Jun
2007-CE-035-AD BAe Jetstream (all series) In-service reports have been received by BAE of failed bolts fitted to frame 199 wing spigot post assembly. If left uncorrected, failure of these bolts will severely compromise the structural integrity of the wing to fuselage attachment? failure of which would lead to loss of the aircraft.
