If you thought your Bonanza or Baron missed a January, 2001, AD for the installation of missing rivets on the airframe, think again. The company has since discovered that not all affected aircraft serial numbers were included. A corrected AD has been issued by the FAA.
If you've had a new hub installed in your two-bladed Hartzell prop recently, this AD might be for you. The company has found defects in some hubs and replacements must be carried out within 50 or 100 hours depending on the type of aircraft installation.
