2004-21-01: The FAA is superseding an existing AD for certain Hartzell Propeller Inc. (formerly Hartzell Propeller Products Division) Model HC-B5MP-3( )/M10282A( )+6 five bladed propellers. That AD currently requires initial and repetitive torque check inspections on the attach bolts on certain model Hartzell HC-B5MP-3 five bladed propellers, and replacement of attach bolts if necessary. This AD requires the same inspections, but reduces compliance time for the initial inspection on certain Short Brothers Ltd. Model SD3-30 airplanes to before further flight and within 100 hours time-in-service for propellers installed on certain Aerospatiale (Nord) Model 262A airplanes. This AD also requires repetitive torque check inspections at reduced intervals on SD3-30 airplanes, and requires additional visual inspections of mounting flanges, and threads in hub bolt holes, and replacement of attach bolts and hubs, if necessary. This AD results from four reports in the last 12 months of eleven crackedor failed propeller attach bolts on Short Brothers Model SD3-30 airplanes. We are issuing this AD to prevent propeller separation from the airplane.
2013-17-06: We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by reports of loose nuts on contactors in the electrical power center (EPC), and in some cases, burned contactors. This AD requires inspecting and, if necessary, adjusting, the torque values of nuts on circuit breakers, contactors, and terminal blocks of the EPC and battery relay panel. This AD also requires inspecting to determine if certain parts are installed, and installing the parts if necessary. We are issuing this AD to detect and correct loose nuts, which could result in arcing and potentially an onboard fire, possibly resulting in damage to the airplane and injury to occupants or maintenance personnel.
