Airworthiness Directives; Bell Helicopter Textron
We propose to supersede airworthiness directive (AD) 75-26-05 for Bell Helicopter Textron (Bell) Model 204B, 205A-1 and 212 helicopters. AD 75-26-05 currently requires removing and visually inspecting each main rotor (M/R) blade and, depending on the inspection's outcome, repairing or replacing the M/R blades. This proposed AD would require more frequent inspections of certain M/R blades and would also apply to Model 205A helicopters. This proposed AD would have no requirement that helicopter blades be removed to conduct the initial visual inspections. These proposed actions are intended to detect a crack and prevent failure of an M/R blade and subsequent loss of helicopter control.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117A-3, MBB-BK 117A-4, MBB-BK 117B-1, MBB-BK 117B-2, and MBB-BK 117C-1 helicopters. This proposed AD would require removing adhesive seals from the exterior and interior door jettisoning system on the left and right sliding doors. This proposed AD is prompted by reports that the adhesive seal prevented the doors from jettisoning properly. The proposed actions are intended to remove the adhesive seal to allow the doors to jettison properly so occupants can exit the helicopter during an emergency.
