A method includes receiving fault code data identifying one or more fault conditions detected onboard an aircraft and receiving fault context data indicating one or more conditions of the aircraft in a timeframe associated with the condition(s). The method also includes generating (based on the fault code data, the fault context data, state data indicating a current state of the aircraft, and historical maintenance data) a first checklist display including a first set of incomplete checklist items. The method further includes receiving input indicating completion of one or more checklist items of the first set of incomplete checklist items and updating the state data based on the input. The method also includes generating (based on the fault code data, the fault context data, the updated state data, and historical maintenance data) a second checklist display including a second set of incomplete checklist items.

A replacement tip section for a rotor blade, from which a legacy tip section was removed, includes a blade tip portion configured to be attached to an intermediate section of the rotor blade after removal of the legacy section. The intermediate section has a connection feature at an end of the intermediate section to which the blade tip portion is attachable. The replacement tip section includes a transition region configured to be attached to a forward end of the connection feature. The transition region is configured to form a leading edge of the rotor blade and extends from the blade tip portion to form an opening into which the intermediate section is attached. The transition region includes a first end having a first airfoil that conforms to the intermediate section airfoil at the connection feature, and a second end having a second airfoil that conforms to the blade tip portion.

A profile for a trailing edge of an airfoil, the trailing edge including flanges, and the profile is U or V shaped, is made of composite material and includes: sections joined at a first profile end and defining an inner space, and recesses arranged along the two sections towards the inner space and complementary to each other between the two sections; wherein the profile is configured to follow a theoretical aerodynamic contour of the airfoil so that the two sections partially cover the trailing edge and the flanges are housed inside the inner space, and wherein each of the plurality of recesses defines at least two joining points through which the two flange of the trailing edge and the two sections are configured to be joined each other.

A data updating system for computing devices included in an aircraft, wherein one computing device in a first group of computing devices is, and one other computing device in a second group of computing devices is not, when the data of the computing device is updated, liable to affect the safety of the operator carrying out the maintenance on the aircraft. The system includes a data loading device, a connection connecting the data loading device with the computing device in the second group, and a data router connected to the data loading device, the data router transferring updating data to the computing devices in the first group only when a command by an operator in the cockpit of the aircraft is detected.

Certain aspects of the present disclosure provide techniques for a mobile adjustable stairway which has a first frame section which is adapted to be mobile and has fixed steps and a second frame section coupled to the first frame section such that relative movement there between can take place whereby the stairway is adjustable between a compacted form and an extended form. A set of floating steps is provided whereby each floating step is adapted to be progressively raised and lowered as the stairway as the second frame section is moved relative to the first frame section between the compacted and extended forms. The stairway also has a set of first components associated with each floating step operable to laterally stabilize the floating step when in the extended form; and a set of second components associated with each floating step operable to longitudinally stabilize the floating step when in the extended form.
