Maintenance Safety Tip – The “B” Nut can be Deadly
The “B” Nut can be Deadly All aircraft maintainers have heard or used the term “B” nut. It is the common description of the nut that is used to connect fluid lines and hoses. It is a very simple component; but does a critical job. It provides a reliable seal in plumbing systems and usually results in ease of maintenance for AMTs. It is designed to provide years of reliable service. However, “B” nut reliability is only as good as how you treat it. We disconnect and connect them many times during our careers - right?

NTSB Safety Alert – Aluminum Propeller Blades: Prevent Fractures with Proper Inspections and Maintenance
Aluminum propeller blades can be susceptible to fatigue, cracking, and fracture if a small nick, pit, or corrosion on the surface or edge is not found and repaired during preflight inspection or maintenance. Such damage can concentrate stress from normal airplane operation loads, resulting in fatigue crack initiation and growth followed by propeller blade fracture. Aluminum is more commonly used for airplane propeller blades than composite propeller blades or wood. Fatigue cracking and fracture of a propeller blade can damage the airframe, and engine, and cause a possible loss of control. Airplanes utilized for aerial application and coastal operations, as well

Photo and Video Chronology — Kīlauea East Rift Zone webcam maintenance and new Kīlauea interferogram
October 23, 2024 — Routine maintenance on Kīlauea East Rift Zone webcam October 23, 2024—InSAR image of Kīlauea middle East Rift Zone deformation This map shows recent deformation at Kīlauea over the timeframe of October 6–18, 2024. Data were acquired by the European Space Agency's Sentinel-1 satellites. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion. The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar). The round feature north of Nāpau and Makaopuhi Craters on the middle East Rift Zone
