Mid-Air Collision Hazard
IF YOU SEE WILDFIRE SMOKE, FLY AWAY! The Federal Aviation Administration (FAA) issues Temporary Flight Restrictions (TFRs) to prohibit aircraft, including Unmanned Aircraft Systems (UAS) or drones, from entering designated areas during wildfires. These restrictions are essential for protecting lives and property while ensuring that firefighting aircraft can operate safely and effectively. During a wildfire, expect multiple helicopters and airplanes flying in coordinated patterns at various altitudes. These aircraft will be maneuvering around the fire perimeter and within the smoke column as they conduct firefighting operations. Do not report wildfires that already have firefighting aircraft on the scene. If you

WANNA FLY WITH THE EAGLES MAKE SURE YOU’RE LEGAL
Aircraft operators must verify that an aircraft is validly registered before the aircraft can be operated. Per 14 CFR part 47, section 47.3, no person may operate an aircraft unless it has been registered by its owner. Pilots should review the registration certificate on the aircraft to ensure that it is valid. Evidence of valid registration is an unexpired Certificate of Registration kept onboard. For aircraft that have recently changed ownership, but the new Certificate of Registration has not been issued yet, temporary authority to operate is allowed under 14 CFR part 47, section 47.31(c) with a copy of the
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
