Definition of Substantial Damage
Substantial damage refers to any type of damage or failure that negatively impacts the structural strength, performance, or flight characteristics of an aircraft to the point where major repairs or replacement are required to restore the affected component to its original condition. This type of damage poses a significant risk to the safety of the aircraft, passengers, and crew members.
Examples of substantial damage may include damage or failure of the aircraft’s primary structural elements, such as wings, fuselage, or cockpit. Additionally, damage to complex systems such as engines, propellers, or avionics, may also be considered substantial if it compromises the functionality of the aircraft.
On the other hand, damage such as bent fairings, cowling, or small punctured holes, as well as ground damage to rotor or propeller blades and damage to landing gears, flaps, or wing tips, may not necessarily be considered “substantial damage.” This is because this type of damage typically does not pose a threat to the safety of the aircraft or its occupants.
It’s important to promptly identify and report any instance of substantial damage to the relevant authorities to ensure the aircraft remains safe to operate and to avoid potential aviation accidents.
