What is "tailstrike"

n. (context aviation English) An unintended contact of the rear of an aircraft's fuselage with the ground during a takeoff or landing.

In aviation, a tailstrike is an event in which the rear empennage of an aircraft strikes the runway. This can happen during takeoff of a fixed-wing aircraft if the pilot pulls up too rapidly, leading to the rear end of the fuselage touching the runway. It can also occur during landing if the pilot raises the nose too aggressively. This is often the result of an attempt to land nearer to the runway threshold.

A tailstrike is physically possible only on an aircraft with tricycle landing gear; with a taildragger configuration, the tail is already on the ground. Some aircraft which require a high angle of attack on takeoff are fitted with small tailwheels ( Concorde and the Saab Draken) or tailskids ( Diamond DA20) to mitigate the effect of tailstrikes.

Tailstrike incidents are rarely dangerous in themselves but the aircraft must be thoroughly inspected and repairs may be difficult and expensive if the pressure hull is involved. Inadequate inspections and improper repairs to damaged airframes after a tailstrike have been known to cause catastrophic structural failure long after the tailstrike incident following multiple pressurization cycles .
