A tailstrike is when the tail hits the runway during high speed actions like take off or landing.
It's very few probable that it could end in a fatal accient, but the damage caused with a wrongly made repair can cause progressive damage increasing that can end in a potential fatal accident risk in the future.
Accidents by tailstrike sequels
- In Japan Airlines flight 123, a tailstrike that damaged back-pressure bulkhead lead to a wrong repair that caused it's explossion and the accident 7 years later.
- 22 years before China Airlines flight 611, the involved Boeing 747 did a tailstrike in Hong Kong and China Airlines manteinance made a temporary repair, but the permament one was never made and as a consequence the aircraft splitted in the air.
