Pilot error
Encyclopedia
Pilot error is a term used to describe the cause of an accident involving an airworthy aircraft
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

Due diligence
"Due diligence" is a term used for a number of concepts involving either an investigation of a business or person prior to signing a contract, or an act with a certain standard of care. It can be a legal obligation, but the term will more commonly apply to voluntary investigations...

 by an aircraft operator during the performance of his/her duties.

Usually in an accident deemed due to "pilot error", the pilot in command (Captain) made the error unintentionally. However, an intentional disregard for a standard operating procedure (or warning) is still considered pilot error, even if the pilot's actions justified criminal charges.

An aircraft operator (airline or aircraft owner) is generally not held accountable for an incident that is principally due to a mechanical failure of the aircraft unless the mechanical failure occurred as a result of pilot error.

The pilot may be declared to be in error even during adverse weather conditions if the investigating body deems that the pilot did not exercise due diligence. The responsibility for the accident in such a case would depend upon whether the pilot could reasonably know of the danger and whether he or she took reasonable steps to avoid the weather problem. Flying into a hurricane (for other than legitimate research purposes) would be considered pilot error; flying into a microburst

A microburst is a very localized column of sinking air, producing damaging divergent and straight-line winds at the surface that are similar to, but distinguishable from, tornadoes, which generally have convergent damage. There are two types of microbursts: wet microbursts and dry microbursts...

Told by ATC to hold over a sparsely populated area away from the airport (with, as a result, very few lights on the ground visible to act as an external reference) while they dealt with the problem, the distracted flight crew did not notice the plane losing height and the aircraft eventually struck the ground in the Everglades

 was due to the failure of the rudder which was caused by "unnecessary and excessive rudder pedal inputs" on the part of the co-pilot who was operating the aircraft at the time. Attorneys for the co-pilot, who was killed in the crash, argue that American Airlines' pilots had never been properly trained concerning extreme rudder inputs. The attorneys also claimed that the rudder failure was actually caused by a flaw in the design of the Airbus A300
