Carefully inspect various parts of the aircraft
After the arrival of an aircraft, mechanics perform pre-flight inspection to prepare for the next flight and repair troubles occurring during flight, which are reported by pilots and cabin attendants.
During pre-flight inspection, they check aircraft conditions of the previous flight, the aircraft exterior for dents or scratches, fuel spillage, wear and tear of tires, whether abrasion of brakes is within the normal range, etc., and other various check items.
