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.
Mechanics use their five senses to the maximum and do not miss even the slightest abnormal change, such as differences in engine sound. If there are traces of bird strike or lightning strike, they carry out a special inspection.
If there is trouble, they accurately pinpoint the cause, and swiftly repair it. They perform maintenance work daily, bearing in mind to provide passengers with a comfortable flight, as well as ensure the safety of the aircraft.
After completing pre-flight inspection and repair, mechanics report the conditions to pilots and cabin attendants of the next flight, sign the log book as evidence of guaranteeing airworthiness, and hand the log book to the pilots. The safety baton is passed on from the mechanics to crew, and safety in operations of each and every flight is ensured.
