In October, Ameco Beijing successfully completed a structure sampling inspection on an Air China's A340 aircraft, which is another major step forward immediately after Ameco Beijing conducted the modification of fuselage structural change at FR80-FR87 on this aircraft.

Structure sampling inspection is also named as special detailed inspection on aircraft structure, aiming at grasping the structure damage status of contemporary off-line aircraft and mapping out a better maintenance plan.

This structure sampling inspection involving over 500 job cards covers such areas as aircraft wing interior, landing gear junction and vertical empennage skin and requires fluorescent destructive test, X-ray test and NDT to aircraft structure, engine and landing gear.

Ameco Beijing ever performed structure sampling inspection on one of Lufthansa's Boeing747 during its 5D Check. Boeing and Airbus have big differences in terms of structure and system. Therefore, if structure sampling inspection is conducted, Airbus aircraft requires more workload, more special tools and more disassembly items.
