The AME is one who is responsible to issue a certificate whether the aircraft is healthy to fly or carry the passengers or even carry cargos from source to destination. Not only aircraft need its maintenance but its individual parts need to be tested and repaired or assembled or even replaced, if required. The different parts of the aircraft which needs to be inspected on regular basis are engines, base of aircraft, airframe, fuel system, control system, communication system etc.
All the different parts of the aircraft need to be inspected and maintained but there are some parts in the aircraft which need little more attention as compared to others. For example the engine of the aircraft as it is responsible for taking off from source to land on the destination. There are some parts in the engine which are visible to human eyes i.e. some parts of the engine cannot be inspected by the human eyes. For this a device called borescopes is used. Borescope is one of the types of optical device used for visual inspection. It is a device by which the visual inspection of the aircraft engines. There are different types of borescopes which are available. All the distinct parts of the aircraft engine can be inspected visually. So that if is there any kind of fault can be inspected and the necessary steps can be taken to overcome the fault.
In this way borescope play an important role in the inspection of different parts of engines which are inaccessible by any other means. Thus borescope is one of the important devices which are used for aircraft maintenance. As the engine of the aircraft is inspected and maintained, so the other parts of the aircraft can be inspected and maintained by different means. For the inspection of the communication or control system this device is optional.
Keeping in mind the security of the passengers and the cargos, the aircraft maintenance cannot be considered as an ordinary task. It is so vital and crucial task and must be governed and done either by the experts or under the supervision of experts.
