All aircraft operators have specific maintenance procedures that are designed to establish the operational status of an aircraft. These procedures or Aircraft Maintenance Programs are developed to satisfy their operational requirement for the long run.
Planning of never exceed periods for each check is necessary to comply with regulatory authorities and for the safety of flight. The never exceed period may be specified in calendar time or flying hours or cycles of a mixture.
A typical maintenance check cycle will comprise of transit or pre-flight checks daily, weekly, and monthly checks. These checks are performed at a specific interval. Each check is a little deeper than the previous one. These checks are planned in such a way that they can be performed during home base visits. Let us go through each one of these checks individually in details.
Let us take an example of haul aircraft, it may have one daily check and several transits check a day; you can read how AI helps in transit flight making the process less time-consuming.
A check: This check starts from thorough visual inspection and operations of major airframe and engine systems. This is performed approx. every 500- 800 flight hour. It may be done overnight on the ramp or in a hangar.
B check: It includes a complete A check and is a more detailed check of systems. It is performed approx. every 6 to 9 months. The scheduled maintenance can be planned such that B checks are incorporated into successive A checks, the B checks items in reduced downtime.
C check: It includes complete A & B checks. This is performed approx. every 15 – 24 months or at a specific amount of actual flying hours as defined by the manufacturer. This check is more extensive than a B check, as most of the aircraft are inspected. The time needed to complete such a check is 1-2 weeks.
D check: The D check is the most essential. It occurs at approx. 5 -6 years for current aircraft types but the period may be reduced for the second and subsequent D checks. This check includes complete A, B, and C checks. It is a check that takes the entire aircraft apart for inspection. Such an inspection takes from 3 weeks to 2 months depending on the aircraft and the number of technicians involved.
How can AI reduce the pain of the engineering department?
The engineering department and the planning department organize and plan the entire operation of each check. But at times due to lack of workforce or any safety issue, this process exceeds the allotted time assigned to them. The study shows an aircraft in check costs approx. $60,000 a day for the airlines. AI application speeds up the operation by making it to be more time and quality.
Stages of damage detection
Computer vision begins by creating a 360-degree view of the site photographs of the aircraft in each check.
Then it marks the severity of damaged parts by scanning the breakdown of the singular 360-degree view. It scans through not only external damages but also internal damages which are not visible by human eyes. The scanning phase is to also determine the intensity of the damage.
The system undergoes double-check quality control of each aircraft after repairing or fixing the damage to analyse any human error. At each stage, it can act upon the designed task assigned to it.
The safety of employees is the highest priority of the management in the aviation industry. But due to workload, some employees tend not to follow the PPE’s which at times results in a bigger mishap.
Our cameras can detect the safety gear at the time of the operation, identifying and alarming the safety department to take further action. Our smart cameras can help in detecting fire or smoke in a hazardous condition, by setting up an alarm and warning the concerned department to act.
Another issue faced by the planning department is the allotment of the workforce and filtering them as per the highest preference of task. Our smart cameras can monitor the real-time situation and provide data that could be a key resource for the planning department to plan and optimize these resources.
