Description

Aviation safety inspection oversight apparatus

The present invention relates to an aviation safety inspection supervision apparatus.

Aviation safety impairment refers to anything that affects or has the potential to affect aviation safety in relation to the operation of aircraft, in addition to aircraft accidents and sub-accidents, and aviation safety hazards or hazards refer to aircraft accidents, aircraft sub-accidents, or aviation safety obstacles. It refers to situations, conditions, or physical and human factors that may or may not contribute to the expansion of the possibility of occurrence.

Aviation safety information refers to processing, organizing, and analysis of aviation safety data for use for safety management purposes, and aviation safety inspection means that the safety management system of the air transport business operator is approved and is operating in the approved state. Tell the procedure.

In order to continuously maintain and manage the safe navigation system of air transport operators, each country's airworthiness/operation authorities secure aviation safety operation by conducting intensive inspections in the form of special inspection supervision for matters requiring regular inspection and extensive verification. .

The regular inspection supervision and special inspection of the existing air transport service provider is carried out using a checklist that stipulates the items subject to inspection for both operations (OP) and airworthiness (AW). However, the regular inspection supervision of the existing air transport service provider does not use past inspection data such as the unique organization, operation history, operation control, and aircraft maintenance history of each air transport service provider, but uniformly establishes an annual inspection plan and performs it mechanically. In addition, regardless of the risk of inspection target items that affect aircraft operation or airworthiness, the aviation safety inspector visits and inspects each air transport service provider according to the annual regular inspection and supervision plan.

From the perspective of regular inspection and supervision, the frequency of regular inspection and supervision by aviation supervisors is increasing as the number of aircraft in operation continues to increase, and in terms of special inspection and supervision, the frequency of aviation safety failures increases as the number of flights for each aircraft owned by an air carrier increases. The increase in aviation safety supervision resources for aviation safety inspection are more demanded. Furthermore, since aviation safety inspections are carried out for air transport companies after an aircraft accident or a quasi-accident occurs, the effect of preventing accidents in advance cannot be expected. Therefore, there is an urgent need for an efficient aviation safety inspection supervisory device.

However, Patent Document 1 compares and analyzes the differences between international aviation safety regulations and domestic aviation laws, manages implementation status in real time, and builds a database of related data so that appropriate measures can be taken, and a series of business analysis and processing processes are automated with a program. As a result, it has the effect of using resources as efficiently as possible, but it does not provide a solution to how to efficiently perform aviation safety inspections in the form of regular inspection supervision and special inspection supervision.

Patent Document 2 is a database storing aviation safety fault reports, a program that reviews the report contents of the database stored in the database and inputs the review results, a program that sets a numerical value for calculating a risk index, and an aircraft that is the basis for calculating the risk index. A program that receives flight number information in real time, a program that calculates the risk index with the value reviewed by the administrator, a database that stores the risk index calculated by the program, a program that displays the calculated risk index, and safety fault and risk index. Disclosed is an aviation safety indicator management system, characterized in that it includes a program showing statistical data about Korea. Patent Document 2 is capable of accumulating, analyzing and predicting information on accidents, quasi-accidents, and safety fault data occurring in air navigation, control, and airports, but how to efficiently perform aviation safety inspections in the form of regular inspection supervision and special inspection supervision. It has not been able to present a solution as to whether it should be done.

<Example 1>

1 is a diagram showing a schematic diagram of an inspection target item 100 for aviation safety inspection. Referring to FIG. 1, the item 100 to be inspected for aviation safety may largely have an engineering system classification system of a system 110, a subsystem 120, a unit element 130, and a unit element attribute 140. Each system 110 may have a subsystem 120, each subsystem 120 may have a unit element 130, and each unit element 130 may have a unit element attribute 140 value. have. Each system 110, subsystem 120, unit element 130, and unit element attribute 140 may be singular or plural. As described above, by classifying the inspection target item 100 into similar items of the system 110, the subsystem 120, the unit element 130, and the unit element attribute 140, the aviation safety inspection supervision item can be viewed clearly.

According to the present invention, since the inspection target item 100 to which the unit element attribute 140 is assigned for each unit element 130 is used for aviation safety inspection, more detailed aviation safety inspection supervision is possible. For example, if there are 73 unit elements 130, it is possible to inspect and supervise only 73 unit elements 130, but if 6 more unit element properties 140 are added, a total of 438 unit element properties 140 will be added. On the other hand, since it is possible to supervise the aviation safety inspection, it is possible to specifically identify which attributes 140 of the specific tasks (unit elements) of which sector (system) and which department (subsystem) of the air transport service provider should be monitored and taken action. .

2 shows an example of an item to be inspected 100 according to an embodiment. In FIG. 2, the system 110 is the largest classification unit for aviation safety inspection, and may have six systems of organization management, operation, operation control, aircraft maintenance operation, cabin operation, ground operation, and dangerous goods management. Each system 110 may have a sub-system 120 that is dependent on it. For example, the organization management system 110 may have a sub-system 120 of safety management, operation management, and airworthiness management. Each subsystem 120 may have a unit element 130, for example, the safety management subsystem 120 is a safety program, maintenance work continuous analysis and supervision system, reliability program, safety policy, safety risk management, safety It may have a unit element 130 of guarantee and safety promotion. In addition, each unit element 130 may have a unit element attribute 140, for example, may have six items of responsibility, authority, procedure, control, procedure measurement, and interface. This unit element attribute 140 implies an intrinsic aspect that should be intensively supervised in the process of supervising each unit element 130.

According to the present invention, in performing aviation safety inspection, the inspection period is not uniformly determined, but inspection and supervision can be performed by evaluating the risk level considering the frequency and severity of nonconformity for the items subject to aviation safety inspection in the past. It can be used more efficiently.

The risk grade of the item to be inspected 100 may be determined in consideration of the probability and severity. Here, the frequency of occurrence is calculated using the average and standard deviation of the nonconformity incidence rate divided by the number of nonconformity occurrences for each item to be inspected (100) as a result of the inspection and supervision of the air transport service provider during the past certain period. It can be normalized as in Equation 1.

[Equation 1]

-Number of nonconformity occurrences: (x _i ), i=1, 2,… , n

-Total number of inspection supervision: (y _i ), i=1, 2,… , n

-Nonconformity incidence rate: (z _i = x _i /y _i ), i=1, 2,… , n

-Mean value of incidence of nonconformity: m = (z ₁ + z ₂ +… + z _n )/n

-Standard deviation of the incidence of nonconformity:

If the nonconformity incidence rate of the item to be inspected (100) in the previous year is less than or equal to the average value of the nonconformity incidence calculated by Equation 1 plus the standard deviation, the incidence frequency is “1st grade” and exceeds the value obtained by adding 1 times the standard deviation to the average value. If the value is less than the sum of two times, it can be classified as “2nd grade”, and if it is more than the average value plus two times the standard deviation, it can be classified as “3rd grade”.

The severity is classified as “A grade” for items to be inspected (100) of low importance, “B grade” for normal items, and “C grade” for high items by referring to the survey results of aviation safety experts or the amount of damage. I can.

The risk of the item to be inspected 100 may be determined in consideration of the probability and severity as shown in Equation 2 below.

[Equation 2]

Risk Grade = Probability & Severity

FIG. 3 shows a risk calculation table 200 for determining an inspection cycle for an item to be inspected 100 based on a risk in consideration of the frequency and severity of occurrence. According to FIG. 3, each area of the risk classification system can be classified into a low-risk group, a normal-risk group, and a high-risk group according to the risk of the item to be inspected 100. For example, risk level “1A”, “2A”, “1B” area is low risk group, risk level “1C”, “2B”, “3A” area is moderate risk group, risk level “2C”, “3C”, “3B” Can be defined as a high-risk group.

4 shows an example of the number of times of inspection and the number of occurrences of nonconformity for the item to be inspected (100). 4 shows the number of times the regular inspection and supervision were performed annually from 2017 to 2019 for the “safety program”, “continuous analysis of maintenance work”, and “reliability program”, which are the items subject to inspection (100), and the number of occurrences of nonconformities. For example, in the case of the “Continuous Maintenance Analysis” category, the total number of inspections in 2019 was 10, whereas the number of nonconformities was 2, and the case of the “Reliability Program” showed that 1 nonconformity occurred for 2 inspections in 2018. .

5 shows an example of calculating the degree of risk for the item to be inspected (100). It can be seen that the rate of nonconformity in 2019 under the “Continuous Maintenance Analysis” category was 0.2, and the rate of nonconformity in the “Reliability Program” category was 0.5 in 2018. From this, the frequency of occurrence can be determined by obtaining the average and standard deviation of the nonconformity incidence rate for each item to be inspected from 2017 to 2019, and then comparing it with the nonconformity incidence rate in 2019.

Since the severity of the item to be inspected 100 can be determined using the results of a pre-determined expert survey, the risk levels for “safety program”, “continuous maintenance analysis”, and “reliability program” in FIG. 5 are 1A and 2B, respectively. , Was set as 1C. In Fig. 5, "safety program" is classified into low-risk group, and "maintenance work continuity analysis" and "reliability program" are classified into normal risk group. Therefore, the inspection and supervision cycle of "maintenance work continuity analysis" and "reliability program" compared to "safety program" Can be set to be shorter. That is, the inspection subject item 100 having a high risk can be efficiently allocated aviation safety supervision resources by shortening the inspection supervision cycle and the inspection subject item 100 having a low risk extending the inspection supervision cycle. Here, the inspection and supervision cycle may be a regular inspection and supervision cycle, and the inspection and supervision cycle can be determined in various ways, such as in units of 3 months or 6 months, depending on the level of risk.

In this embodiment, a risk classification system is shown when the frequency of occurrence is divided into three values of 1 to 3, and the severity is divided into three values of A to C. However, the range of values of the frequency of occurrence according to the embodiment B If the range of the severity value is different, the number of areas in the risk classification system may also change.

6 shows a schematic diagram of an aviation safety inspection supervisory device.

Referring to FIG. 6, the aviation safety inspection supervisor 300 includes an inspection target storage unit 310, a nonconformity occurrence count input unit 320, a nonconformity occurrence rate identification unit 330, an occurrence frequency determination unit 340, and a severity storage unit ( 350), may include a risk calculation unit 360 and an inspection period providing unit 370.

The inspection object storage unit 310 divides the inspection object item 100 into a system 110, a subsystem 120, a unit element 130, and a unit element attribute 140, and is stored in a one-to-one or one-to-many format in a relational database. Can be saved.

The number of nonconformity occurrences input unit 320 receives the number of occurrences of nonconformity generated as a result of the inspection for each item to be inspected 100 for a certain period of time. For example, when there is a past inspection history for each item to be inspected 100, only items marked as nonconformity are counted and entered into the system, or the system may automatically extract only the number of occurrences of nonconformity.

The nonconformity occurrence rate grasping unit 330 calculates the nonconformity occurrence rate by dividing the number of nonconformity occurrences that occurred as a result of checking each item to be inspected 100 for each airline operator for a certain period by the number of safety inspections conducted during the period. The number of safety inspections can be extracted by automatically counting the number of safety inspections previously conducted in the system, or can be manually input.

The occurrence frequency identification unit 340 normalizes the number of nonconformity occurrences for each item to be inspected (100) as a result of inspection and supervision by the air transport service provider, using the average of the nonconformity occurrence rate divided by the total number of inspection and supervision, and the standard deviation, and then the nonconformity in the previous year. If the incidence rate is less than the average value of the nonconformity incidence rate plus the standard deviation, the incidence frequency is “Class 1”, and if the incidence rate exceeds the value obtained by adding 1 times the standard deviation to the average value and is less than the value plus 2 times, the occurrence rate is “Class 2”; If it is more than the average value plus 2 times the standard deviation, it can be saved or printed in the system as “3rd grade”.

The severity storage unit 350 refers to the result of a survey by an aviation safety expert, and is a relational type with “A grade” for the items to be inspected (100) of low importance, “B grade” for normal items, and “C grade” for high items. It can be stored in the database in advance.

The risk calculation unit 360 combines the calculation result of the occurrence frequency determination unit 330 and the value stored in the severity storage unit 350, and the “1A”, “2A” and “1B” areas are “low risk group” and “1C”. The “, “2B” and “3A” areas can be stored or output in the system as “normal risk group”, “2C”, “3C”, and “3B” are “high risk group”.

The inspection period providing unit 370 provides a short inspection period for the inspection target item 100 with a high risk based on the risk group obtained by the risk calculation unit 360, and the inspection target item 100 with a low risk is the inspection cycle. I can provide it for a long time. Here, the inspection period may be a regular inspection period determined for each inspection target item 100, and the inspection supervision period may be set in units of 3 months or 6 months according to the degree of risk.

As described above, the aviation safety inspection supervisory device according to the present invention does not uniformly determine the inspection period when performing aviation safety inspection, but inspects and supervises the inspection by evaluating the risk level considering the occurrence frequency and severity of nonconformity for each of the items to be inspected in the past. Since the cycle can be provided, aviation safety supervision resources can be used more efficiently.

<Example 2>

The occurrence of an aviation safety obstacle once or twice in an air transport service provider does not lead to an aircraft accident or a quasi-accident. However, it can be said that items with a high frequency of aviation safety obstacles in the past are more likely to lead to aircraft accidents or semi-accidents. Therefore, in the case of selecting items with a high frequency among past aviation safety obstacles and managing the items to be inspected 100 corresponding thereto in the form of a special inspection, the possibility of an aircraft accident or a quasi-accident can be prevented in advance.

7 shows aviation safety obstacle data 400 according to an embodiment. Aviation safety obstacle data 400 does not correspond to an aircraft accident or quasi-accident, but refers to an obstacle that affects or is likely to affect aviation safety in relation to the operation of an aircraft. ).

In Figure 7, the safety obstacle indicator 410 is runway departure, runway invasion, loss of control, aerial collision, terrain collision, collision on the ground, abnormal runway contact, injuries during operation, emergency oxygen use, fire/smoke, failure/defect, induction It shows that it can be selected as mis-entry, altitude/departure, take-off stop, hard landing, and manual flight/incompetence. In addition, it shows that the hazard factors 420 that cause the runway departure safety obstacle indicator 410 can be classified into unsafe landing approach, bad weather, non-compliance with operating procedures in bad weather, and aircraft performance.

8 shows a correlation between the safety failure indicator 410 and the item to be inspected 100 according to an embodiment. The correlation between the safety obstacle index 410 and the inspection target item 100 may be obtained by analyzing an expert survey or the damage amount of the past safety obstacle index 410, and these may be mapped in advance. At this time, the unit element 130 of the item to be inspected 100 may be mapped. 8 shows the mapping relationship between the safety fault indicator 410 and the unit element 130 among the items to be inspected 100, but in some cases, the unit element 130 among the hazard factors 420 and the items to be inspected 100 ) Can also be used.

Using FIG. 8, when an air transport business operator reports the aviation safety error data 400, the inspection target item 100 corresponding to the aviation safety error data 400 is mapped in advance, so that the correct inspection target item 100 is selected. I can recommend it.

That is, after analyzing the frequency of the aviation safety fault data 400 and extracting the aviation safety fault data 400 that frequently appear among them, the pre-mapped inspection target item 100 is recommended to the aviation safety supervisor for special inspection. It can be implemented to do. For example, after analyzing the aviation safety fault data 400 for the past 2-3 months and extracting the aviation safety fault data 400 with a high frequency among them, a predetermined item to be inspected (100) is presented to the aviation safety supervisor. Then, the aviation safety inspector can carry out the aviation safety inspection in the form of a special inspection in the current month. These special inspections prevent aircraft accidents or semi-accidents in that, in addition to the regular inspection and supervision performed on a regular basis, inspection activities are performed with a focus on the safety-vulnerable part based on the aviation safety fault data 400 that has occurred for each aviation operator. There is an effect that can be prevented in advance.

The mapping unit 520 may store the items to be inspected 100 that affect the safety failure indicator 410 or the hazard factor 420 stored in the safety failure storage unit 510 in a one-to-one or one-to-many format in a relational database. have. More specifically, the unit element 130 of the item to be inspected 100 may be used for mapping.

The safety fault information input unit 530 is a configuration that can receive aviation safety fault information data that is obligated by the air transport service provider, and if a safety fault occurs to the air transport service provider through wired or wireless communication, the safety fault indicator 410 and hazard factors You can select 420 and receive the input.

The recommendation unit 540 may recommend a special inspection target item of an air transport service provider by linking the result input to the safety fault information input unit 530 and the mapping unit 520. Here, the recommendation unit 540 may select a high occurrence frequency among safety fault information that has occurred for a certain period of time, and automatically select the item to be inspected 100 mapped thereto, and output it in the system.

More specifically, when the air transport service provider inputs the aviation safety fault data 400, the system may recommend the closest inspection target item 100 from the mapping unit 520. The aviation safety inspection supervisory apparatus 300 collects the aviation safety fault data 400 that occurred in the previous month or the previous month, extracts the items with high frequency among them, and through the mapping unit 520, the items subject to inspection ( 100) can be recommended.
