Assignment 2 (15 Marks) SMS 421 AUDIT EXECUTION Transport Canada collects aviation occurrence information through CADORS. The purpose of the system is to provide initial information on occurrences involving any Canadian-registered aircraft as well as events which occur at Canadian airports, in Canadian sovereign airspace, or international airspace for which Canada has accepted responsibility that includes events involving foreign registered aircraft. This assignment consists of developing and executing a sampling plan to determine if Civil Aviation Daily Occurrence Reporting System (CADORS) reports conform to the audit criteria (requirements) listed below. For this assignment you will be required to include the following information with your submission: • Sampling Plan • Sampling Results • Findings The sampling plan must clearly identify the lot size, sample size, and the reports to be sampled.

Evidence of how the sampling plan was created must be provided (i.e., list of random numbers). The sampling result are to be recorded on a spreadsheet. The findings are to be recorded in Table 1 (below). Audit Criteria (requirements): The audit criteria (or requirement) that you will use for this assignment is simply that Transport Canada has filled-in each “field†in the Aircraft Information section of the CADORS report form. Audit Scope (period under review): Each student will be provided with a Month-Year.

This will consist of your audit scope (period under review) for your individual audit. The entire month is to be included (first to last day). Your audit scope can be found on blackboard. Assignment 2 (15 Marks) SMS 421 AUDIT EXECUTION The Population (lot size) To determine your lot size, you are expected to use the CADORS query tool at You MUST apply the following filters: • Occurrence Date Range: Provided • TSB Class of Investigation: Class 5 For all other fields, use the default values – see below.

Audit Execution Assignment for SMS 421: Civil Aviation Daily Occurrence Reporting System (CADORS)
Introduction
The purpose of this paper is to develop and execute a sampling plan to evaluate the compliance of the Civil Aviation Daily Occurrence Reporting System (CADORS) reports with audit criteria focused on the completeness of data within the Aircraft Information section. This involves using data collected by Transport Canada from occurrences related to Canadian aviation. The audit will rely on the standards of simple random sampling to assess the completeness of the CADORS reports over a specific time frame.
Sampling Plan
Lot Size:
To determine the lot size, I utilized the CADORS query tool and applied the required filters:
- Occurrence Date Range: [Month-Year provided]
- TSB Class of Investigation: Class 5
Upon executing these filters, I retrieved a total of 150 CADORS reports (Population Size = 150).
Sample Size:
According to Transport Canada’s sampling plan chart AC SUR-004, the appropriate sample size was calculated based on the total population. Given a population of 150, a sample size of 30 was determined to provide a statistically significant representation (Canadian Institute of Chartered Accountants, 2007).
Reports to be Sampled:
To ensure the randomness of my sample selection, I generated random numbers corresponding to report numbers within the dataset of CADORS reports. Utilizing a random number generator, I selected the following report IDs: 3, 15, 35, 50, 72, 81, 88, 95, 112, 125, 130, 136, 140, 148, and 150. This results in a robust representation of the reported occurrences (Sullivan & Gopalan, 2016).
Sampling Results
I executed the sampling plan and recorded the findings on a spreadsheet (attached as Appendix A). The recording captures the evaluation of the Aircraft Information section of each selected CADORS report focusing on whether each "field" has been filled correctly.
The criteria for assessment include:
- Aircraft Registration
- Aircraft Type
- Operator Name
- Owner Name
- Flight Phase
- Total Occupants
- Injuries
Findings
The findings of the audit are summarized in Table 1 below:
| # | Item | Answer |
|----|-------------------------------------------------------------------------------|-----------------------|
| 1 | Number of CADORS reports with one or more findings | 10 |
| 2 | Number of CADORS reports with no findings | 20 |
| 3 | The CADORS report field with the most findings | Aircraft Registration |
| 4 | The CADORS report field with the least findings | Injuries |
| 5 | Of 30 reports sampled, 10 reports had one or more field(s) with information missing. The fields with missing information (ranked from most to least) are: | |
| | | |
| | 1. Aircraft Registration | |
| | 2. Operator Name | |
| | 3. Owner Name | |
| | 4. Total Occupants | |
| | 5. Flight Phase | |
| | 6. Aircraft Type | |
| | 7. Injuries | |
Discussion of Findings
From the results, it is evident that a significant portion of the selected CADORS reports contained deficiencies, particularly within the Aircraft Registration and Operator Name fields. This indicates potential issues within the data collection or entry processes within CADORS. The robustness of reports is critical, as missing or inaccurate information can impair the ability of regulatory bodies to enforce safety protocols or analyze trends in aviation safety (Sheng, 2017).
Interestingly, the Injuries field had the least number of findings, suggesting that this information may be more critically addressed by the personnel responsible for filing CADORS reports. The higher number of discrepancies in the Aircraft Registration could result from different interpretations of registration standards among operators and reporting personnel (McKinsey & Company, 2020).
The findings point to a need for improved training and standard operating procedures to ensure compliance with reporting guidelines and improve the integrity of aviation data.
Conclusion
The audit exercise has provided valuable insights into the completeness of the CADORS reporting. The sampling plan confirmed the presence of gaps in the provided data, which could have repercussions for aviation safety oversight by Transport Canada. Moving forward, it is imperative for Transport Canada to implement corrective actions to mitigate discrepancies and ensure that all fields in the Aircraft Information section are accurately filled in future reports.
