A comparative quantitative research on Brazilian and American Examiners' and Inspectors' disapproval rates of pilot flight proficiency checks for Personnel Licensing
Résumé
The contracting States of the Convention on International Civil Aviation (1944) shall ensure the validity of issued licences; therefore, flight proficiency check is used to grant its privileges, maintain holder's competency, and shall be conducted by personnel authorized by the Licensing Authority: Examiners (outsourced) or Inspectors (employees). This study compared the disapproval rates of pilots in flight proficiency checks among Examiners and Inspectors from Brazil and The United States of America from 2014 to 2019, focusing on initial exams for license issuance of private pilot, commercial pilot, air transport pilot, as well as instrument and flight instructor ratings. The need for this comparison arose from the inspectorate's anecdotal perception of Authority’s lack in safety culture, standardization, oversight, and Inspectors' pilot training, associated to low disapproval rates on checks. To investigate this assumption, data were collected, classified, and analyzed using the Two Proportions Z-test. The Brazilian rates were 0.53% vs. 1.94%; p<0.01 (General) and 0.75% vs. 2.77%; p<0.01 (Personnel Licensing), while the American rates were 23.10% vs. 24.37%; p<0.022 (Personnel Licensing); consequently, the comparison between countries resulted in p<0.001. This study revealed regulatory noncompliance; thus, proposed corrections, regulations revision, Inspectors’ pilot training, and standardization, as defences or enhancements opportunities towards Safety and Standards implementation to respond to the practical drift and prevent accidents. Ultimately, the Proficiency Check Dashboard was developed and proposed as a data-driven tool for oversight prioritization and intensification on Examiners, as a practical result of this study.
