Identification of Contributing Factors Impacting Aircraft Engine Component Repair Instructions Development

Abstract

The development of repair instructions for aircraft engine components is complex and vulnerable to errors during development, affecting the completion and delivery on a timely manner. The purpose of this project was to identify contributing errors affecting the technical data development for a specific aircraft component family, categorize them, and identify the main offender. Three different databases were reviewed to collect findings, focusing on active tasks from March 2022 to October 2022. Findings collected on each database were distributed into five categories directly related to the technical document development: Background Research, Preliminary Design Review, Repair Substantiation, Final Design Review, and Final Validation. The Background Research category was found to be the main area of opportunity, with 13 findings out of a total of 30 (43%). Two initiatives were implemented to mitigate risks: controlled list of part numbers and documented best practices shared among team members. Key Terms ⎯ Aerospace, aircraft engine components, quality, rework.
