Assessment on the Causes of Delays for Scheduled Maintenance for AMO Workshops: Basis for Improving Maintenance Services

Abstract

The main objective of this study was to investigate the factors contributing to delays in the scheduled maintenance of Approved Maintenance Organization (AMO) workshops. The study aimed to understand the challenges associated with these delays and identify opportunities for enhancing maintenance services for AMO. Based on the findings, recommendations were provided to improve maintenance practices, ensuring that aircraft are maintained in optimal condition for safe and efficient flights while minimizing associated costs. This study had specific objectives, which were to gather information about the profile of the respondents, including their sex, age, years in service, position, department and AMO Company; identify the causes of delays in scheduled maintenance for Approved Maintenance Organization (AMO) workshops, encompassing factors such as planning, logistic issues (specifically customs clearances), hangarage and facilities, equipment and materials availability and status, human factors, and other potential factors; understand how these causes of delays impact maintenance services in terms of downtime and cost, focusing on the effects on the length of downtime and associated costs; and determine if there is a significant relationship between the assessed causes of delays for AMO workshops, aiming to analyze the data and identify any correlations or associations among the causes of delays. It employed a quantitative-descriptive survey method, collecting data through a survey questionnaire. The study took place at various MROs/AMOs in the Philippines, including Lufthansa Technik Philippines (LTP) in Manila and Macro Asia, SIA Engineering Philippines, Asian Aerospace Corporation, and Dornier Technology, Incorporated.
