Abstract

Boeing 737-900 ER maintenance in Indonesia emphasizes timely, efficient routines to minimize risks. Using the Critical Path Method (CPM), the analysis calculates the Turn Around Time (TAT) for C05-Check maintenance. The CPM results estimate a TAT of 20.47 days (rounded to 20 days), while the company's data shows 21.73 days (rounded to 22 days), indicating a 2-day difference. This discrepancy highlights potential areas for improving maintenance efficiency. The TAT efficiency for the maintenance process is calculated at 0.057%. Optimizing mechanic workload based on this analysis can enhance turnaround times and ensure aircraft safety and operational scheduling. Accurate TAT predictions are vital for balancing maintenance quality with airline efficiency, making CPM a valuable tool in operational planning and resource allocation. Continued comparison with company data ensures maintenance practices remain precise, reducing unexpected delays and maintaining flight safety standards.

Abstract

Burning Hours is the one of  policy in scheduling aircraft maintenance. With the burning hours the operator could performed aircraft maintenance before the due time. Burning Hours is indeed beneficial for flight operators to maintain the stability of the safety of the aircraft operation. Using the quantitative analysis method with the sample data’s from two aircraft, found that the burning hours affects to Burning Hours Cost loss for every aircraft meintenance activity. The value of Burning Hours Cost Loss and Potential Lost per Day needs to be considered by operators in scheduling maintenance activities, because it is possible that Burning Hours cannot be avoided in aircraft operation. Based on the data processing,  the  value of burning hours cost lost is not more than limit of potential lost per day.  However it should also be considered if burning hours applied continuously will increase maintenance cost. Therefore, between maintenance planning department and the operation department should keep good coordination to minimize the burning hours cost loss. Keywords: Planning, Maintenance, Burning Hours
