Abstract

This study aims to analyze the catastrophic structural failure experienced by a UPS McDonnell Douglas MD-11F (N259UP) cargo aircraft on November 4, 2025, in Louisville, Kentucky. The investigation focused on the detachment of the number 1 engine due to engine pylon failure during takeoff. Through metallurgical analysis and a review of the NTSB investigation report, fatigue cracking in the forward mount fitting was found to be the primary cause of the engine detachment. The results revealed gaps in routine inspection methods for aging aircraft. The study concluded that transitioning to Structural Health Monitoring technology and fleet modernization are crucial risk mitigation measures for the global air cargo industry.

Abstract

Emergency diesel generator is a very important system in every industry including the airport industry because this system supports the electricity of important equipment when a blackout occurs. in the emergency diesel generator system, there is a battery as a starter for the diesel engine. if the battery capacity decreases, the diesel generator will not be able to start the engine, therefore in the emergency diesel generator system, regular battery maintenance is needed to maintain system reliability. in this journal, preventive maintenance on the battery will be explained, especially on the emergency diesel generator system battery. one indicator of decreased capacity in the battery is an increase in its internal resistance value. in preventive battery maintenance, analyzing the increase in internal resistance can be a reference for replacing a new battery.

Abstract

The advent of low-cost loitering munitions has revolutionized modern warfare,creating a profound economic imbalance between offensive and defensive capabilities. In the Middle East, the deployment of Iran's Shahed-136 drone against Israel's Iron Dome defense system serves as a prime example of a "cost-imposing" strategy in asymmetric warfare. Objective: This study aims to quantify the economic disproportion between the production and deployment costs of the Shahed-136 drone and the operational costs of the Iron Dome system. It explores how this cost ratio impacts long-term national defense budgets andstrategic sustainability. Methodology: This study uses a qualitative-descriptive approach supported by comparative economic modelling. Data are synthesized from defense budget reports, estimates of the Shahed-136 manufacturing costs, and the unit cost of the Iron Dome Tamir interceptor missile. The analysis uses the Cost- xchange Ratio (CER) to evaluate the economic efficiency of both sides. Results: The study's findings reveal a sharp economic asymmetry, with a single Shahed-136 estimated to cost between $20,000 and $50,000, depending on configuration, while a single Tamir interceptor missile costs approximately $40,000 to $100,000, depending on configuration. When factoring in "saturation attacks" (ordrone swarms), defense costs increase exponentially, not only through missile expenditure but also through the economic disruption caused by airstrike warnings and collateralinfrastructure damage if interceptions fail. Conclusion: The study concludes that while Iron Dome remains tactically effective in saving lives, its current economic trajectory is unsustainable against the threat of low-cost, mass-produced drones. The study suggests that to maintain strategic stability, the defense framework must transition to lower-cost interception technologies, such as directed energy weapons (lasers/Iron Beam), to neutralize the economic advantage currently held by offensive drone platforms.
