How should major leaks be approached during bleed down checks?

When conducting bleed down checks on the C-130J, major leaks should be approached by addressing them immediately. This is crucial because major leaks can significantly impact the operability and safety of the aircraft. They can lead to a loss of pressure and efficiency in the system, which is vital for the performance of the Auxiliary Power Unit (APU) and associated systems.

Immediate action allows for timely repairs or adjustments to be made, preventing further complications or potential accidents. Additionally, addressing leaks promptly helps ensure compliance with safety regulations and operational standards, which is critical for maintaining mission readiness and overall aircraft integrity.

In contrast, ignoring leaks or postponing their inspection can lead to worsened conditions, increased repair costs, or unsafe operational environments, underscoring the necessity for an immediate response to major leaks. Monitoring minor leaks or scheduling repairs for the future does not address the urgency required for major leaks, which could compromise aircraft performance and safety.
