For how long is a DTA (Daily Technical Assessment) valid?

The Daily Technical Assessment (DTA) is essential for ensuring the operational readiness of the aircraft. The validity period of 72 hours means that once a DTA is completed, the assessment remains applicable for that duration, reflecting the condition of the aircraft and its systems. This timeframe allows maintenance personnel and pilots to rely on the assessment for daily operations, providing a clear window during which the aircraft is deemed fit for flight.

This 72-hour validity is crucial as it balances the need for thorough inspections with operational efficiency, allowing routine flight operations while emphasizing the importance of aircraft readiness and safety. Regular assessments continue to ensure any changes in equipment status or discrepancies are identified and addressed promptly if the aircraft is operational beyond this timeframe.
