How long is a fax copy of a lost medical certificate valid for flight operations?

A fax copy of a lost medical certificate is valid for flight operations for a period of 60 days. This timeframe allows pilots to continue flying while they await the issuance of a replacement medical certificate. It's important for pilots to maintain compliance with medical certification requirements, and having this provisional validity helps ensure safety and regulatory adherence. This 60-day period provides adequate time for the processing and issuance of a new certificate without interrupting flight operations.
