How long must completed FCF checklists be retained?

Retention of completed FCF (Functional Check Flight) checklists for a duration of 6 months is crucial for several reasons. Primarily, this time frame allows organizations to maintain an effective record of inspections and operational compliance following flight operations. Keeping these checklists for six months provides ample opportunity to review and assess performance trends, conduct operational audits, and ensure adherence to maintenance protocols.

Additionally, a six-month retention period strikes a balance between operational efficiency and regulatory compliance, allowing organizations to respond to any inquiries or issues that may arise related to the aircraft's operational history within that time frame. After six months, the data may be less critical, but having these records available helps maintain a clear and accountable maintenance culture.

Other options such as shorter retention periods may not provide adequate time for thorough reviews or resolutions of issues that may surface after a flight, while retaining records indefinitely could lead to storage challenges and complicate data management efforts. Thus, six months serves as an optimal standard for retaining FCF checklists.
