The No Fly Maintenance Record has which form number?

• A. 4377B
• B. 4378B
• C. 4369A
• D. 4376A

Answer: (B)

When an aircraft cannot be flown due to an unairworthy condition, a formal No Fly status is used to document that restriction and the steps needed to resolve it. The form designated for this No Fly record provides a single, recognizable document in the maintenance file that shows the aircraft must not be operated until corrective action is completed and approved. The form number assigned for this No Fly maintenance record is 4378B, which is why that option is the correct choice. This form is distinct from other document numbers that cover different maintenance records, such as routine releases or inspections, so they would not be used to record a No Fly status.
