DD Form 314, Preventive Maintenance Schedule and Record is a form used to schedule regular preventive item maintenance and to document the maintenance actions performed. All maintenance recorded on the form must be performed on a time or mileage basis. As an example, the schedule should be used to record maintenance done every 2 months, every 1000 miles or after every 2000 hours of operation.
The latest edition of the form - sometimes incorrectly referred to as the DA Form 314 - was released by the Department of Defense (DoD) in December 1953 with all previous editions being obsolete. A fillable DD Form 314 is available for download below or can be found through the Executive Services Directorate website.
