What is DD Form 314?
DD Form 314, titled “Preventive Maintenance Schedule and Record,” is a standardized form established in December 1953. It serves as both a scheduling tool and a historical record for periodic preventive maintenance services on military equipment, vehicles, and systems.
The form tracks maintenance performed on a time or mileage basis (e.g., quarterly, every 1,000 hours, or every 5,000 miles) and records periods when equipment is not mission capable (NMC).
Purpose of DD Form 314 in U.S. Military Maintenance
The primary purpose of DD Form 314 is to ensure equipment remains in a high state of readiness through systematic preventive maintenance. It helps:
- Schedule upcoming services in advance.
- Document completed maintenance actions.
- Track Not Mission Capable (NMC) time due to maintenance or supply issues.
- Maintain historical records for accountability and audits.
- Support overall equipment readiness reporting in Army and DoD units.
Key Sections of the DD Form 314
The form is double-sided with specific fields for identification and maintenance tracking:
- Front Side: Registration Number, Administration No., Nomenclature, Model, Assigned To, monthly calendar blocks for scheduling and recording services (with symbols like Q for Quarterly, M for Monthly).
- Reverse Side: Used for recording NMC time, odometer/hour meter readings, remarks, and disposition details.
How to Fill Out DD Form 314: Step-by-Step Guide?
