300 Plus Questions & Answers
Part 1: PMCS (Preventive Maintenance Checks and
Services) & Vehicle Maintenance
Q1: What does "deadlined" mean on equipment inspection forms?
A: Vehicle cannot be operated until repaired. Deadlined equipment is
unsafe or incapable of performing its mission.
Q2: What does a diagonal dash ( / ) indicate on DA Form 5988-E or
2404?
A: A material defect other than a deficiency. These defects do not
prevent safe operation and do not require immediate corrective action.
Q3: What does an "X" indicate on equipment inspection forms?
A: A deficiency that makes the vehicle inoperable or deadlined. Vehicles
with an "X" cannot be operated until the issue is corrected.
Q4: What does a circled "X" mean on a PMCS form?
A: Equipment has a deficiency but may be operated under set
limitations.
Q5: What is the primary purpose of the PMCS process?
A: To inspect, record, clean, service, and repair equipment to ensure it
remains safe, reliable, and mission ready.
Q6: What are the three PMCS intervals?
A: Before (B), During (D), and After (A) operations.
Q7: When should after-operation PMCS be conducted?
,A: Immediately after vehicle operation to identify issues that occurred
during use.
Q8: Who is responsible for performing PMCS?
A: The assigned operator.
Q9: What form is commonly used to record equipment faults?
A: DA Form 5988-E (Equipment Inspection and Maintenance Worksheet).
Q10: What are the three categories of fluid leaks?
A:
• Class I leak: Seepage of fluid (wetness or discoloration) not great
enough to form drops
• Class II leak: Seepage great enough to form drops, but not
enough to cause dripping
• Class III leak: Seepage great enough to form drops that drip
during inspection
Q11: Which fluid should be checked with the engine running?
A: Transmission fluid.
Q12: What does "cold" tire pressure mean?
A: Before driving more than 1 mile.
Q13: What is the minimum acceptable brake lining thickness on
most military tactical vehicles?
A: 1/8 inch.
Q14: What is the minimum tread depth for steer axle tires?
A: 4/32 inch.
Q15: When checking battery electrolyte levels, the fluid should
cover the plates by:
A: Approximately 1/2 inch.
,Q16: How many categories of faults are there on a DA Form 2404?
A: 3 categories: minor, major, and deadlined.
Q17: What is the recommended timeframe for correcting minor
faults?
A: Within 24 hours or before the next mission, whichever comes first.
Q18: What are the categories in a PMCS table?
A: Item Number, Interval, Item to be checked or serviced, Procedure, and
Equipment not ready/available if.
Q19: During a PMCS inspection, you find the coolant level is below
the cold fill line and the engine is warm. What should you do?
A: Wait until the engine cools, then add coolant. Never remove a hot
radiator cap.
Q20: You discover a small amount of oil on the ground under the
drain plug. What is the correct action?
A: Tighten the drain plug and mark the leak. Minor leaks that don't affect
fluid levels can be noted for correction after mission.
Q21: During After (A) PMCS, you discover turn signals on your
HMMWV are not working. What DA Form do you use to report this?
A: DA Form 2404.
Q22: The "B" in PMCS stands for:
A: Before (operations).
Q23: The "D" in PMCS stands for:
A: During (operations).
Q24: What color is standard antifreeze in military vehicles?
A: Green.
, Q25: What does CTIS allow the driver to do on a HEMTT?
A: Change tire pressure from the cab (Central Tire Inflation System).
Q26: What is the purpose of dispatch procedures?
A: Ensure vehicles are authorized, safe, and documented for use.
Q27: What document authorizes a driver to operate military
vehicles?
A: OF 346 or military driver's license.
Q28: What is considered an operator-level maintenance task?
A: Adding fluids and tightening loose items.
Q29: Why is documentation important in PMCS?
A: To track faults, repairs, and readiness status.
Q30: You are conducting Before (B) PMCS on an M1083 FMTV. You
find a small amount of engine oil on the ground. The correct action
is:
A: Tighten the drain plug and mark the leak.
Part 2: DA Form 5987-E & Documentation
Q31: What is the purpose of DA Form 5987-E?
A: To keep a record of motor equipment usage and documentation of
fuel usage.
Q32: What are the sections of DA Form 5987-E?
A: Header and equipment data, Dispatch information, Qualifications, and
Equipment usage data.
Q33: What is DA Form 5988-E used for?
