SECTION 1: PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) Q1 – Q10
══════════════════════════════════════
Question 1 of 50
PFC Evans is preparing his M1083 FMTV for a scheduled logistics run and must verify
the vehicle's operational status before turning the ignition key. According to TM
9-2320-365-10, what specific PMCS interval must he perform at this time?
. Perform the Before (B) PMCS inspection to identify any faults prior to mission
A
execution. ✓ CORRECT
B. Perform the During (D) PMCS inspection to monitor vehicle performance while
operating.
C. Perform the After (A) PMCS inspection to document deficiencies that occurred
during the mission.
D. Perform the Weekly PMCS inspection to ensure long-term serviceability of the
vehicle.
orrect Answer: A
C
Rationale: Per TM 9-2320-365-10, the Before (B) PMCS is mandatory prior to operating
the vehicle to ensure it is fully mission capable. The most tempting wrong answer is the
During (D) inspection, which is performed while the vehicle is in motion, not prior to
,starting the engine. Always remember that "Before" means before the key is turned for
the mission.
Question 2 of 50
SGT Morris discovers a leaking brake line on his M915A3 during a routine check and
needs to annotate this fault on the DA Form 5988-E. What status symbol must he use to
properly classify this safety hazard?
. Annotate the fault with a slash (/) to indicate a minor deficiency requiring routine
A
scheduling.
B. Annotate the fault with an X to indicate a deadline deficiency that makes the vehicle
NMC. ✓ CORRECT
C. Annotate the fault with a diagonal line (-) to indicate the vehicle is operational but
needs repair.
D. Annotate the fault with a circle (O) to indicate the fault requires immediate
supervisory attention.
orrect Answer: B
C
Rationale: An X status symbol on DA Form 5988-E denotes a deadline deficiency that
renders the vehicle non-mission capable (NMC), and a brake leak falls strictly into this
category. The slash (/) is a common trap used for non-deadline faults, but applying it to
a brake hazard violates safety of use messages. When in doubt about braking or
steering faults, always default to the most restrictive deadline symbol.
Question 3 of 50
SPC Reynolds is driving an M1083 FMTV across soft sand and notices the tires losing
traction while the Central Tire Inflation System (CTIS) is set to the wrong terrain mode.
,To what setting must he switch the CTIS to increase the tire footprint and improve
traction?
. Switch the CTIS to the Highway (HWY) setting to maintain maximum tire pressure on
A
sand.
B. Switch the CTIS to the Cross-Country (CC) setting for moderate off-road terrain
pressure.
C. Switch the CTIS to the Mud/Sand (MS) setting to decrease tire pressure and increase
footprint. ✓ CORRECT
D. Switch the CTIS to the Emergency (EMER) setting to completely deflate the tires for
maximum grip.
orrect Answer: C
C
Rationale: The Mud/Sand (MS) setting on the CTIS lowers tire pressure sufficiently to
increase the tire footprint, providing maximum flotation on soft surfaces. The
Cross-Country (CC) setting is a common trap because it reduces pressure, but not
enough for deep sand, which can lead to the vehicle becoming bogged down.
Remember that the Emergency setting is strictly for run-flat scenarios at low speeds,
not for routine off-road traction.
Question 4 of 50
A driver is conducting an air brake system check on an M915A4 tractor and the
pressure gauge reads 60 PSI after the vehicle has been sitting overnight. According to
the TM, what is the correct action regarding this air pressure reading?
. Start the engine immediately and let it idle to build pressure without pumping the
A
brakes.
B. Pump the brake pedal repeatedly to exhaust the remaining air and reset the system.
, . Drain the air tanks completely to remove moisture before attempting to start the
C
vehicle.
D. Do not start the vehicle until the air system is repaired, as the pressure is below the
90 PSI minimum. ✓ CORRECT
orrect Answer: D
C
Rationale: Army TM standards require the air brake system to maintain a minimum of
90 PSI overnight; reading 60 PSI indicates a massive air leak that must be repaired
before operation. Pumping the brake pedal is a common trap that wastes remaining air
and completely ignores the underlying leak hazard. During PMCS, always verify static air
pressure matches the TM minimum before turning the key.
Question 5 of 50
SSG Davis is supervising the loading of an M1120 HEMTT and notices several cargo
straps with frayed edges and knots. According to FM 4-01.5, what actions must be
taken regarding these tie-down devices?
. Remove the damaged straps from service immediately and replace them with
A
serviceable ones. ✓ CORRECT
B. Mark the damaged straps with red tape and use them only for lighter cargo loads.
C. Tie a knot in the frayed section to prevent further unraveling before using the strap.
D. Apply duct tape over the frayed sections to reinforce the strap for the current mission.
orrect Answer: A
C
Rationale: FM 4-01.5 dictates that any tie-down device with frayed edges, knots, or
defects must be immediately removed from service and replaced. Taping over frayed
sections or tying knots are common field-expedient traps that severely compromise the
