AAC Scheduled Maintenance Inspections — Questions and Answers

Question 1: Which DA form lists an aircraft's scheduled inspections and component changes along with when each is next due?

DA Form 2408-13-1
DA Form 2408-18 (Correct answer)
DA Form 2408-12
DA Form 2408-15

Correct answer: DA Form 2408-18

The DA Form 2408-18 Equipment Inspection List tracks scheduled inspections and their next due hours or dates.

Question 2: Under a phased maintenance system, what happens to the complete inspection requirement?

It is performed in full at every flight
It is replaced entirely by operator preflight checks
It is divided into smaller segments performed at set flight-hour intervals (Correct answer)
It is deferred to depot level

Correct answer: It is divided into smaller segments performed at set flight-hour intervals

Phased maintenance breaks the full inspection into phases so the aircraft is out of service for shorter periods.

Question 3: An aircraft is in its scheduled phase maintenance inspection. What readiness status is it normally reported as?

Fully mission capable
Partially mission capable
Not mission capable – supply
Not mission capable – maintenance (Correct answer)

Correct answer: Not mission capable – maintenance

An aircraft undergoing scheduled maintenance cannot perform its mission and is reported NMCM.

Question 4: Which publication series contains the detailed preventive maintenance and phase inspection checklists for a specific Army aircraft?

The aircraft -23 series TMs and associated PMD/PMS checklists (Correct answer)
AR 600-20
FM 3-04 only
DA PAM 25-30

Correct answer: The aircraft -23 series TMs and associated PMD/PMS checklists

Aviation unit maintenance procedures and inspection requirements are found in the aircraft's -23 series maintenance manuals and checklists.

Question 5: A crew chief finds a defect during an inspection that makes the aircraft unsafe to fly. Which status symbol is entered?

Red diagonal
Red horizontal dash
Red X (Correct answer)
Circled red X

Correct answer: Red X

A red X indicates the aircraft is in an unsafe condition and must not be flown until corrected.

Question 6: Which publication is the primary functional users manual for The Army Maintenance Management System – Aviation (TAMMS-A)?

AR 95-1
DA PAM 738-751 (Correct answer)
TM 9-1300-200
AR 385-10

Correct answer: DA PAM 738-751

DA PAM 738-751 prescribes TAMMS-A forms, records, and status symbol procedures.

Question 7: After a technical inspector verifies the corrective action for a red X fault, what does that inspection accomplish?

It allows the fault to be transferred to the historical record
It converts the fault to a red diagonal
It automatically schedules the next phase
It clears the red X so the aircraft may return to flight status (Correct answer)

Correct answer: It clears the red X so the aircraft may return to flight status

Red X faults require inspection and sign-off by a qualified technical inspector before the aircraft is released.

Question 8: Which status symbol indicates that an inspection, component change, or MWO is due but not completed, yet the aircraft may still be flown?

Red horizontal dash (Correct answer)
Red X
Red diagonal
Circled red X

Correct answer: Red horizontal dash

A red horizontal dash marks an incomplete required action that does not ground the aircraft.

Question 9: A hard landing is reported by the flight crew. What type of inspection is required?

Phase inspection
Special inspection (Correct answer)
Preventive maintenance daily
Calendar inspection

Correct answer: Special inspection

Unscheduled events such as hard landings, overspeeds, and overtorques trigger special inspections in the -23 manual.

Question 10: Who may authorize flight of an aircraft under a circled red X condition?

Any rated aviator assigned to the unit
The crew chief alone
A person designated in writing by the commander (Correct answer)
The supply sergeant

Correct answer: A person designated in writing by the commander

A circled red X permits limited flight only when an individual appointed by the commander authorizes it.

Question 11: Which inspection is typically performed by the operator before each mission using the -10 operator's manual or -CL checklist?

Phase inspection
Preflight inspection (Correct answer)
Overhaul inspection
Depot inspection

Correct answer: Preflight inspection

Operators conduct the preflight inspection per the -10 or -CL before flight.

Question 12: An aircraft exceeds the allowable tolerance for a scheduled inspection without an approved extension. What is its status?

Red diagonal
Red horizontal dash
No symbol required
Red X (Correct answer)

Correct answer: Red X

Exceeding an inspection interval beyond its tolerance grounds the aircraft until the inspection is completed.

Question 13: Which form is used to record faults that are deferred or carried forward rather than corrected immediately?

DA Form 2408-14-1, Uncorrected Fault Record (Correct answer)
DA Form 2408-17, Aircraft Inventory Record
DA Form 2408-16, Aircraft Component Historical Record
DA Form 2408-5, Equipment Modification Record

Correct answer: DA Form 2408-14-1, Uncorrected Fault Record

Deferred faults are transferred to the DA Form 2408-14-1 so they remain tracked until corrected.

Question 14: After certain phase work or major component replacement, what flight may be required before the aircraft returns to normal service?

Ferry flight
Training flight
Maintenance test flight (Correct answer)
Air assault flight

Correct answer: Maintenance test flight

A maintenance test flight by a qualified maintenance test pilot verifies systems after specified maintenance.

Question 15: Which status symbol indicates a known material defect that is not serious enough to ground the aircraft?

Red X
Red diagonal (Correct answer)
Circled red X
Red horizontal dash

Correct answer: Red diagonal

A red diagonal identifies a minor fault that does not make the aircraft unsafe for flight.

Question 16: In what color ink are status symbols entered on TAMMS-A forms?

Black
Blue
Green
Red (Correct answer)

Correct answer: Red

Status symbols are entered in red so they stand out on the forms.

Question 17: Which form records an aircraft's flight hours, landings, and other per-flight data entered by the crew?

DA Form 2408-12, Army Aviator's Flight Record (Correct answer)
DA Form 2408-12 only for maintenance test flights
DA Form 2408-20, Oil Analysis Log
DA Form 2408-15, Historical Record for Aircraft

Correct answer: DA Form 2408-12, Army Aviator's Flight Record

The DA Form 2408-12 captures aviator flight data used to track hours toward scheduled inspections.

Question 18: Why is accurate flight-hour recording critical to scheduled maintenance?

It determines pilot pay grade
It is used only for fuel accounting
Phase and component inspections are triggered by accumulated hours (Correct answer)
It replaces the need for calendar inspections

Correct answer: Phase and component inspections are triggered by accumulated hours

Hour-based inspections and component retirement times depend on accurate flight-hour data.

Question 19: Which program uses periodic fluid samples to detect internal wear in engines and gearboxes between scheduled inspections?

Army Oil Analysis Program (Correct answer)
Army Safety Program
Army Physical Security Program
Command Supply Discipline Program

Correct answer: Army Oil Analysis Program

AOAP analyzes oil samples to identify abnormal wear before failures occur.

Question 20: Which form tracks components with finite service lives or retirement times?

DA Form 2408-13
DA Form 2408-17
DA Form 2408-12
DA Form 2408-16 (Correct answer)

Correct answer: DA Form 2408-16

The DA Form 2408-16 Aircraft Component Historical Record tracks time-limited components.

Question 21: An aircraft has been parked and not flown for an extended period. What type of scheduled inspection may still come due?

Hard landing inspection
Calendar-based inspection (Correct answer)
Overspeed inspection
Lightning strike inspection

Correct answer: Calendar-based inspection

Some inspections are due by calendar days regardless of flight hours flown.
