AAC - Army Aviation Maintenance Program Scheduled Maintenance Inspections Questions and Answers — Questions and Answers
Question 1: A UH-60L Black Hawk is due for a Phase Maintenance Inspection (PMI) based on accumulated flight hours. According to Army Aviation Maintenance Program doctrine, what is the primary objective of this scheduled inspection?
- To perform a complete overhaul of the aircraft, replacing all time-limited components regardless of their condition.
- To systematically inspect designated sections of the aircraft, identify and correct faults, and return a fully mission capable aircraft to the unit. (Correct answer)
- To exclusively address pilot-reported discrepancies that were recorded on the DA Form 2408-13-1.
- To upgrade aircraft avionics and weapon systems in accordance with the latest modification work orders (MWOs).
Correct answer: To systematically inspect designated sections of the aircraft, identify and correct faults, and return a fully mission capable aircraft to the unit.
The primary objective of a Phase Maintenance Inspection (PMI) is to systematically inspect the aircraft in-depth to find and fix problems, ensuring it is returned to the operational unit in a fully mission capable status. While some components may be replaced, it is not a complete overhaul, and it addresses more than just pilot-reported issues or upgrades.
Question 2: During a scheduled maintenance inspection, a technician discovers a cracked transmission mounting bolt. The necessary replacement part is not available through the standard supply system in a timely manner. To restore the aircraft to mission capable status quickly, the maintenance officer authorizes the removal of a serviceable bolt from another aircraft that is awaiting parts for a different, non-mission-critical issue. What is this process called?
- Cannibalization
- Controlled Exchange (Correct answer)
- Standard Repair
- Materiel Deficiency Reporting
Correct answer: Controlled Exchange
Controlled exchange is the authorized removal of serviceable components from an unserviceable, but economically repairable, end item for immediate reuse in restoring a like item to a mission-capable condition when the part is not available from the supply system in time. Cannibalization, by contrast, is the unauthorized removal of parts or involves stripping parts from an item designated for disposal.
Question 3: Which of the following inspections is a recurring, scheduled event based on a predetermined interval of accumulated flight hours, calendar days, or operating hours?
- Special Inspection
- Pre-flight Inspection
- Periodic Inspection (Correct answer)
- Conditional Inspection
Correct answer: Periodic Inspection
Periodic Inspections (which include Phase Maintenance Inspections) are comprehensive inspections conducted at regular, predetermined intervals specified by the aircraft manufacturer and Army regulations. Special/Conditional inspections are unscheduled and are performed after specific incidents like a hard landing or severe turbulence. A pre-flight inspection is conducted before every flight.
Question 4: A maintenance team is preparing for a 500-hour phase inspection on an AH-64D Apache. The team leader is developing the inspection schedule. In addition to the tasks listed in the Phase Maintenance Inspection checklist, which of the following must also be accounted for, potentially doubling the time required for the maintenance event?
- Daily fluid and lubricant servicing.
- Refueling and defueling procedures.
- Special inspections, calendar inspections, and safety messages.
- Routine aircraft washing and cleaning. (Correct answer)
Correct answer: Routine aircraft washing and cleaning.
A standard PMI checklist provides man-hours for the basic phase tasks. However, the total time for the inspection is often significantly increased by the need to complete additional requirements such as special inspections, calendar-based inspections, Aviation Safety Action Messages (ASAMs), and Aviation Maintenance Action Messages (AMAMs) that are also due.
Question 5: What is the primary purpose of a Preventive Maintenance Daily (PMD) inspection?
- To perform in-depth diagnostics on all aircraft systems.
- To check for and service fluid levels only.
- To ensure all scheduled component replacements are completed.
- To conduct visual examinations and operational checks to ensure the aircraft is safe for the day's mission. (Correct answer)
Correct answer: To conduct visual examinations and operational checks to ensure the aircraft is safe for the day's mission.
The Preventive Maintenance Daily (PMD) inspection is accomplished before the first flight of the next mission day. It consists of visual examinations and operational checks to determine if the aircraft can safely perform its assigned mission. It is a routine check, not an in-depth inspection or a time for major component replacement.
Question 6: According to DA PAM 738-751, which form is typically used as a worksheet by technical inspectors (TIs) during the completion of scheduled maintenance inspections like a phase or periodic inspection?
- DA Form 2408-13-1, Aircraft Maintenance and Inspection Record
- DA Form 2408-13-3, Aircraft Technical Inspection Worksheet (Correct answer)
- DA Form 2408-19-3, Engine Component Operating Hours Record
- DA Form 2405, Maintenance Request
Correct answer: DA Form 2408-13-3, Aircraft Technical Inspection Worksheet
DA Form 2408-13-3 serves as the Aircraft Technical Inspection Worksheet. Technical inspectors use this form to document their findings during scheduled and unscheduled maintenance inspections. The faults are then transferred to the appropriate maintenance record, such as the DA Form 2408-13-1.
