AAC Preventive Maintenance Checks Questions and Answers

Question 1

In Army Aviation, preventive maintenance checks are broadly categorized based on who performs them and their level of detail. What are the two primary categories of these checks?

Accepted Answer

Aircrew and Maintenance Personnel Checks

Answer

Army Aviation maintenance doctrine divides Preventive Maintenance Checks (PMCs) into two main groups: those performed by the aircrew (pre-flight, thru-flight, post-flight) and more in-depth, technical checks performed by qualified maintenance personnel (e.g., Preventive Maintenance Daily and Phased Maintenance Inspections).

Question 2

A crew chief has just completed and signed off the Preventive Maintenance Daily (PMD) on a UH-60M. Before the first flight of the day, what is the pilot's specific responsibility regarding the aircraft's condition?

Accepted Answer

To perform a separate and distinct pre-flight inspection per the operator's manual.

Answer

Even after maintenance personnel complete a PMD, the pilot-in-command is always required to conduct a thorough pre-flight inspection as outlined in the aircraft's technical manual. This is a final, independent verification by the operator to ensure the aircraft is safe for the intended flight.

Question 3

Which of the following is a key objective of the Preventive Maintenance Daily (PMD) inspection?

Accepted Answer

To verify the airworthiness of the aircraft and identify faults before the first flight of the day.

Answer

The PMD is a systematic inspection performed by maintenance personnel to ensure the aircraft is mission-capable and airworthy. Its primary goal is to detect and correct any faults before the day's flight operations begin, establishing a baseline of readiness.

Question 4

A CH-47F is due for its 400-hour Phased Maintenance Inspection (PMI). The maintenance platoon sergeant is briefing the team. What is the defining characteristic of a PMI that they should emphasize?

Accepted Answer

It is a comprehensive inspection divided into sequential segments to minimize aircraft downtime.

Answer

A Phased Maintenance Inspection (PMI) is a thorough, in-depth inspection that is broken down into numbered phases or packages. This approach allows significant maintenance to be performed in manageable segments, reducing the total time the aircraft is non-mission capable compared to one single, massive inspection event.

Question 5

According to Army maintenance doctrine, who holds the ultimate responsibility for ensuring the unit's Preventive Maintenance Checks and Services (PMCS) program is properly established and executed?

Accepted Answer

The Unit Commander

Answer

While pilots, maintenance officers, and crew chiefs all have critical roles, the unit commander is ultimately responsible for all aspects of the unit's operations, including the proper execution, training, and enforcement of the maintenance and PMCS program to ensure readiness.
