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?

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.

A maintenance unit has two identical aircraft; one is mission capable, and the other is non-mission capable (NMC) due to a faulty transmitter. A high-priority mission requires a second aircraft, but the replacement transmitter will not arrive in time. The commander authorizes the removal of the working transmitter from the NMC aircraft to install on the mission-required aircraft. What is this maintenance action called, and what is a key documentation principle?

Answer: Cannibalization; requires documentation of the part removal on the forms of the donor aircraft.

This action is defined as cannibalization: the removal of a serviceable part from one piece of equipment to install it on another to restore it to operational condition. All such actions must be meticulously documented in the maintenance records (e.g., DA Form 2408-13-1) of both the donor and receiving aircraft to maintain accountability and record integrity.

What component controls the pitch of rotor blades in helicopters?

Answer: Pitch control mechanism.

The pitch control mechanism, often involving the swashplate and associated linkages, is specifically designed to adjust the angle of attack (pitch) of helicopter rotor blades. This adjustment is crucial for generating lift, controlling thrust, and maneuvering the aircraft in flight.

Which component is responsible for generating electrical power in an Army helicopter?

Answer: Generator

In an Army helicopter, the generator is the primary component responsible for generating electrical power while the engine is running. It converts mechanical energy from the engine into electrical energy to operate the aircraft's various electrical systems, including avionics, lighting, and other onboard equipment. While batteries provide power for starting and emergencies, the generator sustains the electrical load during flight.

What is the correct grounding procedure before connecting electrical GSE to an Army aircraft?

Answer: Attach the aircraft ground strap before connecting any electrical equipment

The aircraft must be properly grounded before connecting any electrical ground support equipment to prevent electrostatic discharge damage.

A maintenance team is performing a 100-hour inspection on a UH-60. They note several scheduled maintenance items that are due at different intervals (e.g., daily, 40 hours, monthly). Which form is specifically designed to list these special inspections and time-change components to ensure they are tracked and completed?

Answer: DA Form 2408-18, Equipment Inspection List

DA Form 2408-18, Equipment Inspection List, is used to record and track special inspections and components that have a scheduled replacement or inspection interval different from the aircraft's primary inspection schedule. This form ensures these critical, time-sensitive tasks are not overlooked.

Which system is essential for maintaining rotor blade speed?

Answer: Governor system

The governor system in a helicopter is crucial for automatically maintaining a constant rotor RPM (revolutions per minute) regardless of changes in engine power or aerodynamic loads. This steady rotor speed is vital for stable flight, efficient lift generation, and preventing dangerous fluctuations.

In the modern Army Aviation maintenance environment, what is the official, primary source for approved maintenance procedures, technical manuals, and checklists?

Answer: Interactive Electronic Technical Manuals (IETMs) accessed via an approved electronic device.

The Army has transitioned from paper manuals to Interactive Electronic Technical Manuals (IETMs) as the primary, authoritative source for maintenance information. IETMs provide up-to-date, interactive procedures and are the standard for field and sustainment-level maintenance.

Which of the following scenarios would necessitate sending an entire AH-64 Apache helicopter to a Depot-level maintenance facility?

Answer: The aircraft has sustained significant structural damage in a hard landing, requiring airframe realignment.

Depot-level maintenance handles the most complex and extensive tasks, including major structural repairs, overhauls, and complete rebuilds of aircraft and components that are beyond the capabilities of Field (AVUM) and intermediate (AVIM) maintenance. Scheduled inspections and component replacements are typically handled at the AVUM or AVIM levels.

Why is it important to update maintenance documentation regularly?

Answer: To maintain accuracy and compliance

Regularly updating maintenance documentation is critical to ensure its accuracy, reflecting current procedures, equipment configurations, and regulatory requirements. Accurate documentation is essential for effective troubleshooting, consistent maintenance practices, and demonstrating compliance during audits, thereby enhancing safety and operational integrity.

Why is incident reporting important?

Answer: To prevent future accidents

Incident reporting is crucial because it provides valuable data for analyzing the root causes of accidents and near-misses. By understanding why incidents occur, organizations can implement corrective actions, revise procedures, and improve safety protocols, thereby preventing similar events from happening in the future.

Which form is used to record faults found on GSE during PMCS?

Answer: DA Form 5988-E

DA Form 5988-E (Equipment Inspection and Maintenance Worksheet) is used to record faults discovered during PMCS on ground equipment.

What is the purpose of anodizing aluminum aircraft components in Army aviation?

Answer: To create a hard, corrosion-resistant aluminum oxide layer on the component surface

Anodizing creates a controlled, hard aluminum oxide layer on the component surface that is highly resistant to corrosion and provides an excellent base for subsequent paint adhesion.

What action is required when aviation GSE reaches its scheduled service interval?

Answer: Perform required services per the applicable TM regardless of operational tempo

Scheduled services must be performed at prescribed intervals per the TM to maintain equipment reliability and safety.

A maintenance supervisor needs to check the status of a critical part ordered for a non-mission-capable aircraft. Which modern logistics information system would they primarily use to track the requisition from order placement to delivery?
