DA Form 2408-16-2: Auxiliary Power Unit Record (Download) – U.S. Army maintenance document used to track the historical data, installation, removal, operating hours, starts, and maintenance of Auxiliary Power Units (APUs) and their sub-components on Army aircraft.
This form supports the Army Maintenance Management System – Aviation (TAMMS-A) as outlined in DA PAM 738-751. It ensures safety, regulatory compliance, accurate life tracking, and proper scheduling of maintenance for APUs, which provide essential power for aircraft systems when main engines are off or during ground operations.

What Is DA Form 2408-16-2?
DA Form 2408-16-2, titled Auxiliary Power Unit and Component Record, was released by the Department of the Army on March 1, 2014. It serves as a dedicated historical record for APUs and associated components.
Unlike the related DA Form 2408-16 (Aircraft Component Historical Record) or DA Form 2408-16-1 (History Recorder, Component, Module Record), this form specifically addresses APUs, which often use starts and operating hours as primary tracking metrics.
It forms part of the permanent aircraft equipment log assembly and helps maintain configuration control, especially in systems like GCSS-Army Enterprise Aviation (EAVN).
Purpose of the Auxiliary Power Unit and Component Record
The primary purpose of DA Form 2408-16-2 is to provide a permanent, auditable record of:
- APU installation and removal history
- Cumulative starts and operating hours
- Sub-component tracking (e.g., for time-change or condition-based items)
- Significant historical events, maintenance actions, and modifications
- Data needed for replacement scheduling and overhaul projections
Accurate records support flight safety, prevent exceeding component life limits, facilitate inspections, and ensure compliance with technical manuals and airworthiness directives.
Key Sections and How to Fill Out DA Form 2408-16-2
According to the form layout and DA PAM 738-751 guidelines:
- Blocks 1-5: Basic identification including Model, Nomenclature, Serial Number, Part Number, and Next Higher Assembly (NHA) S/N.
- Block 6: Tracks starts and operating hours with calculations for meter readings at removal/installation, totals since install, previous counts, and historical totals.
- Block 7: Detailed table for components/sub-components, including nomenclature, part/NSN, serial numbers, starts/hours since install/removal, previous data, replacement due, and component life limits.
- Block 8: Significant Historical Data — for notes on maintenance, repairs, modifications, or other critical events.
Always use pencil or authorized entries per TAMMS-A procedures. Round hours appropriately and leave non-applicable spaces blank. Refer to the latest DA PAM 738-751 for detailed preparation instructions.
Who Uses DA Form 2408-16-2?
This form is primarily used by:
- Army Aviation units (e.g., helicopter and fixed-wing maintainers)
- Aviation maintenance technicians and crews
- Supply and logistics personnel managing aircraft components
- Depot-level repair facilities
It is required for aircraft equipped with APUs, such as various UH, AH, and CH series helicopters.
Importance in Army Aviation Maintenance
Proper use of DA Form 2408-16-2 contributes to:
- Safety: Prevents operation of components beyond safe limits.
- Readiness: Supports accurate forecasting of maintenance and part replacements.
- Accountability: Provides traceability for warranty, modifications (MWO), and historical analysis.
- Transition to Digital: Feeds into systems like GCSS-Army for automated tracking.
Errors or missing records can lead to grounding aircraft or compliance issues, as highlighted in various maintenance advisories.
