DA Form 2408-16-1: History Recorder Guide (2026) – U.S. Army aviation units rely on precise maintenance documentation to ensure aircraft safety, readiness, and compliance. DA Form 2408-16-1, titled History Recorder, Component, Module Record, plays a critical role in tracking usage and historical data for engines, components, and modules—particularly in systems like T700 series engines.
This article explains the form’s purpose, proper use, completion instructions, and importance in Army aviation maintenance programs. Download the official form here: DA Form 2408-16-1 PDF.
What Is DA Form 2408-16-1?
DA Form 2408-16-1 (October 1991 edition) is a specialized U.S. Army form used to record historical counts and data for history recorders, components, and modules. It supports the Army Maintenance Management System – Aviation (TAMMS-A) as outlined in DA PAM 738-751.
It primarily tracks cycle counts (such as Low Cycle Fatigue or LCF counts) and operating hours for components that use a history recorder. These recorders monitor stress and usage on critical engine modules more accurately than simple flight hours.
Key Details:
- Proponent Agency: DCS, G-4 (Deputy Chief of Staff, G-4).
- For Use With: DA PAM 738-751.
- Related Forms: DA Form 2408-16 (Aircraft Component Historical Record), DA Form 2410 (Component Removal/Repair/Install), and others in the 2408 series.
Purpose of the History Recorder Component Module Record
The form ensures accurate tracking of component life limits, especially for items where usage is measured by cycles, temperature, or other indices rather than (or in addition to) operating hours. This data supports:
- Determining remaining useful life and overhaul schedules.
- Compliance with time-between-overhaul (TBO) and retirement life requirements.
- Accurate entries on DA Form 2410 during removal, repair, or installation.
- Safety and reliability of aircraft systems, particularly turbine engines.
It is essential for major components like engines and their modules, where a dedicated history recorder device logs operational data.
When to Use DA Form 2408-16-1?
Use this form for:
- Engines or modules equipped with history recorders (e.g., T700 series).
- Tracking installation/removal of history recorders or associated components.
- Recording cumulative historical counts when replacing recorders or modules.
- Maintaining permanent records that travel with the component.
It is not a general aircraft log but a specific module/component life tracker. Always refer to the applicable aircraft technical manuals (TMs) and DA PAM 738-751 for guidance.
How to Fill Out DA Form 2408-16-1: Step-by-Step Instructions?
Follow block-by-block preparation instructions from DA PAM 738-751 and technical bulletins. Use black ballpoint pen for entries.
Header Information (Blocks 1-5)
- 1. MODEL: Enter the model of the engine or major component.
- 2. ENG S/N: Engine serial number.
- 3. NOMENCLATURE: Full name/description of the component/module.
- 4. P/N: Part number.
- 5. S/N: Serial number of the specific item.
Block 6: History Recorder Data and Counts
This section records multiple lines for historical counts (LCF-1, LCF-2, Time/Temp Index, Operating Hours):
- Enter History Recorder S/N.
- Record Reading at Removal and Reading at Installation.
- Calculate Line 3 Minus 2 (difference in readings).
- Add Previous Counts to get Total Component Counts.
Repeat for additional lines as needed. When replacing a history recorder, complete entries for the old one and start new entries for the replacement.
Block 7 and Additional Sections
Continue with subsequent history recorder entries if more space is required. Use continuation sheets if the form fills up.
Reverse Side: Significant Historical Data (Block 14)
Use this area for narrative entries, such as:
- Overhaul (O/H) or history counts at last depot replacement.
- Significant maintenance events, repairs, or inspections.
- Any other data affecting component life.
Best Practices and Common Procedures
- Recorder Replacement: Update all related DA Forms 2408-16-1. Carry forward totals accurately.
- Integration with DA Form 2410: Data from this form feeds directly into component removal/install records.
- Accuracy: Double-check calculations for counts and hours, as errors affect maintenance schedules and safety.
- Retention: These records stay with the component/module and are part of permanent historical files.
- Digital Transition: While paper forms remain in use, many units integrate data into GCSS-Army (Global Combat Support System-Army) for aviation.
Always consult the current version of DA PAM 738-751 for detailed examples and updates.
Why Proper Use Matters for U.S. Army Aviation?
Accurate completion of DA Form 2408-16-1 helps:
- Prevent premature or overdue component replacements.
- Support mission readiness and flight safety.
- Ensure auditability and compliance during inspections.
- Maintain accountability for high-value aviation assets.
Errors in historical tracking can lead to grounding aircraft or compromising safety margins.
