DA Form 2408-19-2: T700 Series Turbine Engine Analysis Check – The DA Form 2408-19-2, officially titled the T700 Series Turbine Engine Analysis Check Record, is a critical U.S. Army maintenance document used for tracking and analyzing the performance of T700 series turbine engines. These engines power key U.S. Army helicopters like the UH-60 Black Hawk and AH-64 Apache. This form supports aviation maintenance programs by helping maintainers monitor engine health, detect performance degradation early, and ensure mission readiness.
What Is DA Form 2408-19-2?
DA Form 2408-19-2 is a semi-permanent historical record specifically designed for T700 series turbine engines (such as the T700-GE-700, -701, and variants). It records data from Health Indicator Test (HIT) checks and related engine performance analyses.
The form captures parameters like date, engine time, torque settings, temperatures, altitudes, NG (gas generator) speeds, and remarks. This data allows trends in engine performance to be tracked over time, supporting predictive maintenance and compliance with Army regulations.
Official Reference: For use of this form, see DA PAM 738-751 (Functional Users Manual for the Army Maintenance Management System – Aviation). The proponent agency is DCSLOG (now part of broader Army logistics structures).
Purpose of the T700 Series Turbine Engine Analysis Check Record
The primary purpose of DA Form 2408-19-2 is to document engine analysis checks (primarily HIT checks) to:
- Monitor engine performance degradation (e.g., increases in Turbine Gas Temperature/TGT at given power settings).
- Identify trends that may indicate the need for maintenance, compressor washes, or deeper inspections.
- Provide a historical record for aircraft logbooks, transfers, and depot-level activities.
- Support safety, readiness, and compliance with Army aviation maintenance standards.
HIT checks, often performed as a first-flight-of-the-day verification at a stabilized torque (commonly around 60% TQ for some procedures), help determine if the engine is operating within acceptable margins. A failing or trending HIT check may trigger a Maximum Power Check or further troubleshooting.
This form works alongside related records like:
- DA Form 2408-19-3 (Engine Component Operating Hours Record)
- DA Form 2408-16-1 (History Recorder for T700 modules)
- Oil Analysis Logs (DA Form 2408-20)
Key Fields and How to Complete DA Form 2408-19-2
The form includes header information and a tabular log for multiple checks:
- Block 1: Nomenclature
- Block 2: Engine Model
- Block 3: Engine Serial Number
- Blocks 4–12: Various identifiers including aircraft details, torque references, etc.
- Data Columns (typical): Date, Serial Number (if applicable), Time, °C (temperature), ALT (altitude), NG%, ACT (actual), TTV, ETF, Remarks.
Entries must be accurate, legible, and made by authorized personnel per DA PAM 738-751. Remarks often note any anomalies, corrective actions, or references to related maintenance forms. Samples of completed forms are available in DA PAM 738-751 (e.g., Figure 4-17).
Pro Tip for U.S. Army Aviation Units: Always cross-reference with the specific Technical Manual (e.g., TM 1-2840-248-23 for T700 engines) for HIT check procedures and baseline data.
Importance in U.S. Army Aviation Maintenance
T700 engines are workhorses in Army aviation. Proper use of DA Form 2408-19-2 helps:
- Prevent unexpected power loss or failures.
- Optimize engine life and reduce overhaul costs.
- Maintain compliance during Aviation Resource Management Surveys (ARMS), safety inspections, and audits.
- Support data-driven decisions for component tracking and modular maintenance.
Accurate records are essential for aircraft transfers, deployments, and depot returns.

Best Practices and Common Questions
- Perform HIT checks per aircraft/Engine TMs and record promptly.
- Trend data over time — gradual TGT increases can signal compressor fouling or other issues.
- Retain forms as part of the aircraft historical file per DA PAM 738-751.
- Integrate with modern tools where available, but manual forms remain key for many units.
FAQ:
- Is it only for Black Hawk? No — used across T700-powered platforms.
- How often? Typically daily or per flight schedule/TM requirements.
- Who fills it? Qualified maintenance personnel or crew chiefs.
For the most current instructions, consult the latest version of DA PAM 738-751 and your unit SOPs. Proper use of this form directly contributes to keeping Army aircraft safe and mission-ready.
