DA Form 2408-19: Turbine Wheel Historical Record Guid

DA Form 2408-19: Turbine Wheel Historical Record Guid – U.S. Army aviation maintenance relies on precise documentation to ensure safety, track component life, and maintain operational readiness. DA Form 2408-19, titled Aircraft Engine Turbine Wheel Historical Record, serves as a critical historical log for turbine wheels in aircraft engines. This form tracks key data such as measurements, installations, removals, temperature/overspeed events, and blade information.

What Is DA Form 2408-19?

DA Form 2408-19 is an official U.S. Army form used to maintain a permanent historical record for aircraft engine turbine wheels. It falls under the Army Maintenance Management System – Aviation (TAMMS-A) and is governed by DA PAM 738-751.

This semi-permanent record helps maintenance personnel monitor the turbine wheel’s service life, detect potential issues from abnormal operations (like excessive temperatures or overspeeds), and ensure compliance with safety and overhaul standards. It is especially important for high-stress components in turbine engines used in helicopters and other Army aircraft.

Purpose and Importance of the Turbine Wheel Historical Record

The primary purpose of DA Form 2408-19 is to create a detailed, lifelong history for each turbine wheel. This supports:

  • Safety and Reliability — Tracking diametrical measurements before/after grinding, abnormal temperature/overspeed events, and blade data helps predict failures.
  • Maintenance Tracking — Records installations, removals, reasons for removal, and engine times.
  • Life Cycle Management — Ensures components meet Time Between Overhaul (TBO) and retirement life requirements.
  • Regulatory Compliance — Required for aircraft in the Army inventory per DA PAM 738-751.

Accurate records contribute to mission readiness for units operating UH-60 Black Hawks, AH-64 Apaches, and other turbine-powered aircraft.

Key Sections of DA Form 2408-19

The form (November 1991 edition) includes specific blocks for comprehensive tracking:

  • Blocks 1-7: Part number, serial number, aircraft, nomenclature, NSN, CAGE number, and stage.
  • Block 8: Acceptance date.
  • Block 9: Wheel diametrical measurements (before/after grind, with blades).
  • Block 10: Abnormal temperature and/or overspeed data (engine time, wheel time, temperature, speed, remarks, time over limit).
  • Block 11: Installation data (engine model/SN, installed/removed dates and times, reason for removal, activity).
  • Block 12: Additional removal/replacement data.
  • Reverse Side: Turbine wheel blade data, significant historical entries, blade part numbers, positions, and remarks.

How to Properly Fill Out DA Form 2408-19?

Follow instructions in DA PAM 738-751 for accurate completion. Key guidelines include:

  1. Use black or blue ink; entries must be legible and permanent.
  2. Record all measurements, events, and transfers precisely.
  3. Update during installations, removals, inspections, or maintenance actions.
  4. Include supporting data like engine hours and activity identifiers.
  5. Retain the form with the component or forward it as required during transfers or overhauls.

Maintenance supervisors and technical inspectors typically handle entries. Always cross-reference with related forms like DA Form 2408-16 (Aircraft Component Historical Record) or engine-specific analysis records.

Pro Tip: Units often maintain these records in both physical and digital formats (where authorized) for easy access during inspections or deployments.

DA Form 2408-19 is part of a family of records:

  • DA Form 2408-16 — Aircraft Component Historical Record.
  • DA Form 2408-19-1 / 2408-19-2 — Turbine Engine Analysis Check Records (T53/T55 or T700 series).
  • DA Form 2408-13-1 — Aircraft Inspection and Maintenance Record.
  • DA Form 2408-20 — Oil Analysis Log.

These forms work together to provide a complete picture of engine and component health.

Best Practices for U.S. Army Aviation Units

  • Conduct regular audits of turbine wheel records during phased maintenance.
  • Train personnel on proper documentation to avoid discrepancies during quality assurance checks.
  • Use the form to support trend analysis for fleet-wide maintenance decisions.
  • Ensure forms travel with the component during transfers or depot-level repairs.

Proper use of DA Form 2408-19 helps prevent unexpected failures, extends component life, and supports overall aviation safety.
