AF Form 4104: TH-1H Flight Evaluation Worksheet

AF Form 4104: TH-1H Flight Evaluation Worksheet – The AF Form 4104, officially titled TH-1H Flight Evaluation Worksheet, serves as the standardized document for assessing and documenting the performance of pilots and aircrew operating the TH-1H helicopter (a modernized variant of the iconic UH-1H Huey). The U.S. Air Force primarily uses this form for initial, requalification, and periodic flight evaluations, as well as Emergency Procedures Evaluations (EPEs).

Units conducting TH-1H training and operations rely on AF Form 4104 to ensure consistent evaluation of pilot proficiency, adherence to safety standards, and mission readiness in accordance with Air Force directives.

What Is the TH-1H Helicopter?

The TH-1H is the U.S. Air Force’s dedicated helicopter trainer. It features upgrades from the classic UH-1H Huey, including a more powerful engine (upgraded to approximately 1,600 shaft horsepower), a modernized cockpit, and enhanced structural components designed specifically for pilot training. The Air Force introduced the TH-1H to replace aging UH-1H airframes and modernize undergraduate helicopter pilot training, with the first production aircraft delivered in the mid-2000s. It supports Specialized Undergraduate Pilot Training (SUPT-H) at locations such as Fort Novosel (formerly Fort Rucker), Alabama.

This platform prepares pilots for a wide range of rotary-wing missions, emphasizing contact, instrument, and mission-specific maneuvers in a reliable, twin-engine configuration.

Purpose of AF Form 4104

Flight examiners use AF Form 4104 to record objective assessments during flight evaluations and EPEs. It aligns directly with the grading criteria and required evaluation areas outlined in AFMAN 11-2TH-1H Volume 2, TH-1H Helicopter Aircrew Evaluation Criteria (21 August 2023). This manual works in conjunction with the broader AFMAN 11-202 Volume 2, Aircrew Standardization/Evaluation Program.

Key purposes include:

  • Documenting pilot performance in ground and flight phases.
  • Supporting qualification (QUAL), instrument (INST), and mission (MSN) evaluations.
  • Ensuring compliance with standardization and safety protocols.
  • Providing a formal record for commander review, qualification tracking, and integration with AF Form 8, Certificate of Aircrew Qualification.

Evaluators must follow tiered compliance rules (T-2, T-3, etc.) when administering these evaluations.

How AF Form 4104 Fits into the Aircrew Standardization/Evaluation Program?

The Air Force Standardization and Evaluation (Stan/Eval) program validates aircrew readiness and the effectiveness of unit training. AF Form 4104 captures the flight portion of evaluations, while ground requisites (such as open-book exams, boldface procedures, and EPEs) complement it.

Evaluation types typically include:

  • Initial (INIT) and Requalification (RQ) evaluations — requiring comprehensive coverage of general and mission-specific areas.
  • Periodic (recurring) evaluations — focusing on a representative sample of maneuvers.
  • Mission (MSN) evaluations — scenario-based assessments tailored to unit missions, often incorporating day/night profiles and NVG operations where applicable.

For instructor pilots, additional sections evaluate teaching and supervisory skills. If certain items cannot be evaluated in flight, examiners may use alternate methods and document them appropriately on the associated AF Form 8.

Structure and Key Sections of AF Form 4104

While the official form is a multi-section worksheet (available as a fillable PDF), it generally organizes content into logical blocks for administrative data, grading of maneuvers/procedures, and remarks. Typical elements include:

  • Header/Administrative Information: Date, crewmember name/rank, evaluator details, type of evaluation (QUAL, INST, MSN, etc.), and flight data.
  • Section I – General Areas: Core flying skills, emergency procedures, systems knowledge, and basic maneuvers applicable to all evaluations.
  • Mission-Specific Areas (Section V or equivalent): TH-1H-specific tasks such as contact maneuvers, instrument procedures, autorotations, slope operations, confined area landings, and tactical elements.
  • Grading Criteria: Performance is graded according to standards in AFMAN 11-2TH-1H V2 and AFMAN 11-202 V2. Common descriptors include Qualified (Q), Unqualified (U), or detailed narrative feedback. Evaluators note strengths, deficiencies, and recommendations.
  • Emergency Procedures Evaluation (EPE): Often conducted on the ground or in a simulator/WST to allow in-depth systems questioning.
  • Additional Comments / Remarks: Space for detailed feedback, recommendations for training, or explanations of alternate evaluation methods.
  • Certification/Signatures: Evaluator and reviewed-by signatures, linking to the official qualification record.

The form emphasizes objective, standardized assessment to maintain high levels of proficiency and safety in TH-1H operations.
