01 / Occupational profile
Your 15R occupational profile
Turbine engine and rotor noise
Common occupational factor
Flight-line and hangar work places repairers near running turbine engines and rotor systems during ground runs, maintenance test flights, and routine servicing.
Solvents, hydraulic fluid, and fuel contact
Common occupational factor
Servicing and lubricating aircraft subsystems involves routine skin and inhalation contact with solvents, hydraulic fluid, and fuel.
Awkward postures and heavy component handling
Common occupational factor
Removing and installing engines, rotors, and transmissions, and working in confined aircraft spaces, load the back, shoulders, and knees.
Maintenance test-flight vibration
Common occupational factor
Repairers who perform maintenance operational checks and test flights are exposed to helicopter vibration and dynamic flight conditions.
02 / Your service
What did you actually do?
Your MOS is the starting point. Your actual assignment, era, equipment, location, and duties determine which parts of the occupational history are relevant. Use the Evidence Builder below to select your actual duties and see records that may corroborate them.
15Rs remove and install engines, rotors, gearboxes, transmissions, and flight-control components; service and lubricate aircraft systems; and perform scheduled and special inspections. Diagnosing and troubleshooting subsystem malfunctions uses hydraulic and electronic test equipment, and some 15Rs perform maintenance test-flight duties as required. Work occurs on the flight line and in hangar bays around running engines and rotor wash, and involves solvents, hydraulic fluid, and lubricants during servicing. Deployed units maintain aircraft in field conditions with limited shelter.
The AH-64 fleet progressed from the A model to the D (Longbow) and E (Guardian) variants across the 15R's history; engine, rotor, and avionics systems differ enough between models that the specific aircraft variant can matter for documenting equipment and tasks.
Duties that may vary by assignment
- Removing and installing engines, rotors, gearboxes, and transmissions
- Servicing and lubricating aircraft and subsystems
- Performing scheduled and special inspections
- Diagnosing and troubleshooting subsystem malfunctions with test equipment
- Performing maintenance test-flight duties, where qualified
- Working on the flight line around running engines and rotor wash
- Handling solvents, hydraulic fluid, and lubricants during servicing
- Field and deployed aircraft maintenance

Building your occupational history
Records matter because they can connect a job title to an individual's actual work and circumstances.
Turbine engine and rotor noise
Records that may corroborate it
- · Hearing-conservation audiograms (DD 2215/2216) and DOEHRS-HC records
- · Flight-line duty and maintenance test-flight records
- · Evaluations describing flight-line or hangar duties
Limit: Documented noise supports the in-service event only. A current hearing disability under 38 CFR § 3.385 or a tinnitus complaint, and a medical link, are still required.
Solvents, hydraulic fluid, and fuel contact
Records that may corroborate it
- · Hazmat or maintenance training certificates listing products handled
- · Unit safety or occupational health records, if enrolled
- · Evaluations describing maintenance duties and tasks
Limit: The MOS does not establish contact with any specific chemical or the level of exposure; facility, era, tasks, a current diagnosis, and a medical opinion all still matter.
Awkward postures and heavy component handling
Records that may corroborate it
- · Sick call and physical therapy entries during the assignment
- · Line-of-duty or incident reports for a documented injury
- · Evaluations describing maintenance duties
Limit: Typical maintenance demands do not by themselves establish that a specific joint was injured in service.
Maintenance test-flight vibration
Records that may corroborate it
- · Flight records or logs showing maintenance test-flight duty
- · Aviator or crew-member badge or orders, where applicable
- · Evaluations describing test-flight duties
Limit: Test-flight duty alone does not establish a current spine or vestibular condition; a current diagnosis and medical opinion are required.
04 / Evidence standard
What your MOS can — and cannot — establish
May help document
Work performed, circumstances of service, consistency of an alleged exposure, and the nature or duration of duties where supported by individual records.
Does not automatically establish
A diagnosis, medical causation, severity, percentage, presumption, or entitlement to service connection.
05 / Medical evidence
Conditions that may be relevant to the occupational history
This is not a list of conditions to claim. A veteran's actual diagnosis and individual service record determine relevance; occupational evidence is not medical causation.
Hearing +
Tinnitus and hearing loss
Why the occupation may matter: Turbine engine and rotor noise are sustained on the flight line and in the hangar.
Records and clinical evidence: Audiometry meeting 38 CFR § 3.385, service audiograms, and a medical opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Skin / respiratory +
Skin or respiratory conditions from solvent and fuel contact
Why the occupation may matter: Servicing aircraft systems involves routine contact with solvents, hydraulic fluid, and fuel.
Records and clinical evidence: Current diagnosis, duty records, and a medical opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Spine / joints +
Back and shoulder conditions
Why the occupation may matter: Removing and installing heavy aircraft components in confined spaces loads the back and shoulders.
Records and clinical evidence: Current diagnosis, duty records, and a medical opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
06 / Exposure record
ILER and toxic exposure
For applicable exposure-related claims, VA may review the Individual Longitudinal Exposure Record (ILER) and a toxic exposure risk activity (TERA) memorandum along with deployment and occupational records. An ILER entry does not automatically establish exposure or service connection.
07 / After a decision
Why a 15R claim may still be denied
An exposure finding is not the same as a grant. These are examples from the researched guide, not predictions about a particular case.
VA may accept
A duty or event consistent with the service record
But may deny
A diagnosis, medical relationship, or rating element
Record to examine
Decision findings, service and private treatment records, examination rationale, and medical opinions.
Chemical exposure described too generally
Statements like "I worked with solvents" without naming products or tasks are hard for VA to evaluate; maintenance and hazmat training records may add specifics.
No in-service complaint on file for joint pain
Maintainers often worked through strains from awkward postures; evaluations and buddy statements may help document the duty demands.
Hearing link rejected on separation audiogram
A normal separation audiogram alone does not decide a hearing claim, but examiners often rely on it without addressing the full flight-line noise history.
Oakridge Claims / Appeals Focused
Already have a VA decision?
The important question is what VA accepted, what it rejected, and why. A decision review considers the decision, examinations, and the complete record — including private and VA records that may need development. Oakridge is appeals-focused — core work is post-decision, but initial and new claims are accepted on a case-by-case basis (no fee for pre-decision work).
Fees for eligible post-decision representation are governed by a written agreement. See fee details. No outcome is guaranteed.
15R questions
Does serving as a 15R prove I was exposed to a specific chemical?
No. It shows the occupation involved aircraft maintenance; which solvents, fluids, or fuels you handled, and how often, depended on your unit, facility, and era. Maintenance and hazmat training records may help document the specifics.
What records show which AH-64 variant I worked on?
Assignment orders and evaluations describing your unit and aircraft are the usual starting points.
Is being near running aircraft engines itself a disability?
No. Exposure is an event, not a disability. A current diagnosed condition and a medical link to service are still required.
