01 / Occupational profile
Your 15T occupational profile
Flight-line and turbine engine noise
Common occupational factor
Ground-running turbine engines for maintenance checks, combined with routine flight-line activity, exposes helicopter repairers to hazardous noise levels comparable to or exceeding weapons noise in duration.
JP-8 fuel and hydraulic-fluid exposure
Common occupational factor
Routine fueling operations and hydraulic-system servicing bring regular skin and inhalation contact with JP-8 and hydraulic fluid, both recognized irritants in aviation-maintenance settings.
Overhead work and elevated-stand fall risk
Common occupational factor
Working overhead into the rotor head and transmission deck from stands and ladders is standard for the job and carries an inherent fall risk documented in Army aviation-maintenance safety literature.
Heavy-component handling
Common occupational factor
Removing and installing heavy parts such as transmissions, gearboxes, and rotor blades, often in coordination with a maintenance stand or crane, involves substantial lifting and awkward-posture demands.
Deployed dust and sand exposure
Common occupational factor
Maintenance in desert environments increases both the frequency of servicing tasks and the veteran's ambient exposure to fine particulate matter, relevant to the PACT Act framework depending on location and dates.
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.
Flight-line and hangar maintenance work involves inspecting, troubleshooting, and repairing rotor systems, transmissions, hydraulics, and airframe components on the UH-60. Ground-running engines for maintenance checks exposes crews to turbine noise well above hazardous thresholds, and fueling and hydraulic-system work brings routine skin and inhalation contact with JP-8 jet fuel and hydraulic fluid. Much of the physical work is done from stands, ladders, or the aircraft itself, reaching overhead into the rotor head or transmission deck, with a real fall risk from elevated work surfaces. Flight-line conditions add temperature extremes and, in deployed environments, dust and sand ingestion into moving parts that increases maintenance workload.
Duties that may vary by assignment
- Inspecting and repairing UH-60 rotor systems, transmissions, and hydraulic components
- Ground-running turbine engines for maintenance and diagnostic checks
- Working from maintenance stands, ladders, and the airframe itself, often overhead
- Routine contact with JP-8 jet fuel and hydraulic fluid during fueling and system servicing
- Working on an active flight line with rotating aircraft, noise, and rotor-wash conditions
- Deployed-environment maintenance in dusty or sandy conditions requiring more frequent servicing
- Physical demands of removing and installing heavy components such as transmissions and rotor blades

Building your occupational history
Records matter because they can connect a job title to an individual's actual work and circumstances.
Flight-line and turbine engine noise
Records that may corroborate it
- · Hearing-conservation audiograms (DD 2215/2216) and DOEHRS-HC enrollment records
- · Flight-line and hangar duty assignment records
- · Maintenance test-flight or ground-run logs
Limit: Flight-line assignment alone does not establish a current hearing-loss disability under 38 CFR § 3.385 or supply a nexus opinion.
JP-8 fuel and hydraulic-fluid exposure
Records that may corroborate it
- · Aircraft maintenance job cards and forms documenting fuel and hydraulic system work
- · Hazardous-material training and respiratory-protection records
- · Sick-call entries describing skin or respiratory irritation
Limit: Routine exposure to these substances does not by itself establish a skin or respiratory diagnosis; current findings and a supporting opinion are still required.
Overhead work and elevated-stand fall risk
Records that may corroborate it
- · Maintenance job cards documenting specific tasks performed
- · Line-of-duty determinations for any fall incidents
- · Physical profiles (DA Form 3349) for shoulder, back, or joint complaints
Limit: Overhead-work duty alone does not establish a shoulder or spine diagnosis or that a fall occurred; documented incidents or current findings are still needed.
Heavy-component handling
Records that may corroborate it
- · Aircraft maintenance records showing component-level work performed
- · Sick-call and orthopedic referral records
Limit: This duty pattern does not by itself establish a specific joint injury; current diagnosis and evidence of in-service onset are still required.
Deployed dust and sand exposure
Records that may corroborate it
- · Deployment orders and unit location records
- · Post-deployment health assessments (DD 2796/2900)
Limit: Deployment to a dusty environment alone does not establish presumptive status; the statutory location, time period, and a listed condition are all 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 sensorineural hearing loss
Why the occupation may matter: Ground-running turbine engines and flight-line duty are recognized hazardous-noise sources in aviation-maintenance occupations.
Records and clinical evidence: Current tinnitus report or audiometry meeting 38 CFR § 3.385, along with flight-line assignment and audiogram records.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Skin +
Contact dermatitis
Why the occupation may matter: Routine skin contact with JP-8 fuel and hydraulic fluid during servicing is a recognized irritant exposure.
Records and clinical evidence: Current dermatological diagnosis, treatment records, and documentation of fuel and hydraulic-system duty.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Respiratory +
Asthma, chronic bronchitis, and PACT Act presumptives
Why the occupation may matter: Inhalation of jet-fuel vapor and, during deployment, fine desert particulate matter are plausible respiratory stressors.
Records and clinical evidence: Current pulmonary testing, deployment documentation, and a diagnosis matching the presumptive list where applicable.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Shoulders +
Rotator cuff pathology
Why the occupation may matter: Sustained overhead reaching into the rotor head and transmission deck is a recognized mechanical stressor for the shoulder.
Records and clinical evidence: Current diagnosis with range-of-motion findings and job-card documentation of overhead maintenance tasks.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Lumbar/cervical spine +
Lumbar and cervical strain
Why the occupation may matter: Heavy-component handling and awkward postures while accessing internal aircraft systems place cumulative strain on the spine.
Records and clinical evidence: Current imaging, in-service sick-call records, and job-card documentation of component-level work.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Orthopedic — fall injury +
Fracture residuals, joint injury from a fall
Why the occupation may matter: Overhead work from stands and ladders around the aircraft carries an inherent fall risk documented in aviation-maintenance safety data.
Records and clinical evidence: A documented fall incident, contemporaneous treatment records, and current examination findings.
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 15T 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.
Hearing claim denied for lack of individualized noise documentation
Even though flight-line noise is well documented generally, examiners sometimes require specific evidence of ground-run frequency or hearing-conservation enrollment before accepting the exposure as established for that individual.
Skin condition attributed to a non-occupational cause
Dermatitis claims are sometimes denied where the examiner does not address the veteran's documented routine JP-8 and hydraulic-fluid contact and instead cites a general or unrelated cause.
Shoulder claim denied for lack of a single injury event
Cumulative strain from years of overhead maintenance work is sometimes discounted when an examiner looks only for a discrete in-service injury rather than a repetitive-use mechanism.
Respiratory claim denied outside the presumptive framework
Where deployment location and dates do not meet PACT Act criteria, a respiratory claim based on jet-fuel or particulate exposure requires its own nexus opinion, which examiners often find lacking without more specific exposure documentation.
Fall-related joint injury denied for lack of contemporaneous record
Falls from maintenance stands that were treated informally or not documented at the time are harder to connect to a current joint condition without lay statements and early post-service treatment records.
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.
15T questions
Does being a 15T automatically qualify me for a hearing loss claim?
No. It supports the noise-exposure element given routine ground-running of turbine engines, but a current hearing-loss disability meeting 38 CFR § 3.385 and a nexus opinion are still required.
I have skin irritation I never reported during service. Can I still claim it?
Yes, you can file. Your own account of onset and continuity is competent evidence, and job cards documenting fuel and hydraulic-system duty, along with current dermatological findings, help support the claim.
Does deployed maintenance work differ from garrison flight-line duty for these claims?
Deployment can add relevance to the PACT Act presumptive framework for respiratory conditions, depending on location and dates, but the noise, fuel, and physical-demand exposures are largely the same in garrison and deployed settings.
I fell from a maintenance stand and hurt my shoulder but never went to sick call. What should I gather?
Buddy statements describing the incident, any informal aid-station visit records, and your own detailed account of onset are useful, along with current imaging and examination findings.
Can cumulative overhead work support a shoulder claim without one specific injury?
Yes, in principle — repetitive overhead work is a recognized mechanical stressor — but the claim needs a current diagnosis and a medical opinion addressing that repetitive-use mechanism specifically.
What records show what I actually did as a 15T?
Aircraft maintenance job cards, ground-run and test-flight logs, hearing-conservation audiograms, hazardous-material training records, and NCOER narratives describing your maintenance assignment.
