FAA Drug Testing — Dulles Airport Employers (IAD)
Mobile FAA and DOT on-site drug and alcohol testing for ground handlers, cargo carriers, maintenance companies, and aviation contractors — collections at your IAD-area facility, not a clinic across town.
Washington Dulles International Airport (IAD) is a major international gateway for passenger and cargo aviation in the National Capital Region. Ground handlers, cargo integrators, aircraft maintenance and repair organizations, fueling contractors, catering companies, and airline-adjacent operations employ safety-sensitive workforces subject to FAA drug and alcohol testing under 14 CFR Part 120 and DOT procedures in 49 CFR Part 40.
OnSite Employer Testing coordinates mobile and on-site drug and alcohol testing for IAD-area employers in Sterling, Ashburn, Chantilly, Herndon, Reston, and the Dulles corridor. We come to your hangar, cargo facility, maintenance shop, or office — not the other way around. See our Arlington VA, Alexandria VA, and Manassas VA pages for broader Northern Virginia employer coverage. Review aviation and airline testing programs, how it works, and all locations.
Why On-Site Testing Makes Sense for Dulles Corridor Employers
Aviation operations do not run on clinic hours. Red-eye turns, overnight maintenance windows, early-morning cargo departures, and irregular crew rotations mean your safety-sensitive employees are often working when outpatient labs are closed or far from the airport corridor.
Mobile collections bring a DOT-certified collector to your authorized facility — your MRO shop, cargo warehouse, ground-handling station, or crew base — at the time your program requires. Random selections can be cleared in a batch without pulling half your ramp team off the operation. Post-accident and reasonable suspicion collections can be coordinated quickly when timing matters.
For airport-adjacent sites, access and badging rules vary. Share your facility address, gate or escort requirements, and site contact when you request coverage so we can confirm what is workable before collection day.
Industries We Serve Near Dulles (IAD)
Ground Handling and Ramp Operations
Ground handlers, baggage contractors, and ramp service companies employ large safety-sensitive workforces that move aircraft, load cargo, and support turn operations under tight schedules. These employers often maintain FAA Part 120 programs alongside employer handbook testing for non-covered roles.
We coordinate on-site collections at IAD-area ground handling facilities and off-airport staging locations in Sterling, Chantilly, and the surrounding corridor — aligned to shift changes and your DER's authorization.
Air Cargo and Freight Forwarders
Dulles is a major international cargo gateway. Freight forwarders, integrators, and warehouse operators run 24-hour sort and load operations with mixed DOT and Non-DOT workforces depending on role and vehicle use.
We coordinate pre-employment, random, post-accident, and reasonable suspicion testing for cargo employers along the Route 28 / Dulles Access Road corridor — including early-morning and overnight windows when clinic access is impractical.
Aircraft Maintenance, Repair, and Overhaul (MRO)
Part 145 repair stations and line-maintenance providers employ aviation maintenance technicians and other safety-sensitive personnel covered under FAA Part 120. Hangar and shop collections require private staging and correct chain-of-custody documentation under 49 CFR Part 40.
We coordinate mobile collections at MRO facilities and maintenance shops in the Dulles suburban market — without pulling technicians off an active aircraft for a clinic trip.
Aviation Contractors and Support Services
Catering, fueling, de-icing support, cleaning contractors, and other aviation-adjacent employers often maintain drug-free workplace programs for staff who work on or near airport operations. Some roles are FAA-covered; others follow Non-DOT handbook policies.
We coordinate both DOT and Non-DOT collections in a single visit when orders are clearly separated — reducing duplicate dispatch and donor confusion.
Airline Crew Bases and Flight Operations Support
Airlines and charter operators with Dulles-area crew bases must maintain FAA-compliant testing programs for pilots, flight attendants, dispatchers, and other covered safety-sensitive employees. Crew schedules rotate through IAD on irregular patterns that make clinic-based testing costly in lost duty time.
We serve aviation employers at and near IAD and coordinate with your site contact for access, staging, and donor flow. For broader aviation program context, see our aviation and airlines industry page.
FAA and DOT Drug and Alcohol Testing Requirements
Aviation employers at Dulles must maintain drug and alcohol testing programs under 14 CFR Part 120 (FAA) using collection and custody procedures in 49 CFR Part 40 (DOT). Official program guidance is published by the FAA Office of Aerospace Medicine — Drug & Alcohol Testing and the DOT Office of Drug & Alcohol Policy and Compliance (Part 40).
Safety-sensitive functions include flight crew, dispatch, maintenance personnel, ground security coordinators, and contract workers performing those roles. Employers must include pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing in a registered program — with BAT or other authorized modalities when alcohol testing is ordered.
- Pre-employment — before any covered employee performs safety-sensitive work
- Random — unannounced selections at FAA-published annual rates
- Post-accident — within federal windows after qualifying incidents
- Reasonable suspicion — based on documented supervisor observations
- Return-to-duty and follow-up — after violations, per SAP direction
- Alcohol testing — typically BAT under Part 40 when required
We coordinate DOT/FAA collections and mobile on-site visits; your DER and TPA remain responsible for program design, registration, and compliance decisions under applicable law.

Questions from employers in this region
Do you provide FAA drug testing for employers near Dulles Airport?
Yes. We coordinate mobile and on-site drug and alcohol testing for IAD-area employers with FAA Part 120 and DOT Part 40 programs — including ground handlers, cargo operators, MRO shops, and aviation contractors. Coverage depends on location, timing, and collector availability.
Can you collect at our facility in Sterling or Chantilly?
Often yes, when your site can provide private staging, restroom or observation access as required, and any airport or tenant badging is arranged in advance. Share your address and access rules when you request coverage.
What is the difference between FAA Part 120 and Non-DOT testing?
FAA Part 120 covers safety-sensitive aviation employees under federal rules administered through DOT Part 40 procedures. Non-DOT testing applies to employees covered only by your employer handbook policy. Orders, forms, and modalities must stay separated — we coordinate both when your program requires it.
Can you support random testing for our ground handling workforce?
Yes. Random batch collections at your facility are one of the most common requests from IAD-area aviation employers. Confirm pool size, selection timing, and site access when you submit your quote request.
Do you support breath alcohol testing for aviation employees?
Yes, when alcohol testing is part of your FAA/DOT order. BAT collections follow federal procedures under 49 CFR Part 40. State the modality when you schedule so the visit is staffed correctly.
Can you test at the airport itself, inside IAD?
Many collections happen at off-airport facilities, hangars, and cargo buildings in the Dulles corridor rather than airside. If you need collections at a tenant or airport-controlled location, share badging and escort requirements early — feasibility depends on access, timing, and program type.
