Aircraft Oxygen System Service
Oxygen systems maximize comfort and safety in high altitudes. Keeping your cabin properly pressurized and having supplemental oxygen available is vital. By booking aircraft oxygen system services from a reputable business, you can keep your equipment operational and safe.
HRD Aero Systems offers professional aircraft oxygen system inspections, servicing and repairs. Partner with an affordable, high-quality aviation service to prevent unexpected oxygen loss.
Navigating FAA and DOT Compliance Requirements
Inspectors are expected to put safety first. If oxygen cylinders have passed their DOT-mandated test dates, an inspector will immediately ground your aircraft. Adhering to strict Federal Aviation Administration (FAA) and Department of Transportation (DOT) regulations can be complicated, but it’s necessary to remain safe and operational.
Having a compliant maintenance, repair and overhaul(MRO) partner simplifies the entire process.
Comprehensive Oxygen System MRO Services
Compliance reduces the risk of having a flight grounded for extended periods. Instead of spending time working with multiple partners to meet your needs, why not embrace the benefits of a one-stop solution? HRD Aero Systems streamlines your maintenance and compliance needs, keeping you safely in the air.

DOT-Compliant Hydrostatic Testing
Aviation oxygen cylinder hydrostatic testing to DOT compliance verifies the integrity of your cylinders under pressure. You’ll receive testing solutions across a range of cylinder types, including:
- DOT 3AA steel cylinders: These cylinders typically require hydrostatic testing every five years.
- DOT 3HT steel cylinders: These high-tensile steel cylinders must undergo hydrostatic testing every three years.
- DOT 3AL (6061T6 aluminum) cylinders: These are subject to hydrostatic testing every five years.
- Composite cylinders: Cylinders such as DOT-E 8162 Kevlar/Composite and DOT-E 10945 Carbon/Composite require hydrostatic testing every five years.
HRD’s process ensures compliance with 49 CFR § 180.209 and other relevant regulations. For customers, this means maintaining the highest safety standards for aviation oxygen equipment.
