Helicopter Crew Chief, CH-53

Marine Corps MOS 6173 (Helicopter Crew Chief, CH-53) Marines are a rare breed in military aviation. They fill a dual role that does not exist in most other branches: they are both aircraft maintainers and active aircrew members. A 6173 is responsible for keeping the aircraft mission-ready on the ground and then flying on it as a crew member during operations.

Crew Chiefs serve primarily on the CH-53E Super Stallion (and the newer CH-53K King Stallion) or the UH-1Y Venom. Their ground duties include pre-flight and post-flight inspections, scheduled and unscheduled maintenance, corrosion control, and detailed maintenance documentation in OOMA (Optimized Organizational Maintenance Activity). Their aircrew duties include door gunner operations, helicopter rope suspension techniques (HRST), hoist operations, external load hookups, and in-flight systems monitoring.

Training starts at CNATT (Center for Naval Aviation Technical Training) in Pensacola, FL, where Marines learn the fundamentals of aviation maintenance. From there, they move to a fleet readiness squadron (FRS) for aircraft-specific training before joining an operational squadron. Common duty stations include MCAS New River (NC), MCAS Miramar (CA), MCAS Kaneohe Bay (HI), and overseas assignments in Okinawa, Japan.

What makes a 6173 uniquely valuable to civilian employers is the combination of hands-on mechanical expertise with operational aviation experience. These Marines do not just fix aircraft — they fly on them. That means they understand aircraft systems from both the maintenance bay and the cockpit perspective. Add in the safety discipline required for aircrew operations, leadership of maintenance teams, and meticulous documentation habits, and you have a skillset that translates across multiple civilian career paths.

Helicopter Crew Chiefs translate to civilian rotor-wing maintenance roles, FAA A&P licensing, and DoD depot positions consistently — Sikorsky, Lockheed, and DoD aviation programs all actively recruit 6173s. From the federal hiring side, the airframe and aircrew dual background is the package. — Brad Tachi, Navy Diver veteran & BMR founder

The civilian aviation maintenance industry actively recruits former military crew chiefs. Your combination of airframe maintenance experience and flight operations knowledge gives you a head start that most civilian technicians do not have. The key to unlocking civilian aviation careers is the FAA Airframe and Powerplant (A&P) certificate — and your military experience counts toward the requirements.

According to the Bureau of Labor Statistics (May 2024), the median annual wage for aircraft mechanics and service technicians is $78,680 (O*NET 49-3011.00). Employment stands at approximately 139,400 workers with average projected growth of 3-4% through 2034 and roughly 11,300 annual job openings. For avionics technicians (49-2091.00), the median is $81,390 with much faster than average growth (7%+).

Here are the primary private sector career paths for former 6173s:

Aircraft Mechanic / A&P Technician

This is the most direct path. With your military maintenance experience, you can apply to the FAA for your A&P certificate using FAA Form 8610-2 and your military training records. Many 6173s qualify for at least the Airframe rating based on documented maintenance hours. The Powerplant rating may require additional study or experience depending on how much engine work your specific squadron assigned. BLS median: $78,680/year.

Helicopter Maintenance Technician

Your platform-specific knowledge on the CH-53 or UH-1Y makes you especially attractive to helicopter operators. Companies running Sikorsky S-92s, S-76s, or Bell 412s value Marines who already understand rotary-wing systems, rotor track and balance, flight control rigging, and dynamic component maintenance. Helicopter-specific positions often pay above the general A&P median due to the specialized skillset.

Aviation Maintenance Inspector

If you held CDI (Collateral Duty Inspector) or QAR (Quality Assurance Representative) qualifications, you already performed inspection work. Civilian aviation inspectors — including FAA Designated Airworthiness Representatives — earn strong salaries. Transportation inspectors (53-6051.00) earn a BLS median of $85,750.

MRO (Maintenance, Repair & Overhaul) Technician

Large MRO facilities like those run by HAECO, ST Engineering, AAR Corp, and StandardAero employ hundreds of A&P mechanics for heavy maintenance checks on commercial and military aircraft. Your depot-level maintenance familiarity (if you supported I-level or worked with depot teams) is a direct match.

Helicopter EMS / Air Ambulance Operations

HEMS (Helicopter Emergency Medical Services) operators like Air Methods, PHI Health, and Med-Trans Corporation need experienced helicopter mechanics at bases across the country. These positions often involve single-mechanic bases where you maintain one or two aircraft independently — a good fit for crew chiefs who are used to owning their aircraft.

Oil & Gas / Offshore Helicopter Support

Companies like Bristow Group, PHI Inc., and Era Group operate large helicopter fleets supporting offshore oil platforms, primarily in the Gulf of Mexico. Heavy-lift helicopter experience on the CH-53 translates well to the S-92 and AW189 platforms used offshore. These positions tend to pay above average due to the remote work environment.

Defense Contractors

Sikorsky (Lockheed Martin), Bell Textron, and Boeing all hire former military crew chiefs as field service representatives, technical writers, and production technicians. Your platform knowledge — especially if you worked on the CH-53K King Stallion program — has direct value to the OEM. These roles often come with Secret clearance requirements, which you already hold. See how Army 15T Black Hawk Repairers make a similar transition.

NAVAIR, Fleet Readiness Centers, and DLA Aviation employ hundreds of aircraft mechanics and maintenance specialists across WG-8852 and related series. Former 6173s with CH-53 or UH-1Y experience bring maintenance documentation, safety compliance, and hands-on troubleshooting that federal aviation employers need. Your military experience maps to many GS and WG job series beyond just aircraft mechanic positions.

Major federal employers for former helicopter crew chiefs include NAVAIR (Naval Air Systems Command), MCSC (Marine Corps Systems Command), Army AMCOM (Aviation and Missile Command), DLA (Defense Logistics Agency), FAA, and NASA.

If you are staying in aviation maintenance, your terminology is the industry standard. A&P shops, MROs, and helicopter operators know exactly what a pre-flight inspection and a MAF mean. This section is for careers outside aviation — where the hiring manager has no idea what OOMA is or why a "phase inspection" matters.

The translations below reframe your 6173 experience into language that works for non-aviation industries: manufacturing, construction, project management, operations, and safety. These are not just word swaps — they show how to present your experience so a hiring manager in a completely different field understands the value.
