Fixed-Wing Jet Aircraft Mechanic

You are the wrench. Not a metaphor — you are the hands on the jet, doing the work that keeps aircraft flying. Everything you touch has a procedure, every procedure has a signature block, and that signature block has your name on it.

Perform scheduled and unscheduled maintenance on fixed-wing jet aircraft under direct supervision. You execute maintenance action forms (MAFs), do FOD walks before and after every flight op, handle tool control accountability, assist with engine runs, and learn the aircraft systems from the bottom up. Expect hydraulics, flight controls, landing gear rigging, and a lot of corrosion control on your plate early. You are learning the NAMP (COMNAVAIRFORINST 4790.2) whether you realize it or not — every procedure you follow is in it.

• 01MAF documentation, tool control accountability, FOD prevention, hydraulic servicing, basic airframe inspections, hazmat handling procedures, phase maintenance assist

• —COMNAVAIRFORINST 4790.2 (NAMP), applicable MIM/MRC cards for your platform (F/A-18, AV-8B, F-35B, or T-45), MCO 4030.37 series for hazmat

• —Zero FOD incidents on your watch. Every tool signed out is signed back in. Every MAF you touch is legible, accurate, and closed correctly. No pencil-whipping — ever. Your CDI or QA can pull any job you signed and it should hold up.

• —Rushing a pre-op inspection because the flight schedule is hot. Signing a MAF you did not actually do. Returning a tool to the wrong shadow and calling it close enough. Skipping the torque check because the bolt "felt tight." Each of these has killed people.

You show up early, do your FOD walk without being told, and you ask questions before you touch something you have never seen. Your toolbox count is never wrong. When a CDI reviews your work, they find it done correctly the first time. You are not the fastest LCpl in the shop — you are the most accurate one, and everyone notices.

You have enough hours on the jet to know what right looks like, and enough mistakes behind you to know how fast wrong happens. Now you are starting to lead tasks and sign off on your own work — which means your name is on the line, not just in the block.

Execute complex maintenance tasks with limited supervision. You are working toward your CDI designation or have recently received it — which means you can now inspect and accept work from junior Marines. You run maintenance tasks from open to close, manage the MAF package, and start pulling junior Marines through procedures rather than just doing the work yourself. On F/A-18s or F-35Bs, you are getting into hydraulic system troubleshooting, flight control rig checks, and engine removal/installation assists. You are also the one answering to the SSgt when a junior Marine does something dumb.

• 01CDI qualification (or in-progress), MAF package management, hydraulic troubleshooting, flight control rigging, engine R&R assist, task lead for 2-3 person maintenance actions, junior Marine supervision

• —COMNAVAIRFORINST 4790.2 Chapters 6 and 7 (CDI/QA program), platform-specific MIMs, NATOPS for your airframe, applicable naval messages for ALS/safety directives

• —Your CDI stamp means you personally verified the work is correct. If you stamp it and it is wrong, that is on you — not the junior Marine who did the work. Every task you lead gets documented correctly and closed on time.

• —Rubber-stamping work as a CDI without actually inspecting it. Taking shortcuts on rigging checks because the turn time is tight. Letting a junior Marine walk away from a job without correcting their documentation because you do not want the confrontation.

You run your task like a professional and your MAF packages close clean. When you stamp something as CDI, you staked your reputation on it and you know it. Junior Marines ask you questions because you give them real answers, not the "go figure it out" brush-off. Your SSgt does not have to chase you for status updates.

You are the technical backbone of the workcenter. You are not just doing maintenance anymore — you are ensuring the maintenance is right, the Marines doing it are learning, and the documentation holds up to a QA audit. The jet does not care about your feelings and neither does the NAMP.

Lead maintenance teams on complex, multi-man jobs. You are a CDI (if not already, this is the deployment where it happens or your career stalls). You are running engine runs, supervising hydraulic and flight control systems work, and managing the MAF packages for your section. At MALS or the squadron, you are the person the LTs come to for straight answers on maintenance status. You also own your Marines' 6105s, counseling chits, and training records. If a junior Marine makes a maintenance error, the investigation will involve you.

• 01CDI qualification (mandatory), engine run qualification, QA audit preparation, maintenance team leadership, HAZMAT coordinator assist, troubleshooting hydraulic/flight control/landing gear anomalies, personnel administration for junior Marines

• —COMNAVAIRFORINST 4790.2 full manual, NATOPS flight manual for your platform, applicable MIMs, T/M/S maintenance manuals, ALS/safety message compliance tracking

• —Your work center runs on time, your MAF packages are clean, and your Marines know the procedures before they touch the jet. When QA walks through, nothing surprises you. Your CDI stamp is your professional signature — treat it accordingly.

• —Not keeping current on safety of flight messages and naval messages that modify your procedures. Letting an unqualified Marine perform a task because you are short on bodies. Failing to document a discrepancy because fixing it takes longer than the flight schedule allows.

Your section's maintenance metrics are solid, your Marines are progressing through their qual cards, and your MAF documentation is the example the SSgt holds up in training. When something breaks on the flight line, you are the Sgt they radio because you know the aircraft and you know how to get the answer fast without guessing.

You run the workcenter. Not the building — the people, the schedule, the readiness numbers, and the culture. How your Marines work when you are not in the room is the truest measure of how well you are doing your job.

Manage daily workcenter operations including maintenance scheduling, resource allocation, and quality oversight. You are likely a QA representative or working closely with the QA division to ensure your workcenter's compliance posture is solid. You own your Marines' training pipelines — CDI designations, qual card completions, and NEC/MOS upgrades all run through you. You are the bridge between the GySgt/WO's operational vision and the Cpls and Sgts executing it on the deck. On deployment, you are the senior wrench in the shop making the calls when the officer is unavailable.

• 01Workcenter management, QA program participation, maintenance scheduling and prioritization, resource/parts coordination with MALS, personnel development and mentorship, mishap investigation assist, HAZMAT program management

• —COMNAVAIRFORINST 4790.2 (QA and CDI sections), MCO P4790.2 series, applicable naval aviation safety messages, MCO 3710.2 series for aviation safety

• —Your workcenter has zero QA major findings that were preventable. Your Marines are tracking on their qual cards and CDI designations. When the CO asks about aircraft readiness, the answer that comes back through the chain started with the numbers you gave the GySgt.

• —Micromanaging Sgts who are capable of running their own tasks — it erodes their confidence and your time. Letting administrative work pile up until it becomes a fire drill. Covering for a Marine who made a maintenance error rather than documenting and correcting it properly.

Your workcenter produces consistent, reliable maintenance without daily intervention from you. Your Sgts run their sections and your LCpls are becoming Cpls who actually know the jet. When the GySgt needs a status, you have it. When QA does a sweep, your records are clean because you built that habit into the daily routine — not because you stayed up the night before fixing paperwork.

You are the institutional memory of the squadron's maintenance department. You have forgotten more about this aircraft than most of your Marines have learned. Your job now is to make sure that knowledge does not stay locked in your head — it has to live in your people.

Serve as the senior enlisted technical authority for your maintenance department or MALS workcenter. You interface directly with WOs, LTs, and the Maintenance Officer on readiness, safety posture, and resource issues. You manage the division's training program, ensure CDI and QA qualification pipelines are healthy, and personally advise on complex troubleshooting cases where the MIMs are silent and experience is the only tool. You represent the division at maintenance production meetings, track aircraft readiness against commitments, and own the culture that makes the difference between a shop that performs and one that pencil-whips.

• 01Division-level maintenance management, technical authority for complex troubleshooting, QA program oversight, officer/SNCO interface on readiness decisions, training program management, safety and mishap prevention culture, HAZMAT program ownership

• —COMNAVAIRFORINST 4790.2 (complete), MCO P4790.2C, applicable OPNAV instructions, NATOPS, MARFORs/FMF aviation directives, applicable safety of flight messages

• —The maintenance department runs correctly when you are on leave. Your SSgts lead their workcenters without constant supervision. Your aircraft readiness rates reflect actual capability, not optimistic reporting. Every safety of flight message is tracked and complied with on time.

• —Becoming the person who solves every hard problem yourself instead of developing SSgts who can solve them. Letting a readiness metric get reported favorably when the real answer is "we have a problem." Tolerating a workcenter culture where pencil-whipping is quietly normalized.

The maintenance officer trusts your numbers because you have never given them a reason not to. Your SSgts are developing into GySgts. When a complex troubleshooting issue stumps the shop, you walk through it methodically, cite the relevant manual section, and either solve it or get the right WO or tech rep on the phone — and you know which one the situation calls for. The junior Marines know your name and your standards before they ever meet you.

You are not a mechanic anymore. You are a policy, a standard, and a culture. The Marines working on jets across your command will make decisions based on what they believe you would approve of. Make sure that belief is built on the right foundation.

At MSgt/MGySgt, you are the senior technical advisor and program manager for aviation maintenance at the group, wing, or MALS level. You own the big picture: readiness trends across squadrons, systemic training deficiencies, QA program health, HAZMAT compliance posture, and the pipeline of qualified CDIs and QA reps throughout the command. You advise the CO on maintenance risk in plain language and you are the last technical check before consequential decisions are made. At 1stSgt/SgtMaj, you own the human side — welfare, discipline, administration, and the moral climate of the command. Both tracks require that you communicate with officers as a peer on the subject matter that matters most.

• 01Command-level readiness management, QA and CDI program health across multiple workcenters, systemic troubleshooting trend analysis, HAZMAT and environmental compliance oversight, senior enlisted advisory to CO/XO, personnel development and succession planning, mishap prevention program leadership

• —COMNAVAIRFORINST 4790.2, MCO P4790.2 series, applicable MARFOR and TECOM directives, naval aviation safety program instructions, HQMC aviation maintenance policy messages

• —The command's readiness numbers are real. The QA program catches problems before aircraft do. Every CDI designation in the command was earned, not given. Marines know they can bring you a problem without getting smoked for finding it.

• —Losing touch with what the deckplate actually looks like because your days are full of meetings and PowerPoints. Letting a GySgt manage up to you rather than giving you the real picture. Confusing activity with effectiveness in the maintenance program.

You walk the flight line and the deckplate Marines read your body language as a signal of command climate. When you say something is the standard, it becomes the standard — because your career demonstrates that you actually held it. The officers you advise make better decisions because you give them accurate information in time to act on it. When you retire or leave, the program runs correctly without you — because you built it to outlast you, not to need you.
