Aviation Maintenance Data Specialist

0545 at the data control office pulling last night's flying hours and any after-hours maintenance actions. By 0630 you're reconciling NALCOMIS status against the aircraft logbook and flagging anything that doesn't match for the 0700 turnover brief. Morning is processing MAFs from the night check; afternoon is working the FMC/PMC inputs for the weekly readiness report. Last task every day: run the open-MAF report and make sure nothing aged past 24 hours without resolution.

Monday you're setting up the weekly readiness data package. Wednesday the QA auditor pulls your data — be ready to explain every administrative correction you made. Friday you brief the data package to the production control officer and get changes back before the weekend. Any weekend flying generates MAFs that'll be waiting Monday morning.

Learn to read the FMC trend data well enough to identify which system codes are driving availability drops before the Maintenance Officer asks. Start building your understanding of the T/M/S aircraft's major system WUC structure — it'll pay off when you need to explain why PMC is rising in a specific equipment area.

COMNAVAIRFORINST 4790.2 Series chapters on readiness reporting and the DRRS data submission requirements. The applicable T/M/S NATOPS Maintenance Manual for your aircraft type gives you the system breakdown that makes WUC codes meaningful rather than arbitrary.

FMC/PMC status must reconcile with the aircraft logbook daily — discrepancies between NALCOMIS and the paper record are a command inspection finding. At most squadrons this reconciliation happens at morning turnover and the Maintenance Chief signs off; if it doesn't add up, you're the one explaining it.

Closing a CAD (Cannibalization Action Document) as a routine MAF because you're not sure how to process it correctly will destroy your cannibalization rate metric and potentially violate NAMP reporting requirements. CANs have their own workflow and their own data fields — if you're unsure, ask before you close it wrong.

This is the tier where you decide whether to go deep on NALCOMIS and position yourself for a data chief role, or stay surface-level and end up a perpetual data entry Marine. The Marines who go deep start volunteering to run the DRRS submission and learning how the squadron data feeds into wing-level reporting.

At a fleet squadron you're in the day-to-day grind of flight operations data — high MAF volume, tight timelines. At an IMA the maintenance actions are more complex, the job sequences longer, and you're more likely to see CANN actions and high-dollar component tracking. The IMA billet teaches you the depth; the squadron teaches you the tempo.

An E-4 who produces a clean, discrepancy-free readiness data package for the Thursday brief without prompting — and who can answer follow-up questions about why specific WUC codes are trending — is doing the job the way it's supposed to be done. Excellence looks like the Maintenance Officer never having to say 'where did that number come from?'

Sergeant expects you to own the readiness brief data package end-to-end and to mentor junior 6046s on NALCOMIS — you can't just do the job anymore, you have to be able to teach it.
