Fixed-Wing Aircraft Airframe Mechanic, AV-8/TAV-8

0545 muster, overnight discrepancy brief from night check. Tool issue and first launch staging: pre-flight nozzle freedom-of-movement check, RCS duct visual, hot-structure panel security. Between sorties: work package execution on the grounded aircraft with an open phase discrepancy — you have the applicable MRC pulled, tools staged, and a plan before the CDI walks over to inspect. ADB documentation review with section NCOIC at midday. Afternoon sortie support and post-flight inspection. CDI prerequisite documentation update — if you have supervised actions that need to be logged, do it today, not next week. End-of-day tool accountability. Evening: Corporals Course study if that window is approaching.

VMA squadron weeks run against the flying schedule. High-tempo periods during work-up or detachment compress everything into continuous line presence. CDI prerequisite documentation needs to be updated weekly — supervised action log entries, proficiency records, work center chief endorsement tracking. The QA surveillance audit schedule for the airframe work center is published; know when your section is up and have documentation ready. Physical training is unit-scheduled but independently maintained. Corporals Course scheduling is through the career planner; get on the list early and track the date.

CDI inspection authority on the Harrier carries the same technical and legal responsibility it does on any aircraft in the fleet. A CDI signature on an ADB entry means you verified that the work was performed to the applicable NAVAIR standard — not that you trust the mechanic's write-up. Own NAMP Chapter 10 completely before you submit the CDI candidate package: what you are authorized to inspect as a CDI, what requires QAR escalation, what requires maintenance officer involvement, and what the documentation requirements are for a CDI-discovered quality escape. Harrier-specific CDI knowledge: nozzle rigging inspection criteria, composite hot-structure inspection standards, RCS bleed air duct inspection requirements, and the correct callout of any airworthiness-affecting discrepancy in the ADB. The LERX (Leading Edge Root Extension) and LID (Lift Improvement Device) inspection requirements are recurring scheduled inspections that a Cpl-level CDI will encounter regularly — know the applicable MRC task, the rejection criteria, and when to escalate to QAR. Water injection system functional check: know the procedure, the reject criteria for water flow rate and nozzle spray pattern, and how to document a discrepancy correctly.

COMNAVAIRFORINST 4790.2 (NAMP) Chapters 10 and 11 — CDI and QAR program authority; as a CDI candidate you are accountable to Chapter 10 in both directions (your own inspection standards and the quality of the packages you submit for CDI signature). NAVAIR 01-AV8BB-2-2 — AV-8B Airframe Maintenance Manual; at Cpl the expectation is that you can navigate to the applicable task without being shown — know the chapter structure well enough to find hydraulic, flight control, and nozzle system procedures quickly. NAVAIR 01-AV8BB-6 — scheduled maintenance MRC deck; CDIs are expected to know which MRCs apply to each phase inspection type. NAVMC 2795 — Marine Corps FitRep and Counseling Record Manual; understand the relative value system before your first Cpl FitRep is written about you, so you know what the section NCOIC is evaluating. MCO 1610.7 — Performance Evaluation System; the performance traits define the framework your CDI candidate record is assessed against.

Zero quality escapes on work packages where your name is in the mechanic block per QA audit cycle. CDI prerequisite package submitted within six months of Cpl pin-on — the package takes time, start it immediately. All ADB entries for work you perform are complete on first submission — no revisions requested by the inspecting CDI. Corporals Course complete before Sgt eligibility window opens. Physical fitness standard maintained at First Class across both PFT and CFT.

Completing a nozzle bearing inspection without physically verifying bearing preload per the applicable task — the visual check alone is not the standard, the preload measurement is. Misidentifying hot-structure composite delamination on the nozzle fairings as cosmetic surface damage — thermal cycling on the Harrier's exhaust nozzle composite panels creates subsurface delamination that is not visible without tap testing; a tap-test rejection on a fairing that was cleared as cosmetic is a quality escape with airworthiness implications. Closing an RCS bleed air duct discrepancy without verifying the adjacent structure for thermal damage — a leaking bleed air duct exposes adjacent composite and structural components to temperatures they were not designed for, and the repair that closes only the duct without inspecting the surrounding structure addresses the symptom, not the damage. Recording a system pressure check as satisfactory without documenting the actual measured values in the ADB — 'within limits' is not a complete corrective action entry; record the measured value, the limit, and the reference.

The reenlistment conversation is the most important decision point at the Cpl tier. With CDI LOA and clean records, the monitor will discuss formal cross-training to 6258 (F-35B) — this is the survival move for anyone who wants a full career in Marine Corps fixed-wing aviation maintenance. The VSTOL knowledge base from Harrier maintenance (nozzle systems, bleed air management, hot-structure handling) has real applicability to F-35B STOVL systems (lift fan, three-bearing swivel nozzle) and the F-35B program has recognized this in how it prioritizes former 6252 cross-trainees. Without CDI, the cross-training conversation is harder. The stay-or-go decision at six years: with CDI and Harrier qualification, the defense contractor market for depot-level Harrier support (NAVAIR Patuxent River contractors, L3 Aviation) is a real option while the platform is still in service.

VMA operational squadron at Yuma: highest operational tempo, most CDI inspection volume, desert thermal environment that accelerates hot-structure wear cycles. VMA at Cherry Point: East Coast fleet, proximity to NAVAIR depot support at Cherry Point NADEP for deeper maintenance coordination. MALS Cpl: component-level bench work on nozzle bearing assemblies, hydraulic actuators, and flight control surface components — the technical depth on specific Harrier components is greater at MALS than on the flight line and the documentation standards are more demanding. Training assignments: more deliberate maintenance environment, closer supervision, instructor exposure that builds teaching skills alongside technical skills. MEU deployment: the highest-visibility Cpl assignment — ship-based VSTOL operations with constrained logistics and no depot support nearby are the situations that reveal whether a Cpl's fundamentals are actually solid.

The exceptional Cpl 6252 runs work packages where the ADB entries require no revision before CDI signature, the corrective action language is specific and technically accurate, and the work center chief can read the entry and know exactly what was done and why. His CDI prerequisite package was submitted at the five-month mark of his Cpl tenure, not the eighth. He has introduced himself to the QA representative for the airframe work center by name and knows what the current discrepancy trend analysis shows for Harrier nozzle-system write-ups. He can explain the LERX inspection rejection criteria from memory — not because he memorized the table, but because he has performed the inspection enough times to understand what he is looking for.

Sgt is where CDI authority becomes the baseline, not the goal. The Sgt 6252 runs the section's day-to-day maintenance, manages junior Marines' OJT progression, writes FitReps, and carries CDI authority on the aircraft they are qualified to inspect — simultaneously, with no additional time in the day. The dual role of active maintainer and section NCO never fully separates at Sgt. The Harrier retirement reality becomes a more urgent career decision at Sgt: cross-train to F-35B or F/A-18, or begin planning the transition out of active service with the credentials you have built.
