Step-by-step guides to every part of TachMinder — from your first aircraft to keeping a mechanic connected and your hours current.
What TachMinder is, how the shared workspace works, and your first steps.
One aircraft, one record, two roles: how owners and mechanics use the same source of truth — and what the app deliberately doesn't do.
Upload your registration, logbooks, and work orders and let the wizard build your aircraft record — or enter the basics by hand. Either way, your maintenance schedule is seeded automatically.
The sidebar, the one aircraft selector, the tab groups on your aircraft page, and where your current tach and Hobbs times come from.
What each tier costs, how the 14-day no-credit-card trial works, why AI and safety features are never gated, and how to manage billing in Settings.
A chat assistant grounded in your own records, AI pre-visit briefings for your mechanic, and document parsing — plus an honest account of what the AI is not.
Tach vs. Hobbs, maintenance clocks, and the ideas the app is built on.
Tach is engine-RPM-adjusted; Hobbs is clock time. Why the two differ, why every figure in the app is labeled, and which one drives your maintenance clocks.
Recurring items count down on engine hours and calendar months at once — whichever runs out first governs. How the clocks advance, what resets them, and what the app does when you edit an interval.
What Airworthiness Directives are, the four product categories they cover (including appliances), where TachMinder's AD catalog comes from, and what a proper compliance record contains.
Complied, complied (recurring), no record, adjudicated not applicable, and unverifiable — what each state means, and why TachMinder reports what your records show rather than rounding up.
Owners keep the aircraft airworthy and hold the records; a mechanic's signed logbook entry is the return-to-service approval. How federal law splits the roles, and how TachMinder mirrors it.
Keeping your hours, records, and maintenance schedule current.
Quick form, AI-prefilled single upload, or bulk upload with review — and why each flight's tach delta is what keeps hour-based maintenance countdowns accurate.
The Maintenance tab as a unified workbench — filtering maintenance items, ADs, and squawks, closing them with uploaded paperwork, and batch-recording A&P signoffs.
A co-authored view of your recurring service intervals — your mechanic proposes changes to discretionary intervals, you accept or decline, and your choice is canonical.
How photos and PDFs are classified, parsed, and reviewed before committing — plus the tail-number guard, duplicate protection, and staged AD review.
What the records-driven Legal to Fly evaluation covers, how to log a §91.171 VOR operational check, and why the IFR-equipped flag and airframe serial matter.
Tracking oil analysis metal levels and per-cylinder compression readings over time — and why TachMinder shows trends without pass/fail thresholds.
Logging installed appliances — autopilot, ELT, transponder, ADS-B — with part and serial details, so appliance AD matching can actually find what applies.
Inviting or approving a mechanic, what a linked provider can and can't see, reviewing their submissions, and keeping conversations anchored to the work.
What really happens when you change make or engine type, how the annual due date is computed, engine install tach, meter replacements, and former tail numbers.
Per-type email toggles, lead time, and cadence — plus which safety-critical alerts always send, and where the in-app notification stream lives.
Connecting to client aircraft and working the provider side of TachMinder.
Three ways a mechanic links to a client aircraft — tail-number request, owner invitation, or a managed placeholder profile — and what you can (and can't) see once connected.
What the provider Fleet view shows, the read-only co-steward view of a client aircraft — what you can and can't see — and how conversations with owners work.
How the Submit Work tab records maintenance completions, squawks, and logbook entries — with §43.9(a)(4) certificate capture, AI work-order pre-fill, and owner review of every submission.
The batch AD wizard for providers — enter AD numbers, review catalog matches, resolve applicability mismatches, and commit compliance records both you and the owner can see.
Free, A&P Pro, and Shop tiers compared — submissions, managed aircraft profiles, staff logins, and how provider settings and billing work.
TachMinder is an informational tool only. It is not a substitute for a certified A&P mechanic or IA. Only certificated mechanics and appropriately rated repair stations can approve return-to-service. Always verify Airworthiness Directive data with the FAA AD database (drs.faa.gov). TachMinder does not certify airworthiness.
