AeroBuild Ledger
FOR VAN'S RV-7/8/10/14, SLING TSi & KITFOX BUILDERS & OWNERS

Don't Spend 40 Hours Writing Your POH and DAR Inspection Binder from Scratch. Generate Both in 15 Minutes.

Under the FAA's Task-Based Phase I rules (AC 90-89C), you cannot sign off Phase I flight testing without placing a custom Airplane Operating Handbook (POH / AOH) inside your cockpit—and you can't pass your DAR inspection without verified 3-scale Weight & Balance math, mandatory cockpit placards, and a signed Form 8130-6 program letter. AeroBuild Ledger builds your entire custom aircraft operating manual, test card deck, and annual maintenance logbook automatically.

1. CUSTOM 8-SECTION POH / AOH
Auto-Built Pilot's Operating Handbook

Replaces 25+ hours in Word. Generates all 8 standard GAMA POH sections (Limitations, Emergency & Normal Checklists, Performance, W&B, and Systems) customized for your engine and V-speeds.

2. DAR CERTIFICATION KIT
3-Scale W&B + Mandatory Placards

Calculates empty weight from your 3 hangar scales, checks full-to-empty fuel balance, and lists every mandatory cockpit/exterior placard your DAR inspector checks.

3. TASK-BASED PHASE I
10 Kneeboard Cards + GPS Calibrator

Step-by-step cockpit cards for every AC 90-89C test flight, plus a 3-heading GPS airspeed indicator calibrator that feeds your verified speeds straight into your POH.

4. ANNUALS & RESALE VALUE
Condition Checklist + SB Tracker

18-zone Part 43 Appendix D annual checklist plus a permanent Manufacturer Service Bulletin (SB) & ELT/Transponder currency log that protects your aircraft's resale value.

Why Homebuilders Buy AeroBuild Ledger Instead of Fighting Word & Excel

Every Experimental builder hits the "Paperwork Wall" right before inspection day. Here is what your $79 license generates for your specific tail number:

DELIVERABLE #1 Saves ~25 Hours

Custom 8-Section Pilot's Operating Handbook (POH / AOH)

On Van's AirForce and Sling forums, the #1 request is *"Does anyone have a clean POH template?"* Instead of editing a stranger's Word doc with the wrong engine or fuel system, our generator builds a complete 8-section POH matched to your exact airframe, engine (IO-360/390/540 or Rotax 915iS), V-speeds, emergency memory items, and normal checklists.

✓ Required by FAA AC 90-89C to sign off Phase I
DELIVERABLE #2 Saves ~7 Hours

DAR Inspection Package: 3-Scale W&B, Placard Sheet & Form 8130-6 Letter

Enter your Left, Right, and Tail/Nose wheel scale weights to compute your official Empty Weight & Balance report (including Forward, Aft, and Empty-Tank landing checks). Includes a model-specific **Mandatory DAR Placard & Instrument Marking Checklist** plus your ready-to-sign Form 8130-6 Program Letter.

✓ Eliminates inspection-day paperwork delays
DELIVERABLE #3 Saves ~6 Hours/Yr

10 Phase I Kneeboard Cards + Annual Condition & Service Bulletin Log

Prints 10 cockpit kneeboard test cards for Phase I (with a 3-way GPS airspeed calibrator), followed by an 18-zone Annual Condition Inspection checklist (14 CFR Part 43 App D), a **Manufacturer Service Bulletin (SB) Compliance Table**, and ELT/Transponder currency tracker you'll use every year.

✓ Protects aircraft safety & resale value

Visual Balance Safety Chart

Green Line = Your Flight

Both green dots (Takeoff and Empty-Tank Landing) must remain inside the blue box to stay within factory balance and weight limits.

Why Your DAR Checks Both Dots:

On most RV and Sling airframes, fuel sits ahead of the pilot. Burning fuel in flight shifts your balance rearward. Checking both dots guarantees you won't drift past the rear balance limit before landing.
