Three parts. One logbook.

Everything CASA requires for your Part 66 licence in a single digital workspace.

PART 1

Knowledge

Track all 17 CASA exam modules. Record your score, exam date, and upload your pass certificate. See at a glance which modules are complete, pending, or need a re-sit.

Modules: Mathematics, Physics, Electrics, Digital Techniques, Human Factors, CASR & more

PART 2

Practical Training

All 348 CASA practical tasks in a searchable, ATA-filtered checklist. Add notes and evidence, then request supervisor countersignature in-app — secured by TOTP or biometric verification.

Categories: A • B1.1 • B1.2 • B1.3 • B1.4 • B2

PART 3

Operating Experience

ATA-coded task entries automatically accumulate toward your 2,000 hr target. Table 1 and Table 2 summaries auto-generate — with base vs line maintenance breakdown — ready for CASA submission.

Why digital over paper?

Paper logbooks work until they don't.

Paper Logbook

  • Lost, damaged, or soaked in hydraulic fluid

  • Supervisor not present — task sign-off delayed

  • No search — flick through 300 pages

  • Manual hour tallying with spreadsheets

  • Scan everything to email CASA

  • One copy — no backup if it burns

eLog66

  • Cloud-backed, offline-capable on every device

  • Push notification → supervisor signs remotely

  • Instant search across all 348 tasks

  • Hours auto-calculated per ATA chapter

  • One tap → CASA-ready Appendix C/D PDF

  • Fully encrypted with audit trail
