Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove work occurred, a signer is authorized, two people attended, a tag's location, airworthiness or a valid release to service.
It does not prove work occurred, a signer is authorized, two people attended, a tag's location, airworthiness or a valid release to service.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Is a task sign-off the aircraft release?
Not necessarily. The CAA guidance explicitly distinguishes a maintenance-step sign-off from release to service.

Context for this answerDoes every work entry require two people?
No universal two-person rule is established by 43.9. Required approval and credentials depend on the applicable work and rules.

Context for this answerDoes a tag tap prove an inspection happened?
No. Inspection entries require actual inspection information and authorized sign-off; a tap or file date supplies neither.

Context for this answerCan a receipt make a false log entry valid?
No. Current section 3.403 prohibits fraudulent or intentionally false statements in covered compliance records. The former section 43.12 is now reserved; a dated false record remains false.
