16. Aircraft certified daily by such licensed ground engineers
    will be periodically reinspected by a person or persons duly

For this purpose the countersignature of the pilot may be accepted.

8. One copy of each certificate will be retained by the owner of the aircraft, and the duplicate copy must be carried in the aircraft.
