A Lead Mechanic and a Mechanic report on their efforts to have Management personnel hold an A300 at the gate; due to a lack of documentation in the logbook for a temporary repair on the #2 engine reverser half.

Narrative

Found previous temporary repair; reapplied. During investigation of previous documentation; aircraft was allowed to leave gate. Repeated attempts to have aircraft return to gate failed. Aircraft departed without proper documentation. Notified management to have aircraft return to gate. Aircraft on the ground when management requested to have aircraft return and both times they failed. Supplemental information from ACN 823829: Assigned to aircraft by Lead Mechanic to reapply speed tape to existing repair on #2 engine reverser half. Lead Mechanic had informed me that he was going to take care of research and documentation of the logbook. Checked with Lead Mechanic about what he had found. He informed me that the aircraft left without any documentation in logbook; even though management was notified to hold aircraft for documentation in logbook. Management is having the logbook page corrected upon return. Management failed to have aircraft return to gate for completion of documentation of logbook.
