A shop mechanic reports an A320 engine reverser was received in the component shop for overhaul due to internal delamination damage. A written engineering order to approve repair of the excessive delaminated area was not issued prior to an off-shift mechanic and inspector signing for the serviceability of the reverser.

Narrative:
A320 reverser sleeve was received in the shop for overhaul due to internal damage. A pre-inspection was done and a write-up documented the internal damage. Repair procedures [for excessive delaminations] are not covered in shop document or structural repair manual (srm); so I requested an engineering order (eo) calling out specific repair procedures. Engineering came down to the shop and entered the following statement on the jobcard; engineering recommends repair per maintenance manual (MM) 6-0-2. I emailed engineering and stated that a written engineering order was also needed because of the limitations stated in paragraph 5 of MM 6-0-2. While waiting for engineering to provide the required engineering document; the off-shift signed- off the repair and had inspection buyback. This unit now has been repaired without fully complying with the intent of MM 6-0-2 or the shop document and is soon to be released to service.
