Narrative:

I was lead on [a B747 aircraft]. I assigned [two coworkers] to work the #1 engine. They reported that the aft mount inboard tangential link was loose with radial and axial play. We contacted inspection department and [an] inspector verified link was loose. We proceeded to make a log item to document discrepancy. We informed supervisor; and showed him the corresponding maintenance manual limitations; and that the engine mount components needed to be 'tightly attached and in good condition'. After some discussions that the item needed to be addressed; he instructed us to continue with the 'a' check as normal; and that he would follow up with this write-up (with dayshift).the next day; we found out that [the] supervisor had 'cancelled' the write-up and had voided any action with 'no discrepancies found' and had released the aircraft from the 'a' check visit. The aircraft flew as scheduled without this item being properly addressed (or fixed). At this moment the aircraft continues to fly without any maintenance action regarding this discrepancy; and we feel this item should at least be evaluated by engineering or maintenance control.(please note: we suspect that the tangential link was loose due to the spherical bearing wear; and in order to correctly measure its wear; or replace the link; the entire engine needed to be dropped; and the aircraft would not make its schedule flight time.)procedures should be properly followed by mechanics as well as management personnel. In the event there are questions as to how to proceed; engineering and or maintenance control should be consulted before voiding and discrepancies written up.
