Maintenance Controller reported not advising Contract Maintenance to perform several additional inspections after a jet bridge canopy struck the L1 Door. It was later determined that the L1 Door had sustained damage. The aircraft was removed from service for repair.

Narrative

Aircraft X flew from ZZZ to ZZZZ. Subsequent flight from ZZZZ to ZZZ; local time XA:12; jet bridge's canopy retracted and interfered the L1 door. Approximately 1 hour 30 minutes after the incident; Maintenance was notified after a Contract Maintenance accomplished the inspection and operational check of the L1 door in accordance with AMM XX-XX-XX; FORWARD ENTRY DOOR INSPECTION/CHECK. Per Contract Maintenance's statement; no door malfunctions noted and cockpit indications are good and no dent or fuselage damage noted. I was fixated on door operation and visual inspection only due to extensive maintenance delay without Maintenance knowing. As a result; I failed to advise the Contract Maintenance to perform further investigation; as per given AMM task 'GROUND HANDLING EQUIPMENT HITS AIRPLANE OR PART DEPARTS AIRPLANE' AMM task XX-XX-XY. Based on contractor's finding; I released the plane so it flew subsequent flight to ZZZ. However; once Aircraft X arrived to ZZZ; the abnormal door movement was noted by Gate Agent; and ZZZ Maintenance found damage in the upper hinge on L1 door. After 6 days; I noticed I forgot to ask contractor to perform 'GROUND HANDLING EQUIPMENT HITS AIRPLANE' AMM task.I felt pressure on time as customers are already boarded while I was communicating with the Contract Maintenance.Maintenance should be the first point of contact; as Maintenance related discrepancy or aircraft damage occurred; so the event information could be shared among the Maintenance Control department. Therefore; it possibly creates redundancy while minimizing delays.
