Narrative:

Aircraft arrived at gate with pilot report of inadvertent gear down overspeed of 280 knots at 11;000ft. After consulting with maintenance control representative; a vmo/mmo inspection was complied with due to aircraft maintenance manual (amm) defines an overspeed as speed in excess of vmo +20kts. Maintenance control technical checked for an overspeed condition using ACARS playback and found aircraft had no overspeed condition on flight leg reported. As crew report had only a 10 knots overspeed maintenance control advised no other action was required. When aircraft arrived at base; aircraft was re-inspected in accordance with (in accordance with) aircraft maintenance manual (amm) for a landing gear down overspeed inspection; no damage was found on re-inspection. Conflicting amm references as to what is an overspeed condition and amm does not reference aircraft configuration at time of overspeed.

As crew report had only a 10 knots overspeed Maintenance Control advised no other action was required. When aircraft arrived at base; aircraft was re-inspected In Accordance With (IAW) Aircraft Maintenance Manual (AMM) for a landing gear down overspeed inspection; no damage was found on re-inspection. Conflicting AMM references as to what is an overspeed condition and AMM does not reference aircraft configuration at time of overspeed.
