Narrative:
Flying on an instrument flight plan, cleared for ILS runway 23, in high traffic and VMC conditions, I failed to perform the ritualistic gear down checks, and therefore neglected to lower the landing gear. I believe this was, in part, due to the fact that I was not flying in a normal approach situation for either IMC or VMC. I was vectored out for an extended approach, due to the high traffic, and requested to keep a maximum rate of speed all the way to the runway. Although the audible gear up warning alarm was signaling, I did not hear it until after the incident when I removed my headset. A normal landing was implemented with gear up, resulting in minimal damage. Prevention: to prevent this recurrence, I suggest a dual method of warning signals -- an alarm tied to the intercom in the headset, and a warning light tied to the instrument panel for a visual alarm.

Title: PLT OF AC112-A VECTORED FOR EXTENDED APCH AND NEGLECTS TO CHK GEAR INDICATIONS. HE DID NOT HEAR THE AUDIBLE WARNING DUE TO HIS HEADSET.
Narrative: FLYING ON AN INST FLT PLAN, CLRED FOR ILS RWY 23, IN HIGH TFC AND VMC CONDITIONS, I FAILED TO PERFORM THE RITUALISTIC GEAR DOWN CHKS, AND THEREFORE NEGLECTED TO LOWER THE LNDG GEAR. I BELIEVE THIS WAS, IN PART, DUE TO THE FACT THAT I WAS NOT FLYING IN A NORMAL APCH SIT FOR EITHER IMC OR VMC. I WAS VECTORED OUT FOR AN EXTENDED APCH, DUE TO THE HIGH TFC, AND REQUESTED TO KEEP A MAX RATE OF SPD ALL THE WAY TO THE RWY. ALTHOUGH THE AUDIBLE GEAR UP WARNING ALARM WAS SIGNALING, I DID NOT HEAR IT UNTIL AFTER THE INCIDENT WHEN I REMOVED MY HEADSET. A NORMAL LNDG WAS IMPLEMENTED WITH GEAR UP, RESULTING IN MINIMAL DAMAGE. PREVENTION: TO PREVENT THIS RECURRENCE, I SUGGEST A DUAL METHOD OF WARNING SIGNALS -- AN ALARM TIED TO THE INTERCOM IN THE HEADSET, AND A WARNING LIGHT TIED TO THE INST PANEL FOR A VISUAL ALARM.
