Narrative:
A 30 min VFR flight was being conducted to a local uncontrolled airport. While approaching the airport, communication was established with a preceding landing aircraft regarding the pilot controled runway lighting frequency change that had taken place 2 days prior and the runway being used and the landing sequence. The aircraft in front offered to hold clear on the ground while I completed my landing. When I reached touchdown ht, I sensed the landing gear was not taking the aircraft's weight. This was followed by uncharacteristic noise (blade strike) and a confirmation of 3 green lights not showing. A go around was immediately executed and landing made without further problem. Audible gear unsafe horn was not heard, and a higher throttle threshold setting would have assisted or, if there was additional link to the flap setting. Low prominence of placement of landing gear lights on instrument panel (1 light always obscured by gear handle) was a factor in recognition of problem. Although having called clear, the time of day and overcast sky took extra time in identing the other aircraft being clear of the runway.

Title: A PA31 NAVAJO ATX PLT EXPERIENCES MULTIPLE PROP STRIKES WHEN THE GEAR WAS NOT EXTENDED FOR LNDG AT W2K, AK. PLT MADE A SUCCESSFUL GAR FOR A FOLLOW UP LNDG.
Narrative: A 30 MIN VFR FLT WAS BEING CONDUCTED TO A LCL UNCTLED ARPT. WHILE APCHING THE ARPT, COM WAS ESTABLISHED WITH A PRECEDING LNDG ACFT REGARDING THE PLT CTLED RWY LIGHTING FREQ CHANGE THAT HAD TAKEN PLACE 2 DAYS PRIOR AND THE RWY BEING USED AND THE LNDG SEQUENCE. THE ACFT IN FRONT OFFERED TO HOLD CLR ON THE GND WHILE I COMPLETED MY LNDG. WHEN I REACHED TOUCHDOWN HT, I SENSED THE LNDG GEAR WAS NOT TAKING THE ACFT'S WT. THIS WAS FOLLOWED BY UNCHARACTERISTIC NOISE (BLADE STRIKE) AND A CONFIRMATION OF 3 GREEN LIGHTS NOT SHOWING. A GAR WAS IMMEDIATELY EXECUTED AND LNDG MADE WITHOUT FURTHER PROB. AUDIBLE GEAR UNSAFE HORN WAS NOT HEARD, AND A HIGHER THROTTLE THRESHOLD SETTING WOULD HAVE ASSISTED OR, IF THERE WAS ADDITIONAL LINK TO THE FLAP SETTING. LOW PROMINENCE OF PLACEMENT OF LNDG GEAR LIGHTS ON INST PANEL (1 LIGHT ALWAYS OBSCURED BY GEAR HANDLE) WAS A FACTOR IN RECOGNITION OF PROB. ALTHOUGH HAVING CALLED CLR, THE TIME OF DAY AND OVERCAST SKY TOOK EXTRA TIME IN IDENTING THE OTHER ACFT BEING CLR OF THE RWY.
