Narrative:

The aircraft, a seneca ii, underwent routine annual inspection, and during the inspection a problem was idented with the right main gear, and it was corrected. On the initial test flight, the gear up indicator did not indicate the gear going up correctly. The right main gear was adjusted and the problem was resolved. A subsequent test flight showed the gear to be operating properly on several lndgs. On aug/sat/01 at approximately XA30Z, I departed ZZZ in VMC on an IFR flight plan. The flight was uneventful, with minimal IFR conditions en route. The approach was in VMC, and there were no problems with the landing procedure. When the gear were put down, 3 green down indicators were seen. On landing, a normal touchdown was noted, then a progressive series of bounces occurred and the aircraft started to deviate to the right off the runway. I applied full power and executed a go around procedure. The climb rate was poor and the front gear did not go up, as seen in the mirror. The tower was able to report that all the gear were down, and I was able to land on the next attempt. I was able to taxi to the hangar, where on shutdown the right propeller was noted to be bent, indicating a propeller strike had occurred. An airport open house was scheduled for that wkend, and military were on the field. One of them came over to me and advised me he had seen the entire sequence. According to his description, the right main gear had not been extended on the first landing attempt. The nose and left main landing gear were extended in the down position.

Title: A PIPER PA34 ON LNDG WITH 3 GREEN POS INDICATING LIGHTS THE R LNDG GEAR WAS NOT FULLY EXTENDED. ACFT INCURRED DAMAGE.

Narrative: THE ACFT, A SENECA II, UNDERWENT ROUTINE ANNUAL INSPECTION, AND DURING THE INSPECTION A PROB WAS IDENTED WITH THE R MAIN GEAR, AND IT WAS CORRECTED. ON THE INITIAL TEST FLT, THE GEAR UP INDICATOR DID NOT INDICATE THE GEAR GOING UP CORRECTLY. THE R MAIN GEAR WAS ADJUSTED AND THE PROB WAS RESOLVED. A SUBSEQUENT TEST FLT SHOWED THE GEAR TO BE OPERATING PROPERLY ON SEVERAL LNDGS. ON AUG/SAT/01 AT APPROX XA30Z, I DEPARTED ZZZ IN VMC ON AN IFR FLT PLAN. THE FLT WAS UNEVENTFUL, WITH MINIMAL IFR CONDITIONS ENRTE. THE APCH WAS IN VMC, AND THERE WERE NO PROBS WITH THE LNDG PROC. WHEN THE GEAR WERE PUT DOWN, 3 GREEN DOWN INDICATORS WERE SEEN. ON LNDG, A NORMAL TOUCHDOWN WAS NOTED, THEN A PROGRESSIVE SERIES OF BOUNCES OCCURRED AND THE ACFT STARTED TO DEVIATE TO THE R OFF THE RWY. I APPLIED FULL PWR AND EXECUTED A GAR PROC. THE CLB RATE WAS POOR AND THE FRONT GEAR DID NOT GO UP, AS SEEN IN THE MIRROR. THE TWR WAS ABLE TO RPT THAT ALL THE GEAR WERE DOWN, AND I WAS ABLE TO LAND ON THE NEXT ATTEMPT. I WAS ABLE TO TAXI TO THE HANGAR, WHERE ON SHUTDOWN THE R PROP WAS NOTED TO BE BENT, INDICATING A PROP STRIKE HAD OCCURRED. AN ARPT OPEN HOUSE WAS SCHEDULED FOR THAT WKEND, AND MIL WERE ON THE FIELD. ONE OF THEM CAME OVER TO ME AND ADVISED ME HE HAD SEEN THE ENTIRE SEQUENCE. ACCORDING TO HIS DESCRIPTION, THE R MAIN GEAR HAD NOT BEEN EXTENDED ON THE FIRST LNDG ATTEMPT.
