Narrative:
The king air A100's landing gear was being worked on by our mechanics. After the gear was tested successfully on the ground, I did a flight test. While in the pattern, I lowered the gear. However, the nose gear indicator did not show the nose gear to be locked down. I did an emergency go around and exited the pattern to work on the problem at a higher altitude. I manually pumped the gear down and re-entered the pattern. The landing was uneventful. The mechanics reviewed the problem and discovered that the chain that raised and lowered the nose gear had become loose. (I was told by the mechanic that this problem was not a part of the original problem.) the chain and actuators were readjusted and the problem appears to have been solved.
Original NASA ASRS Text
Title: A BEECH KING AIR 100 AT 1000 FT FOUND ON LNDG GEAR EXTENSION NO NOSE GEAR SAFE INDICATION. EXTENDED GEAR MANUALLY WITH UNEVENTFUL LNDG.
Narrative: THE KING AIR A100'S LNDG GEAR WAS BEING WORKED ON BY OUR MECHS. AFTER THE GEAR WAS TESTED SUCCESSFULLY ON THE GND, I DID A FLT TEST. WHILE IN THE PATTERN, I LOWERED THE GEAR. HOWEVER, THE NOSE GEAR INDICATOR DID NOT SHOW THE NOSE GEAR TO BE LOCKED DOWN. I DID AN EMER GAR AND EXITED THE PATTERN TO WORK ON THE PROB AT A HIGHER ALT. I MANUALLY PUMPED THE GEAR DOWN AND RE-ENTERED THE PATTERN. THE LNDG WAS UNEVENTFUL. THE MECHS REVIEWED THE PROB AND DISCOVERED THAT THE CHAIN THAT RAISED AND LOWERED THE NOSE GEAR HAD BECOME LOOSE. (I WAS TOLD BY THE MECH THAT THIS PROB WAS NOT A PART OF THE ORIGINAL PROB.) THE CHAIN AND ACTUATORS WERE READJUSTED AND THE PROB APPEARS TO HAVE BEEN SOLVED.
