splitpin Posted December 9, 2007 Report Share Posted December 9, 2007 In all my years flying I never had an emergency that I could have trained for, they always seemed to happen at the most inapropriate time and it was basically responding to a situation and survival. My biggest concern was knowing what the machine I was flying was capable of doing and each machine was different, even the same category and model. Back to my Navy days, we had recently overhauled HUP-3 Piaseki (year prior) in the hangar doing 300hr. inspection. One of the checks was to put the rigging pins in the heads to check that all controls were at the required settings. Upon lifting the pichhorn on the M/R head the unit came up and would not go back down to fit the rigging pin. Checked in the cockpit and found that the screwjack that contolled the pitchchange mechanism was off it's mount on the transmission. Without going into to much detail, the main rotor system is controlled on both heads by screwjacks mounted on the respective transmissions, the screwjacks go up and down controlled mainly by the collective (initial power setting). Inside the screwjacks is a locknut that prevents the screwjack from coming of the stud mounting on the transmission. The locknuts had never been installed at overhaul and nobody had ever pulled the collective to it's maximum IN THREE HUNDRED FLIGHT HOURS, TALK ABOUT THE GOLDEN HORSESHOE. I guess what I'm trying to say is, a person reacts to a situation in what he/her has been exposed to, if you have time. Don Don: You didn't mention the three chain sprockets on each screwjack. I remember checking the rigging on those screwjacks as well. What a maintenance nightmare!! Why don't you PM me when you get the time. Our paths have probably crossed as there were not a lot of guys that worked n the HUP-3. Quote Link to comment Share on other sites More sharing options...
