On the safety course they are very keen to emphasise that when belts are in their first hundred hours it is extremely important that you get blades turning in less than 5 seconds, otherwise the unpredictable slippage of sticky new belts could cause the belt to jump out of it's 'V' and become misaligned which has apparently been the cause of some incidents. Somebody I know felt an unexpected lump in there, the boot was removed to find that after maintenance a bit of locking wire (steel) was left just touching on the thin aluminium plate (held down by the nuts), one part was stationary and the other rotates, and over a short period of use the wire had stripped off a circle of the inner portion of the aluminium plate, leaving what looked like metallic orange peel coiled up under the boot.Ĭheck for smooth operation of the collective lever - if it's not smooth it could be indicative of overspeed (mis-shapen pitch change bearing I believe) Whilst there obviously check the fan scroll nut is aligned with the paint strip, if not, don't fly it (overspeed).Ī new one, from experience, is when checking the swash plate boot on the main rotor head you should feel a uniform circle of nut heads under the boot (approx 8-10), but you should not feel evidence of any other objects of un-uniformity. I was new to refuelling the aircraft and thought that perfect little flat on side/top of the fan scroll seemed a sensible place for it - not a good idea, ALWAYS put it on the seat so you notice upon embarkation if you haven't put it back in it's place.Ĭheck the bottom of the rotor mast fairing as previously mentioned for any rippling or dents indicating mast bumping/hard landing, also re:hard-landing check that you can just fit your fingers (small ish) between the bottom of the tail boom and the top of the fan scroll. During my Instructors course I was 10min into an exercise on airfield, and got a radio message from the tower "Helicopter XX, company message requesting you check your fuel cap" - they had found it on the pad :O. In retrospect, I wondered why the cap didn't have a safety chain so it couldn't go more than a few inches from the filler port.:ugh: I moved the stock one to the left side, put the tractor cap on the right side, and as I flew back to base, I periodically reached outside with my right hand and felt that cap to be sure it was staying tight.:E The second piece of luck of the day was that the old tractor on the field used for cutting the grass had the EXACT same fuel cap. This ship had paint marks to line up indicating the cap was completely on, and I would swear I had COMPLETELY tightened it. :mad: My heart skipped a few beats while thinking about the TR being in the path of the departing cap. After landing, one of the admiring throng asked "whatsat hole?" Hole? WHAT HOLE? It was the open fuel tank, left side. ![]() Not long after earning my rating (in the R22), I flew to a nearby airport to give my first passenger rides. Make certain the fuel caps are on completely and securely. ![]() This may seem waaaay basic, but it almost got me. ![]()
