    Actually, that idea of spraying urine around rabbit warrens is not unusual. As long as the urine comes from a meat eater, it will give rabbits cause for concern. If you use herbivore's urine, you'll only attract them. There's many an old granny who kept the rabbits off her veggie patch by emptying her guzunter around its borders every morning. If you want a good supply of deterrent urine, throw a barbie and ask your mates to piss in a bucket.

    You'd think that the crew might have twigged to the error when the compass was reading something like 300 and Dusseldorf is roughly 050 from London.

     

    I hope his grandfather wasn't a Lancaster pilot. Bombing Edinburgh with an English plane could have really lead to Anglo-Scottish separation.

    Ian,

     

    You might do better to get yourself out to a truck stop at Camberwell, or other place on the Hume and hitch a ride with an over-nighter. On the way home, go to Uncle Louie's at the Cross Roads, near Liverpool and get a ride from there.

    I find the intellectual exercise of using map, compass, chronometer and whizz wheel most enjoyable. However, it is only enjoyable while sitting at a desk doing the pre-flight planning. Digital technology adds to overall flying safety. It allows the pilot to carry out the primary role of a pilot - to fly the plane. Remember the first rule of emergency response? Fly the plane. Anything that lets a pilot spend more time concentrating on flying the plane is good.

    Proposed Wing Spar AD for PA28 and PA32 aircraft

    in Piper

    Here's the calculation:

     

    Before further flight after completing the action in paragraph (g)(1) of this AD:

     

    ((g) Review Airplane Maintenance Records and Calculate Factored Service Hours for Each Main Wing Spar (1) Within 30 days after the effective date of this AD, review the airplane maintenance records and determine the number of 100-hour inspections completed on the airplane since new and any record of wing spar replacement(s).

     

    calculate the factored service hours for each main wing spar using the following formula:

     

    (N x 100) + [T-(N x 100)]/17 = Factored Service Hours,

     

    where N is the number of 100-hour inspections

     

    and T is the total hours TIS of the airplane.

     

    Thereafter, after each annual inspection and 100-hour TIS inspection, recalculate the factored service hours for each main wing spar until the main wing spar has accumulated 5,000 or more factored service hours.

     

    It will be interesting to see how CASA rewords this into Australian terms. The way things have been said in the videos, the Americans only do 100 hourly inspections for each 100 hours' TIS, but we would do an equivalent inspection annually. So, for Australia, for an underused aircraft (private ownership low annual usage),do you determine the value of N from the number of annuals since new? Commercially operated aircraft obviously have more thatn one 100 hourly per year.

     

    Let's look at a 1968 PA28-180 privately owned. 50 hours per annum TIS. By December 2019, the aircraft will have had 50 annual/100 hourly inspections; N = 50. Its TIS will be 3750 hrs.

     

    (50 x 100) + {[3750 - (50 x 100)]/17}

     

    = 5000 + {[3750 - 5000]/17}

     

    = 5000 - {[1250]/17}

     

    = 5000 - 73.529

     

    = 5000 - 73.6

     

    = 4926.4 Factored Service Hours

     

    You have to be careful with the second component of this calculation. it is only the T-(N x 100) that is divided by 17.

     

    looks like a lot of the PA28 family will be sitting around doing nothing over the next couple of years while the people doing non-destructive testing catch up with the demand.

    AN176 bolts are Close Tolerance bolts with a 3/8" diameter, 24 TPI.   Tool size 9/16" AF. They have a triangle marking on the bolt head. Up to April 1990, these bolts, if steel, were unplated. From then on, they were made with CAD ll plating. Plated bolts have to be replaced with plated bolts.

    In his description of the wing at 1:58, is he correct? I thought the spar was to the leading edge of the wing.

     

     

    Built up areas

    Taken to be approved because those VFR lanes have been set out by CASA.

     

    The Australian Road Rules provides the following definition for 'Built-Up Area':

     

    Built-up area, in relation to a length of road, means an area in which either of the following is present for a distance of at least 500 metres or, if the length of road is shorter than 500 metres, for the whole road:

     

    • buildings, not over 100 metres apart, on land next to the road;
       
       
    • street lights not over 100 metres apart.
