    Engine operation: Doing it right
    A builder-pilot related that when he leveled off at 8,000 feet
    and advanced the throttle of the normally aspirated Lycoming
    engine to maximum manifold pressure for cruise, the engine became rough, to the point that he aborted the flight and returned to the airport. He made two mistakes according to Dick Koehler. (Sport Aviation)

    RV BUILDING

    The Holy Cowl

    Getting it inspected
    After you experience the fun of building an RV, you get the fun of flying an RV. Then you get the fun of making changes to the RV. Tom Berge, of Plymouth, Minn., is one of the best at experimenting with and providing data on modifications to his airplane. In this quarter's newsletter of the Minnesota Wing of Van's Air Force, Tom writes, "I started the project around the middle of February expecting about a month of downtime. The basic cowl install was pretty straightforward with few issues. The pressure plenum and carburetor air box turned out a little different. The biggest issue with the plenum was it did not fit the cowl. The inlet spread on the plenum at 24” did not match the cowl openings
    at 23.5”. I noticed the difference early on, but stubbornly kept fighting it, knowing full well what I had to do. The actual fix was a very simple splice. (Read more - pdf)

    Pilot pulled from crumpled plane
    Noel DrewAt first, rescuers feared the worst, but 68-year-old Noel Drew of South Africa was alive and and in a stable condition in the hospital. His RV-6 plane crashed on Sunday, just before landing on a friend's Assegay farm. The power cables lying just metres from the crash site were evidence of the plane clipping them while landing, but a wind-shear may have caused it to hit the cables. (The Mercury)

    Returning to the runway
    Last week, the Hotline presented an article on the 180 degree turn from Chapter 1410's newsletter. That spawned this e-mail from Roy Willis of the Tennessee Valley RVators:
    The graphic and the text indicate a 45 degree right turn and a subsequent 270 degree turn that in a no wind condition brings you back to a 45 degree right turn to align with the runway.

    An old time instructor and examiner taught me and many others a procedure taken from the Navy in World War II. The Navy used a maneuver called the Williamson turn to recover overboard sailors. It was named after John Williamson who devised the maneuver as a Navy officer. Williamson became very prominent in auto dealer circles after WW II.

    The Williamson turn consists of an initial 90 degree turn to the right and a subsequent 270 degree turn back to the left. In a no wind (or current) condition, this brings you back on the reciprocal course of the runway (ship track). Properly done this leaves more time on final for adjustment and requires no subsequent turn to align with the runway as does using only a 45 degree initial right turn.

    In both Private and Commercial training in the early 70's, I practiced both approaches and found the 90 degree initial turn much more comfortable and presented me with a much easier final approach workload.

    The mineral oil myth
    You can spot a hot thread even before it gets hot sometimes. Like this one on VAF, based on an article called "The mineral oil myth" published in 2003. "Aircraft piston engines break-in just fine on ashless dispersant oil, so why do engine manufacturers still require break-in using straight mineral, non-ashless dispersant oil?" It asks. Oh yeah, this one's going places. (More)

    When students in Brian Lussier’s aviation technology class at East Greenwich (RI) High School first saw the small airplane shipped in from New Orleans, a film of grease coated its frame.The single-engine plane — an RV-7, sold in kit form by Van’s Aircraft, of Aurora, Ore. — had been under seven feet of water in its hangar for at least a week in the wake of Hurricane Katrina, in September 2005. It was just the type of clean-up and repair project that Lussier’s students welcomed. (More from the Providence Journal Bulletin

    LETTERS FROM FLYOVER COUNTRY
    FIELD TRIP TO THE HANGAR
    Bob and MahlonWhen you're in a dying industry, it's impossible not to be be very careful about taking the large steps one needs to take along the way. As I am at the "spending big money stage," and since I'm aware I'm in a dying industry, there is a fair amount of uncertainty over the project right now. And yet, I don't care. (More)

    Steve Saint took a flight in an RV-10 down to Ecuador to have it repainted, a new panel and new interior was a great adventure. A non-stop from Costa Rica to Cozumel, Mexico then across the Caribbean to Key West and landed with 30 gallons of fuel, it wasn't around the world, but this sort of trip is an easy "one stopper" for the new generation of Experimentals like the RV-10.

    BUILDER TIPS

    Fiberglassing the canopy
    In one of the next Hotlines, I'd like to feature photos and tips from folks who have made the fiberglass skirt around the front of their canopies. If you want to just send me URLs to existing online pages you've developed, that's fine.

    D-Sub pin extraction made easy
    Let's consider the features and functionality of a typical insertion/extraction tool for connectors having removable pins. In this case, I show a tool for D-Sub connectors. There are semi-standard colors for extraction tools of various application to assist the technician in picking the right one out of the tool box. For the D-sub tool, the white end is for extraction and the red end is for insertion. (AeroElectric Connection... more)

    Chart holder
    "I have seen a few chart/map holders on various posts, and thought I would post pictures of one I made from surplus material and installed in my 9A. It folds up against the sidewall when not in use, and clears the stick in extreme maneuvers. (More on VAF)

    PICTURE OF THE WEEK

    Fernando -- I don't have an actual name that I can find online -- took this picture at the Pennsylvania fly-in. It's a testament to the depths RVers will go to follow some whimsy A honey-themed RV? I never would've thought of it. And I sure wouldn't have been able to design or paint it.
