    SERVICE BULLETINS

    Mandatory inspections on all Slick 4200/6200/4300/6300 and LASAR™ 4700/6700
    magnetos

    Field reports indicate operators have experienced premature carbon brush wear. Premature brush wear can lead to failure of the magneto to provide consistent spark and possible loss of engine power. This bulletin describes an inspection schedule for specific serial number ranges and magneto and brush operating times due to observed variations in premature wear rates. (See the service bulletin)

    FEATURED STORY

    The Jedi Guide to Building an RV
    Jedi Guide to RV BuildingThe longer I build my RV -- and at 7 years and counting, I am building my RV longer -- the more I marvel at the people who built RVs before me, especially those who did so without prepunched kits, Web sites, or electrical power. These are the masters of Planet RV. Fortunately, we are equipped to use their wisdom. Nervous about building? You will be, young RV knight. But the force is strong with you, and the advice is abundant with our teachers. (More)

    Flushing in the cockpit
    Amit's map boxI wanted the map box in my panel to have a flush door, so that it will not protrude from the instrument panel itself. The following implements this idea in a way which is simple, requires no extra support for the door in the open position, and looks nice. The latch I used is also quite nifty and pretty cheap (did I say nothing protrudes?). Read the entire directions carefully before cutting any metal (More from Amit Dagan)

    Saddling up the ponies
    Installing the engineI’m now 2 yrs 3 mo and about 750 MH into the RV-9A project. It took 3 yrs 2 mo 2 wks and 1900 MH to build my Long-EZ. I originally hoped to complete the QB RV project in around 2 yrs….. but then, I hadn’t yet taken the schedule and budget times Pi divided by 2!! (Mike Rhodes in EAA 902 newsletter)

    RV-12 fuselage kits to ship next week
    RV-12According to an update posted on the Van's Aircraft Web site, "We are scheduled to crate the first Fuselage kits October 1st, and begin shipping two or three days later. So far about 110 are on order. Empennage kits are nearing completion and should begin shipping in late November, as soon as the backlog of Fuselage Kits is cleared." (More)

    RV Day tripping
    Singing the blues with an RV-6

    Ashland Kentucky"As neither Rick or I could conjure up a destination for the day, I took the simple expedient of using AirNav.com to find the cheapest gas that was at least 75 miles away. That turned out to be Ashland County (KDWU), Kentucky. The AirNav comments were all very favorable, and we figured the worst case is that I'd buy some gas and we could fly back up north for lunch at Portsmouth." (Papa Golf Chronicles | Video)

    What does affordable flying mean to you?
    Take my RV-10. Sure, building it has been a drain on the checkbook in a steady, significant way over the past four years, but until that engine fired up and the aircraft took to the air those costs were predictable. Then we got the first fuel bills had to replace the electrical components that did not work and a tire. And — well, you know where I am going with this. (Amy Laboda on AvWeb)

    New tour times at Van's
    In an effort to better man the tech-help phone lines and serve a customer base that spans all the time zones on the planet, we are now offering tours/demo rides at specific times twice a day. We will have two tour slots per day. There will be a morning tour at 9:00 a.m. and an afternoon tour at 2 p.m. Other times may be available by appointment but if it is at all possible, we'd ask prospective tourers to show up at the scheduled times. We cannot offer tours after 3:00 p.m. or on weekends. Customers who arrive after the scheduled times may join a tour in progress, or plan to join us for a later tour. Thank you very much for your cooperation. It will allow our tour guides/demo pilots to address their other responsibilities without interruption and result in better service all around.

    BUILDER TIPS

    Paint-booth extractor fan
    Extractor fanAn interesting thread on VAF this week, ostensibly about extractor fans, got me interested in some of the paint booths that people have set up. Certainly better than my surround-the-part-with-a-cardboard-box system. (Thread on VAF)

     

    Aircraft fire extinguisher system
    Fire extinguisher systemI decided to install an engine fire suppression system in my RV-7A after reading an article about fire extinguishers in the August 2008 issue of Kitplanes. I was also inspired by another RV builder who kindly shared his ideas with me. Lots of hot-rod car builders put these engine compartment systems in their cars, but interestingly, not a lot of homebuilders put these systems in their planes. Fortunately, it appears the likelihood of an in-flight engine fire is very low, though I've never seen any statistics on it. Perhaps this is the reason we don't see many of these systems in small piston powered aircraft? (Thread on VAF)

    Nose cowl landing lights
    Landing lightsI did not want my taxi light to be in a wingtip, because of the limited lighting pattern, so a cowl mount had to be designed. The landing lights will be mounted in the wingtips. These two criteria were met. I used MR-16 71 watt bulbs. The taxi light in the nose has a 25 degree pattern, and the two landing lights are 15 degree. The angle of the bulbs are adjustable, the wingtips with screws and springs, and the nose with washers. I use .125" plexi bought from Home Depot to make the light covers. These were shaped carefully using a heat gun over the fiberglass parts before cutting the fiberglass. Doublers were made, shaped, and riveted to hold the plexi lenses. (Thread on VAF)


    PICTURE OF THE WEEK

     

    "Ex Harrier pilot Andy Hill and Warbird display pilot Alister Kay's precision handling makes the photographers job an easy one," the cutline on UKer Andy Hill's Web site. Somehow I think the photographer had a little something to do with this fine pictures. (See more).
