Hi group, There are larve in my static ports again. Disconnect the static line as close to the static port blockage as possible and blow out (not toward the instruments). Depending on the type of bug, you may not have any other choice but compressed air. There's some type of larvae that find the tiny static hole in my pitot blade to be just the right size for growing. They build some kind of goopy cocoon in there. Every time I've blown them out it took more that 120 lbs. of pressure to get them to budge. Good luck, John Galban=====N4BQ (PA28-180) OWE!!! John, 120 psi? That sounds like overkill. But if that's the only way you can get them to budge... What kind are they? I have a PA28-180 and it sounds like I'd hate to get those. Especially since everyone seem to be forgetting one thing: The rules say that if you open the static system AT ALL, you have to reperform the IFR certification test. Ka-ching -- $100 or so down the tube. Chuck N7398W |

Thanks Chuck,
Knowing myself, I'm completely capable to forget something like that, whatever I try. On the other hand, from the little experience I have I know a plane flies perfectly well with blocked static ports :-( So, I'm not too worried about that, since I only fly day-VFR. But I'm going to try your suggestion anyway. -Kees |

I just recently saw an episode of "Air Emergency" that talked about an
Air Peru flight (I may have the details wrong). Basically a 757 take off at night over the dark ocean and no static system. The pilots never figured out the problem. They knew their instruments were wrong but they assumed ATCs altitude readout was correct (which it wasn't the transponder is also served by the static system). In short, the cause was a $1/hr aircraft washer who put duct tape over the static ports before washing the plane. Boeing ended up sending a lot of money to family members. The interesting thing is that the 757 maint manual says to only use special Boeing tape (bright orange) when coving up static ports. -Robert |

It's always troubled me that the pilots never figured out the static ports were blocked, and didn't know the transponder altitude was based on the static pressure. I've wondered whether that part was true, or whether the truth was altered for dramatic effect. It's just inconceivable to me that they didn't know these things. 'course, I wasn't there. Dave |

Dave If this is the same episode I'm thinking of, the co-pilot did figure it out, and told the pilot that the corrections were not going to work. The Pilot basically told the co-pilot to keep his place. If I remember correctly, this brought up new rules regarding the ability of the co-pilot to take control from the pilot in such cases. -- Mark Hansen, PP-ASEL, Instrument Student Sacramento, CA |

With the ability of skumbag attourneys to convince a hand-picked dufus jury that the evil big company needs to pay the dead and injured, no matter who is wrong, things like that will continue and all us consumers and stockholders pay. Besides, it's a bunch easier to file suit against a US company than a foreign airline. Case in point - In the firestone tire suit for over $1B, the parties to the class got a coupon for $40 or so off their next set of tires. The lawyers got the rest. How many of you non-attourney smokers benefited from the tobacco suit? I know one lawyer that purchased a $30M Gulfstream with his part of the settlement. You think the companies paid for this? Nope - us consumers. Even if you don't smoke your insurance bill went up and mutual fund went down.

Yep, when 60, 80 and 100 lbs. didn't work, I just kept bumping it up. BTW - when the clog finally lets loose, it's like some sort of explosion. I've never been able to tell what kind of bugs they were, since the only thing that comes out is a big blog of orange goo. I just know that whatever they are, they do their nesting here in central AZ in June and July. Especially since everyone seem to be forgetting one thing: The rules say that if you open the static system AT ALL, you have to reperform the IFR certification test. Ka-ching -- $100 or so down the tube. Fortunately, that's not a problem for my VFR bird. If I had to re-certify every time it happened, that would just be adding insult to injury :-) Usually, the tennis ball I keep on the pitot blade does a good job of keeping them out, but every time I've forgotten to put it on during the nesting season, I've been hit.
