I always plug my triple prope every time I remove the probe, because I have had "leaf-roller" bugs build a nest in one afternoon! Wings and Wheels sells a nice little plug with a red streamer attached to it.
For the guy with a ruptured diagram in his ASI, I would bet someone blew out the line with compressed air..............don't ask me how I know this to be the most probable cause? JJ |

I remember watching Les Sebald clean a glass instrument lens out of the cockpit of a Grob. He was blowing the static system out with compressed air, and forgot to disconnect one of the instruments. Oopsie.
I doubt that there is much chance of harm from pressure changes while the static ports are taped over. |

Oopsie. I doubt that there is much chance of harm from pressure changes while the static ports are taped over. Some instruments, like Sage variometers are highly likely to be damaged by the pressure pulse of pulling tape off after a big pressure change. I know from experience. One can tape statics so the top is protected from moisture while leaving a small "wrinkle" below that will allow breathing. FWIW UH |

I made a Pitot cover for my LS6 (fin pitot) with a length of rubber tubing (medical type) that has some yaw string yarn inserted in it, and red tape wrapped around it to make it nice and visible. It is easy to slip over the pitot tube, and any critter would have to go a long way past the yarn to get to the tube.
No critters so far (had them in the past; went to the Grand Canyon once from Turf without any ASI or nav computer - but it was too good a day to pass up!) OT, but when I leave my glider rigged in our hangar with the TE probe in, I slip on one of those red REMOVE BEFORE FLIGHT banners that have a grommet at the end - which fits perfectly on my Ilec TE probe. Easy to see and helps prevent someone hitting the probe in a dark hangar and damaging the in-fin connector. Another reason for TE probes to point UP ;^) Kirk 66 |
