    Flying with worn valve guide and/or worn rings?

    FYI, the broken ring in the picture is the second compression ring, not the oil ring. However, it does act as an oil scraper and can have an effect on consumption as you noticed.

    Flying with worn valve guide and/or worn rings?

    Lycoming's limit for oil consumption is 0.006 x BHP x 4 ÷ 7.4 = Qt./Hr. They do not say whether BHP is the rated power or the operating power e.g. 65% of rated. So let us take the smaller number: .006 X 180 X 0.65 X 4 ÷ 7.4 = 0.38 Qt/hr. This is almost double your actual rate of 0.2 Qt/hr...

    Cessna Generator Troubleshooting

    A couple more suggestions: 1. When you polarize the generator, ground the field through an ammeter and check for around 2 amps of current. 2. I would not trust the months old inspection, as a failure could have occurred since. Remove the generator and re-inspect brushes, springs and...

    Engine overhaul on a stand

    Automotive engine stands attach to the engine at the back where the clutch or transmission bell housing bolts on to it. I don't see how this would work with a typical aircraft engine. That said, my O-300 overhaul manual shows the engine on a stand which places the crankshaft horizontally. No...

    Dangerous request from airport manager?

    I beg to differ. 91.126 indicates it is regulatory: § 91.126 Operating on or in the vicinity of an airport in Class G airspace. (a) General. Unless otherwise authorized or required, each person operating an aircraft on or in the vicinity of an airport in a Class G airspace area must comply...

    Dangerous request from airport manager?

    I am afraid my handle is misleading. The airport is in USA. FWIW, "traffic pattern" is USA specific, in ROW it is "traffic circuit".

    Dangerous request from airport manager?

    I got the following e-mail from my home drone manager: Good morning all, As the area resident population continues to grow, so do varying appreciations for aircraft noise. As stewards of aviation, practice and repetition of flying skills is paramount to safety and enjoyment. However, the noise...

    N/A, FM antenna question, FM neck-loop

    OP, looking at Listen's literature it appears they have two 72MHz transmitter models, one with a vertical whip for smaller buildings and one with a horizontal dipole for larger buildings. I will assume you have the dipole since there is talk about moving it. They may be unwilling to move the...

    Piper Arrow at tie down with dead battery...how to charge?

    True, but the generator's ability to start itself is not much help in an airplane with a totally dead battery. The master contactor is energized from battery voltage, so you would not be able to connect generator to battery and start charging.

    What is inside the puck of a VOR/ILS antenna?

    Most likely a "balun" as stated here: https://sarasotaavionics.com/avionics/av520 The "cat whisker" type of VOR receive antenna is a dipole, i.e. has two elements and no ground. As such it is considered BALanced. The coaxial cable used to connect it to the receiver is UNbalanced since the...

    Hidden stealth aircraft antenna

    Balderdash! There are many competently designed antennas which operate at well below 50% efficiency due to size and cost considerations. An aviation related example is the NDB transmitting antenna. Here is a link to a paper describing one...

    Cold Start Screw up?

    I have read in several places that some kind of polymer coating is being used to address start-stop operating conditions, for example: https://www.sae.org/publications/technical-papers/content/2012-01-1966/

    Oil drain for piper arrow

    Seems to me that your "quick" drain is more trouble than it is worth. Have you considered replacing it with a standard (non-quick, screw in) drain plug?
