Re: Weekend Feild Annuals

Inventory isn't that bad, sure you need lots of stuff but it's manageable In past times, I maintained an airworthy parts stores, for fabrication I did for specialty aviation customers. I had the advantage of nearly always knowing before I needed it, what I'd need, and some extra budget to stock a l...

Re: Shock Cooling a myth?

Did you manage to cause detonation in small engines as well? Such as O320 or IO360? Is there a difference in lycoming vs continental? I did not test those models. I would expect the O-320 to be fairly detonation resistant, as it has a very low compression ratio. IO-360 Lycomings come in different v...

Re: Shock Cooling a myth?

Though shock cooling and detonation conditions are not normally discussed in the same sentence, it seems that they have been drawn together here. Firstly, read the flight manual, and fly the plane the way it describes. Be as gentle as conditions permit, because of your own sense of pride of airmansh...

Re: Cargair Aztec 18 June 2019

Too fast hands. An Aztec will overshoot just fine with half flaps, and even with full flaps, though less well. If in doubt, leave it alone until there is less criticality. I hope that the instructor passenger was not intending to retract the gear while on the roll, thinking to myself "Positive ...

Re: Shock Cooling a myth?

I've never seen a benefit in using an uncertain outcome to attempt to justify not being easy going on an engine, and airplane, or any machine, for that matter. Plan ahead, and be gentle on the machine. For those [hopefully]rare occasions when things surprise you, do what you have to do to assure a s...

Re: Weekend Feild Annuals

As long as you've thought it through, and have a plan for the known and predictable, the unpredictable will have to be handled as it comes along. It's rare that everything is perfect for aircraft maintenance, we do the best we can. I just like to start things toward being easy and comfortable. I fin...

Re: Weekend Feild Annuals

The only way I can think of to be sure that there's no concern about a potential conflict of interest, is to have an open, and complete discussion with your day employer. If the employer has no concerns, you probably have no concerns. I'd make sure there's a written record of that discussion... I ca...

Re: Weekend Feild Annuals

Ahramin's advice is excellent, so I won't repeat it. That said, for the most part, you'll encounter two types of GA owners: Unable to truly afford their plane, and amply able to afford their plane. Owners who can't afford their plane, as sympathetic as you may feel, will not willingly pay you for th...

Re: How do you value yourself as a low time pilot?

Your work ethic, strong back, flexibility, ability to take constructive criticism and willingness and ability to learn. There's the key. At least for the Ma and Pa operations, you're looking for the boss who says to you: "I will never ask you to do a job around here that I would not do.",...

Re: Latest Cessna tail AD

This AD is mandating an inspection which should be being done anyway. I've seen several 180/185 with defects in this area (worn or cracked "hockey sticks". There is an after market source of replacement hockey sticks, as Cessna's seem to have become very expensive. They are not all the sam...

Re: O-200 cold weather starting

The debris inside a pump should be only ultra-fine dry graphite powder worn off the vanes, by design, which lubricates them. The debris in the pump could also include engine oil mist which has been drawn into the pump, This oil mist mixes with the carbon dust, and cam produce a sticky sludge. Depen...

Re: O-200 cold weather starting

Most vacuum pump vanes are angled so as to "trail" the rotational axis. Okay when turning forward, as they will tend to lift themselves over debris or imperfections in the vacuum pump bore. When turned backward, the vanes can tend to bind into gunge in the bore of the vacuum pump. They, an...

Re: Carb fire season

I am curious if you know if the primer was originally designed to be also used on a (rough) running engine as opposed to only during start? The POH says: "Continue to prime the engine until it is running smoothly, or alternatively, pump the throttle over the first 1/4 of total travel." I'...

Re: Carb fire season

Why can't you pump throttle? What are risks, damage? Well, to begin with rapidly changing the throttle setting on an engine you're trying to get to idle nicely is counterproductive. That said, carbs with an accelerator pump (most) will squirt a stream about like a water pistol, when the throttle is...

Re: Carb fire season

This O-200 is configured with a primer nozzle on each cylinder injection port, rather than one nozzle above the carb, so I too was surprised that fuel could find its way back to the carb and airbox, but, they are down hill! No, I don't pump the throttle, the accelerator pump is not designed to work ...

Carb fire season

Yeah... it's carb fire season. I was starting the 150 to take my grandson flying this morning. I'd left it plugged in all night with the engine blanket on, so it was nice and warm in the hangar. The air wasn't though. I had it running after start, though not as smoothly as I wished, I think I'd fros...
