Before he does that he should take voltage drop measurements across the starter contactor. Takes a few minutes but could save a lot of...

Checking and adjusting system voltages in an airplane is ideally done with a calibrated meter. A cheap meter from Harbor Freight isn't...

He implies in his first post that all the CHTs were running high. This thing needs addressing before further flight. Something like a...

Bad engine grounding between the crankcase and/or alternator case and firewall. Alternator output will find other paths to the airframe...

Nope. Not even close. I worked on many flight training 172s, including some from the 1960s, and never encountered a rebuilt one. This is...

That there. It's right in the service manual's inspection checklists: The "7" refers to the 500-hour line in the notes at the end of...

The factory NDIs everything being reused. Everything. They use magnaflux, zyglo, eddy current, dye-penetrant, and other methods to...

Same thing everywhere. Most are guessing at what failed without knowing the systems or structure or anything else about the airplane...

The pilot can hear the starter spin if the Bendix is stuck. All the OP heard was a click. The only effective way to clean that Bendix...

So he doesn’t get burned if his VR goggles short out.

The US Navy just stuck a finger in the eye of every aviator who puts skin in the game. Shameful.

It sure can be a bad thing. For instance, there is a constant stream of stories about electrical system problems on owner's airplanes...

If it was a really weak battery, the contactor would chatter. That's caused by the starter's low resistance causing enough of a voltage...

That says that the contactor's plunger is moving, but the lack of action implies either worn-out contacts in the contactor, or the...

Drilling out the holes weakens the prop tremendously. There is as much as 40 tons pulling outward on each blade, plus eight other...
