| Jul 20, 2021 at 22:21 | comment | added | JScarry | @KennSebesta I don’t think the autopilot issue is on point. Mike Busch does point out that “If deactivation of the inoperative instrument or equipment involves maintenance, it must be accomplished and recorded in accordance with Part 43 of this chapter;” so if you can persuade an A&P to sign off on a faulty alternator or remove it before flight then I suppose you would be satisfying the letter of the FARs. I’m fairly certain that my A&Ps wouldn’t sign off on that without figuring out why the alternator wasn‘t working. Was it really the alternator, something else in the circuit, the gears? | |
| Jul 20, 2021 at 21:34 | comment | added | Kenn Sebesta | This might also be relevant to understanding whether the specific plane in question is airworthy with an inop alternator: aviationattorney.com/publications/… | |
| Jul 20, 2021 at 21:20 | comment | added | Kenn Sebesta | @JScarry I see your point. Since we know it's not on the MEL and there is no KOEL, then these do not limit the poster. In the absence of those two lists, resources.savvyaviation.com//wp-content/uploads/articles_eaa/… gives a very good breakdown of determining which equipment is necessary to be considered airworthy. aviation.stackexchange.com/questions/72207/… asks a similar question. | |
| Jul 20, 2021 at 20:56 | comment | added | JScarry | @KennSebesta The plane was certified with an alternator. Not having a working alternator would mean that it doesn't conform to it’s type certificate—hence unairworthy. Unless there is a KOEL that says that you can fly without it, my default assumption is that it’s required. If anything bad happened on the flight §91.13 Careless or reckless operation. would probably apply too. | |
| Jul 20, 2021 at 20:26 | comment | added | Kenn Sebesta | @JScarry how do you come to that conclusion? What if the fuel will run out before the battery does? Many planes do not have alternators and simply charge their battery on the ground, e.g. aerobatic planes where the weight is considered a liability. | |
| Jul 20, 2021 at 18:31 | comment | added | JScarry | If you don’t have a working alternator I don’t see how the airplane is airworthy. You can mark some things as inop, but I can’t imagine that an alternator would be one of them. §91.7 (a) No person may operate a civil aircraft unless it is in an airworthy condition. | |

| Jul 19, 2021 at 18:48 | comment | added | user4867444 | @Pondlife I stand corrected, my bad. Just double-checked mine's POH though, no KOEL. | |
| Jul 19, 2021 at 18:01 | comment | added | Pondlife | @user4867444 Some C172S models do have a KOEL, and it lists the alternator as required for day VFR. Yours may not, of course. | |
| Jul 19, 2021 at 17:30 | comment | added | user4867444 | @Pondlife fair enough :) C172s don't have any KOEL or minimum equipment list, so the only thing that applies for day VFR flights is the old ATOMATOFLAMES. As long as the beacon is on (anti-collision), it doesn't need anything electrical on to be legal. | |
| Jul 19, 2021 at 17:26 | comment | added | Pondlife | @user4867444 Well, if the alternator is required for the aircraft to be airworthy then you'll need a ferry permit in any case. That's why I'd start with that question and go from there. | |
| Jul 19, 2021 at 16:44 | comment | added | Ron Beyer | ATC can issue you a clearance or waiver, call them up and explain what you need to do, chances are you'll be told to go ahead but coordinate with them. | |
| Jul 19, 2021 at 16:03 | comment | added | user4867444 | @Pondlife I do think the mode C is relevant. If it wasn't for that, I would only need the beacon to be legal, and use the backup radio for comms; so I wouldn't really think twice about it. | |

| Jul 19, 2021 at 15:53 | comment | added | Pondlife | Welcome to aviation.SE! I think the real question here isn't about the mode C veil, it's whether a C172 with an inop alternator is airworthy. | |
| Jul 19, 2021 at 15:25 | comment | added | user4867444 | And it's less than 10 miles flying, but it's on the other side of a lake, with a big city in the middle, driving. Usually 40-50 mins with traffic, so my usual A&P isn't too keen on making the trip. | |
| Jul 19, 2021 at 15:21 | comment | added | user4867444 | A&Ps are in short supplies around here, and not lacking for work at all. So traveling to a plane is a deal breaker for most if not all of them; I've had no luck finding any so far. | |
| Jul 19, 2021 at 15:19 | comment | added | GdD | That's a bad idea, even if it's legal, deep-draining a battery is a good way to ruin it and cost you more money. If you're so close to your home base it shouldn't be hard to get an A&P to replace it | |
| Jul 19, 2021 at 15:19 | comment | added | Ron Beyer | No A&P able to travel to the aircraft? | |
