FYI: G100UL is now available for purchase at Reid-Hillview (RHV) https://www.g100ul.com/news/g100ul-high-octane-unleaded-avgas-at-reid-hillview/ To my understanding it is available to purchase right now. $6.99/gal. That is anywhere from $1.50/gal more than 100LL to the same price as 100LL...

I don't think it's an over-reaction: time to a hidden fire becoming non-survivable is 7-35 minutes based on prior examples. The FAA estimates on average only one third of aircraft with a hidden fire may reach an airfield before the fire becomes uncontrollable. Random smoke smell is how most of...

Are you certain? 14 CFR 33.7 just says that "engine ratings and operating limitations are established by the Administrator and included in the engine certificate data sheet". Further the FAA Reauthorization Act of 2018 requires the FAA to offer a process beyond the "traditional means of...

The FAA could issue fleet-wide approval to G100UL or 100R (or both) just like they did for 100LL when 100/130 went away. Right now an FBO can't just order up G100UL/100R because only STC holders can purchase it. That means you need an extra truck and/or tank for the non-STC holders. If STC is...

I wish you could take training and get a "Repairman's Certificate" for a certified aircraft you own. In my view it would be more limited than for an experimental but if you can change the tires, rewire landing lights, replace seat belts, replace fuel lines, etc then why can't you swap an...

The whole revive-GA thing in the 90s was an 18 year limit on liability for this reason. Unlimited liability and service doesn't make sense, especially when the manufacturer can't force you to follow any kind of inspection or maintenance program. A fair point. In fact I wonder if replacing the...

Yeah the way I read this it is the same as it has been: supervising A&P must be present and involved in the process. Blakely v Sugen says it can't just be an A&P on premises (as in available to ask questions) so a shop can't hire one A&P to sit in the office all day while non-A&Ps do all the...

My initial reading of the AD seems to imply that it is not purely an age or life experience issue. To put it more simply maybe your spar will crack at 30,000 hours. Maybe 10,000 hours. It is very difficult to tell because that part of the spar is under stress and the smallest imperfection can...

Given the potential impact I'm hoping Piper charges cost on new spars here, but I can't 100% fault them. This is some black magic wizardry in terms of metallurgy. The larger issue is I have a strong suspicion this AD will continue to expand over time. They only looked at 2800 airframes in the...

https://drs.faa.gov/browse/excelExternalWindow/FR-ADNPRM-2024-21209-00000000000.0001 Forthcoming AD on Piper wing spars for much of the PA-28 and PA-32 fleet. Of the 2800 eddy current inspection reports from the prior interim AD around 100 "anomalies" and 6 fully developed fatigue cracks were...

This is not actually true anymore, at least on the IO-360 used in Cessna 172s from serial number 9491. They added a loop back to the fuel reservoir specifically to help with hot starts.

FOM says for those warnings execute Severe Icing immediately. Escape ice first, notify ATC after. If the FOM says that surely it means things are serious and about to get very spicy if you don't take action, no? I'm just a student pilot so it is hard for me to understand being briefed that we...

The A350, as the largest predator on the ramp, hungers for blood. Normally the CRJ relies on its nimbleness and speed to avoid predators, but this time the A350 approaches from cover behind the CRJ to avoid being spotted... then it pounces! The attack is over in an instant. The unfortunate...

I usually just ask the controller then there is no ambiguity. I ask for a locally known departure procedure or a departure in reference to the pattern (left crosswind, right downwind, etc). On rare occasion if I want to turn early (eg before end of the runway) on takeoff I just ask for it: "XYZ...

ADHD itself is highly variable, ranging from mild to moderate to severe. Response to medication also varies. Someone with mild ADHD who is well-medicated is no danger. AFAIK it's also not a condition that would prevent accurate self-assessment just like all of us do each time we fly. The...

I don't think you understood me. Reading a chart legend is exactly the sort of really really basic thing the test is screening for. My point was very deliberately NOT saying anything about talking to FSS or whether that is useful or not useful. My point is that the chart supplement and chart...

Honestly the written test is nothing but a fool/non-serious dilettante filter. The fact that it is multiple choice, only 60 questions, asks things that any sane person would lookup, etc is proof of that. Its main worth is making most of us students go through some sort of ground school...
