Even our old subs were pretty quiet. In the 1980s, they usually had to augment their acoustic signatures for us (Patrol - P3Cs) to detect and localize them.

I also use the Permatex anti-seize that comes in the tube, based on the recommendation of my A&P/IA. I am careful to keep it away from the electrode end of the spark plug - none applied to the last thread, and use it sparingly. I haven't had any issues in 23 years using it this way.

Wow! You need to hire an exterminator...

I had smoke in the cockpit once - at night. Luckily, the source identified itself immediately - one of the radios, a KX155A. The display was out. Pulled the breaker and the smoke stopped. Turned out to be a burned capacitor. Shortly after, a SB came out to replace them in the KX155A and KX165A...

I have a lot more night time than the accident pilot, and have flown that area a number of times. No way I would fly there at night...

Even though I have plenty of "obsolete" boxes, my philosophy as well...

When my Slicks came due for their 500 hour, I bought 2 new ones. Installed those and sent the old ones to AMS for service. Each needed a few parts (not coils). They sit on the shelf ready to change out quickly if needed. I am a bit of a hoarder - I also have a spare voltage regulator, rebuilt...

The one that annoys me the most is the new designation for NOTAM: NOtice To Air Missions. How the heck does one notify a mission?

Could have been either... Oh yes, I've owned my DA40 for over 22 years. It is one of the items on the Diamond Maintenance Checklist for 100 Hour and Annual inspections. The mechanism is somewhat flimsy, though. The locking pintles press on thin sheet metal actuators that activate microswitches...

"I always thought it was weird that there’s an annunciator for when the front canopy is even slightly open, something the pilot can easily see, and none for that back door." The DOOR annunciator indicates if either the front canopy or rear hatch is unlatched.

Supply chain issues in aircraft parts are certainly more prevalent nowadays. One reason why I try to anticipate the need for wear items (brake linings), routine servicing items (oil and filters), and even hardware. I keep a good supply in the hangar, and reorder to replace used stock. I even...

I learned to fly in one of these (three, actually: N2447K, N2317D, and N2474F). Back in 1980, they allowed spins in them, so I got to learn spin recovery (I learned spin avoidance later). I liked that airplane - in fact, I think I imprinted on it like a baby duck. In 2001 I bought a Diamond...

I also was surprised at the amount of fire. This may be the first survivable DA40 accident that had a post-crash fire. The pilot stated he had about 30 gallons of fuel (Jet A) on board. I found this report which has a lot of good information regarding the flammability of Jet A in aircraft fuel...

Installed one of these 2 years ago to replace my mechanical AI (which didn't, by the way, have adjustment capability to alter the position of the airplane symbol index): https://www.kellymfg.com/images/RCA2610%20information.pdf This has a "Pitch Sync" feature which allows resetting the...

Aside from eBay and salvage yards, I've seen them as NOS at some supply houses: https://www.electronicsurplus.com/meletron-71558-31-3-switch-pressure-aneroid-switch-28vdc-3amp...

My Scout would disconnect 1-2 times an hour. Gave up and bought a Sentry Mini. Better, now only once every couple of flights. I moved its mounting position to have a more direct line-of-sight to my iPad. My seat shells are carbon fiber, and I thought that they might be interfering with the WiFi...

Not an A&P, but... The magnetometer (KMT112) on my DA40 is mounted on an inspection cover on the right wing. The cover is attached with three brass screws, instead of the stainless steel ones used on all of the other access panels. This is a factory-installed system (Bendix/King).
