I was checking out the new hangar at JFK and noticed the techs there are using these custom cable holders ziptied to the racks instead of the standard velcro straps we use. They said it cuts down on troubleshooting time when you have to trace a wire bundle. Has anyone else seen this setup or tried it in their own bay?
I was doing a routine check on a King Air at Atlantic Aviation in Scottsdale and popped open a panel I hadn't touched in 6 months. Found green crust on a cannon plug that looked fine from the outside but was ready to short out. Has anyone else been catching corrosion hiding inside sealed connectors?
I was fixing a comm issue on a King Air 200 last Tuesday and the factory wiring diagram just didn't match what I was seeing in the panel. Pulled my hair out for like 3 hours tracing wires that went nowhere. My mentor Tom who retired 10 years ago gave me this beat up 1987 wiring book before he left and I almost threw it away. I cracked it open out of desperation and it had the exact correction for a modification the factory never updated. The old timers really did know their stuff about keeping paper copies of everything. Has anyone else run into factory diagrams that were flat out wrong for older airframes?
I was just doing my usual connector work on a C-130 harness and realized I hadn't messed up a pin in over three years. Has anyone else kept track of something weird like that without planning to?
The Garmin was way more expensive (around $8k more), but the touchscreen interface and auto-slewing saved me hours of button mashing during my last IFR flight. Has anyone else made the switch and regretted not doing it sooner?
I spent $400 on a portable avionics test set last spring because I thought it would save me time on troubleshooting. Turns out it was too complicated for the work I do on older Cessnas at the base in Wichita. After three weeks of fighting with the menus and cables, I went back to my old multimeter and signal generator. Has anyone else bought high-end gear that just sat in the case gathering dust?
I used to just use my regular meter with alligator clips for troubleshooting. Then last month I had a weird intermittent on a King radio in a 172. Wiggling wires while trying to hold probes was a nightmare. Broke down and got the Fluke i410 AC/DC clamp. Took maybe 10 minutes to find a failing power wire that was drawing 3 amps more than spec. Would have taken forever without it. Anyone else find a tool they thought was pricey but ended up being worth every penny?
Fried the PFD display for about 10 seconds until I slapped the breaker back in, and now I always pull the breaker and wait 30 seconds before touching any LRUs does anyone else have a near miss story like that with glass cockpit stuff?
I was swapping out a busted GPS antenna on a 737 at Boeing Field and had all my tools laid out perfect... the weather even held up for once. Got the job done in 3 hours flat with zero rework, which never happens for me on those tight bulkhead runs. Has anyone else had a shift where the plane just seemed to cooperate?
I was doing a routine inspection on a 737 at a regional airport in Mobile and popped open the avionics bay door. There was a whole bird nest crammed in there with twigs and grass wrapped around some wire bundles. The crew said the plane had been sitting for three weeks and they had no idea. Has anyone else found weird stuff in those bays?
Last month I was pulling my hair out at Hangar 7 in Phoenix trying to figure out why a D-sub connector kept failing continuity. Turns out my old AMP crimper was worn out and I'd been crushing pins instead of crimping them for like 2 weeks straight. Cost me a full re-do on a 50-pin harness. Anyone else ever get burned by a tool that looked fine but was actually shot?
Was working on a King Air panel last month. Those cannon plugs had green crust all over the pins. Shop wanted me to replace the whole harness, like $1200. Tried DeoxIT D5 on a hunch from an old forum post. Scrubbed each pin with a fiberglass pen first, then hit it with the spray. Worked perfect. Anyone else have luck with contact cleaner on old corrosion?
I was in a rush before a test flight and figured a paperclip would be fine to clear out a blocked pitot tube. Turns out I scratched the inside just enough that the readings were off by 3 knots for the whole flight. Anyone else learned the hard way why they make those plastic cleaning kits?
I was double checking an old Cessna 172's pitot static system and found out the factory wiring diagram had the ground loop pinned wrong on the connector. The plane had been flying like that for 20 years, no one caught it. I only found it because I was chasing a weird airspeed reading and pulled the pinout sheet from the manufacturer's archive. Turns out a revision in 2003 changed the pinout but nobody updated the old birds. We had to rewire three planes on the line after I flagged it. Where do you guys keep your wiring revisions? I swear half our hangar still uses photocopies from the 80s.
Kept losing satellite lock on a 172 during turns, and swapping the antenna did nothing. I checked the coax and it was fine, but the mount had rust under the base from 15 years of moisture. Ran a dedicated ground strap from that mount to a clean spot on the frame, and the dropout vanished. Has anyone else seen corrosion mess with GPS signals like this?
I was working on a Cessna 172 last month and had to fix a broken wire in the wing root. Couldn't decide between crimping with a standard tool or soldering it right there. I went with the crimp because I was worried about heat damage to the surrounding wires and the plane was due out in 2 hours. Turned out fine, passed the pull test and everything. But now I'm second guessing if solder would've held up better over time. Anyone else run into this choice and regret one way or the other?
Had a guy in Pensacola who'd been doing avionics since the 80s. He told me to use a tone generator and probe instead of chasing wires by sight in tight spaces. Saved me 2 hours on a 737 harness repair, anyone else use that method?
I was doing a routine check on a Cessna 172 last week in Nashville and found cold solder on the coax connector for the GPS antenna. The plane had just come back from a 3 hour flight with no issues, but the signal was intermittent during taxi. If I hadn't caught it, that could've caused a missed approach in IMC conditions. Weird thing is it looked fine from the outside until I flexed the cable. Anyone else seen these cheap pre-made cables with bad solder from the factory? I'm thinking of just making all my own from now on.
Got called out to a 737 in Oakland last Tuesday for an intermittent autopilot issue. Found a loose ground lug on the No. 2 FCC that was barely hanging on - looked like someone rushed it during a C check. Had to re-terminate three wires in that tray, and the crimper I borrowed from the shop there made mine feel like a toy. Has anybody else had a day where one bad connection makes you wonder how many others you've missed?
I’ve been working on this batch of 10 radio modules for a Cessna upgrade, and I set a personal record today. 500 joints checked off the list, all passing continuity and visual inspection on the first go. That’s a big deal for me because I usually mess up at least 3 or 4 from rushing or bad lighting. Took about 6 hours of steady focus with my Hakko iron cranked to 700 degrees. Anyone else keep track of their no-rework streaks for something like this?
I finally figured out why half my DB9 connectors would come loose during vibration testing. Turns out I was putting the contacts in from the wrong side of the tool. A senior tech at the hangar in Denver watched me do one last Tuesday and just laughed. He showed me the little arrow on the die that I'd been ignoring the whole time. Felt like a total goof but at least my terminations are solid now. Anyone else have a moment where a small detail in a crimper or pin tool made you rethink everything you knew?
Honestly I thought those $40 handheld signal generators from Amazon would be junk but I used one yesterday to trace a faulty coax run on a Garmin G500 setup in a 172 and found the break in 15 minutes. The old method of just eyeballing and swapping parts would have taken me half the day. Has anyone else found a cheap tool that actually held up better than expected?
Crossed 10,000 logged hours last month on a King Air 200 down in Phoenix. It hit me harder than I expected, like a weird mix of pride and realizing how many landings could've gone sideways. Anyone else get that hollow feeling after a big number like that?
Was chasing a intermittent short in a King Air 200 the other day up in Bangor, Maine. Tried the standard wiggle test and continuity checks, nothing showed until I used a thermal camera on the breaker panel - spotted a hot spot on pin 12 of the master relay in like 2 minutes. Anyone else use IR tools for this kind of thing or still stick to the old multimeter method?
He was saying someone at his shop installed 20 fake D-sub connectors on a King Air last month and they started arcing after 50 flight hours. Has anyone else run into these knockoffs from certain online suppliers?
