We've been getting some pretty good stupid pilot tricks, now it's time for the mechanics to chime in. I've got a few to share, but I'll start it off by telling about the mechanic who was tighting a few rivets in a wing on a Turbo-Commander. When he was finished he buttoned up the wing, but he left the bucking bar laying in the wing. You guessed it, the very next flight the airplane encountered a bunch of turbulence and chop. When the crew returned to the hangar the wing was beat up so badly that it had to be reskined and painted.

Ah, Pilot/Mechanics...
Most of their pilot friends think they're good mechanics and most of their mechanic friends think they're good pilots. Think about it.

I read this through an NBAA maintenance alert. Some mechanics while doing a phase check on a Citation V found that the potty in the Lav was leveled with a 3/8" socket bit. Hopfully it was a FAA/PMA approved socket set!! heh heh

There was a pair of brand new mechanics that jacked up a 402 on the fuel drains. It worked for awhile but eventually on jack popped thru the wing.

"New" mechanics provide a virtually unending supply of chuckles but the ones from some of those who should know better are beyond comprehension...
I've seen this more than once:
An inspector wrote up a 747 flap as not being properly lubricated on an A check. He was refering to the dry (cherry max) fittings located all over the tracks and fairings.
Unfortunately I also have first hand knowledge of a "federal employee" making note of the same thing while doing spot checks on the ramp at a major Southwestern airport.

Someone please make sure no stick actuators see this post...

Not quite a mechanic trick, but close enough.

The company I flew for over the summer tried to get field approval from the FAA to run their PA-12 Super Cruisers without electrical systems. Sometimes, every little ounce helps, along with simplicity. And removing the starter, alternator, and battery from the system saves about 100 lbs. From a 900lb airplane expected to perform at the limit of it's performance envelope, that's a lot.

The first field inspector denied the application. Why? The boss had the letter on his office wall, framed. "... the engine will not run without an electrical system..." was the reason the FAA gave. That was news to us, as we had the same engines on our J3's and they seemed to run perfectly fine without an electrical system. Needless to say, this matter was quickly resolved, and that field inspector is probibly the head of some FSDO right now as we speak .

Though sometimes on those 95 degree days I wish they HAD denied that application, especially when I was sitting there propping her for 30 minutes!

Mike,
That reminds me of the FAA inspector a few years ago who went around grounding the unairworthy aircraft he came across while walking across the ramp. As I remember, he “red tagged” a single-engine Cessna that had the engine removed and weights placed in the engine compartment to keep it from falling on its tail. Under the comments, he wrote that the engine must be installed prior to further flight – or words to that effect. Duh!!!

This guy also grounded a twin Cessna with Q-Tip propellers for having unrepaired propeller “ground strike” damage. Huh???

The article that I read told that the inspector would be given some remedial training.

Similarly, there were a few MD80's jacked with the fuselage nose jack pad mounted in the water drain hole. Hey if the hole fits.......I suppose.

I saw a guy try to jack a B757 nose gear using the bottle jacks often used on lighter aircraft nose gear (B737, Md80).
He wouldn't have gotten far, but it was entertaining to see him keep pumping while the piston was maxed out, and wondering why it wouldn't reach the jack point. Sure I could have told him earlier, but where else do u get the comic relief.

Hey we've all had our moments!!!

Came to think of something very stupid done by most mechanics. Signing off the aircraft and handing them over to the flight crew. You know they'll break'em one way or another given a bit of time! Big grin

heard about this a few years ago, about the engineer who put up a poster asking if anyone had seen his spanner as it was missing.

It was found lodged between the wing and the aileron on an Air 2000 B757 that had to make an emergency landing because they could only turn left !!!.

A ways back, a few airlines ago, a mech had a pneumatic drill explode in his hand because he was running it off of an oxygen bottle from a servcing cart. He was very fortunate he didn't get hurt ( much ) and they took pictures of the grenaded drill and posted them all over stating "don't let this happen to you blah blah blah" or somesuch admonition. -- It was alway beat into our heads how flammable just about anything can be in contact w/pure O2. Hearing of this "practical" demonstration brought the point home.

Of course. It's job security all around. We break em so mechs have jobs fixing the bent planes. After you fix em we cant let these beauties sit on the ground so we take em out, make some money, and eventually it all starts all over again.

Well, this is a little off topic but back in the day at the FBO I worked at a lot of guys wanted sumped jet fuel to run heaters on, it being in an unnamed city in Michigan. So the company was generally OK about it, even to the extent of me getting a few gallons of avgas to run my Econoline on.

Well there was a guy who would use every opportunity to put a couple buckets under an airplane, sump out five gallons here and there, dump it in the sump fuel tank and heat his garage with a salamander heater all weekend.

Larry, I hope you're reading this.

People started getting pissed off. So one day a plot was hatched. Larry was told that there was ten gallons of the good stuff just taken out of a Citation in the sump fuel tank. Well....sort of. It was five gallons of Jet A, a gallon of MEK, a gallon of toluene, and three gallons of 100 LL.

His garage caught fire and burned down.

Draining the potable water tanks after a flight, one of our quality inspectors asked where the water was coming from.

"Condensation" was the reply.

OUCH...there's a story floating about someone doing a strut service with O2,maybe someone can verify that one!?!...Had a 727 trailing edge nav light inop..unscrewed the three little screws,pulled off the lens,saw the bulb was shattered,told the other mech i needed some needle nose pliers and please shut off the nav lights,came back there was blood everywhere,apparently the mope decided to press his thumb into the shattered bulb and twist it for extraction purposes...he's a lead now!
