Try bottom jug replacement on a R3350 compound engine (Connie) in the dark in pi----- rain, those lockclips on the cylinder
were invented by a nutter.

Bristol Freighter - esp changing exhaust stubs.
DC10 Leading Edge Slat cables (loved the rest of the aircraft though)
Anything on a Devon
Metro engine control cable change (under the cockpit floor)

b757 door mechanism bearing replacement ,what a night mare, has to be done nearly every c-check on at least 2 doors.
you also need need hands of a baby to get through the small access holes.
also changing the r/h engine P R S O V.with the special pri-bar tool.
apart from that not a bad kite....
b737 classic inbd flap boom cables ,tring to figure out how it fits around the pulley system,always a good job for the new boy in the hangar.

Lets be honest here,

Any aircraft that you are working on at 2 o'clock in the morning in the freezing cold and the rain driving at you with that trickle that drops down your collar,right down your spine and makes you feel totally ticked off has got to be the worst.

It really doesnt matter who makes it at that time or what the job entails I can say from experiance you will not want to be there doing it and wont relish the fact this is what we all do for a living.

But it is and we do,at times it like trying to thread a needle,in the shower and blindfolded.Personally I think this should be a fundemental part of any apprenticship in this business as you can be sure it will happen to you when you are older.

To spice it up a bit when practising get someone to keep ringing you mobile phone or asking you when you will be finished (Whilst drinking a coffee in front of you).If you can cope with this you will make an admirable engineer and there are lots of lads out there that do this every day/night of the week.Keep it up lads

Learjet 45 cable changes!!Pain the A%&e!!Ony Bombardier would install fairleads that wear the cables !!

I'm intimately familiar with the cnt tanks on the F28. The stupid little snaps that are just out of arms reach. BAE146 cnt tank feels like you are lying on your head as you go in, but had ok room inside. 727-100 cnt tank will kill someone if it hasn't already. The access hole is too small, and is half blocked by the aircon duct. And I hate to lace the tanks. I rather F28 snaps, just wish I had longer arms. C130 Bladder tanks aren't bad, lots of room. I came close to death in a 737-200 wing tank trying to get to the MLG casting. I got stuck, had my light break, and my mask got a leak. My manager told me to go in through the wing root access, I told him I wanted to go in through the centre tank access, but he didn't want to have the A/C defueled. He knew best. Ha Ha. Ended up doing it my way, because I refused to do it any other way. I also once got my head wedged between some ribs in the outbrd tank of a C130, and had to get a couple of guys to pull me out.

The dialogue of this story needs to be done in fairly broad Yorkshire brogue. The man that said it is not a youngster and was my Station Engineer in the 70s his initials are JS. I was whingeing about a job and he took a few seconds to adjust my attitude. He said look here-when I saw a 1-11 for the first time I didnt just see an airoplane - I saw a Ouse. When I saw a VC-10 for the first time I didnt just see an airoplane I saw a detached Ouse with a river in the garden. When I saw a Tri-Star I saw a B---dy great mansion in 3 acres with a river in the garden and a Golf course around it. 737 airstairs are not that bad as long as you are not on your own of course.

Nothing can beat the F111,
I don't know how they managed to get the skin on.
Park one and 10 minutes later there are puddles of oil and fuel everywhere

Hughes 500... 500 reasons not to work on one. S76 how many screws do you really need for the cowlings??? but I got to love those AS350 Squirrels, easiest helicopter to ever work on!

Whoever thought of those Raychem connectors on the 146 wants neck shooting at birth, My vote....Jetstream 31 bloody 'orrible contraptions, my back still hurts from replacing the windshield heating controllers :{

BAE 146 windscreen wash solenoids, I will have my bottom ribs taken out (mick Jagger style) for next time I have to do it

I agree with four_two, the 1,11 was terrible, almost every job, but especially the csds & the bleed air duct in the stub wing.
The worst thing about the Belfast was the absence of anchor nuts, just 4BA loose nuts everywhere. The 146 is not good either, the duct from the fresh air louvres fan, under the rear floor sticks in my mind.

S.B.

i heard that the BAE-ATP was also a bit of a nightmare, any horror's on that please tell us.

I will start on the ATP before all the rest of the guys jump in.
High on the list has got to be the heated intake duct for what passes for an engine. OVER TO YOU BOYS

worst aircraft
 

Has anyone ever tried working of Harrier GR 7? If you have you will know that whoever designed the thing forgot about engineers. The GR 7A is even worse with about 1" either side to get an engine in and no room to work unless you are very snake like!:{

Wirelocking the slats on a 757 after rigging them is a bit of a chioce job as is the pack flow control valve on the A320 , i would love to meet the person that decided to put it on top of the pack.

Saab 340 park brake cable, I wouldn't wish that job on anyone. Oh, and anything relating to the bleed air/ anti- icing ducting on a F100, my particular fave being the PRSOV in the stub wing.

Any a/c with a faulty toilet:{

Oh yes fwd toliet tank replacement on a L1011 must be also done in Saudia during the day to get the full effect, did two
never forgoten.

"as is the pack flow control valve on the A320 , i would love to meet the person that decided to put it on top of the pack."

codpiece face

Try attacking it from the front, along the supply duct, instead of bellow, make's life a whole lot easier.

The BAC 1-11, Jacking it to work in the Pack Bay's, doing anything in the stub duct area. 2 small noise generators at the rear.
