Nutloose
And Civi wise you have your own tools. Trust me the best form of tool control is having to pay for them, trust me loosing a screwdriver at over £60 a pop makes sure you don't.
That's why at a nth yorks ex tonka base you were not allowed to park a tonka (no matter how desperate for space) in a half empty grob hangar. AC under MAA rules cannot be housed with AC under CAA rules because of the very reason of tool control. A rule that seemed to 'fly' out of the window when away from an RAF base.
Don't get me wrong, my tools are not thrown willie nilly into a tool kit, everything has its place and are marked with my initials so i know exactly what is and isn't there. There was a case a while back and my heart went out to him of a Yak that spun in and killed them, a Dumpy screwdriver was found in the wreckage jamming the Elevators if memory serves me correctly, a young apprentice immediately owned up to it being his, but he hadn't worked or used it on the aircraft, one possibility surmised was the pilot may have taken it out of the lads tool kit to do up a couple of panels, put it in his pocket where it fell out during aero's and migrated down the tail.. That poor lad has to live with that.
Found it
A trainee mechanic at the maintenance organisation, upon hearing that a loose article had been
discovered in G-YAKW, came forward and declared
that he had lost a short-handled flat-bladed
screwdriver matching the description of the item found in the aircraft. The trainee had started work at
the maintenance organisation in September 2002 and had not worked on LY-AKW during its 50 hour
inspection. However, he did work on the aircraft in November 2002. He does not recall ever using
the screwdriver on the aircraft and only remembers using it to open a tin of paint away from the
aircraft. Indeed the trainee was never given or accomplished a task that would warrant the use of such
a screwdriver. This type of screwdriver is only used on tasks in difficult and restricted areas. The
maintenance organisation also claims that screwdrivers of this type are seldom used during normal
maintenance carried out on the aircraft. Subsequent testing of the screwdriver removed from the
wreckage, however, revealed DNA matching that of the pilot. This indicated that he had touched it at
some time prior to the accident.
The trainee's personal tools were located in two separate tool boxes at the back of the maintenance
hangar. The tool boxes were never locked and were left open during the day but closed at night. The
trainee had been made fully aware of the dangers of loose articles in aircraft and was reminded of this
on many occasions by the more senior technicians and licensed aircraft engineers (LAE). The
borrowing of tools did take place at the organisation and the policy was for the owner to be asked
before hand, but if the owner was not present, items could be borrowed without his knowledge. The
owner however remained responsible
for his own personal tools including ensuring that they were all
present and correct. There was no formal tool control at the maintenance organisation.
