most, if not all system deativations are covered by company modifications, and thus there is no need for a tech log entry.
A company modification is just that. It’s simply a mod that’s been designed in house and approved by the relevant Quality/Tech department. At some point it then has to be applied to an aircraft for certification and record purposes (Task card or Tlog)
Obviously we didn't just decide amongst ourselves that we wouldn't bother with the airstairs, there would have been a jobcard to cover any deactivation which would have been properly stamped and signed on job completion, I said there would be no need for a tech log entry....
Depends where the de-activication took place ! If on a check no Tlog entry would be required as it would be covered by a task card (which in essence is an extension of the Tlog) but on a line station it probabally would be...
Not if the aircraft are delivered to the company and then modified. In this case the company can add a page in its OM-B how is the configuration of its aircraft.
If you wanted to track all modification you made on your airplane, your tech log would be full!
This is a very illuminating thread
If you just add a page in the aircraft OM-B how is the CRS for the work carried out issued?
If you carry out any modification, rectification or work on any aircraft you have to raise an entry somewhere for certification purposes. This work has to be carried out i.a.w with all known procedures (Company, MM etc) then a CRS is issued by an appropriate approved engineer. This work can be on a task/work card if on base check, or if on an outstation/line and the only access is the Tlog it goes in there. Only then when the company Tech records has the information that the mod has be carried out does it go in the OM-B (and not before)
And yes if there a lot of modifications needed to bring the aircraft up to company requirements it’s a lot of paperwork !!!
